Problems solved by technology

Due to the use of natural rubber, plastication is required, which consumes manpower and material resources and increases costs
On the other hand, it is difficult to control the acidity and alkalinity of the mixed rubber during the preparation process with carbon black for rubber reinforcement, and it is difficult to meet the requirements of the subsequent vulcanization process.
In order to increase the softness of rubber shoes, a foaming agent is often added to the rubber material, and then the foam holes generated by the use of the foaming agent affect the wear resistance of the shoe, and at the same time make the foam rubber have low tear strength and poor toughness. The degree of adhesion between the foamed compound and the upper surface is reduced

Abstract

The invention relates to a Goodyear type foaming rubber material, which is prepared from a first part and a second part, wherein the first part is prepared from the following raw materials: styrene-butadiene rubber, natural rubber, zinc oxide, octadecanoic acid, N-isopropyl-N'-phenyl p-phenylenediamine, 2,2,4-trimethyl-1,2-dihexahydro quinoline, a reinforcing agent, coumarone resin, short fibers and a foaming agent; the second part comprises sulfur, accelerant dibenzothiazyl disulfide, accelerant CZ and accelerant TMTD added on the basis of the first part. The foamed sole prepared from the rubber material has the advantages of being soft, good in elasticity, good in wear resistance, small in specific gravity and the like, and the foaming rubber material has high sticking degree with the upper.

Description

technical field [0001] The invention belongs to the technical field of foaming outsoles, and in particular relates to a Goodyear foaming rubber material. Background technique [0002] At present, most of the various shoe soles are made of natural rubber as the raw material. After masticating and mixing with other ingredients to make rubber shoe soles, the cost is relatively controllable, and the hardness and other properties can be adjusted according to needs. Basically, People's requests have been met. Since what is used is natural rubber, plastication is required, which consumes manpower and material resources and increases the cost. On the other hand, it is difficult to control the acidity and alkalinity of the mixed rubber during the preparation process with carbon black for rubber reinforcement, and it is difficult to meet the subsequent vulcanization process. In order to increase the softness of rubber shoes, a foaming agent is often added to the rubber material, and...
