The invention discloses a preparation method of a non-woven fabric, and belongs to the field of spinning. Sodium pyrophosphate, glucose, sodium hydroxide, ferrous sulfate and water are sampled, nitrogen protection is adopted, heating and stirring are performed, and then cumyl hydroperoxide and polybutadiene are added and stirred and mixed; a stirring mixture, allyl benzene, methyl methacrylate, epoxypropyl methacrylate and dibenzyl phthalate are obtained to be added into magnesium sulfate, stirring, mixing and drying are performed, a drying object is obtained to be added into polylactic acid to be mixed, and a mixed matrix is obtained; folium eriohotryae and aloe are obtained to be mixed and homogenized, deionized water is added for digestion and suction filtration, a filtrate is obtainedfor centrifuging, a supernate is obtained to be added into a copper nitrate solution to be mixed, and an antibiotic finish solution is obtained; processed linen fiber, a dispersing solution and the antibiotic finish solution are obtained to be soaked and filtered, the linen fiber is taken to be cleaned with deionized water, and linen fiber is obtained; linen fiber, the mixed matrix, polypropyleneand sodium alginate are obtained to be mixed for opening, carding and lapping, the mixture is placed into a needle machine for needling treatment, and hot rolling is performed to obtain the non-wovenfabric.

The invention discloses isotactic polypropylene/tall oil acid/polybutadiene composite sound absorbing cotton and a preparation method thereof. The composite sound absorbing cotton is formed by a top face layer, a back face layer and a cellucotton layer arranged between the top face layer and the back face layer. The top face layer and the back face layer are made of a non-woven fabric material. The composite sound absorbing cotton is characterized in that the non-woven fabrics are prepared by the following raw materials by weight through a melt-blow method: 100 parts of isotactic polypropylene, 1-2 parts of tall oil acid, 8-10 parts of polybutadiene, 5-7 parts of solid paraffin, 1-2 parts of barium stearate, 2-3 parts of aluminium hydroxide, 14-17 parts of diethylene glycol dibenzoate, 1-2 parts of zinc borate, 12-14 parts of dry shells, 7-9 parts of basalt, 3-5 parts of apocynum venetum, 2-4 parts of white peony roots, 1-2 parts of bighead atractylodes rhizome and 4-5 parts of auxiliary. The isotactic polypropylene/tall oil acid/polybutadiene composite sound absorbing cotton has the advantages of being high in tensile property, large in product void rate and good in breathability, and improves the sound absorbing effect of ordinary sound absorbing cotton.

The invention discloses a high-temperature-resistant thermoplastic elastomer and a preparation method thereof. The high-temperature-resistant thermoplastic elastomer is prepared from the following raw materials in parts by weight: 15-25 parts of cis-1,4-polybutadiene rubber, 20-25 parts of acrylate rubber, 5-7 parts of bisphenol A novolac epoxy resin, 10-12 parts of diphenylmethane bismaleimide, 8-12 parts of polyethylene, 5-8 parts of paraffin oil, 3-5 parts of polyethyleneglycol, 4-6 parts of dibasic lead phosphite, 4-6 parts of N,N-diacetyladipyldiamido hydrazine, 1-4 parts of dibutyltin dilaurate, 1-5 parts of citric acid, 3-6 parts of calcium carbonate, 2-4 parts of mullite powder, 8-15 parts of fly ash and 10-15 parts of modified composite filler. The high-temperature-resistant thermoplastic elastomer has the advantages of excellent aging resistance, excellent high-temperature resistance, favorable flame-retardant effect and high oxygen index (up to 33% or above), and can be used in a high-temperature environment for a long time without the phenomena of cracking, bending, shrinkage and the like.
