Detailed Description

As shown in fig. 1, a composite thermal insulation wall is characterized in that: the plates are symmetrically arranged, and the middle layer 1, the rock wool layer 2 and the calcium silicate plate layer 3 are sequentially made of materials from the middle to the outside. The symmetrical arrangement, simple to operate need not distinguish the positive and negative. The rock wool layer 2 can use the rock wool of compression to increase the heat preservation effect, for example with 75 centimetres thickness rock wool compression for 8 centimetres, also can adjust the compression thickness according to cost requirement and actual need. Calcium silicate boards (English: calcium silicate) as novel green and environment-friendly building materials have the advantages of excellent fire resistance, moisture resistance and super-long service life besides the functions of traditional gypsum boards, and are widely applied to suspended ceilings and partition walls of industrial and commercial engineering buildings, home decorations, liner plates of furniture, liner plates of billboards, shed plates of warehouses, network floors, wall plates of tunnels and other indoor engineering. The product is fireproof, moistureproof, soundproof, mothproof and durable, and is an ideal decorative plate for suspended ceilings and partitions. The rock wool heat insulation board is prepared by melting basalt and other natural ores as main raw materials, adopting an international advanced four-roller centrifugal cotton manufacturing process to spin and draw a high-temperature solution of the basalt into discontinuous fibers with the diameter of 4-7 mu m, adding a certain amount of binder, dustproof oil and water repellent into the rock wool fibers, settling, curing, cutting and the like, and preparing series products with different densities according to different purposes. The rock wool heat-insulating board product is suitable for heat insulation, sound insulation and the like of industrial equipment, buildings and ships. The rock wool board has a low coefficient of thermal conductivity. The heat conductivity coefficient is an important index for measuring the quality of the rock wool board, and the smaller the heat conductivity coefficient is, the less energy is transferred through the material, and the better the heat insulation performance of the heat insulation rock wool board is. Have higher acoustic absorption coefficient, the sound absorption effect of heat preservation rock wool board mainly depends on the density of rock wool board in unit area, and density is big more, and the sound absorption effect is better. Good rock wool panels should have low moisture absorption, and after most insulation materials absorb water, the insulation effect is significantly reduced because of the high thermal conductivity of water.

Further, as shown in fig. 2, the intermediate layer 1 is a foam particle 11 fixed together and an inorganic cement 12 covering the fixed foam particle. The inorganic adhesive is a novel adhesive, can resist high temperature and low temperature, has low cost, is not easy to age, and has simple structure and high adhesion. The inorganic adhesive has high temperature resistance and low temperature resistance, can bear the temperature of about 1000 ℃ or higher, and can resist the high temperature of 1800 ℃ through the improved inorganic adhesive. The inorganic adhesive is generally water-soluble, has low toxicity, does not burn and causes no environmental pollution. The thermal expansion coefficient is only 1/10 of steel and 1/3 of ceramic. Oil resistance, radiation resistance, no aging and good durability. The inorganic adhesive is not resistant to acid and alkali corrosion, has poor water resistance, high brittleness and impact resistance. The inorganic adhesive can be cured at room temperature, basically does not shrink, and slightly expands in some cases. The inorganic adhesive has high bonding strength of socket joint and groove joint, is not suitable for flat joint, and has the socket joint tensile shear strength of more than 100 MPa. Inorganic gums are mostly pastes of solids mixed with liquids. The raw materials are easy to obtain, the price is low, and the use is convenient.

Further, the foam particles 11 are one of polyurethane foam particles, phenolic foam particles, polyvinyl chloride foam particles and polystyrene foam particles. The foam particles 11 are cheap, have certain heat insulation effect and low density, and can reduce the weight of the whole wall. The foam particles 11 are relatively inexpensive and have a low density. Polyvinyl chloride foam is a foam which is used earlier, and is produced by using a polyvinyl chloride resin as a main body and adding a foaming agent and other additives. They are classified into hard and soft types, and the soft type is more common. It has good mechanical properties and impact absorption; is a closed-pore type soft bubble body; the density of the material is between 0.05 and 0.1g/cm 3; the chemical property is stable, and the corrosion resistance is strong; it is non-absorbent, non-inflammable and cheap. As shown in fig. 2, the preferred inorganic binder 12 is mixed with the intermediate layer 1 of the foam particles 11 in a proportion based on the flame retardant effect, and the proportion may be changed as required within the standard. The foam particles 11 can be selected from polyurethane foam particles, phenolic foam particles, polyvinyl chloride foam particles, polystyrene foam particles, and the like organic foam particles 11. The inorganic cementing agent 12 is provided for preventing the foam particles 11 from burning, and the inorganic cementing agent 12 is coated on the outer layer of the foam particles 11 to isolate the combustion supporter to prevent the foam particles 11 from burning. The preferred inorganic adhesive 12 is cement or gypsum. The material of the foam particles 11 may be selected appropriately according to cost, heat insulating effect, density, sound insulating effect, heat resistance, corrosion resistance, and the like. Since the cement or gypsum coats the foam particles 11, the foam particles 11 are prevented from burning, and belong to flame retardant materials. Figure 2 is a schematic diagram only for showing how the inorganic cement 12 coats the foam particles 11, and does not limit the shapes and proportions of the foam particles 11 and the inorganic cement 12.

Further, the thickness of the middle layer 1 of the inorganic cementing agent and the foam particles is 1.5cm, the thickness of the rock wool layer 2 is 8cm, and the thickness of the calcium silicate board layer 3 is 5 mm. Therefore, the overall thickness is about 10cm, and the light steel framework house is suitable for maintenance structures of light steel framework houses. The thickness of the whole composite heat-insulating wall body and each layer can be adjusted according to the thickness or the width of a steel frame used as a support keel, so that the whole composite heat-insulating wall body is consistent during installation and has no convex part.

Further, the outer layer 3 of the calcium silicate board is provided with a decorative layer 4. The decorative layer 4 is preferably a putty powder layer. The decorative layer 4 may also be a combination of putty powder and latex paint. The decorative layer 4 serves to decorate the surface of the wall. The envelope structure can be well beautified through the decorative layer 4, the calcium silicate board is a common household decorative material, and compared with a color steel plate, the calcium silicate board is more permanent and more household-friendly. The decorative layer 4 can also be designed with certain patterns to represent various originality, and the decorative layer 4 can represent different patterns by using different materials, different colors and different patterns.

Different materials have different physical and chemical properties, and the physical and chemical properties of the same material with different qualities can also be different. The thickness of the preferable composite heat-insulating wall body is 10cm, and the whole thickness and the thickness of each layer can be adjusted according to requirements. For example, a layer with low thermal conductivity can be thicker to achieve better thermal insulation, or a layer with low density can be thicker to reduce the overall weight. The design can be carried out according to the Fourier heat conduction law to achieve a certain heat preservation effect.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
