Fireproof heat-insulation outer wall composite decoration plate

Abstract

The invention relates to a fireproof heat-insulation outer wall composite decoration plate comprising an aluminum-zinc alloy steel structure, the aluminum-zinc alloy steel structure is in a net-structure-face shape, and a composite layer is embedded to the aluminum-zinc alloy steel structure. The aluminum-zinc alloy steel structure is covered with the composite layer completely, and the composite layer comprises, by mass, 45-60% of phenolic resin foam, 12-22% of melamine fibers, 10-20% of inorganic heat insulation mortar, 3-8% of titanium dioxide, 4-10% of coal ash, 3-8% of perlite and 2-6% of magnesium oxide. The outer surface of the composite layer is coated with enamel polyester paint or fluorocarbon paint. According to the fireproof heat-insulation outer wall composite decoration plate, a traditional laminated structure is abandoned, and high-temperature-resistance, anti-fire and fire-insulation performance is good; and meanwhile the structure is more stable, the mass is small, and safety is higher in actual assembling.

Description

technical field [0001] The invention belongs to the technical field of indoor and outdoor decoration, and relates to a composite decorative board for fireproof and thermal insulation exterior walls. Background technique [0002] Traditional exterior wall thermal insulation and fireproof decorative panels mainly include surface layer or outer finish layer (often using galvanized color printed steel plate, galvanized color-coated plate, aluminum-magnesium-manganese plate), sandwich layer or called insulation layer (often using EPS Polystyrene board, XPS extruded board, PUR polyurethane board), bottom layer or lining (usually aluminum foil, PVC or metal color-coated board). In terms of the direction of research and development of exterior wall thermal insulation and fireproof decorative panels in recent years, many new integrated materials for exterior wall decoration and thermal insulation have emerged. This composite decorative panel material is mainly composed of aluminum-zi...
