Abstract

The invention discloses a nano attapulgite modified composite sound absorbing material. The material is prepared from the following raw materials in parts by weight: 100-120 parts of barite powder, 50-60 parts of ceramsite, 40-50 parts of nano attapulgite, 80-90 parts of styrene-acrylic emulsion, 55-65 parts of modified tree ashes, 15-20 parts of zinc borate, 20-30 parts of mineral wool fibers, 10-20 parts of nanocarbon, 20-30 parts of EVA (ethylene-vinyl acetate copolymer), 15-20 parts of POE (polyolefin elastomer), 5-10 parts of EMDP, 5-8 parts of trioctyl trimellitate, 4-6 parts of triphenyl phosphate, 2-3 parts of zinc stearate and 1-2 parts of dibasic lead phosphite. The material has the beneficial effects that the problem of developing and researching the sound absorbing material urgently is solved and the novel sound absorbing material which meets the requirements, can stand the tests of harsh environments and has the advantages of high tensile strength, high elongation, high breaking strength, good sound absorbing effect and the like is prepared.

Description

technical field [0001] The invention relates to a nano-attapulgite-modified composite sound-absorbing material and a preparation method thereof, belonging to the technical field of material research and production. [0002] Background technique [0003] With the development of industrial production, transportation, and urban construction, as well as the increase of population density and the increase of household facilities (audio, air conditioning, television, etc.), environmental noise is becoming more and more serious, and it has become a major public hazard that pollutes the human social environment. Noise not only affects hearing, but also has adverse effects on the human cardiovascular system, nervous system, and endocrine system. [0004] Existing sound-absorbing materials also have composite types, but few have excellent performance indicators for composites of inorganic materials and organic materials. On the whole, my country's sound-absorbing material industry ha...
