The color steel sandwich panel is prepared by firstly mixing white latex, silica sol and an organic silicon resin adhesive, uniformly stirring to obtain a composite high-temperature adhesive, then uniformly coating the composite high-temperature adhesive on the surface of a color steel plate, and then covering the prepared flame-retardant XPS plate on the surface of the color steel adhesive for 10 minutes under the pressure of 12 kilograms. The method has the main problems that the compressive strength of the prepared color steel sandwich board is not good enough, the bonding force between the core material and the color steel board is not strong enough, the combustion performance of the color steel board core material cannot meet the GB 8624-2012A-level requirement, and fire safety hazards such as fire spread and even bombing exist in a fire scene.

The positive progress effects of the invention are as follows: the preparation method of the fireproof polystyrene insulation board is simple, only one set of negative-pressure fireproof coating modification equipment needs to be added on the basis of production of the traditional EPS foam insulation board, the equipment investment is low, the production period is short, and the fireproof polystyrene insulation board is beneficial to industrial popularization and application.
In addition, the fireproof heat-preservation adhesive is compounded by mixing a sulfate solution with light-burned magnesium oxide (MgO) powder, and adding a curing modifier, a waterproof modifier, a flame retardant, a heat-insulation additive and an infrared opacifier, and is air-hardening multi-element composite MgO-MgSO4-H2The fireproof heat-insulating adhesive has the advantages of reaction at normal temperature, no need of sintering and steam curing, light weight, high strength, fire resistance, quick condensation, sound insulation, heat insulation, fire resistance temperature of more than 1400 ℃ and the like. On the one hand the multielement compositionSynthetic MgO-MgSO4-H2The O air-hardening magnesium inorganic fireproof heat-insulation cementing material contains 12% of hydrated crystals, has the functions of absorbing heat and reducing temperature during combustion in a fire scene, and can play a synergistic fireproof effect with the flame-retardant system, so that when the requirement that the heat value of the A-grade EPS heat-insulation plate is less than 3.0MJ/kg is met, the addition amount of the flame retardant and the inorganic filler which need to be added is smaller, and the specific gravity of the heat-insulation plate is reduced. On the other hand, as the adhesive formula contains the heat insulation additive and the infrared opacifier, the fireproof heat insulation adhesive has the heat insulation performance, and can generate a synergistic effect with the heat insulation effect of the EPS heat insulation board, so that the heat conductivity coefficient of the modified flame-retardant EPS fireproof heat insulation board is further reduced. Meanwhile, the fire-resistant temperature of the inorganic fireproof heat-insulating adhesive reaches above 1400 ℃, so that the carbon layer framework of the modified A-grade EPS heat-insulating plate is stable and does not fall off after being combusted in a fire scene.
Finally, the specific gravity of the A2-grade polystyrene fireproof insulation board is less than 80kg/m3The heat conductivity coefficient is small by 0.045 w/m.k, the compressive strength of 10% deformation is greater than 200KPa, the toxicity of flue gas reaches ZA1 level, the oxygen index reaches more than 70, and the combustion performance reaches the requirement that the heat value specified by GB8624-2012 is less than 3.0 MJ/kg. Better overcomes the defect that the specific gravity of the traditional inorganic insulation board is more than 260Kg/M3The thermal conductivity is more than 0.063 w/m.k. Meanwhile, after the EPS fireproof insulation board is subjected to fireproof modification, the EPS fireproof insulation board is MgO-MgSO4-H2The curing gelling reaction of the O inorganic fireproof heat-insulating adhesive can completely cure the board after 5 hours, and the production period of the board is shortened. In addition, the fireproof polystyrene heat-insulation board can effectively solve the potential safety hazards that the traditional organic heat-insulation color steel plates such as polystyrene have poor combustion performance, strong smoke toxicity and easy collapse in a fire scene, the traditional inorganic color steel plates such as rock wool and glass wool have poor heat-insulation performance, the boards have limited moisture absorption, bulging and deformation and limited repeated use times, the materials are easy to pulverize, dust is filled in the production and construction process, workers and the environment are greatly influenced, and the like.
