In the late 1970s, rubber foam insulation materials began to use building energy conservation in some developed countries. The mandatory construction industry implemented energy-saving standards in new buildings, using rubber-plastic insulation materials, and the application of rubber-plastic insulation materials in developed countries. The emphasis on building energy efficiency and some effective measures have been taken, and these countries have achieved great results, and building energy consumption has dropped significantly. For example, after using rubber and plastic insulation materials in Denmark, the heating area increased by 30% in 1985 compared with 1972, but the heating energy consumption was reduced by 3.18 million tons of standard coal. This shows that foreign building energy conservation regulations have been remarkable for more than 30 years. Social and economic benefits.
Rubber and plastic insulation material is elastic closed-cell elastic material, which is soft, resistant to winding, cold, heat, flame retardant, waterproof, low thermal conductivity, shock absorption, sound absorption and other excellent properties. It can be widely used in central air conditioning, construction, chemical industry. , light textile, metallurgy, transmission, vehicles, electrical appliances and other industries and parts of various types of cold and heat medium pipes, containers, can achieve the effect of reducing cold damage and heat loss. In addition, the construction is simple, the appearance is neat and beautiful, and the product does not contain fiber dust, and does not breed any harmful substances such as mold, so it is a high-quality cross-century new generation thermal insulation material.
The promulgation and implementation of rubber and plastic insulation materials and products and energy conservation regulations are the influencing factors affecting building energy efficiency, involving a large industrial group. The development and application of building rubber and plastic insulation materials are receiving more and more attention from all over the world. Materials are constantly emerging. From the perspective of the materials and varieties of building rubber and plastic insulation materials, the research on rubber and plastic insulation materials with polystyrene as the main raw material is relatively extensive at home and abroad, but most of them are in the field of plates, such as polystyrene board and steel wire mesh. Sandwich composite inner and outer wall panels, metal composite sandwich panels, etc. Although polystyrene board has good thermal insulation effect as rubber and plastic insulation material in use, due to the characteristics of the board, the polystyrene board is mainly fixed by point and fixed by surface when it is connected with the main body during construction. It is necessary to splicing and bonding, and it is not suitable for the insulation of buildings with complex shapes. The construction process is complicated and the comprehensive cost is high.
At the same time, because the hydrophobicity of the polystyrene board is not suitable for the conventional hydrophilic material, the subsequent construction quality outside the surface layer is not easy to ensure, and the quality problems such as cracking, falling off, and hollowing of the surface mortar are prone to occur on the building. Exterior decoration such as the use of bricks and coatings or construction constitutes a major constraint. The amorphous slurry rubber insulation material can overcome these shortcomings of the sheet metal, so it constitutes an important part of the building insulation material. Developed countries such as Europe and the United States started early in the research and application of slurry rubber and plastic insulation materials, and the technology is relatively mature, and has been effective in research and application.
In the research and development of rubber and plastic insulation material slurry, at present, the developed countries are mainly lightweight multi-functional composite slurry rubber and plastic insulation materials. The performance of such slurry rubber and plastic insulation materials is significantly improved compared with the traditional slurry rubber insulation materials, such as low thermal conductivity and good safety and durability. At the same time, this kind of composite slurry rubber and plastic insulation material has excellent functionality, such as non-French flame retardant polyurethane foam composite slurry rubber and plastic insulation material, ultra-light full-water calcium silicate slurry rubber insulation material. Etc., can meet the requirements of different use conditions.phenolic insulation manufacturers
The environmental protection issues of the rubber and plastic insulation materials industry are also highly valued abroad, and the development of “green” rubber and plastic insulation materials products, from raw material preparation (mining or transportation), product production and use, and future disposal issues, are required to maximize Save resources and reduce environmental damage. The rubber and plastic insulation material industry is a very successful example of the recycling of foreign resources.
In the modern exterior wall insulation decoration project, EPS, XPS, modified EPS are often bursting… These high-tech words are often dizzy for many users or laymen. Below, this article will explain to you. .thermal insulation material manufacturers
1.What is modified EPS (modified polystyrene board)
On the basis of traditional polystyrene board, DPX energy-saving technology has developed a new product through technology research and development: thermosetting grade A modified polystyrene board. The biggest feature is that the thermoplastic type of the traditional polystyrene board is upgraded to thermosetting. After fire detection, the fire performance reaches Class A. From the technical point of view, the thermosetting A-grade modified polystyrene board is divided into two types: coating type and permeability. The thermosetting A-grade coating type modified polystyrene board improves the polystyrene board from thermoplastic to thermosetting while maintaining the excellent physical properties of the polystyrene board, and effectively improves the fireproof performance of the polystyrene board, and can reach the grade A. At the same time, the properties of the thermal conductivity, compressive strength, water absorption, dimensional stability and the like of the polystyrene board are greatly improved by modification.
2.What is polystyrene board (EPS)?
Polystyrene board is called expandable polystyrene. In fact, it should not be fooled by such a tall name. It is usually called foam board or EPS board. Look at its true body EPS is a white solid with a fine closed cell structure, which is made of expandable polystyrene beads containing a volatile liquid foaming agent and heated and pre-formed in a mold. The traditional polystyrene board is low in cost and widely used in the fields of moisture proof, heat insulation, heat preservation, decoration, anti-collision, etc., and is widely used in exterior wall insulation. However, the fire performance is basically B grade, which deforms after water absorption, thus losing the heat preservation effect.
3.What is graphite polystyrene board
Its products are all called: graphite molded polystyrene foam board, referred to as SEPS board. It can be widely used in interior and exterior wall insulation systems. Compared with traditional products, graphite polystyrene board has stronger fire resistance, more stability and reliability, and greatly improves the thermal insulation performance of the product. The thermal conductivity of graphite polystyrene board is about 0.033, which is 0.008% lower than the commonly used expandable polystyrene (EPS), and the new standard flame retardant grade is B1. The graphite polystyrene board produced by DPX is also lower than the graphite polystyrene board. The flame retardant level of EPS. According to the current actual conditions and technical conditions, graphite polystyrene board is a safe exterior wall insulation material, which will become a powerful competitive material to replace polystyrene board in the near future.
Features of graphite polystyrene board 1. Graphite polystyrene board has good fireproof performance, and the combustion performance can reach the flame retardant B1 grade. 2. The heat insulation ability is stronger. It is a classic heat insulating material. The expanded polystyrene is further refined by chemical methods. The product has a thermal conductivity of ≤0.033, and its thermal insulation capacity is 30% higher than that of ordinary EPS, which can improve energy efficiency and reduce carbon dioxide emissions. 3, the same effect cost is lower, graphite polystyrene board cost-effective, with outstanding thermal insulation capacity, especially at low density, can be clearly expressed, in the same effect, it will be more cost-effective than other fire-resistant external insulation system .rock wool insulation suppliers 4. The construction is simple and the system integrity is good. The construction of the graphite polystyrene board external thermal insulation system is consistent with the construction method of the EPS thin plaster external wall thermal insulation system, and has high system integrity and durability. 5. Graphite polystyrene insulation board is mainly used for exterior wall insulation. The production process is to introduce graphite into the expandable polystyrene, so that it has the characteristics of good heat preservation effect and non-flammability.
