Embodiment Construction
[0015] A PET fiber / glass fiber composite sound-absorbing cotton, made of the following raw materials in parts by weight: PET fiber 75, quartz glass fiber 48, fatty alcohol polyoxyethylene ether sodium sulfate 16, Pingpingjia O-10 25, PP 95, LDPE 32. Calcium carbonate whisker 16, modified diatomaceous earth 12, stearic acid 2.5, trioctyl trimellitate 6, ammonium polyphosphate 5, oxidized polyethylene wax 3, bis(dioctyloxypyrophosphate) ) Ethylene titanate 1.5, zinc stearate 2, isooctyl tin dimethyldithioglycolate 2, antioxidant RD 0.8, antioxidant 1010 1.5.
[0016] Wherein, the modified diatomite is prepared by the following method: put the dried diatomite into a ball mill, add 25% graphite, 2% vermiculite powder, 2% sepiolite powder, 5% light Calcium carbonate, 2.5% water glass and 4% polyvinyl alcohol, ball milled for 10 hours, calcined at 1100°C for 2 hours, crushed and ground into 200 mesh powder.
[0017] The preparation method of PET fiber / glass fiber comp...

Abstract
The invention discloses PET (Polyethyleneglycol Terephthalate) fiber / glass fiber composite sound absorbing cotton, which is prepared from the following raw materials in parts by weight: 70-80 parts of PET fiber, 40-50 parts of quartz glass, 15-20 parts of fatty alcohol polyoxyethylene ether sodium sulfate, 20-30 parts of peregal O-10, 80-100 parts of PP (Polypropylene), 30-40 parts of LDPE (Low-Density Polyethylene), 15-20 parts of calcium carbonate whiskers, 10-15 parts of modified diatomite, 2-3 parts of stearic acid, 5-8 parts of trioctyl trimellitate, 4-6 parts of ammonium polyphosphate, 2-3 parts of oxidized polyethlene wax, 1-2 parts of di(dioctyloxy pyrophosphate)ethylene titanium ester, 2-3 parts of zinc stearate, 1-2 parts of dimethyldimercaptoisooctylacetate tin, 0.5-1.5 parts of anti-aging agent RD, and 1-2 parts of antioxidant 1010. The sound absorbing cotton prepared in the invention has the advantages of high appearance flatness, uniform thickness, soft handfeel, high product viscosity, high tensile property, high sound absorbing performance, good flame retarding effect and the like.
Description
technical field [0001] The invention relates to nonwoven fabric technology, in particular to a PET fiber / glass fiber composite sound-absorbing cotton and a preparation method thereof. Background technique [0002] Noise is one of the three major public hazards that pollute the environment in modern society. Noise directly affects people's health. With the progress of society, people put forward higher and higher requirements for the prevention and control of noise that pollutes the environment. Sound-absorbing cotton can convert the vibration energy of medium and high-frequency noise generated in life into the kinetic energy of the fine denier fibers inside the sound-absorbing cotton, and convert it into heat energy and disappear, achieving the function of sound absorption and noise reduction. Therefore, sound-absorbing cotton has good sound-absorbing, heat-insulating and warm-keeping properties, and has been widely used in the fields of building materials, automobiles and o...
