Embodiment Construction

[0014] A composite sound-absorbing material modified by activated clay, which is made of the following raw materials in parts by weight: 115 parts of barite powder, 55 parts of ceramsite, 50 parts of activated clay, 86 parts of styrene-acrylic emulsion, 62 parts of modified tree ash, 18 parts of mica powder, 25 parts of polyimide fiber, 18 parts of nano carbon, 30 parts of EVA, 20 parts of CPE, 8 parts of POM, 6 parts of phthalate, 5 parts of triethyl phosphate, calcium stearate 2 parts, 1.5 parts of zinc stearate.

[0015] Wherein, the modified tree ashes are prepared by the following method: first soak the tree ashes with 15% hydrochloric acid for 3 hours, wash them with deionized water, then soak them with 12% sodium hydroxide solution for 4 hours, and then wash them with deionized water until medium Drying, adding 3% sodium lignosulfonate, 2% methyltriethoxysilane, 2.5% epoxidized triglyceride, 4% ceramic powder equivalent to the weight of tree ash, high speed 1200r / min ...

Abstract

The invention discloses an atlapulgite modified composite sound absorbing material which is prepared from the following raw materials in parts by weight: 100-120 parts of barite powder, 50-60 parts of haydite, 40-50 parts of atlapulgite, 80-90 parts of styrene-acrylic emulsion, 55-65 parts of modified wood ash, 15-20 parts of mica powder, 20-30 parts of polyimide fiber, 10-20 parts of nano carbon, 20-30 parts of EVA (ethylene vinyl-acetate copolymer), 15-20 parts of CPE (chlorinated polyethylene), 5-10 parts of POM (polyoxymethylene), 5-8 parts of phthalate, 4-6 parts of triethyl phosphate, 2-3 parts of calcium stearate and 1-2 parts of zinc stearate. According to the invention, the existing urgent sound absorbing material development problem is solved; and a novel sound absorbing material which meets the requirements, can be adapted to severe environments and has the advantages of high tensile strength, high extension percentage, high breaking strength, good sound absorbing effect and the like can be prepared.

Description

technical field [0001] The invention relates to a composite sound-absorbing material modified by activated clay and a preparation method thereof, belonging to the technical field of material research and production. Background technique [0002] 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. [0003] 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 has insuff...
