Composite building heat-insulation board

Abstract

The invention discloses a composite building heat-insulation board which is prepared from, by weight, 30-50 parts of cement, 10-15 parts of bamboo charcoal, 5-10 parts of perlite, 8-15 parts of sepiolite powder, 12-15 parts of organosilicon modified epoxy resin, 12-18 parts of gypsum, 15-25 parts of polyurethane waterproof paint, 4-9 parts of polyester fiber, 10-20 parts of sodium silicate solution, 2-10 parts of polyacrylamide, 1-8 parts of tributyl phosphate, 11-17 parts of acrylate, 2-8 parts of hydroxypropyl methyl cellulose, 1-8 parts of chromium boride and 2-8 parts of synthetic rubber. The composite building heat-insulation board can effectively integrate advantages of conventional organic boards and inorganic boards, can reach heat-insulation performance grade of organic materials, has performances like noninflammability of inorganic materials, are high in durability and weatherability and can be in service as long as a building is in service.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a composite building insulation board. Background technique [0002] Building materials can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, bamboo, stone, cement, concrete, metal, bricks, ceramics, glass, engineering plastics, composite materials, etc.; decorative materials include various coatings, paints, coatings, veneers, tiles of various colors, and special effects Glass, etc.; special materials refer to waterproof, moisture-proof, anti-corrosion, fire-proof, flame-retardant, sound insulation, heat insulation, heat preservation, sealing, etc. There are many types of thermal insulation materials, and the application range is also very wide. The more commonly used ones are: glass wool products, Vinai insulation blanket, insulation foam glass, polyurethane, etc. Glass wool produc...

AI Technical Summary

Problems solved by technology

EPS, XPS, and PU are all organic thermal insulation materials. The biggest advantage is light weight, heat preservation, and good heat insulation; the biggest defect is fire prevention, poor safety, easy aging, easy to burn, large smoke, high toxicity, and low load-bearing capacity when burning. , service life, and fire resistance are not as good as inorganic insulation materials
