Problems solved by technology

SBS composite materials can be used as shoe sole materials, but their strength and wear resistance are still not up to the requirements of use. In the industry, inorganic reinforcing phases are often filled to improve their performance, but the surface of the inorganic filling phase is hydrophilic and oleophobic, and its specific surface energy is low. Large, easy to agglomerate between particles, making it difficult to disperse uniformly in the organic matrix and weak binding force with the matrix, resulting in poor strength of the material, especially unsatisfactory wear resistance

Abstract

The invention discloses a preparation method of a wear-resistant SBS (styrene butadiene styrene) sole material. The preparation method comprises the following steps: step 1, calcium carbonate, maleic anhydride, ethylene glycol and water are mixed, and modified calcium carbonate is obtained; step 2, modified calcium carbonate, neodymium oxide, strontium carbonate, alumina, magnesium oxide and absolute ethyl alcohol are mixed uniformly and sintered, and a first mixture is obtained; step 3, polyethylene glycol is added to the first mixture, the materials are sintered, and a second mixture is obtained; step 4, ethylene glycol, water, linoleic acid, sodium dodecylbenzenesulphonate, styrene and potassium sulfate are added to the second mixture for a reaction, and a third mixture is obtained; step 5, SBS, the third mixture, polystyrene, UHMWPE (ultrahigh molecular weight polyethylene), carbon black, terpene resin, lanthanum oxide, cerium oxide, zirconia, PEEK (polyether-ether-ketone) resin, oxidized polyethylene wax, macadimia nut shell powder, snail shell powder and bamboo fibers are uniformly mixed and subjected to milling, and the wear-resistant SBS sole material is obtained. The SBS sole material has the advantages of high strength and good wear resistance.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a preparation method of a wear-resistant SBS shoe sole material. Background technique [0002] Styrene-butadiene-styrene block copolymer (SBS) is a tri-block copolymer of styrene and butadiene as monomers, which has the characteristics of plastic and rubber, and is called "third-generation synthetic rubber". Similar to styrene-butadiene rubber, SBS can be in contact with water, weak acid, alkali, etc. It has excellent tensile strength, large surface friction coefficient, good low-temperature performance, and good processing performance. It has become the most consumed thermoplastic elastomer at present. SBS composite materials can be used as shoe sole materials, but their strength and wear resistance are still not up to the requirements of use. In the industry, inorganic reinforcing phases are often filled to improve their performance, but the surface of the inorgani...