The color steel plate prepared by the invention structurally adopts the integrated combination of the groove-shaped side plate, the groove-shaped closing plate and the upper and lower panels, when the surface of the sandwich color steel plate is stressed, the groove-shaped structures of the side plate and the closing plate play a role of an external supporting frame due to the integrated reinforcement of the edges of the side plate, the closing plate, the panel and the core plate, and the bending strength of the sandwich color steel plate when the surface is stressed is further improved; on the other hand, because the core plate, the side plates, the sealing plates and the upper and lower panels are combined into a whole, on one hand, the bending strength of the sandwich color steel plate is improved when the surface of the sandwich color steel plate is stressed, and on the other hand, the problems that the existing color steel sandwich plate is poor in bonding strength, and a color steel plate house is easy to collapse in a fire scene can be effectively solved. The composite material has the advantages of high bending resistance and compressive strength, good tolerance and the like, and can effectively solve the potential safety hazards that the traditional organic heat-preservation color steel plates such as polystyrene and the like have poor combustion performance, strong smoke toxicity and easy collapse in a fire scene, the traditional inorganic color steel plates such as rock wool and glass wool have poor heat-preservation and heat-insulation performance, the plates have limited moisture absorption, bulging and deformation and limited repeated use times, the materials are easy to pulverize, dust is filled in the production and construction process, and the influence on workers and the environment is great.

Detailed Description
Example 1 examples 1 to 6 and comparative examples 1 to 2
Step 1) preparation of a polystyrene foam substrate
Polystyrene pre-expanded particles with the density of 5-15 g/L are used as raw materials, and the steam penetration pressure P is1MPa, vapor breakthrough time t1Polystyrene foam boards were prepared as follows.
Step 2) preparation of fireproof polystyrene heat-insulation board

Step 3) preparing the polystyrene color steel sandwich panel
As shown in fig. 1 to 4, four sides of the front color steel plate 12 and the back color steel plate 14 are folded by 90 degrees to the inner surface by using a folding machine to form four covered edges 16; and then the two opposite side edges of the two side plates 22 and the two close plates 24 are respectively folded by 90 degrees towards the outer surface by using a flanging machine to form a 90-degree flanging 222 and a 90-degree flanging 242.
The inner surfaces of the back color steel plates 14 are respectively and uniformly coated with a binder (such as the binders shown in table 3), the polystyrene fireproof heat-insulation plate 30 is bonded on the inner surface of the back color steel plates 14, the other surfaces of the polystyrene fireproof heat-insulation plates are uniformly coated with the binder, and then the front color steel plates 12 are bonded on the other surfaces of the polystyrene fireproof heat-insulation plates 30, so that the polystyrene fireproof heat-insulation plates are bonded as a core plate and clamped between the front color steel plates 12 and the back color steel plates 14.
The inner sides of the two side plates 22 are coated with adhesive and are respectively adhered to the two long sides of the core plate 30, and the two 90-degree folded edges 222 of the side plates 22 are respectively folded inwards by 90 degrees by the covered edges 16 of the color steel plates 12 and 14 so as to wrap and buckle the two 90-degree folded edges 222 of the side plates 22, thereby forming an interface reinforced edge and a socket reinforced edge.

TABLE 2 fireproof thermal insulation adhesive formulation
The fireproof heat-preservation adhesive is obtained by weighing the above substances in parts by weight, fully stirring and uniformly dispersing.
TABLE 3 Sandwich color steel plate bonding layer and structure
The properties of the obtained flame-retardant EPS foam insulation board were tested, as shown in Table 4.
TABLE 4 Performance parameters of A-class EPS foam sandwich color steel plate
The heat conductivity coefficient of the heat insulation board core material is lower than 0.045 w/m.k, and the specific gravity of the core material can reach 80Kg/M3The 10% deformation compressive strength of the core material is more than 200KPa, the heat value is less than 3MJ/kg, and the requirement of GB8624-2012 building material on grade A2 fire-resistant grade of combustion performance is met. The protective heat-preservation adhesive is mainly characterized in that the protective heat-preservation adhesive is compounded by air-hardening multi-element composite MgO-MgSO (magnesium oxide-magnesium sulfate) formed by mixing sulfate solution with light-burned magnesium oxide (MgO) powder, and adding a curing modifier, a waterproof modifier, a flame retardant, a heat-insulation additive and an infrared opacifier4-H2O inorganic fireproof heat-insulating cementing material, namely the multi-element composite MgO-MgSO4-H2The O air-hardening magnesium inorganic fireproof heat-insulation cementing material contains 12% of hydrated crystals, has the functions of absorbing heat and reducing temperature during combustion in a fire scene, and can play a synergistic fireproof effect with the flame-retardant system, so that when the requirement that the heat value of the A-grade EPS heat-insulation plate is less than 3.0MJ/kg is met, the addition amount of the flame retardant and the inorganic filler which need to be added is smaller, and the specific gravity of the heat-insulation plate is reduced. On the other hand, the air-hardening multi-element composite MgO-MgSO (magnesium oxide-magnesium sulfate) compounded by the fireproof adhesive disclosed by the invention4-H2The compression strength of the O inorganic fireproof heat-insulating cementing material is high, so that the compression strength of the core material with 10% deformation is more than 200 KPa.
