Description

Technical Field

[0001] The present invention belongs to the field of prefabricated building material production, and specifically relates to an ultra-low energy consumption composite insulation board, an insulation non-disassembly template and a manufacturing method. Background Art

[0002] Vacuum insulation panels are panels that have an insulation core material placed in an air-tight structure, vacuum-treated, and then sealed. Due to the internal vacuum characteristics, they have extremely low thermal conductivity and are used for exterior wall insulation, greatly improving the insulation effect. However, the barrier film on the outside of the vacuum insulation panel, which serves as the vacuum protective surface, is difficult to bond with cement, making the vacuum insulation panel easily damaged during construction and transportation, causing subsequent wall insulation layers to crack, hollow, and fall off. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention proposes an ultra-low energy consumption composite insulation board, an insulation non-disassembly template and a manufacturing method, which have stable bonding between a cement-based protective layer and a vacuum insulation layer and prevent cracking, hollowing and falling off of the wall insulation layer.

[0004] The present invention includes an ultra-low energy consumption composite thermal insulation board, including a cement-based maintenance layer and a vacuum insulation layer, wherein the cement-based maintenance layer is arranged on the outside of the vacuum insulation layer, and the vacuum insulation layer includes at least one vacuum insulation board, and the vacuum insulation board includes an insulation material as a core material and a plant fiber and membrane composite layer for vacuum sealing the insulation material. The vacuum insulation layer is located in the cement-based maintenance layer, and the cement-based maintenance layer is solid in texture. On the one hand, the vacuum insulation board can be protected from damage, and on the other hand, the plant fiber and membrane composite layer is used as a composite layer for coating the insulation material, and the inner side adopts a membrane layer, which can increase the strength and sealing performance of the plant fiber and membrane composite layer, and the outer side adopts a plant fiber layer, which can make the cement slurry with the coupling agent added react chemically with the plant fiber, and the two are connected and fixed into one body, so that the cement-based maintenance layer and the vacuum insulation layer become a solid whole, which solves the problem that the cement is directly used as the outer wall of the vacuum insulation board in the prior art, making it difficult to combine the cement-based maintenance layer and the vacuum insulation layer, resulting in cracking, hollowing, and falling off of the wall insulation layer.

[0005] In this embodiment, the vacuum insulation layer includes a vacuum insulation panel;

[0006] Or the vacuum insulation layer includes a vacuum insulation board, and at least one vacuum bag composed of a composite layer of plant fiber and film is set outside the vacuum insulation board, and then the vacuum bag is evacuated to form;

[0007] or the vacuum insulation layer comprises a plurality of vacuum insulation panels stacked together;

[0008] Or the vacuum insulation layer comprises a plurality of vacuum insulation panels stacked together, and at least one vacuum bag consisting of a composite layer of plant fiber and film is sheathed outside the overall structure formed by stacking the plurality of vacuum insulation panels, and then the vacuum bag is evacuated to form;

[0009] Or the vacuum insulation layer includes a plurality of vacuum insulation panels stacked together, and adjacent vacuum insulation panels are connected by cement slurry;

[0010] Or the vacuum insulation layer includes a plurality of vacuum insulation panels stacked together, adjacent vacuum insulation panels are connected by cement slurry, and at least one layer of vacuum bag composed of a composite layer of plant fiber and membrane is set outside the overall structure formed by stacking the plurality of vacuum insulation panels, and then the vacuum bag is evacuated to form.

[0011] The above-mentioned implementation mode includes a variety of implementation structures of the vacuum insulation layer composed of one or more vacuum insulation panels. Once the vacuum bag of the vacuum insulation panel is damaged, air will enter, and the vacuum bag and the rock wool board inside will be in a dispersed state, which will cause the wall insulation layer to crack, hollow and fall off. Therefore, on the one hand, the vacuum insulation panel is wrapped from the outside with a mesh cloth. Once the vacuum bag is damaged, the vacuum bag and the rock wool board inside are still tightly clamped together and will not fall apart, thereby preventing the wall insulation layer from cracking, hollowing and falling off. On the other hand, one or more layers of vacuum bags can be wrapped outside the vacuum insulation panel. In this way, even if the inner vacuum insulation panel is damaged, it is still protected by the vacuum bag on the outside, reducing the chance of cracking and hollowing of the wall insulation layer.

