What are the exterior thermal insulation materials? Did you make it? Zero

More and more attention has been paid to the development and application of thermal insulation materials for building exterior wall. Foreign attention has been paid to the production of thermal insulation materials and its application in construction, so as to reduce energy consumption greatly, thus reducing environmental pollution and greenhouse effect. Foreign insulation materials industry has a long history, the building energy saving thermal insulation materials accounted for the vast majority, and new thermal insulation materials are also emerging. What are the exterior walls from thermal insulation materials? Let’s take a look at it.

What are the exterior thermal insulation materials?

Polyurethane material is the best thermal insulation material in the world. Rigid polyurethane has many excellent properties. It is widely used in building roofs, walls, ceilings, floors, doors and windows as insulation materials in Europe and america. In Europe and America and other developed countries, about 49% of building thermal insulation materials are polyurethane materials, while in China this ratio is less than 10%. Therefore, there is still a lot of room for the development of polyurethane materials in china.

China’s energy-saving building materials market is larger, especially building insulation materials. The energy loss of China’s residential buildings is roughly 50% of that of the wall, about 10% of the roof, about 25% of the doors and windows, and about 15% of the basement and the ground. China’s construction in 2010 to achieve energy-saving rate of 50%, the need for a comprehensive renovation of the building walls, wall insulation materials market will increase substantially.

1. Silicate insulation material

Silicate insulation material is a kind of net structure material with solid matrix and closed pore opening. This product is a special non-metallic mineral containing aluminum, magnesium and silicate as the base material. A certain amount of auxiliary raw materials and fillers are added, and certain chemical additives are added.

2. Ceramic thermal insulation material

Ceramic insulation board with clay tailings, ceramic pieces, river silt, adulterated materials as the main raw material, calcination and production process using advanced technology and foamed high porosity closed cell ceramic materials. The product is suitable for building exterior wall insulation, fire, building insulation and cold bridges etc..

3. Rubber powder polyphenyl granule

EPG powder polystyrene particles insulation system is the main cementing material to dry mix mortar mixed with polypropylene fiber, and a variety of appropriate additives, with polystyrene foam particles as lightweight aggregate, according to the proportion, stir evenly in the field, both internal and external surface of exterior use, convenient construction, and good insulation effect.

5 、 extrusion plate XPS

The system adopts XPS polystyrene Extrusion board (hereinafter referred to as Extrusion board) as the exterior wall insulation material of building. When the main building and exterior wall masonry project is finished, XPS special interface agent is applied on the bottom mortar. Will nap XPS extruded polystyrene board by bonding mortar paste according to the requirements on the wall, and the use of plastic expansion screws to anchorage. Then apply the polymer cement mortar in extruded plate surface, which is pressed into the alkali coated glass fiber grid cloth strengthen anti crack mortar protection layer, the putty and paint decorative surface layer (such as a decorative surface layer of ceramic tile, you should use the galvanized steel wire net and special ceramic tile adhesives and grouts).

6 、 hard foam polyurethane on-site spraying

The isocyanate, polyol two component liquid raw materials, using fluorine free foaming technology, thermal reaction in a certain condition, generation rate of obturator ≥ 95% (≥ 92%) the rigid foam compound — — waterproof and thermal insulation integrated materials of rigid polyurethane foam (PUR).

7, HD-STP insulation materials

HD-STP building exterior vacuum insulation system is a new and efficient insulation material, and also the best thermal insulation material at present. It is based on the principle of vacuum insulation, through the maximum increase in the degree of vacuum and filled with core insulation material to achieve efficient insulation.

8. Spray polyurethane rigid foam

Rigid polyurethane foam with isocyanate and polyether as the main raw material, the foaming agent, catalyst and flame retardant additives under the action of special equipment by mixing polymer by high pressure spraying foam into. Polyurethane foam is a kind of new synthetic insulation materials and waterproof function, its low thermal conductivity is only 0.022 ~ 0.024W\/ (M? Κ), equivalent to half of the board, is the thermal conductivity of thermal insulation material in the lowest of all.

9, NJ-STP insulation board

STP ultra-thin vacuum insulation board is inorganic fiber core material and high barrier vacuum composite membrane, through super vacuum treatment of a fire retardant, super book, efficient vacuum insulation material. STP insulation board is mainly made of inorganic fiber core material and high barrier composite membrane. It is made by super vacuum treatment and scientific packaging technology. High barrier composite film: inorganic fiber cloth, aluminum foil and multilayer dense material compound and into, it undertakes the STP plate protection and fixed function, has a direct impact on the quality of life of barrier film on insulating sheet.
