Abstract

The invention relates to a compound plate and a preparation method of the plate, particularly relates to a vermiculite-based sandwich structure type non-combustible plate and a preparation method of the plate, and belongs to the crossing field of fire science and building and ornament materials. The vermiculite-based sandwich structure type non-combustible plate comprises an expanded fireproof heat-insulation vermiculite plate and an ultrathin fireproof vermiculite-based plate, and the ultrathin fireproof vermiculite-based plate is compounded on the surface layer of the fireproof heat-insulation expanded vermiculite plate. The preparation method of the vermiculite-based sandwich structure type non-combustible plate comprises the steps: compounding the expanded fireproof heat-insulation vermiculite plate and the ultrathin fireproof vermiculite-based plate through an adhesive, and compounding in a single layer manner or in an upper-lower surface layer manner according to the demand. According to the preparation method of the vermiculite-based sandwich structure type non-combustible plate, provided by the invention, the expanded fireproof heat-insulation vermiculite plate and the ultrathin fireproof vermiculite-based plate are compound, the thickness of the ultrathin fireproof vermiculite-based plate is 4mm, and the thickness of the expanded fireproof heat-insulation vermiculite plate is 12mm, and thus a sandwich structure is formed. The vermiculite-based sandwich structure type non-combustible plate has multiple functions of high strength, fireproof performance, moisture prevention, water resistance, heat insulation, sound insulation and the like.

Description

technical field [0001] The invention relates to a composite board and a preparation method thereof, in particular to a non-combustible board with a vermiculite-based sandwich structure and a preparation method thereof, which belongs to the intersection field of fire science and building decoration materials. Background technique [0002] With the rise of the construction industry and the increase of high-rise buildings, there have been new problems in fire safety. People's requirements for living environment are getting higher and higher, and the fire performance of indoor decoration materials such as interior decorative panels and detachable furniture needs to be further improved. At present, the commonly used materials for interior decoration walls mainly include wall bricks, wood plywood, density boards, and wallpapers. The commonly used materials for furniture and kitchen utensils mainly include plywood, MDF and plywood. Although these materials are used in a wide rang...
