Problems solved by technology

However, inorganic materials such as antimony trioxide and aluminum hydroxide are used as flame retardants. Due to their limited flame retardant ability, they need to be used in large quantities in the formula, which leads to a significant decline in the physical properties of the rubber and the formation of abnormal quality problems such as rubber blooming. Rubber shoes are not durable, have a lot of three wastes, are not environmentally friendly, have little use value, and have low application breadth

Abstract

The invention discloses a wear-resistant flame-retardant sole rubber for forest fire-fighting shoes. According to the present invention, natural rubber, butadiene-styrene rubber and cis-1,4-polybutadiene rubber are used as main materials, the physical properties of the rubber material are ensured by adding a reinforcing filler and a softener, the service life of the rubber sole is ensured, and theexcellent flame retardancy is provided for the product by adopting efficient flame retardants decabromodiphenyl ether, chlorinated paraffin, zinc borate and antimony oxide as a flame retardant system; a carbon layer is generated during combustion so as to adsorb molten and ignited polymers, liquid drops can be prevented from transferring fire disaster, the defect that the conventional NR+SBR+BR rubber compound is extremely easily combusted is overcome, the flame retardant level can reach the UL94V-0 level, and the self-extinguishing requirement is met in a vertical combustion test; and the product has characteristics of simple preparation method, low cost and good use effect, and can completely meet the use requirements of forest firefighters.

Description

technical field [0001] The invention relates to a rubber and a preparation method thereof, in particular to a wear-resistant flame-retardant sole rubber for forest fire-fighting shoes and a preparation method thereof. Background technique [0002] The use environment of forest firefighting shoes is the general situation and abnormal situations such as fire fighting and fire fighting caused by forest fires. In the scene of forest fire fighting, usually the shoes and clothing worn by forest firefighting personnel will contact flames or burning objects for a short time, especially Forest firefighting shoes have more opportunities to touch the burning body, which requires the rubber soles of forest firefighting shoes to have suitable flame retardancy. Reduced performance. Due to the particularity of the environment in which forest firefighting shoes are used, the sole rubber must have sufficient wear resistance in order to exert its comprehensive performance. [0003] Generall...
