Abstract

The invention provides wear-resistant rubber and a preparation method of the rubber, as well as a double-hardness and double-physical-property rubber sole and a preparation technology of the sole. The wear-resistant rubber can be obtained through the steps of: weighting required materials in proportion, then implementing closed milling, implementing opened milling, implementing vulcanization, and measuring a vulcanization curve. According to the double-hardness and double-physical-property rubber sole, a wearing-prone part of a heel is made from the wear-resistant rubber, while other parts are made from common rubber. The sole can be obtained through the steps of getting the wear-resistant rubber for later use, shaping a wear-resistant block by oil pressure, shaping a big sole, and post-treating. According to the sole produced by the formula and the production technology, the product cost is lowered and simultaneously the requirements of different people are met; and the produced finished product sole is improved in appearance grade and has the effects of good quality, comfort, wear resistance, shock absorbing, and the like.

Description

technical field [0001] The invention belongs to the field of macromolecule chemistry, and in particular relates to the production and preparation of a rubber sole. Background technique [0002] China is currently the world's largest producer and exporter of footwear. The main materials for shoe soles are rubber, PU, ​​PVC, MD, TPR, TPU, EVA, etc. Rubber soles are not easy to slip due to their anti-slip, high elasticity, and good wear resistance. The advantages of fracture, good elongation, and stable shrinkage can be said to occupy half of the footwear products. At present, most of the finished shoes of domestic first-line brands use rubber soles, but the disadvantage of rubber soles is that they use low-cost formula products. The physical properties are unsatisfactory; if high-quality soles are to be made, the cost of the rubber formula used is generally high. [0003] To evaluate whether the performance of the sole is superior, it is mainly evaluated from the aspects of ...
