Thermal insulation board coating layer

Abstract

The invention discloses a thermal insulation board coating layer, and relates to the technical field of thermal insulation board, wherein the thermal insulation board coating layer comprises the components: hard polyurethane foam, ultra low density polyethylene, trichloroethylene, carboxymethyl chitosan, 3,4-dimethylpyrazolate, sodium aluminate, polyglycerol fatty acid ester, dicyclohexylcarbodiimide, 4-dimethylaminopyridine, p-methylbenzene sulfonic acid, terpene resin, ammonium polyphosphate, triphenyl phosphate, polyamide modified phenolic epoxy resin, aquadag, polytetrafluoroethylene, an organic bismuth antioxidant, a copper oxide powder, concentrated hydrochloric acid, silane, an antioxidant auxiliary agent, propylene asphaltic resin, an alkali solution, deionized water, and ethanol.The thermal insulation board coating is safe and non-toxic, has the advantages of good heat preservation, high temperature resistance, low temperature resistance, strong environment temperature difference sudden change resistance, and corrosion resistance, and can directly coat the surface of a thermal insulation board; through the processing treatment technology, the thermal insulation board withbetter thermal insulation effect is obtained, all layers are combined closely in use, the structure is stable, the structure design is beneficial to weight reduction and material saving, and economicinput in thermal insulation problem is reduced, and the cost performance ratio is high.

Description

Technical field: [0001] The invention relates to the technical field of thermal insulation boards, in particular to a coating of thermal insulation boards. Background technique: [0002] Insulation board is easy to understand that it is a board for building insulation. It is made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers. It is heated and mixed while injecting a catalyst, and then extruded and formed. Rigid foam plastic board has moisture-proof and waterproof properties, which can reduce the thickness of the building's outer protective structure, thereby increasing the indoor usable area. [0003] There are mainly three energy-saving methods for existing building envelope structures, namely, external thermal insulation of external walls, internal thermal insulation of external walls, and sandwich thermal insulation. These three thermal insulation methods have their own advantages and disadvantages. The advantage of external wal...

Problems solved by technology

These three insulation methods have their own advantages and disadvantages. The advantage of external wall insulation is that it can effectively avoid the generation of cold and heat bridges and effectively protect the main structure. However, its disadvantage is that it is relatively difficult to construct at present; The advantage is that the construction is relatively simple and the cost is low. However, its disadvantages are also obvious. It is difficult to avoid the generation of cold and heat bridges. The joint between the wall and the insulation layer is prone to condensation and mildew. The advantage of sandwich insulation is that its The requirements for thermal insulation materials, especially the strength requirements for thermal insulation materials are low, and the disadvantage is that the generation of cold and thermal bridges cannot be avoided, and the construction is difficult
