Problems solved by technology

For a long time, the insulation material of the wall insulation board has mostly used foamed plastic boards with low thermal conductivity such as polystyrene foam (EPS) or polystyrene extruded board (XPS). Foamed plastics are flammable materials. In the event of a fire, the foam insulation material will be softened by high temperature, causing it to fall off. In severe cases, it will also support combustion. The poisonous gas released by the combustion will cause people to be poisoned, comatose or even dead; secondly, the untreated waste polyphenylene particles have caused white pollution to the environment.

Abstract

The invention discloses a cement-base light fireproof wall body heat insulation board and a preparation method thereof. The cement-base light fireproof wall body heat insulation board consists of a heat insulation layer and a protection layer. The heat insulation layer comprises the following components in parts by mass: 85-89 parts of Portland cement, 2-5 parts of polyphenyl particles, 5-8 parts of vinyl acetate - ethylene copolymer emulsion and 2.5-3.3 parts of additive; and the protection layer consists of the following components in parts by mass: 84-90 parts of Portland cement, 9-15 parts of sulphoaluminate cement, 0.1-0.2 part of glass fiber and 0.6-0.8 part of super plasticizer. Heat insulation layer slurry is filled into a mold for molding to form the heat insulation layer with thickness being 2-3cm; an alkali-resisting glass fiber grid cloth is tightened, is attached onto the surface layer of the heat insulation layer and is pressed into the surface layer of the heat insulation layer; a protection layer slurry layer with thickness being 1-2mm is coated on the surface layer of the heat insulation layer; and pressure shaping, curing and drying are conducted to obtain the cement-base light fireproof wall body heat insulation board. The cement-base light fireproof wall body heat insulation board has the advantages of light weight, high strength, water and damp prevention, fire prevention, convenience in building construction and the like.

Description

technical field [0001] The invention relates to the technical field of a new type of wall material, in particular to a cement-based light-weight firewall body insulation board with light weight, waterproof and fireproof functions prepared from cement and waste polyphenylene particles as main raw materials and its Preparation. Background technique [0002] The wall insulation board is a building component used on the outer surface of the wall to provide thermal insulation for the building. For a long time, the insulation material of the wall insulation board has mostly used foamed plastic boards with low thermal conductivity such as polystyrene foam (EPS) or polystyrene extruded board (XPS). Foamed plastics are flammable materials. In the event of a fire, the foam insulation material will be softened by high temperature, causing it to fall off. In severe cases, it will also support combustion. The poisonous gas released by the combustion will cause poisoning, coma or even de...