In comparative example 1, the flame retardant, the heat insulating filler and the infrared screening agent of the present invention were not used, but only the air-hardening MgO-MgSO, which is prepared by adding the sulfate solution, blending the light-burned magnesium oxide (MgO) powder, and adding the curing modifier and the water-proofing modifier4-H2The O inorganic fireproof heat-insulating cementing material has light specific gravity and higher heat value due to no addition of the flame retardant and the flame-retardant synergist, and cannot meet the requirement that the A2 grade heat value is less than 3 MJ/kg. The flame-retardant synergistic formula of the fireproof heat-insulation adhesive can dilute the heat value of the polystyrene foam heat-insulation board, and can absorb heat through decomposition of the flame retardantThe heat value is offset, so that the polystyrene foam heat-insulation board can reach the requirement that the A2 grade heat value is less than 3MJ/kg under the condition of lower specific gravity, and the heat conductivity coefficient is relatively lower due to the small addition amount of the inorganic filler.
Comparative example 2, the thermal conductivity of the warm plate core material is less than 0.063 w/m.k, and the specific gravity of the core material can reach 120Kg/M3The core material has the deformation compressive strength of 135KPa of 10 percent, and has higher heat conductivity coefficient and higher specific gravity than the core material of the heat-insulating board of the invention, and has the deformation compressive strength of 10 percent less than the core material of the heat-insulating board of the invention. The reason is that the fire-proof adhesive in the comparative example 2 adopts 30% sodium silicate aqueous solution as the adhesive, and under the condition that the fire-proof heat-preservation adhesive has no change with other formulations, the adhesive and the flame-retardant system do not play a synergistic flame-retardant role, so that when the heat value of the plate reaches the requirement that the A2 grade heat value is less than 3MJ/kg, the specific gravity of the heat-preservation plate is larger than that of the invention. The fireproof heat-preservation adhesive is compounded by mixing a sulfate solution with light-burned magnesium oxide (MgO) powder, and adding a curing modifier, a waterproof modifier, a flame retardant, a heat-insulation additive and an infrared opacifier to form air-hardness multi-element compound MgO-MgSO (magnesium oxide-MgSO)4-H2The fireproof heat-insulation adhesive contains 12% of hydrated crystals, has a heat absorption and cooling effect when being combusted in a fire scene, has a synergistic heat absorption and cooling effect with a flame-retardant system, and has the advantages that when the requirement that the heat value of an A-grade EPS heat-insulation board is less than 3.0MJ/kg is met, the addition amount of a flame retardant and an inorganic filler which need to be added is small, the specific gravity of the heat-insulation board is reduced, and the heat conductivity coefficient of the heat-insulation board is further reduced. In addition, the compression strength of the air-hardening cementing material compounded by the sulfate solution and the light-burned magnesia (MgO) powder is high, so that the compression strength of the 10% deformation of the core material is greater than 200KPa, which is higher than that of the 10% deformation of the core material in comparative example 2.
In the embodiment 6, as the heat insulation additive and the infrared opacifier are not added, the fireproof adhesive has only a fireproof effect and does not have a heat insulation function, and cannot exert a heat insulation synergistic effect with the EPS foam board, so that the prepared EPS foam heat insulation board has a relatively large heat conductivity coefficient under the condition of the same specific gravity as the fireproof heat insulation adhesive in the embodiments 1 to 5.
In the aspect of color steel sandwich panel preparation, the invention adopts the integrated combination of the groove-shaped side plate, the groove-shaped closing plate and the upper and lower panels in structure, when the surface of the sandwich color steel panel is stressed, because the edges of the side plate, the closing plate, the panel and the core plate are integrally reinforced, and the groove-shaped structures of the side plate and the closing plate play a role of an outer supporting frame, the bending strength of the sandwich color steel panel when the surface is stressed is further improved; on the other hand, because the core plate, the side plates, the sealing plates and the upper and lower panels are combined into a whole, on one hand, the bending strength of the sandwich color steel plate is improved when the surface of the sandwich color steel plate is stressed, and on the other hand, the problems that the existing color steel sandwich plate is poor in bonding strength, and a color steel plate house is easy to collapse in a fire scene can be effectively solved.
