Abstract

The invention provides a method for preparing an anti-mosquito EVA (Ethylene-Vinyl Acetate copolymer) shoe sole material. The method comprises the following steps: (1) crushing lemon grass by a crusher so as to prepare lemon grass powder, adding the lemon grass powder into a supercritical CO2 extraction pool for extracting so as to obtain extract liquor, carrying out re-extraction by using diethyl ether, taking out a diethyl ether layer, and then, carrying out drying, so as to obtain a lemon grass extract for later use; (2) carrying out ball-milling on apatite, adding apatite powder and the lemon grass extract into a stirrer, carrying out stirring at room temperature so as to obtain a lemon grass-apatite mixture, adding the lemon grass-apatite mixture into an ethanol solution, carrying out uniform stirring, then, adding a coupling agent into the solution for ultrasonic dispersion, transferring the dispersion solution into a constant-temperature water bath, carrying out stirring, carrying out discharging, then, carrying out suction filtration and washing, and carrying out drying, so as to obtain a modified lemon grass-apatite mixture for later use; (3) pouring EVA, zinc white, stearic acid and the modified lemon grass-apatite mixture into a Banbury mixer for first-stage mixing, adding diisopropylbenzene hyperoxide and azobisformamide into the Banbury mixer for second-stage mixing, then, carrying out roll mixing and granulating so as to obtain granules, carrying out injection molding, and carrying out baking, thereby obtaining the anti-mosquito EVA shoe sole material. The shoe sole material prepared by the method has a very good anti-mosquito function.

Description

Technical field: [0001] The invention relates to a shoe sole material, in particular to a preparation method of an anti-mosquito EVA shoe sole material. Background technique: [0002] Shoe material is the main application field of EVA resin in my country. In the EVA resin used in shoe material, the content of vinyl acetate is generally 15% to 22%. Compared with polyethylene, due to the introduction of vinyl acetate monomer in the molecular chain, EVA reduces high crystallinity, improves flexibility, impact resistance, filler compatibility and heat sealing performance, and also has good cushioning and shock resistance. , Moisture-proof, anti-chemical corrosion, non-toxic, non-absorbent and other advantages, it is widely used in the soles and interior materials of middle and high-end travel shoes, hiking shoes, slippers, sandals. In addition, this material is also used in the field of sound insulation panels, gym mats and sealing materials. Shunde and Zhongshan in Guangdong,...
