Problems solved by technology

However, inorganic materials such as antimony trioxide and aluminum hydroxide are used as flame retardants. Due to their flame retardant ability, they need to be used in large quantities in the formula, which leads to a significant decline in rubber adhesion and other properties, resulting in rubber blooming Abnormal quality problems such as gluing of the apron, the rubber shoes are not durable, have a lot of three wastes, are not environmentally friendly, and have little use value

Abstract

The invention discloses black flame-retardant shoe edge rubber for forest fire-fighting shoes. According to the invention, natural rubber is used as a main material, the filler and the softener are added to ensure the physical properties of the rubber material and ensure the adhesion property of the rubber shoe edge, and the efficient flame retardant decabromodiphenyl ether, chlorinated paraffin and zinc borate are used as a flame retardant system to provide excellent flame retardancy for the product; a carbon layer is generated during combustion so as to adsorb molten and ignited polymers, liquid drops can be prevented from transferring fire, the defect that a conventional NR rubber compound is extremely prone to combustion is overcome, the flame retardant level of the NR rubber compoundcan reach the UL94 V-0 level, and the self-extinguishing requirement is met in a vertical combustion test. The method is simple, low in cost and good in using effect, and can be used by forest firefighters well.

Description

Technical field [0001] The invention relates to a rubber and a preparation method thereof, in particular to a black flame-retardant shoe edge rubber for forest fire fighting shoes and a preparation method thereof. Background technique [0002] The use environment of forest firefighting shoes is general conditions and abnormal situations such as rescue and fire fighting caused by forest fires. In forest fire fighting scenes, shoes and clothing worn by forest firefighters will usually be exposed to flames or burning bodies for a short time, especially in forests. Fire-fighting shoes have more opportunities to touch the burning body, which requires the rubber for forest fire-fighting shoes to have suitable flame retardancy. Therefore, on the premise of sufficient flame retardancy, the continuous burning of the shoe edge rubber can prevent the protective performance from being reduced. [0003] Generally, neoprene rubber is used as the main material of flame-retardant rubber, and its f...