[0012] Furthermore, the cement-based maintenance layer includes a surface reinforcement layer respectively arranged on the upper and lower sides of the vacuum insulation layer, and the surface reinforcement layer is formed by coating or spraying cement slurry on the mesh cloth. The surface reinforcement layer is formed by coating cement slurry on the mesh cloth, which has high strength, is strong and durable, and plays a good protective role for the vacuum insulation panel. In addition, the surface reinforcement layer is thin in thickness and light in weight, and is suitable for energy-saving transformation of existing buildings.

[0013] Furthermore, the cement-based maintenance layer includes a surface reinforcement layer completely wrapped on the outside of the vacuum insulation layer, and the surface reinforcement layer is formed by wrapping a mesh cloth on the outside of the vacuum insulation layer, and applying or spraying cement slurry only on the mesh cloth on the upper and lower sides of the vacuum insulation layer or on all the mesh cloth wrapped on the outside of the vacuum insulation layer. In this way, the sides of the vacuum insulation panel are all covered with mesh cloth, and the surface reinforcement layer is formed by applying or spraying cement slurry, so that the cement-based maintenance layer is wrapped and combined with the surface reinforcement layer, thereby strengthening the protection of the vacuum insulation panel.

[0014] Furthermore, the cement-based maintenance layer includes an upper maintenance layer and a lower maintenance layer respectively arranged on the upper and lower sides of the vacuum insulation layer, the upper maintenance layer includes a cement-based thermal insulation layer and a surface reinforcement layer sequentially arranged on the vacuum insulation layer, the lower maintenance layer includes a cement-based thermal insulation layer and a surface reinforcement layer sequentially arranged on the vacuum insulation layer, or the lower maintenance layer only includes a surface reinforcement layer. One side of the vacuum insulation layer is a surface reinforcement layer, and the other side is a cement-based thermal insulation layer and a surface reinforcement layer. The vacuum insulation panel is close to the wall on one side, and only the cement-based surface reinforcement layer is set. In this way, while saving costs, it can also ensure that the wall and the present application are solidified into one, and the other side in contact with the outside world is set with a cement-based thermal insulation layer and a surface reinforcement layer, which is beneficial to protect the vacuum insulation panel, resist natural erosion, enhance weather resistance, and also improve the thermal insulation performance of the composite insulation panel.

[0015] The surface reinforcement layer is formed by coating or spraying cement slurry on the mesh cloth; the cement-based thermal insulation layer is made of cement-based thermal insulation slurry, and the cement-based thermal insulation slurry includes the following components: cement dry material, functionalized coupling agent, hydroxypropyl methylcellulose, rubber powder, rice husk, and nano-silicon expanded resin particles; 2 to 3 g of the functionalized coupling agent, 2 to 3 g of hydroxypropyl methylcellulose, 15 to 30 g of rubber powder, 60 to 80 g of rice husk, and 20 to 40 g of nano-silicon expanded resin particles are added to each kilogram of cement dry material; the functionalized coupling agent is selected from one of kH570 silane coupling agent and DL-411 aluminate coupling agent.

[0033] The present invention also includes a thermal insulation non-removal formwork, including a cement-based maintenance layer and a vacuum insulation layer, the cement-based maintenance layer is arranged on the outside of the vacuum insulation layer, the vacuum insulation layer includes a plurality of vacuum insulation panels laid flat in an array, the vacuum insulation panel includes an insulation material as a core material and a plant fiber and membrane composite layer that vacuum-seals the insulation material, there is a gap between adjacent vacuum insulation panels, and the gap is filled with cement-based insulation slurry. The above-mentioned thermal insulation non-removal formwork can be prefabricated in a factory, and insulation material is filled in the gap between adjacent vacuum insulation panels, which can improve the thermal insulation performance of the gap and avoid condensation of water vapor in the gap in cold seasons, causing problems such as mold on the wall. After being fixedly connected to the metal formwork frame on site, it is directly used as a formwork for wall casting, which not only ensures the stability of the connection between the wall and the ultra-low energy consumption composite insulation board, but also greatly improves the efficiency of construction.

