Bactericidal flame-retardant smoke-proof moisture-proof non-toxic environmentally-friendly sound-insulating material and preparation method thereof

Abstract

The invention discloses a bactericidal flame-retardant smoke-proof moisture-proof non-toxic environmentally-friendly sound-insulating material and a preparation method thereof, the bactericidal flame-retardant smoke-proof moisture-proof non-toxic environmentally-friendly sound-insulating material comprises the following raw materials by weight: 8-12 parts of a smoke-proof flame-retardant additive,3-5 parts of a coupling agent, 3 to 5 parts of a bactericidal additive, 8 to 10 parts of modified fiber, 15 to 25 parts of a sound insulation additive, 3 to 5 of white carbon black, 12 to 14 parts ofa modified filler, 1 to 2 parts of nano zinc oxide, 1 to 3 nano titanium dioxide, 20 to 30 parts of an ethylene acrylic acid copolymer, 2 to 4 parts of a polyether polyol, 4 to 6 parts of a polyurethane emulsion, 0.7 to 1.1 parts of an antioxidant, 1 to 2 parts of a stabilizer, and 1 to 2 parts of a lubricant. The bactericidal flame-retardant smoke-proof moisture-proof non-toxic environmentally-friendly sound-insulating material has good sound insulation performance and excellent mechanical performance, has obvious flame-retarding and smoke-suppressing effect, excellent sterilization and mildew resistance, good moisture proofness and weather resistance, and no volatile harmful substances, and is non-toxic, environmentally-friendly and non-polluting; the cost of the preparation method is low, the raw materials are easy to obtain, and the bactericidal flame-retardant smoke-proof moisture-proof non-toxic environmentally-friendly sound-insulating material has high practical value and goodapplication prospects.

Description

technical field [0001] The invention relates to the technical field of building sound insulation materials, in particular to a sterilizing, flame-retardant, smoke-suppressing, moisture-proof, non-toxic and environmentally friendly sound-insulating material and a preparation method thereof. Background technique [0002] At present, noise has become a major environmental pollution, and people pay more and more attention to the problem of acoustic environment. Selecting appropriate materials for sound absorption and sound insulation is one of the most commonly used and basic technical measures in noise control engineering. The difference between material sound absorption and material sound insulation is that material sound absorption focuses on the size of the reflected sound energy on one side of the sound source, and the goal is to reduce the reflected sound energy; material sound insulation focuses on the size of the transmitted sound energy on the other side of the incident...

AI Technical Summary

Problems solved by technology

[0003] Nowadays, there are many kinds of sound insulation materials, such as solid bricks, reinforced concrete walls, wood boards, gypsum boards, iron plates, sound insulation felts, fiberboards, etc., which are more common, but these sound insulation materials usually have disadvantages such as poor environmental protection or unsatisfactory sound insulation performance.

At the same time, some sound insulation materials are easy to breed bacteria and emit toxic and harmful gases, which are very harmful to the environment and human health.

[0004] In addition, the weather resistance and flame retardant performance of most sound insulation materials are not good enough, and a large amount of black smoke is easy to be generated when burning, which has great hidden dangers to human health.
