Problems solved by technology

[0004] On the other hand, the existing thermal insulation and decoration integrated boards are all composed of inorganic composite decorative layers plus organic flammable thermal insulation layers.
This kind of structure has low fire resistance, and the bonding part of the inorganic layer and the organic layer has different expansion coefficients due to different materials, so it is easy to separate and fall off in hot and cold environments, and the product life is not long.

Abstract

The present invention proposes a preparation method of polystyrene grade A non-combustible building exterior wall thermal insulation decorative board, comprising the steps of: (1) banburying 100 parts of XPS for 20-30 minutes, adding nucleating agent, smoke suppressant, and char-forming agent , stabilizer, phase solvent and flame retardant, continue banburying after mixing, and get granules for subsequent use; (2) get wherein 95-99 mass parts of granules are placed in foaming extruder equipment to make plates; (3) Add sodium silicate banburying for 25 minutes with the remaining granules, place in a film laminating machine, take (2) the board obtained in the film laminating machine, add 15 kg of pressure and heat film to obtain a film laminating board. The method proposed by the present invention produces an organic XPS material, which is non-combustible, non-toxic, tasteless, safe and environmentally friendly, heat-insulating, and weather-resistant, and has the brightness and cleanliness of ceramic tiles, and is integrated without decoration. The external wall insulation board expands the application field of external wall insulation and decoration-free materials.

Description

technical field [0001] The invention belongs to the field of organic polymer compositions, and in particular relates to a preparation method of a polymer material with polystyrene as a base material and the obtained product. Background technique [0002] The thermal insulation integrated board is composed of adhesive layer, thermal insulation and decorative finished board, anchors, sealing materials and so on. At the same time, it has the functions of heat preservation and decoration.
