Imitation stone thermal insulating decoration board and making process thereof

Abstract

The invention discloses an imitation stone thermal insulating decoration board and a making process thereof, relating to a technology for producing a thermal insulating decoration board for a wall. The thermal insulating decoration board is completely made from magnesium oxide, magnesium chloride, real stone particles and other organic materials which are combined into a main frame, and a phenolic foam board is attached in the main frame as a thermal insulating layer; and the parts are assembled in a separated-module manner, fastened through mortise and riveted through a metal anchor. The components of the raw material comprise magnesium oxide, magnesium chloride solution, sodium hexametaphosphate, melamine formaldehyde resin, waterproof agent, purifying agent, silicon powder, real stone particles and glass fiber. The steps of confecting magnesium chloride solution, confecting organic material paste, molding, curing / de-molding and painting are performed to obtain an imitation stone thermal insulating decoration board. The product of the invention is incombustible and superior in heat resistance, enhances the strength, hardness and aging-resistant performance of the product; moreover, the construction period is short, the labor intensity is small and the comprehensive maintenance cost is low. The product avoids the problems that engineering construction is often subjected to bulge, cracking, drop and water seepage, the thermal insulating layer shrinks and deforms, the outer layer cracks at high temperature and the like.

Description

technical field [0001] The invention relates to a production technology of a wall thermal insulation decorative board. technical background [0002] At present, the external wall insulation technology mostly uses adhesive mortar to paste insulation boards (polyurethane foam boards, polystyrene foam boards) on the wall base, anchors are fixed, grid cloth is pasted, and the mortar layer is applied to the outside before surface decoration, such as Hanging marble, veneer tiles, brushing paint, etc. Exterior wall insulation materials and product installation have complicated production process, long construction period, high labor intensity, and hidden quality problems such as bulging, cracking, falling off, and water seepage often occur after construction, especially in terms of fire and flame retardant requirements. Obviously, a large area of ​​thermal insulation layer shrinks and deforms under high temperature, which leads to greater hidden dangers caused by cracking and fall...

Problems solved by technology

[0003] The purpose of the present invention is to provide a stone imitation thermal insulation decorative board and its production process to solve the complex production process, long construction period, high labor intensity, poor fireproof, flame retardant and heat resistance effect of the prior art, and the large-area thermal insulation layer under high temperature is easy to solve. Shrinkage and deformation lead to cracking of the outer layer, and problems such as bulging, cracking, falling off, and water seepage often occur in the application after engineering construction
