Description
Technical field
The present invention relates to composite sound-absorbing material of a kind of atlapulgite modification and preparation method thereof, belong to investigation of materials and production technical field.
Background technology
Along with the development of industrial production, communications and transportation, urban architecture, and the increase of the density of population, the increasing of home amenity (sound equipment, air-conditioning, televisor etc.), neighbourhood noise is day by day serious, and it has become large public hazards of polluting the human society environment.Noise not only can affect hearing, but also people's cardiovascular systems, neural system, endocrine system had a negative impact.
Existing sound absorbent material also has compound, but the compound performance index excellence of inorganic material and organic materials is less.See on the whole, China's sound absorbent material industry product working ability is not enough, in the research and development of high-end sound absorbent material with produce and exist larger gap compared with developed countries, as: all kinds vehicles (passenger vehicle, subway, high ferro), especially in recent years the demand of the sound absorbent material such as manned spacecraft, also lack with the market-construction industry of product maximum and to be connected, lack market awareness and building products working ability.Therefore, be badly in need of at present that research and development are a kind of can to stand the harsh and unforgiving environments test, have the tensile strength height, elongation is high, breaking tenacity is high, sound-absorbing effect good and the sound-absorbing material of the advantage such as low cost of manufacture.
Summary of the invention
The object of the invention is to, composite sound-absorbing material of a kind of atlapulgite modification and preparation method thereof is provided, solves the prescription of matrix material, reduce the production cost that adopts single kind or plurality of raw materials, improve simultaneously the tensile strength of sound-absorbing effect and the material of material, elongation, breaking tenacity.Be used for the spray silk and make acoustical cotton.
The technical solution used in the present invention is as follows:
A kind of composite sound-absorbing material of atlapulgite modification, its raw material by following weight part is made: ground barium sulfate 100-120, haydite 50-60, atlapulgite 40-50, benzene emulsion 80-90, modification trees ashes 55-65, mica powder 15-20, polyimide fiber 20-30, nano-sized carbon 10-20, EVA 20-30, CPE 15-20, POM 5-10, phthalic ester 5-8, triethyl phosphate 4-6, calcium stearate 2-3, Zinic stearas 1-2.
Described modification trees ashes are made by following methods: use first 10-15% salt acid soak trees ashes 3-4h, deionized water wash is clean, soak 3-4h with the 10-12% sodium hydroxide solution again, extremely neutral with deionized water wash again, oven dry, add and be equivalent to the sodium lignosulfonate of trees ashes weight 2-3%, the Union carbide A-162 of 1-2%, the epoxidation tri-glyceride of 2-3%, the ceramics powder of 3-5%, high speed 1200-1500r/min stirs 20-30min, and the ovendry power breakdown mill becomes ultrafine powder to get final product.
The composite sound-absorbing material preparation method of atlapulgite modification may further comprise the steps:
(1) ground barium sulfate, haydite, atlapulgite is dry except moisture respectively, drying temperature is 110-120 ℃, be 2-3h time of drying, by pressing afterwards formulation ratio ground barium sulfate, haydite, atlapulgite, mica powder, benzene emulsion are added in the high-speed mixer, speed with 500-800rpm under 150-160 ℃ mixes 3-5min, add modification trees ashes again and continue blend 5-8min, it is stand-by that material is cooled to normal temperature;
(2) EVA, POM, CPE, phthalic ester, triethyl phosphate, calcium stearate, Zinic stearas being added Mixers with Multi-direction Movement carries out just mixed, just mixed 4-6min, then enter high-speed mixer, add nano-sized carbon, polyimide fiber, speed with 1500-2000rpm under 105-110 ℃ stirs 2-5min, and it is stand-by that material is cooled to normal temperature;
(3) material that above-mentioned steps (1) and step (2) is made adds twin screw mixings forcing machine to be processed, and requires 180-280 ℃ of Temperature Setting scope according to product index, then with the material input granulator granulation of extruding, namely gets the composite sound-absorbing material.
Beneficial effect of the present invention is as follows:
The present invention passes through formula adjustment and process modification, utilize modification trees ashes to coat the inorganic powders such as atlapulgite, ground barium sulfate, thereby improve sound-absorbing effect and the intensity of sound absorbent material, solved well the contradiction that sound absorbent material intensity and sound absorption qualities can not get both.The invention solves the research and development problem of present anxious sound absorbent material, produced the harsh and unforgiving environments that can stand that satisfies the demands and tested, have the sound-absorbing material of the advantages such as tensile strength height, elongation is high, breaking tenacity is high, sound-absorbing effect is good.Owing to adopted the inorganic material of larger proportion, therefore reduced production cost, because the intensity of inorganic material is higher, improved the mechanical property of material simultaneously.
