Problems solved by technology

[0004] ① Reduce the content of neoprene in the rubber formula, which satisfies the manufacturability to a certain extent, but sacrifices the index of rubber oil resistance; ② Increase the content of neoprene in the rubber formula, so that the designed vulcanized rubber has wear resistance The processing technology has great defects; ③The proportion of neoprene in the rubber formula is moderate. Although the physical and chemical properties of the prepared product can meet the standards, the Mooney viscosity of the rubber material is high, and the production and molding process of the compounded rubber is not good.
[0005] The Chinese invention patent with the notification number CN 102964640A discloses a "rubber welt for rubber double-density shoes and its preparation method", which uses natural rubber with good manufacturability and neoprene with good adhesion as the main material , supplemented with a certain proportion of tackifier and soft carbon black, designed to imp

Example Embodiment

[0080] Example 1 Oil-resistant and wear-resistant dual-density footwear rubber outsole and preparation method thereof

[0081] This embodiment provides an oil-resistant, wear-resistant dual-density footwear rubber outsole and a preparation method thereof. The specific preparation process is carried out in sequence according to the following steps:

[0082] (11) Rubber mastication

[0083] Put 30kg of natural rubber (model SCRWF) into an open mill or internal mixer for plastic smelting. After the plasticity reaches 0.45-0.50, the natural rubber A1 with plasticity meeting the requirements is obtained;

[0084] (12) Compounding of rubber

[0085] Put neoprene (20kg neoprene CR322 A, 18kg neoprene CR232 ) And 33 kg of butadiene rubber (model BR9000), respectively, after being thinned and broken, and then put into an open mill or internal mixer together with A1 for mixing. After mixing until the cross section of the plasticized rubber is uniform, flat and smooth, C1 is obtained;

Abstract

The invention discloses an oil-resistant and abrasion-resistant dual-density shoe rubber outsole. Original ingredients are in reasonable compatibility, natural rubber, butadiene rubber and chloroprene rubber serve as main materials and are matched with other accessory ingredients capable of achieving good co-vulcanization of the natural rubber and the chloroprene rubber, and the advantage of considering manufacturability and physical and chemical properties of vulcanized rubber is achieved. The invention further provides a preparation method of the rubber outsole. The method includes the steps of rubber plastifying, sizing material co-smelting, sizing material banburying, sizing material mixing, manufacturing of the rubber outsole and the like in sequence. The method is simple, the process is easy to control, and the prepared shoe outsole is moderate in hardness and good in durability and abrasion resistance. The preparation method is suitable for preparation of shoe rubber outsoles, rubber tubes, sealing rings and other rubber objects.

Description

technical field [0001] The invention belongs to the field of rubber manufacturing, and relates to shoe rubber and a preparation method thereof, in particular to an oil-resistant and wear-resistant double-density shoe rubber outsole and a preparation method thereof. Background technique [0002] Rubber double-density shoes and boots have the advantages of light weight, light wearing, good cushioning elasticity, etc., and have been favored by consumers in the market. For rubber dual-density footwear, the ingredients and production of the rubber sole are crucial. At present, most of the rubber soles are oil-resistant rubber. Neoprene or nitrile rubber is generally used as the main material for oil-resistant rubber. For the former, some sulfides are contained in the raw rubber as regulators. There are differences in rubber types, so it is difficult to design neoprene and natural rubber blended rubber. Even if it is designed, either the rubber processing technology is not good, ...
