Problems solved by technology

[0002] The sole is in direct contact with the ground, so the requirements for the material are high, but each material has its advantages and disadvantages, and it is impossible to have resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity and easy Suitable for foot shape, not easy to change shape after setting, heat preservation, easy to absorb moisture, etc.; currently commonly used sole materials include rubber, Oxford, PU, ​​PVC and genuine leather. Natural rubber has anti-skid, no noise, elasticity, good softness, and shrinkage Stable and not easy to break, but the rubber sole is heavy, not wear-resistant, and has a short service life. When walking, the foot bears a heavy load, which is easy to cause fatigue

preparation example Construction

[0022] A preparation method of wear-resistant shoe outsole, comprising the following steps:

[0023] Step 1, prepare the wear-resistant layer: A. First mix and stir the raw materials except glycerol monostearate, methyl propylene glycol, and dicumyl peroxide, and then add glycerol monostearate, methyl propylene glycol, Dicumyl peroxide is mixed evenly, then kneaded by a calender, and formed into rubber granules through kneading, sheeting, extrusion and granulation; B. According to the vulcanization and foaming parameters, the rubber granules are directly molded in the shoe mold Molding, molding temperature 130-140 ℃, molding time 20-30min;

[0024] Step 2, prepare the midsole: first mix ethylene-vinyl acetate copolymer, talc, zinc oxide, bamboo fiber, triethylenediamine, calcium stearate, and ethylenediamine evenly, add azodicarbonamide, hard Fatty acid is rolled with a roll, and then cross-linking agent is added for mixing, and the sheet is cut out, placed in a mold, hot-pre...

Abstract

The invention discloses a wear-resistant shoe outsole and a preparation method thereof. The wear-resistant shoe outsole comprises a wear-resistant layer and an insole compounded on the wear-resistant layer, the wear-resistant layer is prepared from butadiene styrene rubber, natural rubber, brominated butyl rubber, glycerol monostearate, methylpropanediol, dicumyl peroxide, polyethylene glycol, modified glass fibers, polydimethylsiloxane, polyethylene wax, modified bentonite and calcium stearate, and the shoe outsole prepared by the application is good in wear resistance and weather resistance, soft and comfortable, good in wear resistance, good in wear resistance, good in wear resistance, good in wear resistance, good in wear resistance and good in wear resistance. The wear resistance of the shoe outsole is improved by limiting the substructure of the shoe outsole and arranging the wear-resistant layer; and the elastic midsole is arranged to ensure the wearing comfort of the outsole.

Description

technical field [0001] The invention belongs to the field of shoe outsole preparation, and particularly relates to a wear-resistant shoe outsole and a preparation method thereof. Background technique [0002] The sole is in direct contact with the ground, so the material requirements are higher, but each material has its own advantages and disadvantages, it is impossible to have resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy Suitable for foot shape, not easy to deform after setting, heat preservation, easy to absorb moisture and other advantages; currently commonly used sole materials are rubber, oxford, PU, ​​PVC and leather, natural rubber has anti-slip, no noise, elasticity, good softness, shrinkage It is stable and not easy to break, but the rubber sole is heavy, not wear-resistant, and has a short service life. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to ove...
