Vermiculite fireproof thermal-insulation sound-insulation sheet material and preparation method thereof

Abstract

The invention relates to a vermiculite fireproof thermal-insulation sound-insulation sheet material and a preparation method thereof. The vermiculite fireproof thermal-insulation sound-insulation sheet material is prepared by compacting the raw materials: in percents by weight, 50-70% of expanded vermiculite, 10-15% of expanded vitrified vermiculite powder, 5-15% of expanded vitrified pitchstone,5-15% of fly ash floating bead and 5-10% of an aqueous binder. The vermiculite fireproof thermal-insulation sound-insulation sheet material has excellent fireproof thermal-insulation sound-insulation performance, and makes up the disadvantages that lightweight aggregate prepared from an organic material is bad in fireproofness, is easy to deform severely at a high temperature and causes shedding and melt dropping and causes injuries on people, and generates harmful gas at a high temperature and causes environmental pollution. The vermiculite fireproof thermal-insulation sound-insulation sheet material is good in fireproof thermal-insulation sound-insulation effect, stable in structure, has a same service life with buildings, and also has the advantages of being energy-saving, none in pollution and economical.

Description

【Technical field】 [0001] The invention relates to a decorative board for interior and exterior walls and a preparation method thereof, in particular to a vermiculite fire-proof, heat-preserving and sound-insulating board and a preparation method thereof, belonging to the technical field of decorative boards. 【Background technique】 [0002] The fire-proof, heat-insulation and sound-insulation boards in the prior art are mostly made of extruded plastic boards, foamed cement boards, etc., which have the following disadvantages: poor fire resistance, ineffective heat preservation and sound insulation, high energy consumption of materials, not environmentally friendly, and pollution to the environment after being discarded. It cannot have the functions of fire prevention, heat preservation and sound insulation and environmental protection at the same time. [0003] Therefore, in order to avoid the above-mentioned technical problems, it is indeed necessary to provide a new vermicu...
