Embodiment 1

[0026] A water-resistant SBS foamed shoe sole material, made of the following components in parts by weight: 36 parts of SBS, 1.5 parts of AC foaming agent, 14 parts of naphthenic oil, 1.5 parts of magnesium stearate, 2 parts of DCP, rare earth stabilized 1.8 parts of agent, 0.3 parts of triphenyl phosphite, 0.6 parts of antioxidant GM, 15 parts of boron carbide fiber, 8.5 parts of PPSS, and 6 parts of SBS-g-MAH.

[0027] The steps of its preparation method are as follows:

[0028] (1) Extract boron carbide fibers with ethanol for 40 hours to remove surface impurities, wash with deionized water after extraction, add nitric acid after drying and stir at 90°C for 3 hours, take it out and wash with deionized water to obtain Oxidized boron carbide fibers;

[0029] (2) Add the oxidized boron carbide fiber obtained in step (1) into a rare earth solution with a mass fraction of 0.4%, take it out after soaking at room temperature for 5 hours, and place it in a vacuum drying oven at 9...

Embodiment 2

[0032] A water-resistant SBS foaming shoe sole material is made of the following components in parts by weight: 50 parts of SBS, 1.8 parts of AC foaming agent, 11 parts of naphthenic oil, 2.5 parts of calcium stearate, 1.5 parts of DCP, Rare earth stabilizer 1.4 parts, triphenyl phosphite 0.4 parts, antioxidant GM 0.8 parts, boron carbide fiber 14 parts, PPSS 8 parts, SBS-g-MAH 10 parts.

[0033] Its preparation method is the same as Example 1.

Description

Technical field: [0001] The invention relates to a shoe sole material, in particular to a water-resistant SBS foamed shoe sole material and a preparation method thereof. Background technique: [0002] SBS is a thermoplastic elastomer prepared by anionic polymerization of styrene and butadiene with alkyllithium as a catalyst. Compared with other thermoplastic elastomers, SBS has the characteristics of high strength, softness, and small permanent deformation. Rubber elasticity, suitable for adhesives and sealing materials for hot-melt processing, in the shoe industry, polymer modification, asphalt modification, waterproof coatings, liquid sealing materials, wires, cables, automotive parts, medical equipment parts, household appliances, It has a wide range of applications in office automation and adhesives, and has broad prospects for development and utilization. At present, my country's SBS products are mainly used in shoemaking, asphalt modification, polymer modification and...
