Problems solved by technology

Ordinary rubber is heavy, easy to spit frost, not easy to corrode, and not environmentally friendly. TPR thermoplastic rubber has poor anti-slip performance, heavy weight, and easy to turn yellow, while PU polymer polyurethane synthetic material has strong water absorption, easy yellowing, Easy to break, poor elongation, not water resistant, easy to rot

Embodiment

[0018] Natural rubber is 3L standard rubber. Mainly rubber hydrocarbon (polyisoprene), containing a small amount of protein, water, resin acid, sugar and inorganic salts. High elasticity, high elongation strength, excellent tear resistance and electrical insulation, good wear resistance and drought resistance, good processability, easy to bond with other materials, and is superior to most synthetic rubbers in terms of comprehensive performance. The disadvantages are poor oxygen and ozone resistance, easy aging and deterioration; poor oil and solvent resistance, low acid and alkali corrosion resistance; low heat resistance.

[0019] The synthetic rubber is butadiene rubber. Properties of butadiene rubber Because the molecular structure of butadiene rubber is mainly cis-1,4-structure, the molecular arrangement is regular, so its elasticity is better than that of natural rubber. The elasticity of butadiene rubber is the best among general-purpose rubbers. The heat resistance i...

specific Embodiment approach

[0026] The specific embodiment is as follows with the material of parts by weight: natural rubber: 40-60 parts, synthetic rubber: 30-40 parts, SEBS glue: 10-20 parts, synthetic EVA: 10-20 parts, ultra-light white carbon black: 30- 40 parts, naphthenic oil: 6-10 parts, highly active zinc oxide: 3-5 parts, active agent: 3-5 parts, vulcanization accelerator: 2-3 parts, stearic acid: 1-2 parts, diglycoside Alcohol: 2-3 parts, anti-aging agent: 1-3 parts. Among them, natural rubber is 3L standard rubber: synthetic rubber is butadiene rubber and artificial natural rubber IR; SEBS rubber is styrene block copolymer, synthetic EVA is foamed ethylene-vinyl acetate copolymer, and super silica is Super white smoke with strong elasticity.

[0027] Step 1: masticating 40-60 parts by weight of natural rubber on an internal mixer to obtain masticated rubber;

[0028] Step 2: On the basis of step 1, sequentially add 30-40 parts by weight of synthetic rubber, 10-20 parts by weight of SEBS glu...

Abstract

The invention discloses an ultralight high-elastic rubber sole material and a preparation method thereof. The ultralight high-elastic rubber sole material comprises the following raw materials in parts by weight: 40-60 parts of natural rubber, 30-40 parts of synthetic rubber, 10-20 parts of SEBS (Styrene-Butadiene-Styrene Block Copolymer) rubber, 10-20 parts of synthetic EVA (Ethylene Vinyl-Acetate Copolymer), 30-40 parts of ultralight white carbon black, 6-10 parts of naphthenic oil, 3-5 parts of high-activity zinc oxide, 3-5 parts of activating agents, 2-3 parts of vulcanization accelerators, 1-2 parts of stearic acid, 2-3 parts of diethylene glycol and 1-3 parts of anti-aging agents. The preparation method of the ultralight high-elastic rubber sole material comprises four steps. The ultralight high-elastic sole rubber prepared through the method disclosed by the invention has the advantages of scientificity in formula, low cost, simple preparation process and lighter specific gravity of the sole material and effectively enhances the elasticity and bending resistant degree of a sole.

Description

technical field [0001] The invention relates to the field of shoe materials, in particular to an ultra-light and highly elastic rubber sole material and a preparation method thereof. Background technique [0002] At present, the materials used to manufacture shoe outsoles are mainly ordinary rubber, TPR thermoplastic rubber, and PU polymer polyurethane synthetic materials. Ordinary rubber is heavy, easy to spit frost, not easy to corrode, and not environmentally friendly. TPR thermoplastic rubber has poor anti-slip performance, heavy weight, and easy to turn yellow, while PU polymer polyurethane synthetic material has strong water absorption, easy yellowing, Easy to break, poor elongation, not resistant to water, easy to rot. Contents of the invention [0003] The invention provides an ultra-light and highly elastic rubber sole material and a preparation method thereof. The shoe material can be recycled, is ultra-light, highly elastic and wear-resistant. [0004] In orde...
