Microvesicle glass fireproofing insulation board and production method thereof

Abstract

The invention discloses a microvesicle glass fireproofing insulation board and a production method thereof. The microvesicle glass fireproofing insulation board is characterized by comprising a mixed layer (1). The mixed layer (1) is formed by glass foam materials and binding materials in a mixing mode, or is formed by the glass foam materials, short fiber and the binding materials. Surface protective layers (2) are arranged on the upper surface and the lower surface of the mixed layer (1). The production method of the microvesicle glass fireproofing insulation board comprises the following steps: adding the glass foam materials and short fiber to a mixed device to be mixed with the binding materials; coating and laying the mixed materials on the surface protective layers; adding a surface protective layer on the surface of the mixed materials, carrying out lamination after entering a lamination machine, drying, solidifying, and then carrying out cutting and packing after molding. According to the microvesicle glass fireproofing insulation board and the production method thereof, technical formula design is reasonable, a small amount of binding materials and reasonable binding conditions are selected to be used on the premise that binding strength is ensured, the fact that existing thermal resistance of the glass foam materials is not reduced is ensured, and the made insulation board is noncombustible materials with grade A and can be used for a building energy conservation exterior wall external insulation project.

Description

Technical field: [0001] The invention relates to a microbubble glass fireproof heat preservation board and a production method thereof, belonging to the technical field of building materials. Background technique: [0002] At present, the traditional external wall insulation board mainly includes two types, one is inorganic insulation board, and the other is organic insulation board. The fire resistance grade of organic insulation board can only reach Class B, while inorganic insulation board, The fire-resistant grade can reach Class A. At present, the thermal conductivity of thermal insulation materials that can reach the envelope structure on the market should generally be controlled below 0.05. At present, there are vitrified microbeads, microfoamed glass, glass fiber felt, and pearls that meet this requirement.

Problems solved by technology

[0002] At present, the traditional external wall insulation board mainly includes two types, one is inorganic insulation board, and the other is organic insulation board. The fire resistance grade of organic insulation board can only reach Class B, while inorganic insulation board, The fire-resistant grade can reach Class A. At present, the thermal conductivity of thermal insulation materials that can reach the envelope structure on the market should generally be controlled below 0.05. At present, there are vitrified microbeads, microfoamed glass, glass fiber felt, and pearls that meet this requirement. Rock, rock wool, aluminum silicate wool, asbestos, composite silicate and other materials and inorganic vacuum insulation boards. Inorganic vacuum insulation boards are limited in use because they cannot be nailed through and cut and broken. Fiberglass felt, perlite, rock wool, silicon The low surface strength of aluminum wool, asbestos, composite silicate, etc. makes the safety of bonding to the wall poor, and the poor water resistance affects the thermal insulation effect. Because the vitrified microbeads and microfoamed glass are granular, they must meet the needs of the project. The method is to make thermal insulation mortar, and then smear it on the outer wall. This method greatly increases the original thermal conductivity of vitrified microbeads and microfoam foam glass, and loses its role as a separate thermal insulation layer, which also limits market applications. to promote
