Building exterior wall thermal insulation materials development and application of more and more universal attention of all countries in the world. Foreign countries generally attach importance to the production of insulation materials and their application in construction, and strive to drastically reduce energy consumption so as to reduce environmental pollution and greenhouse effect. Foreign insulation materials industry has a long history, energy-saving building thermal insulation with the vast majority of insulation materials, and new insulation materials are also constantly emerging. What external wall thermal insulation material?
1, Aerogel insulation material
Aerogel insulation is the best insulating material in the world. Aerogel insulation material has many excellent properties, widely used in Europe and the United States for building roofs, walls, ceilings, floors, doors and windows as a thermal insulation material. About 49% of building insulation materials in developed countries such as Europe and the United States are aerogel insulation materials, while in China, the proportion is less than 1%. Therefore, aerogel insulation materials in China there is still much room for development.
2, Silicate insulation materials
Silicate insulation material is a kind of closed-cell mesh material with solid matrix connection. This product is a kind of special nonmetallic ore containing aluminum, magnesium and silicate as the base material, mixed with a certain amount of auxiliary raw materials and Filling materials add certain chemical additives, to adopt new technology, new technology developed.
3, Ceramic insulation materials
Ceramic insulation board is a clay material tailings, ceramic chips, river sludge, adulterated material as the main raw material, the use of advanced production technology and foam technology by high temperature roasted high porosity closed-cell ceramic materials. Products are suitable for building exterior wall thermal insulation, fire isolation zone, building self-insulation cold and heat bridge treatment.
4, Powder polystyrene particles
EPG powder polystyrene insulation system is based on premixed dry mix mortar as the main cementitious material, adding appropriate cracking fiber and a variety of additives to polystyrene foam particles as light aggregate, the proportion of configuration, at the scene Stir well, the exterior and interior surfaces of the exterior walls are used, easy to construct, and the insulation effect is better.
5, Extrusion board XPS
The system is using XPS polystyrene extruded board (hereinafter referred to as extruded board) as the building's exterior wall thermal insulation materials, when the main building and exterior masonry work is completed, the bottom of the mortar brushing XPS interface agent. The XPS extruded polystyrene board with adhesive mortar paste on the wall as required, and use plastic expansion screws to be anchored. Then squeeze the surface of the extruded polymer cement mortar, which pressed into the alkali-resistant plastic coated fiberglass reinforced cracking mortar protective layer, and finally putty and decorative coatings (such as the decorative surface of the tile should be Switch to galvanized steel mesh and special tile adhesives and grouts).
6, Hard foam polyurethane spray on site
Adopting isocyanates and polyhydric alcohol as raw material of two components, using fluorine-free foaming technology, thermal reaction occurs under certain conditions to produce rigid foam compound with closed cell ratio ≥95% (or ≥92%) - polyurethane rigid foam Body waterproof thermal insulation integrated materials (PUR).
7, HD-STP insulation materials
HD-STP exterior wall ultra-thin vacuum insulation board insulation system is a new type of highly efficient wall thermal insulation materials, thermal insulation material is the best insulation material. It is based on the principle of vacuum insulation and achieves efficient thermal insulation by maximizing the vacuum in the panel and filling it with core insulation.
8,Spray polyurethane foam
Polyurethane rigid foam is based on isocyanate and polyether as the main raw material, in the foaming agent, catalyst, flame retardant and other additives under the action of mixing through special equipment, high-pressure spray on-site foam polymer Things. Polyurethane foam is a new type of synthetic material with thermal insulation and waterproof function. Its thermal conductivity is low, only 0.022 ~ 0.024W / (m? K), which is equivalent to half of the extruded board. It is the current thermal conductivity of all thermal insulation materials lowest.
9, NJ-STP insulation board
STP thin vacuum insulation board is a Class A fireproof, super-book, high-efficiency, vacuum insulation material with super-vacuum treated inorganic fiber core and high barrier vacuum composite membrane. STP insulation board is mainly inorganic fiber core and high barrier composite membrane through the super-vacuum treatment, science and technology package made. High barrier composite membrane: inorganic fiber cloth, aluminum foil and multi-layer compact material composite, which bear the protective and fixed role of STP sheet periphery, the quality of the barrier film has a direct impact on the life of wall thermal insulation sheet.
