[0002] Safety shoes are shoes that provide safety protection for the feet. The selection of safety shoes should be based on the nature and degree of hazards in the working environment. Special protection safety shoes should be checked and kept clean after use and stored in a dry and pollution-free place. There are many types of safety shoes, such as toe protection, puncture resistance, insulation, acid and alkali resistance, etc.

[0012] Step 3: After cooling to 55-60°C, add the remaining adhesive, halogen-free flame retardant and surface modifier, and stir until mixed evenly;

[0013] Step 4: Cooling to room temperature to obtain a prepolymer;

[0014] Step 5: Then carry out conventional pouring and demoulding work to obtain the wear-resistant labor protection shoe sole material.
