[0045] Preparation of epoxy cardanol acetate:
[0046] S1, take by weighing 45.7kg of cardanol sold by Shanghai Aladdin Biochemical Technology Co., Ltd., add 0.4kg of catalyst p-toluenesulfonic acid, stir evenly, add 18.4kg of acetic anhydride under stirring state, stop after stirring reaction at normal temperature for 24h; 5% sodiumbicarbonateaqueous solution and deionized water colloid washed the product three times, the product was washed to neutrality, and then the water was distilled off under reduced pressure to obtain product A42.6kg;
[0047] S2, add 1 kg of formic acid to the product A obtained in step S1 and stir for 20 minutes, then add 4.6 kg of hydrogenperoxide dropwise, the time for the dropwise addition is 1.5 hours, and the temperature of the hydrogenperoxide is maintained at 41°C; 7h, obtain reaction mixture;
[0048] After steps S3 and S2 are completed, the reaction mixture is allowed to stand for stratification, the water layer is removed, and then wash...
[0051] Weigh 10kg of ultrafine nano-active calcium SW-625B and 0.5kg of titanate coupling agent NDZ-201, stir and react at 85°C for 1.5h, and cool to obtain titanate coupling agent-modified calcium carbonate.
Embodiment 1
[0054] A men's shoe, comprising a vamp and a shoe outsole, the vamp is sewn on the shoe outsole, and the shoe outsole is produced by the following method:
[0055] S1, by weighing PVC S-1000 100kg, 40kg of epoxy cardanol acetate prepared by the method of Preparation Example 1, 3kg of diisostearyl malate, 2kg of stearic acid and PVC calcium zinc stabilizer TS- A59 4kg was stirred evenly, and the stirring rate was 1000r / min to obtain a mixture.
[0056] S2, banburying the mixture at 150° C., then extruding and granulating to obtain PVC resin for shoe outsoles.
[0057] In S3, the outsole of the shoe is injected into a mold with PVC resin, heated to 220° C. for a constant temperature reaction for 12 minutes, cooled, and demolded to obtain the outsole of the shoe.

Abstract
The invention relates to the field of shoes, and particularly discloses a shoe outsole. The outsole is prepared from the following raw materials in parts by weight: 100-120 parts of PVC resin; 40-50 parts of epoxycardanol acetate; 3-4 parts of diisostearyl malate; 2-4 parts of a lubricant; and 4-6 parts of a stabilizer. The invention further discloses a pair of male shoes, each male shoe comprises a vamp and a shoe outsole, and the vamps are fixed on the shoe outsoles through gluing or sewing. According to the invention, the epoxycardanol acetate and the diisostearyl malate are used for synergistically plasticizing, so the shoe outsole has better toughness, and the comfort level of the male shoes is improved; the raw material of the epoxycardanol acetate is cardanol, and the cardanol is extracted from natural cashew nut shell oil, belongs to a renewable resource, and is green and environment-friendly. The titanatecoupling agent modified calciumcarbonate is added, so that the compatibility of the titanatecoupling agent modified calciumcarbonate and the diisostearyl malate is good, and the toughness of the shoe outsole is improved.
Description
technical field [0001] This application relates to the field of shoes, more specifically, it relates to a men's shoe and its outsole. Background technique [0002] Outsole materials are usually ethylene-vinyl acetatecopolymer (EVA), polyurethane (PU) and polyvinyl chloride (PVC). [0003] Among them, PVC is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. [0004] Most men have higher requirements for the comfort of the outsole of shoes because they love sports. PVC resin products usually have the defects of high brittleness, poor processability and poor stability. Therefore, the outsole of PVC shoes is generally made of PVC resin with plasticizers, stabilizers and lubricants, etc., extruded and plasticized through screw extrusion in appropriate proportions. The sole PVC resin materia...
