Abstract

The invention provides light rubber and a preparation method of the light rubber as well as a shoe sole prepared by using the rubber. The rubber is mainly prepared from SBS-I, SBS-II, butadiene styrene rubber, white carbon black, di-(3-triethoxyl silane propyl)-tetrasulfide, stearic acid, PEG 4000, zinc oxide and dicumyl peroxide. The shoe sole produced by using the rubber provided by the invention is light in weight, and the physical indicators meet the national test standard. Meanwhile, the problem on loss of gloss of conventional shoe sole is solved, the brightness of the bright matt finish is enhanced, and the overall effect on appearance is attractive so as to satisfy the demands of different crowds, so that not only is the appearance grade of the product shoe sole produced enhanced, but also the product shoe sole has the characteristics of lightness, comfort and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer chemistry, and in particular relates to a light rubber, its preparation method and application. Background technique [0002] China is currently the world's largest producer and exporter of footwear. The main materials for sole production include rubber, PU, ​​PVC, MD, TPR, TPU, EVA, etc. Rubber soles are known for their anti-skid, high elasticity, good wear resistance, and 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 the formula cost is relatively low. The performance is 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 apparent densit...
