DETAILED DESCRIPTION
[0024] The principles and characteristics of the present application are described below in combination with all the drawings, and the examples are only used to explain the present application, and are not used to limit the scope of the present application.
[0025] In recent years, the thermal insulation and decoration integrated system is used more in public buildings and low-rise residential buildings, and the thermal insulation decorative plate is the core material of the system. The decorative materials of the thermal insulation decorative plate on the market generally use marble, ceramic thin plate, silica calcium plate (real stone paint, fluorocarbon paint, imitation stone paint, etc.) as decoration, mainly use polystyrene plate (EPS, XPS), polyurethane plate, etc. as thermal insulation materials. They are compounded together through self-adhesion or adhesive.
[0026] Reference Figure 1 The thermal insulation decorative plate generally comprises a facing layer 1, an adhesive layer 2 and a thermal insulation layer 3. The thermal insulation decorative composite plate is produced by a self-adhesion process. Although the production efficiency is high, the facing layer 1 and the thermal insulation plate are directly compounded in the production process of the thermal insulation layer 3. The stress between the two materials is not released. After the thermal insulation decorative plate is naturally stabilized, the plane of the plate will be warped and deformed, which seriously affects the construction.
[0027] The main adhesives used in the adhesive process are cement mortar or polymer cement mortar and organic adhesive. The cement-based adhesive composite has low production efficiency and generally needs more than 8-12 hours to solidify. The bonding layer has a thickness of more than 6 mm, which not only increases the apparent thickness of the thermal insulation composite plate but also greatly increases the weight of the thermal insulation decorative plate. The construction accessories must be selected with higher specifications. The construction process cost is increased, and the safety and stability after being installed on the wall are not good. The currently used organic adhesive has high price, large viscosity, large amount of use, and can only be coated by rolling or scraping. The solidification time is long, generally 4-6 hours, the production efficiency is low, and the cost is high.
[0028] The thermal insulation decorative plate compounded together is placed horizontally, the facing layer 1 is on the top, and the thermal insulation layer 3 is on the bottom. From top to bottom, they are the facing layer 1, the adhesive layer 2 and the thermal insulation layer 3. The facing layer 1 can be marble, ceramic sheet, different painted silicon calcium plate, etc. The adhesive layer 2 can be cement-based adhesive, polymer cement-based adhesive, single or double component polyurethane adhesive (the polyurethane adhesive on the market is non-foaming and is a prepolymer type adhesive, that is, all or part of the isocyanate is first reacted with part or all of the polyether polyol at a certain temperature for several to ten hours, and then dehydrated, reacted, and added fillers), dolomite glue and other resin glue. The thermal insulation layer 3 can be polyurethane plate or polystyrene plate. The main production process is to use pressurized compounding.
[0029] At present, there are many defects in the production process of thermal insulation decorative plate on the market. The production process is complex and the production efficiency is low. In the prior art, the general method is to use glue, pressurized curing machine, and generally it takes more than 4 hours to press the composite plate. The production process of the thermal insulation layer 3 is easy to slide and deviate. The production stress between the decorative layer 1 and the thermal insulation layer 3 is not released in the self-adhesive process of the thermal insulation decorative composite plate. After the thermal insulation decorative plate is naturally stable, the plane of the plate will be warped and deformed, which will seriously affect the construction. The cement-based adhesive composite of the adhesive process has complex coating process, low production efficiency and long curing time. The bonding layer is thick, which increases the thickness and weight of the thermal insulation composite plate, and the construction cost is high. After being installed on the wall, the safety and stability are not good. The currently used organic adhesive has complex manufacturing process and is prepared through complex chemical reaction. The cost is high, the viscosity is large, the amount is large, the coating process is complex, the curing time is long, and the production efficiency is low. There is no foaming function. During the curing process, only the surface of the bonding interface is cured, and the penetration effect is limited. In the long-term use, the thermal insulation layer 3 and the decorative layer 1 have the risk of separation.
[0030] The utility model discloses a kind of thermal insulation decorative plates.
[0031] Referring to Figure 1 A kind of thermal insulation decorative plate, including decorative layer 1, adhesive layer 2 and thermal insulation layer 3, decorative layer 1, adhesive layer 2 and thermal insulation layer 3 are sequentially stacked from top to bottom. Thermal insulation layer 3 is selected from one or several of polystyrene insulation board, rigid polyurethane insulation board, foamed ceramic plate, vertical silk rock wool strip or vertical silk rock wool composite board. Vertical silk rock wool strip is the thermal insulation board with one side composite organic polymer sheet. Vertical silk rock wool composite board refers to the thermal insulation board with vertical silk rock wool double-sided composite organic polymer sheet.
[0032] Referring to Figure 1 And Figure 2 Decorative layer 1 is provided with fastening groove one 11 on the side close to adhesive layer 2, fastening groove one 11 penetrates one side of decorative layer 1, thermal insulation layer 3 is provided with fastening groove two 31 on the side close to adhesive layer 2, fastening groove two 31 penetrates one side of thermal insulation layer 3, fastening groove one 11 and fastening groove two 31 are corresponding to each other in position, fastening strip 4 is arranged in fastening groove one 11 and fastening groove two 31, and fastening strip 4 penetrates adhesive layer 2. The cross section of fastening strip 4 is in the shape of "8", and the shape and size of fastening strip 4 are matched with the shape and size of the combination of fastening groove one 11 and fastening groove two 31.

The problem of complex production process and low production efficiency is solved. The production mode of pressure curing composite commonly used in the prior art is abandoned, the structure of the fastening strip 4 is adopted, and direct composite and direct stacking are adopted.

The problems of the prior art, such as void, hollowing and delamination of the adhesive layer 2, are also solved. In the long-term use process, the problems of aging of the adhesive layer 2 and separation of the veneer layer 1 and the thermal insulation layer 3 are solved.
[0035] Referring to Figure 1 , by using the fastening strip 4, the anti-falling disc 5 and the adhesive multiple connection composite mode, the pressing composite mode commonly used in the prior art is abandoned in the production process.

No special equipment is needed for pressing. Unlike the prior art, the adhesive does not need to be cured before it can be taken out of the press. It can be directly stacked, greatly improving the production efficiency and reducing the production cost. Through the design of the fastening strip 4, the problems of complex production process and low production efficiency in the prior art are solved. The production mode of pressure curing composite commonly used in the prior art is abandoned. Direct composite and direct stacking are adopted. The production efficiency of the thermal insulation decorative board is improved, and the stability of the thermal insulation decorative board is also improved, which ensures normal construction.

[0037] Due to the use of the fastening strip 4, the facing layer 1 and the thermal insulation layer 3 are equivalent to being interlocked with each other during the compounding process, so that the sliding deviation phenomenon of the thermal insulation layer 3 in the prior art is avoided, and even if the adhesive is damaged during long-term use, the phenomenon that the facing layer 1 and the thermal insulation layer 3 are separated is not generated.
