[0002] Shoes are items that are often used in our daily life. At present, the traditional shoe sole manufacturing process has complicated steps and high processing costs, and the foaming effect of the shoe sole material made by the traditional formula is poor, which is not suitable for actual production and application. Therefore, it needs a Only the formulation and preparation process of an ultra-light one-shot composite shoe sole can solve these problems

[0032] A preparation process for an ultra-light one-shot composite shoe sole, comprising the following steps:
[0033] (1) Premixing: first mix plastic styrene-butadiene rubber 60%; styrene thermoplastic elastomer 5%; ethylene-vinyl acetate copolymer 8%; polystyrene 10%; stearic acid 0.5%; zinc stearate 0.5% ; Pour into the internal mixer in proportion;
[0034] (2) Banburying: add 10% naphthenic oil for premixing banburying. Mixing for 20 minutes, turning the material twice in the middle, turning the material for the first time for 10 minutes, and turning the material for the second time in 15 minutes;
[0035] (3) After banburying, pour it into the conveying hopper into the granulator bucket and start the granulator for granulation;
[0036] (4) Sprinkle evenly a mixt...

Abstract
The invention discloses a formula and a preparation technology of an ultralight once-moulded composite sole. Through use of thermoplastic styrene-butadiene rubber, which particularly refers to thermoplastic styrene-butadiene rubber 1475 and thermoplastic styrene-butadiene rubber 3411, a styrenic thermoplastic elastomer and ethylene-vinyl acetate copolymer as raw materials, not only is the cost reduced, but also the tensile strength of a material is improved, so that the material has small deformation and good flexibility and resilience; the oil content of the formula and other performance areextended; in addition, the viscosity is reduced during mixing, so that the blending operation of a mixture is facilitated; the folding resistance of a product is improved; by the preparation technology, a single-color or multi-color composite sole can be moulded once and additional manual pasting is not required; the ultralight once-moulded composite sole produced according to the formula is lightin weight, comfortable, wearable and low in cost.
Description
technical field [0001] The invention relates to the field of shoe sole materials, in particular to a formula and a preparation process of an ultra-light one-shot composite shoe sole. Background technique [0002] Shoes are items that are often used in our daily life. At present, the traditional shoe sole manufacturing process has complicated steps and high processing costs, and the foaming effect of the shoe sole material made by the traditional formula is poor, which is not suitable for actual production and application. Therefore, it needs a These problems can only be solved by a formula and a preparation process of an ultralight one-shot composite shoe sole. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a formula and preparation process of an ultra-light one-shot composite shoe sole. [0004] The technical solution adopted by the present invention is: a formula for an ultra-light one-shot composit...
