Sound insulation and adsorption material for indoor decoration and preparation method thereof

Abstract

The invention discloses a sound insulation and adsorption material for indoor decoration and a preparation method thereof. The method includes: firstly preparing modified montmorillonite; then taking 25-35 parts of modified montmorillonite, 40-65 parts of a molecular sieve, 15-28 parts of D-mannitol and 38-45 parts of a water soluble polyurethane emulsion, and adding them into a reactor to carry out stirring reaction; then grinding 10-15 parts of ascharite, 8-18 parts of anatase and 4-10 parts of zirconium silicate, then adding the grinding product into the reactor to conduct further stirring; adding 5-10 parts of a carboxymethyl cellulose ammonium salt, 4-8 parts of antimony pentoxide sol and 8-15 parts of a silane coupling agent into the reactor in order, heating the reaction liquid to 80-120DEG C, and carrying out reaction under continuous stirring; and finally adding the mixture into a double-screw extruder to conduct extrusion molding, thus obtaining the sound insulation and adsorption material. The sound insulation and adsorption material provided by the invention has good adsorption performance and sound insulation effect at the same time, and can reach the purposes of purifying indoor air and obstructing noise.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a sound-insulating and absorbing material for interior decoration and a preparation method thereof. Background technique [0002] Clothing, food, housing and transportation are the basic needs of people's life, and the most important thing is housing. However, due to the lack of sound insulation materials or the poor performance of sound insulation materials in houses, the sound of walking on the floor upstairs, the crying of babies in the neighbors, and the quarrel between husband and wife can be introduced into our houses; more importantly, The voice of one's own family can also be transmitted to other families, which brings hidden dangers to the protection of privacy. There are many meals, restaurants, and barbecue restaurants gathered around today's residential areas. The resulting pollution and pollution from automobile exhaust will enter the room through the windows. If our...
