Problems solved by technology

[0002] Due to its unique physical and chemical properties, rubber products do not have breathable properties; thus people feel uncomfortable when using them
For example, full rubber shoes worn in rainy days, or rubber boots used for leisure fishing and hunting, or safety rubber shoes worn for labor protection, etc., due to the lack of breathability, people have many uncomfortable problems such as stuffy, hot, and damp when wearing them. Feeling; wearing it for a long time is also easy to breed bacteria and emit odor, which is not conducive to the protection of human feet

Abstract

The invention relates to a rubber material and a rubber material product. The invention aims to provide the rubber with permeability, so as to promote updating and upgrading of products in various industries. The invention adopts the technical proposal that the permeable rubber has the compositions of general rubber. The invention is characterized in that the compositions in weight portion of the permeable rubber are 40 to 65 portions of natural rubber, 0.5 to 60 portions of polyethylene oxide, 6 to 9 portions of butadiene-styrene rubber, 1 to 3 portions of sulfur, 1 to 1.5 portions of accelerant, 2 to 4 portions of zinc carbonate, 0.2 to 0.4 portion of stearic acid, 8 to 12 portions of white carbonic acid, 1.2 to 1.4 portions of antiaging agent and 1.3 to 1.7 portions of homogenizing agent. The permeable rubber can be used for manufacturing footwear materials and mackintoshes.

Description

technical field [0001] The invention relates to a rubber material and its products, especially the rubber with air permeability and its products. Background technique [0002] Due to its unique physical and chemical properties, rubber products do not have breathable properties; thus people feel uncomfortable when using them. For example, full rubber shoes worn in rainy days, or rubber boots used for leisure fishing and hunting, or safety rubber shoes worn for labor protection, etc., due to the lack of breathability, people have many uncomfortable problems such as stuffy, hot, and damp when wearing them. Feeling; wearing it for a long time is also easy to breed bacteria and emit odor, which is not conducive to the protection of human feet. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiencies in the prior art, provide a kind of improvement of rubber, this kind of rubber should have breathability, to promote the ...
