Abstract

The invention discloses a flame-retardant shoe sole material which is characterized by comprising the following components: 90-110 parts of chloroprene rubber, 40-60 parts of carbon black, 15-25 parts of dibutyl ester, 4-8 parts of antimony trioxide, 10-20 parts of chlorinated paraffin, 3-7 parts of zinc white, 1-2 parts of stearic acid, 0.5-1.5 parts of accelerator M, 1-2 parts of accelerator DM, 0.5-1.5 parts of anti-aging agent 4010, 0.5-1.5 parts of anti-aging agent RD, 0.5-1.5 parts of sulfur, 1-5 parts of magnesia and 0.6-1 part of accelerator NA-22. The preparation method comprises the following steps: plastifying, banburying, open milling, cooling, vulcanizing and the like. Various additives are added into the chloroprene rubber and treated, so that the shoe sole material can effectively retard flame when contacting an ignition source and prevent the danger due to combustion of the shoe sole.

Description

technical field [0001] The invention relates to the field of sole materials, in particular to the field of flame-retardant sole materials. Background technique [0002] Neoprene is a synthetic rubber compound that is produced in large quantities. Neoprene has a wide range of applications, mainly used in home and public facilities decoration, wood industry, shoe industry and other industries. Neoprene has many characteristics such as high bonding strength, strong flexibility, good medium resistance, and good elasticity. [0003] However, the heat resistance of neoprene is very poor, and it will burn in case of fire and produce a lot of smoke. For many special types of work, such as firefighters, due to the need for long-term exposure to fire sources, using neoprene soles can be very dangerous. Contents of the invention [0004] Purpose of the invention: The purpose of the present invention is to address the deficiencies of the prior art and provide a flame-retardant shoe...
