Abstract

The invention belongs to the field of building material plates, and discloses a vermiculite plate with sound insulation and fire protection functions. The vermiculite plate comprises, by weight, 20-60parts of expanded vermiculite, 5-20 parts of sound insulation materials, 10-50 parts of modified water glass, 3-25 parts of curing agents and 5-30 parts of water by pouring. The invention further discloses a preparation method of the vermiculite plate. The vermiculite plate has excellent sound insulation, heat insulation, fire protection and water resistance performances, and has the advantages of light weight, long-laid non-deformation, simple processing technology, high strength, good weather resistance, green and environmental protection.

Description

technical field [0001] The invention belongs to the field of building material boards, in particular to a vermiculite board with room temperature pressureless molding, remarkable sound insulation effect and fire prevention function and a preparation method thereof. Background technique [0002] Vermiculite is a layered structure of magnesium-containing hydroaluminosilicate secondary metamorphic minerals. It looks like mica. It is usually formed from black (gold) mother through hydrothermal alteration or weathering. Smoke, non-toxic, tasteless and other advantages, the fire resistance limit is as high as more than 4 hours, it is recognized as one of the best fire-proof and heat-insulating materials. When vermiculite is heated, it loses water and expands, and its volume can rapidly increase by 8 to 15 times, up to 30 times. Expanded vermiculite has the advantages of fire prevention, light weight, sound absorption, antibacterial, low thermal conductivity, etc. It is an excelle...
