Problems solved by technology
[0003] 1. The cost is relatively expensive, and the cost is generally more than 100 yuan / kg;
[0004] 2. Most of them are made of saturated rubber such as hydrogenated nitrile rubber, butyl rubber and other materials, which increases the difficulty of bonding the sole and the upper surface
[0005] 3. In the prior art, carbon black, white carbon black, calcium carbonate, clay and other materials are mainly used as reinforcing agents and fillers for shoe soles, but these materials cannot guarantee the high temperature resistance requirements of rubber products
In the prior art, methacrylate is mainly used in some engineering products, but it has not been found to be used in the preparation of shoe soles

Abstract
The invention discloses a sizing material for a high-temperature-resisting rubber sole and a preparation process thereof. The sizing material is prepared and produced by utilizing unsaturated rubber material-butadiene-acrylonitrile rubber, methylacrylate and an optimized effective vulcanization system to be effectively combined and carrying out procedures of mixing, open milling and the like. When the high-temperature-resisting rubber sole is machined, the sizing material disclosed by the invention is utilized, so that on the one hand, the production cost is reduced; and on the other hand, the strength and the stability of bonding a sole and an upper are improved. The sizing material disclosed by the invention is applicable to preparing the high-temperature-resisting rubber sole including a fire-fighting boot sole, a high-temperature work sole and the like.
Description
technical field [0001] The invention belongs to the technical field of shoemaking, and in particular relates to a rubber material for high-temperature-resistant rubber soles and a preparation process thereof. Background technique [0002] At present, most of the existing high-temperature-resistant rubber soles are products that can withstand high temperatures above 250°C. The rubber materials used are generally high-saturated hydrogenated nitrile rubber as the main raw material, dicumyl peroxide vulcanization system, carbon black or white Carbon black, etc. are reinforcing or filling systems, and esters are softening systems. The high temperature resistance of rubber soles can be improved through the high temperature resistance of hydrogenated nitrile rubber itself and the vulcanization system of dicumyl peroxide. But existing high temperature resistant rubber sole formula and preparation process mainly have the following problems: [0003] 1. The cost is relatively expensi...
