The rubber shoe outsole is in direct contact with the ground during the wearing of rubber shoes, which requires frequent friction, compression and bending, and requires good wear resistance, flexure resistance, elasticity and a certain strength, and requires the rubber to be soft, small shrinkage and good viscosity, and is processed with natural rubber, styrene-butadiene rubber, butadiene rubber and its combined rubber as raw materials. As a low-cost raw material to replace natural rubber, latex reclaimed rubber has the characteristics of high strength, good elasticity and small specific gravity, which can replace some natural rubber and butadiene rubber to produce rubber shoe outsole and reduce costs.

2. Latex reclaimed rubber produces dark green rubber shoes outsole vulcanization formula
55 parts of natural rubber, 7 parts of styrene-butadiene rubber, 7 parts of butadiene rubber, 31 parts of latex reclaimed rubber; 3.5 parts zinc oxide, 2.1 parts stearic acid, 1 part antioxidant SP-C, 20 parts of light calcium carbonate, 35 parts of clay, 13 parts of lithopone powder, 0.2 parts of phthalocyanine green, 3.6 parts of industrial lipid, 0.4 parts of accelerator M, 0.5 parts of accelerator D, 0.6 parts of accelerator DM, 1.8 parts of sulfur, 0.2 parts of salicylic acid; Total 181.9 copies.
3. Latex reclaimed rubber produces yellow rubber shoes outsole vulcanization formula
55 parts of natural rubber, 25 parts of butadiene rubber, 20 parts of latex reclaimed rubber, 4 parts of zinc oxide, 1.6 parts of stearic acid, 0.5 parts of antioxidant MB, 30 parts of light calcium, 12.5 parts of silica, 33 parts of ultrafine calcium carbonate, 25 parts of lithopone powder, 4 parts of engine oil, 4 parts of coumarone resin, 0.16 parts of benzidine yellow, 1.34 parts of accelerator M, 0.65 parts of accelerator D, 1.65 parts of sulfur; Total 218.4.
4. Latex reclaimed rubber production of different colors of rubber shoes outsole formula design
(1) Selection of reclaimed rubber
When using latex reclaimed rubber instead of natural rubber and butadiene rubber to produce light-colored and colored rubber shoe outsoles, it is recommended to choose white latex reclaimed rubber or color latex reclaimed rubber of suitable color (red latex reclaimed rubber, green latex reclaimed rubber, etc.); Among them, white natural reclaimed rubber is light in color, easy to match color, and not easy to change color. When using latex reclaimed rubber to produce black rubber outsole, choose black latex reclaimed rubber, which is cheaper and can show good performance in dark rubber products.
(2) Latex reclaimed rubber production of light-colored rubber shoes outsole compounding agent selection
When using latex reclaimed rubber to produce light-colored and colored rubber outsoles, it is recommended to use light-colored compounding agents and non-polluting compounding agents, and light-colored reinforcing agents and fillers such as silica, activated calcium carbonate and clay are used in the reinforcing filling system; non-polluting petroleum-E4LYY815 softeners such as paraffin oil, naphthenic oil, and petroleum jelly in the softening plasticizing system; The anti-aging system selects non-polluting antioxidants such as MB, SP, and 246; An appropriate amount of titanium dioxide to improve the color vividness, color rubber outsole needs to choose strong tinting strength, bright color, no migration, high temperature resistance colorants, such as chrome yellow, iron oxide red, rubber red, etc.
(3) Latex reclaimed rubber production of black rubber shoes outsole compounding agent selection
When mixing latex reclaimed rubber to produce black rubber shoe outsoles, carbon black can be used to reinforce, such as high wear-resistant carbon black and groove carbon black, to improve the wear resistance and tear resistance of the rubber material; Softeners such as coumarone resin, engine oil, and petroleum jelly can be used as softeners; Antioxidant D, 4010, etc. can effectively improve the aging resistance of black rubber shoe outsoles.
When using latex reclaimed rubber to reduce the production cost of rubber outsole, we must choose the right natural reclaimed rubber products, reasonably design the rubber outsole formula containing reclaimed rubber, and reduce more raw material costs under the premise of ensuring the performance of the sole.
