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 the physical properties of the rubber and the formation of abnormal quality problems such as rubber blooming. , the rubber shoes are not durable to wear, there are many three wastes, not environmentally friendly, the use value is small, and the application range is low

Abstract

The invention discloses a black green flame-retardant shoe edge rubber for forest fire protection shoes. According to the invention, natural rubber and chloroprene rubber are used as the main materials, reinforcing filler and a softener are added to guarantee the physical properties of the rubber material, and the service life of a rubber sole is ensured, so that the shoe edge rubber has forest green coordination, and efficient flame retardants decabromodiphenyl oxide, chlorinated paraffin and zinc borate are adopted as a flame retardant system together to provide excellent flame retardance tothe product; the shoe edge rubber can generate a carbon layer during combustion, can achieve rapid flame retarding and no liquid drop transfer of fire, overcomes the defect of great flammability of conventional NR rubber compounds, has flame-retardant level up to the UL94V-0 level, and meets the self-extinguishing requirement in vertical combustion test. The shoe edge rubber provided by the invention has the characteristics of simple method, low cost and good use effect.

Description

technical field [0001] The invention relates to a rubber and a preparation method thereof, in particular to a dark green flame-retardant edge rubber for forestry 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 There are more chances of forest fire shoe corners and burning objects, which requires the rubber soles of forest fire shoes to have suitable flame retardancy. Therefore, under the premise of sufficient flame retardancy, the continuous combustion of sole rubber can prevent The protective performance is reduced. Due to the particularity of the environment in which forest firefighting shoes are used, the...
