Embodiment 1

[0030] Foam composite rubber sole material, by weight, is made of the following components: 55 parts of butadiene rubber, 3.3 parts of DCP, 6 parts of white oil, 4 parts of AC foaming agent, 6 parts of dioctyl sebacate , 4 parts of chlorinated paraffin, 0.5 parts of anti-aging agent IPPD, 1.5 parts of accelerator DPTT, 2.5 parts of diethylene glycol, 12 parts of EVA, 4 parts of zinc oxide, 2 parts of stearic acid, 25 parts of modified dolomite powder .

[0031] The preparation method of this foam composite rubber sole material is:

[0032] (1) Dolomite is added in the sodium dithionite solution of 16% concentration of 3 times of weight, filter after stirring for 2 hours, wash the filter cake repeatedly with distilled water, obtain bleached dolomite after drying;

[0033] (2) Pass the bleached dolomite obtained in step (1) through a 100 mesh sieve to obtain dolomite micropowder, add the dolomite micropowder and distilled water with a weight ratio of 1:10 together in the agate ...

Abstract

The invention provides a foamed composite rubber shoe sole material which is prepared from the following components: 50 to 63 parts of butadiene rubber, 3 to 5 parts of a vulcanizing agent, 6 to 11 parts of a softening agent, 3 to 4 parts of a foaming agent, 5 to 10 parts of a plasticizer, 2 to 5 parts of a lubricating agent, 0.5 to 1 parts of an anti-aging agent, 1 to 3 parts of a promoting agent, 2 to 4 parts of an activating agent, 12 parts of EVA, 4 parts of zinc oxide, 2 parts of stearic acid and 20 to 25 parts of modified dolomite powder. The invention further provides a preparation method of the foamed composite rubber shoe sole material. The foamed composite rubber shoe sole material provided by the invention is better in tear strength and tensile strength and higher in flame retardancy.

Description

Technical field: [0001] The invention relates to a shoe sole material, in particular to a foamed composite rubber shoe sole material and a preparation method thereof. Background technique: [0002] Butadiene rubber is the abbreviation of cis-1,4-polybutadiene rubber, and its molecular formula is (C4H6)n. Butadiene rubber is a synthetic rubber with regular structure polymerized by butadiene, and its cis structure content Above 95%. According to different catalysts, it can be divided into nickel-based, cobalt-based, titanium-based and rare earth-based (Nd-based) butadiene rubber. Butadiene rubber is the second largest synthetic rubber after styrene-butadiene rubber. Compared with natural rubber and styrene-butadiene rubber, it has excellent cold resistance, wear resistance and elasticity after vulcanization, less heat generation under dynamic load, and good aging resistance. It is easy to use with natural rubber, neoprene or nitrile rubber. Butadiene rubber is especially su...
