Thermal insulating polymer composite glass fiber flame-retardant facing material for wall body

Abstract

The invention relates to a thermal insulating polymer composite glass fiber flame-retardant facing material for a wall body. According to the facing material, a reinforced glass fiber mat is adopted as a substrate, and a polymer flame-retardant cement mortar coating is coated through an advanced coating process. The polymer flame-retardant cement mortar coating is prepared by the following steps:(1) uniformly mixing and stirring a silane coupling agent KH-560, a dispersant K-1900 and water; (2) adding an acrylic polymer (45-50%), cement and sand into the uniformly stirred mixture, and fully and uniformly stirring at a speed of 800-1,200r / min; and (3) after uniformly stirring, adding a cellulosic thickener such as hydroxyethylcellulose, finally adding a flame retardant (non halogen class,99%) and uniformly stirring for later use. The thermal insulating polymer composite glass fiber flame-retardant facing material provided by the invention has the advantages of good flame retardance, high flatness, good thermal insulation system and light weight of appearance.

Description

technical field [0001] The invention relates to a coating, in particular, a reinforced glass fiber thin mat is used as a base to prepare a wall thermal insulation polymer composite glass fiber flame-retardant veneer material through an advanced coating process. Background technique [0002] Wall insulation refers to the use of certain fixing methods (bonding, mechanical anchoring, sticking + mechanical anchoring, spraying, pouring, etc.), and the thermal insulation material with low thermal conductivity (better thermal insulation effect) is fixed with the building wall. , an engineering practice that increases the average thermal resistance of the wall to achieve thermal insulation or thermal insulation. Polyurethane foam materials have only been introduced in recent years and are used for thermal insulation and waterproofing of building walls. Polyurethane material is internationally recognized as the insulation material with the best performance. About 49% of the buildin...

Problems solved by technology

More than 200 square meters can be wiped per job per day, and during the production process, due to the frequent interruption of cement solidification, the slow speed is not conducive to rushing the progress

There is a large amount of wiping pressure, thick thickness and heavy weight. If there is a slight difference in fixing, it will easily cause falling off and cause safety hazards. If the amount of wiping pressure is reduced, there will be polyurethane penetration, which will directly affect the bonding strength between the surface decoration and the wall.
