Abstract

The invention discloses a preparation method of a wear-resistant SBS sole material, and belongs to the field of high polymer materials. The preparation method comprises the following steps of: 1) in the presence of a catalyst, modifying nano SiO2 at room temperature by using a silane coupling agent; 2) banburying and mixing 1-10 parts of modified nano SiO2, a small amount of SBS (85-90 parts in total), 3-8 parts of white oil and 0.5-1 part of an antioxidant to prepare a pretreated master batch; and 3) mixing the pretreated master batch, 1-3 parts of an anti-aging agent and the rest SBS, and extruding and granulating to obtain the wear-resistant SBS sole material (all the components are calculated by weight). The wear-resistant sole material disclosed by the invention has the characteristics of excellent wear resistance and high breaking strength.

Description

technical field [0001] The invention relates to a preparation method of a wear-resistant SBS shoe sole material, which belongs to the field of polymer materials. Background technique [0002] With the rapid development of economy and society, people's living standards continue to improve, and there are higher requirements for the comfort, safety and wear life of shoes. [0003] As a shoe sole material, SBS can be used to produce various grades of leather shoes, travel shoes, and children's shoes. The advantage of being recyclable. However, when SBS is used alone as a sole material, there is a shortcoming of insufficient wear resistance. Although the softness of the material can be improved by adding softening oil or blending an elastic material with better compatibility, the tensile strength and wear resistance of the material will decrease. The two most important indicators of sole materials are softness and wear resistance. Softness and wear resistance are a pair of con...