[0035] The method for making the above-mentioned thermal insulation non-removal formwork comprises the following steps: applying cement slurry on a mesh cloth to form a lower surface reinforcement layer, then laying a vacuum insulation panel array on the lower surface reinforcement layer, laying the cement-based thermal insulation slurry on the vacuum insulation panel, and filling the gaps between adjacent vacuum insulation panels when laying the cement-based thermal insulation slurry, then laying a mesh cloth on the cement-based thermal insulation slurry and applying cement slurry on the mesh cloth, and naturally curing and drying to form a thermal insulation non-removal formwork;

[0036] In this embodiment, the cement-based maintenance layer includes an upper maintenance layer and a lower maintenance layer respectively arranged on the upper and lower sides of the vacuum insulation layer, and the upper maintenance layer and the lower maintenance layer are both surface reinforcement layers;

[0037] The method for making the above-mentioned thermal insulation non-removal formwork comprises the following steps: applying cement slurry on a mesh cloth to form a lower surface reinforcement layer, then laying a vacuum insulation panel array on the lower surface reinforcement layer, filling the cement-based thermal insulation slurry in the gaps between adjacent vacuum insulation panels, then laying a mesh cloth on the top surface of the vacuum insulation panel and applying cement slurry on the mesh cloth, naturally curing and drying to form the thermal insulation non-removal formwork.

[0040] Due to the adoption of the above scheme, the present invention has the following advantages:

[0041] 1. The vacuum insulation layer is located inside the cement-based maintenance layer. The cement-based maintenance layer is solid in texture. On the one hand, it can protect the vacuum insulation panel from damage. On the other hand, the plant fiber and membrane composite layer is used as a composite layer covering the thermal insulation material. The inner side adopts a membrane layer, which can improve the strength and sealing performance of the plant fiber and membrane composite layer, and ensure the protection of the thermal insulation material. The outer side adopts a plant fiber layer, so that the cement slurry with the coupling agent added reacts chemically with the plant fiber. The two are connected and fixed into one body, so that the cement-based maintenance layer and the vacuum insulation layer become a solid whole, which solves the problem in the prior art that cement and plastics and other materials used as the outer wall of the vacuum insulation panel are not bonded, so that the cement-based maintenance layer and the vacuum insulation layer are difficult to combine, resulting in cracking, hollowing, falling off of the wall insulation layer and other problems;

[0042] 2. The vacuum insulation layer of the present application may be composed of a single layer of vacuum insulation board or multiple layers of vacuum insulation board. Once the vacuum bag of the vacuum insulation board is damaged, air will enter, and the vacuum bag and the rock wool board inside will be in a dispersed state, which will cause the wall insulation layer to crack, hollow, and fall off. Therefore, on the one hand, the vacuum insulation board is wrapped from the outside with a mesh cloth or a wire mesh. Once the vacuum bag is damaged, the vacuum bag and the rock wool board inside are still tightly clamped together and will not fall apart, thereby preventing the wall insulation layer from cracking, hollowing, and falling off. On the other hand, one or more layers of vacuum bags can be wrapped outside the vacuum insulation board. In this way, even if the inner vacuum insulation board is damaged, the outer vacuum bag can still protect it, thereby reducing the probability of cracking and hollowing of the wall insulation layer.

[0043] 3. The membrane layer is a plastic layer or a plastic layer or a metal foil layer. The plastic layer or the plastic layer or the metal foil layer not only has good sealing performance but also has high strength;

[0044] 4. The cement-based maintenance layer is a surface reinforcement layer, which is formed by coating cement slurry on the mesh cloth. It has high strength, is strong and durable, and plays a good protective role for the vacuum insulation panel. In addition, the surface reinforcement layer is thin and light, and is particularly suitable for energy-saving renovation of existing buildings.

[0045] 5. The cement-based maintenance layer may also include a cement-based thermal insulation layer and a surface reinforcement layer sequentially arranged on the vacuum thermal insulation layer. The cement-based thermal insulation layer has thermal insulation function and high strength. Combined with the surface reinforcement layer, it strengthens the protection of the vacuum thermal insulation panel and also improves the overall thermal insulation effect of the composite thermal insulation panel.

[0046] 6. The present invention also includes a thermal insulation non-removal formwork, which is composed of a plurality of vacuum insulation panels laid in an array and a cement-based maintenance layer, wherein the cement-based maintenance layer on one side of the vacuum insulation panel is a surface reinforcement layer, and the other side can be separately set as a surface reinforcement layer, or can be a cement-based insulation layer and a surface reinforcement layer. When in use, the thermal insulation non-removal formwork is set with only one side of the surface reinforcement layer as the inner side of the formwork in direct contact with the concrete of the cast wall. Since the surface reinforcement layer and the wall are both cement-based materials, it is beneficial for the two to solidify into one. The other side of the thermal insulation non-removal formwork in contact with the outside world is beneficial to protecting the vacuum insulation panel, resisting natural erosion, and enhancing weather resistance. According to design requirements, the thermal insulation performance of the composite insulation board can be improved by adding a cement-based insulation layer.

