Abstract

The invention discloses a fireproof sound-insulation building thermal-insulation composite board and a preparation method thereof. The fireproof sound-insulation building thermal-insulation composite board comprises the following raw materials in parts by weight: 19-25 parts of Portland cement, 15-25 parts of glass fiber, 16-20 parts of phenolic foam particle, 22-33 parts of polystyrene, 10-15 parts of coated vitrified microsphere, 11-23 parts of polyether glycol, 5-15 parts of bentonite, 9-18 parts of fly ash, 15-25 parts of sodium methane-silicate, 15-20 parts of magnesium chloride, 8-15 parts of redispersible latex powder, 3-8 parts of inorganic reinforcing fiber, 2-11 parts of butyl propionate and 5-14 parts of EPS (expandable polystyrene) particle. The glass fibers have very high toughness, so that the properties of the board are greatly enhanced in the use process, and the board has higher stability. Under the interactions of the Portland cement, glass fibers, phenolic foam particles, polystyrene, polyether glycol, fly ash, EPS particles and the like, the board has the properties of thermal insulation, water resistance and decoration. The composite thermal-insulation board has high heat stability, and is a composite thermal-insulation board with excellent properties.

Description

technical field [0001] The invention relates to the technical field of composite plate production, in particular to a fire-proof and sound-insulating building thermal insulation composite plate and a preparation method thereof. Background technique [0002] In recent years, my country's building energy-saving wall insulation market has developed rapidly, and insulation system products emerge in endlessly. However, in the face of sudden fire accidents, many insulation materials are very fragile. Being able to prevent fire has become a very important indicator to measure whether a building is qualified or not. At present, the general wall insulation materials use organic or inorganic insulation boards. Organic insulation boards are mainly made of polystyrene. Polystyrene is an excellent insulation material, and it is supplemented by extrusion to form a tight honeycomb structure. , so as to prevent heat conduction very effectively. This kind of board has many advantages such ...