[0047] In summary, the present invention forms an ultra-low energy consumption composite insulation board in which a vacuum insulation board is wrapped by a hard cement-based protective layer shell, solves the problem that the surface layer of the vacuum insulation board can be bonded to the cement-based material, and solves the defects of easy cracking, hollowing, and falling off when the vacuum insulation board is used for exterior wall insulation. The thermal conductivity of the ultra-low energy consumption composite insulation board is only equivalent to 1 / 5-1 / 10 of existing insulation materials such as extruded boards and polystyrene boards, and the thermal insulation performance is excellent.

DETAILED DESCRIPTION

[0069] The present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention. In addition, those skilled in the art can make corresponding combinations of the features in the embodiments and in different embodiments in this document based on the description of this document.

[0070] like Figure 1 As shown, an ultra-low energy consumption composite insulation board comprises a cement-based maintenance layer 2 and a vacuum insulation layer 1, wherein the cement-based maintenance layer 2 is arranged on the outer side of the vacuum insulation layer 1, and the vacuum insulation layer 1 comprises at least one vacuum insulation panel 11, as shown in FIG. Figure 2 The vacuum insulation panel 11 is formed by placing the heat-insulating material into a vacuum bag made of the plant fiber and film composite layer 12 and vacuum-sealing it. In this embodiment, the plant fiber and film composite layer 12 includes an outer plant fiber layer 121 and an inner film layer 122, and the film layer 122 is a plastic layer or a plastic layer or a metal foil layer. When the plant fiber layer 121 is a paper layer, the plant fiber and film composite layer 12 is a paper film composite layer;

[0071] Furthermore, the thermal insulation material in the vacuum insulation panel 11 is a thermal insulation board composed of a single-layer glass fiber board or a single-layer rock wool board;

[0072] Or it is a thermal insulation board composed of multiple layers of glass fiber boards, with an aerogel surface layer provided between adjacent glass fiber boards;

[0073] Or it is an insulation board composed of multiple layers of rock wool boards, with an aerogel surface layer provided between adjacent rock wool boards;

[0074] Or it is an insulation board made of nano silicon powder and fiber, which comprises the following components by mass percentage: 97-99% of nano silicon powder and 1-3% of fiber, wherein the fiber is PP fiber or alkali-resistant glass fiber.

[0075] With the above structure, since the inner plastic layer or plastic layer or metal foil layer has excellent sealing performance and high strength, it can well protect the internal insulation material. The outer side uses the plant fiber layer 121 because the plant fiber layer 121 can react chemically with the cement slurry 24 with the coupling agent added, so that the two are fixed into one. This solves the problem in the prior art that cement and plastic, plastic and other materials used as the outer wall of the vacuum insulation panel 11 are not bonded, making it difficult to combine the cement-based maintenance layer 2 with the vacuum insulation layer 1, resulting in cracking, hollowing, falling off and other problems in the wall insulation layer.

[0076] like Figures 3 to 15 As shown, several embodiments of the ultra-low energy consumption composite insulation board of the present invention are listed here, but the protection scope of the present invention should not be limited to the following embodiments:

[0077] Embodiment 1:

[0078] like Figure 3 As shown, in this embodiment, the vacuum insulation layer 1 constituting the ultra-low energy consumption composite insulation board includes a vacuum insulation board 11; the cement-based maintenance layer includes a surface reinforcement layer respectively arranged on the upper and lower side surfaces of the vacuum insulation layer, and the surface reinforcement layer is formed by coating or spraying cement slurry on the mesh cloth, and the cement slurry includes the following components: cement dry material, functionalized coupling agent, hydroxypropyl methylcellulose, and rubber powder; 2 to 3 g of the functionalized coupling agent, 1 to 2 g of hydroxypropyl methylcellulose, and 15 to 30 g of rubber powder are added to each kilogram of cement dry material, and the functionalized coupling agent is selected from one of kH570 silane coupling agent and DL-411 aluminate coupling agent.

[0079] Embodiment 2:

[0080] like Figure 4As shown, the difference between this embodiment and embodiment 1 is that the surface reinforcement layer is formed by wrapping a mesh cloth on the outside of the vacuum insulation layer, and coating or spraying cement slurry on the entire mesh cloth wrapped outside the vacuum insulation layer.

[0081] Embodiment 3:

[0082] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that the structures of the vacuum insulation layers 1 of the two are different. In this embodiment, the vacuum insulation layer 1 is a vacuum bag 25 composed of a composite layer of plant fiber and membrane, which is enclosed on the outside of the vacuum insulation panel 11 and then formed by evacuating the vacuum bag 25.

[0083] Embodiment 4:

[0084] like Figure 6 As shown, the difference between this embodiment and embodiment 2 is that the structures of the vacuum insulation layers 1 of the two are different. In this embodiment, the vacuum insulation layer 1 is a vacuum bag 25 composed of a composite layer of plant fiber and membrane, which is sheathed on the outside of the vacuum insulation panel 11, and then the vacuum bag 25 is evacuated to form.

[0085] Embodiment 5:

[0086] like Figure 7 As shown, the difference between this embodiment and embodiment 1 is that the structures of the cement-based maintenance layers of the two are different. In this embodiment, the cement-based maintenance layer includes an upper maintenance layer and a lower maintenance layer respectively arranged on the upper and lower sides of the vacuum insulation panel 11, and the upper maintenance layer and the lower maintenance layer both include a cement-based thermal insulation layer 21 and a surface reinforcement layer 22 sequentially arranged on the vacuum insulation layer. The two sides of the vacuum insulation panel 11 are provided with a cement-based thermal insulation layer 21 and a surface reinforcement layer 22. The cement-based thermal insulation layer 21 has a thermal insulation function and high strength. It is combined with the surface reinforcement layer 22 to strengthen the protection of the vacuum insulation panel 11, and also improve the overall thermal insulation effect of the composite thermal insulation panel.

[0087] In addition, in this embodiment, the cement slurry constituting the surface enhancement layer is in direct contact with the cement-based thermal insulation layer 21, and not in direct contact with the vacuum insulation layer.

[0098] Embodiment 11:

[0099] like Fig.13 As shown, in this embodiment, the vacuum insulation layer 1 constituting the ultra-low energy consumption composite insulation board includes two vacuum insulation panels 11 stacked together, and the two vacuum insulation panels 11 are in direct contact with each other; the cement-based maintenance layer includes a surface reinforcement layer 22 completely wrapped on the outside of the vacuum insulation layer, and the surface reinforcement layer 22 is formed by wrapping a mesh cloth on the outside of the vacuum insulation layer, and applying or spraying cement slurry on all the mesh cloth wrapped on the outside of the vacuum insulation layer. The above-mentioned cement slurry includes the following components: cement dry material, functionalized coupling agent, hydroxypropyl methylcellulose, and rubber powder; 2-3g of the functionalized coupling agent, 1-2g of hydroxypropyl methylcellulose, and 15-30g of rubber powder are added to each kilogram of cement dry material, and the functionalized coupling agent is selected from one of kH570 silane coupling agent and DL-411 aluminate coupling agent.

[0100] Embodiment 12:

[0101] like Fig.14 As shown, in this embodiment, the vacuum insulation layer 1 constituting the ultra-low energy consumption composite insulation board includes two vacuum insulation panels 11 stacked together, and the two vacuum insulation panels 11 are in direct contact with each other; the vacuum insulation layer 1 is formed by a vacuum bag 25 composed of a composite layer of plant fiber and film, which is set on the outside of the overall structure formed by stacking multiple vacuum insulation panels 11, and then the vacuum bag 25 is evacuated to form, and the cement-based maintenance layer includes a surface reinforcement layer respectively arranged on the upper and lower side surfaces of the vacuum insulation layer, and the surface reinforcement layer is formed by scraping or spraying cement slurry on the mesh cloth, and the above-mentioned cement slurry includes the following components: cement dry material, functionalized coupling agent, hydroxypropyl methylcellulose, and rubber powder; 2-3g of the functionalized coupling agent, 1-2g of hydroxypropyl methylcellulose, and 15-30g of rubber powder are added to each kilogram of cement dry material, and the functionalized coupling agent is selected from one of kH570 silane coupling agent and DL-411 aluminate coupling agent.

[0102] Embodiment 13:

[0103] like Fig.15 As shown, the difference between this embodiment and embodiment 12 is that the structures of the surface reinforcement layers of the two are different. In this embodiment, the surface reinforcement layer is composed of a mesh cloth wrapped around the outside of the vacuum insulation layer, and cement slurry is scraped or sprayed on the entire mesh cloth wrapped outside the vacuum insulation layer.

[0104] In the above embodiment, the surface reinforcement layer 22 is formed by coating cement slurry 24 on the mesh cloth, which has high strength, is strong and durable, and plays a good protective role on the vacuum insulation panel 11. The mesh cloth can be an alkali-resistant glass fiber mesh cloth; and the surface reinforcement layer 22 is thin and light, and is particularly suitable for energy-saving renovation of existing buildings. At the same time, the mesh cloth can improve the performance of the vacuum insulation panel 11 and prevent expansion and cracking; the cement-based thermal insulation layer is formed by mixing the cement-based thermal insulation slurry evenly;

[0105] Multiple stacked vacuum insulation panels 11 are placed in a vacuum bag composed of a plant fiber and film composite layer 12, and then a mesh cloth is wrapped on the outside of the vacuum bag; with the above structure, multiple layers of vacuum insulation panels 11 are stacked and fixed together to form a whole, which improves the heat preservation and heat insulation effect, and the heat preservation effect can also be guaranteed. If one vacuum insulation panel 11 is damaged, the other vacuum insulation panel 11 can continue to play the heat preservation and heat insulation function. In addition, the stacked vacuum insulation panels 11 are wrapped together by the mesh cloth, and the insulation material will not spread out, so that the insulation layer can be intact.

[0106] Once the vacuum bag of the vacuum insulation panel 11 is damaged, air will enter, and the vacuum bag and the rock wool board inside will be in a dispersed state, which will cause the wall insulation layer to crack, hollow, and fall off. Therefore, on the one hand, the vacuum insulation panel 11 is wrapped from the outside with a mesh cloth or a wire mesh. Once the vacuum bag is damaged, the vacuum bag and the rock wool board inside are still tightly clamped together and will not fall apart, thereby preventing the wall insulation layer from cracking, hollowing, and falling off. On the other hand, one or more layers of vacuum bags can be wrapped around the outside of the vacuum insulation panel 11. In this way, even if the inner vacuum insulation panel 11 is damaged, it is still protected by the vacuum bag on the outside, thereby reducing the chance of cracking and hollowing of the wall insulation layer.

[0107] According to the above-mentioned embodiments 1 to 13, the present invention also includes three methods for making ultra-low energy consumption composite insulation boards. Three forms are listed here, but the patent scope of the present invention is not limited thereby:

[0109] The second manufacturing method comprises the following steps: directly applying or spraying cement slurry only on the mesh cloths on the upper and lower sides of the vacuum insulation layer or on all the mesh cloths wrapped outside the vacuum insulation layer to form a surface reinforcement layer, and then naturally curing and drying to make an ultra-low energy consumption composite insulation board; the cement slurry comprises the following components: cement dry material, functionalized coupling agent, hydroxypropyl methylcellulose, and rubber powder; 2 to 3 g of the functionalized coupling agent, 1 to 2 g of hydroxypropyl methylcellulose, and 15 to 30 g of rubber powder are added to each kilogram of cement dry material, and the functionalized coupling agent is selected from one of kH570 silane coupling agent and DL-411 aluminate coupling agent.

[0113] The functionalized coupling agent uses kH570 silane coupling agent, and the silane alkoxy group is reactive to inorganic substances, and the organic functional group is reactive or compatible to organic substances. Therefore, when the silane coupling agent is between the inorganic and organic interfaces, a bonding layer of an organic matrix-silane coupling agent-inorganic matrix can be formed. The inorganic and organic substances are fixed into one. Therefore, water and silane coupling agent are added to cement, and stirred evenly to carry out a chemical reaction, and a bonding layer of an organic matrix-coupling agent-inorganic matrix is ​​formed between the cement-based maintenance layer 2 and the outer wall of the vacuum insulation panel 11, thereby firmly fixing the cement-based maintenance layer 2 and the vacuum insulation panel 11 together.

At the same time, 40-60% of the hydroxyethyl cellulose and tricalcium phosphate proportions determined in the first step are added, and the temperature is raised to 85-95° C. for constant temperature polymerization reaction. After the reaction for 3-4 hours, 20-30% of the hydroxyethyl cellulose and tricalcium phosphate proportions determined in the first step are added to the reactor, and the constant temperature reaction is continued for 3-4 hours. Finally, add hydroxyethyl cellulose determined in the first step, 20-30% of tricalcium phosphate and pentane to the reactor, control the pressure in the reactor to be ≤1.0Mpa, heat to 115-130°C, maintain for 3-4h, cool to below 30-50°C and discharge, dehydrate and dry the material and stir it in a powder coating agent for 1-4 minutes to obtain nano-silicon expanded resin particles; the coating agent includes the following components by mass percentage: monoglyceride 9-11%, diglyceride 18-22%, and zinc stearate 68-72%.
