Abstract

The invention relates to a preparation method of an antiskid abrasion-resistant rubber sole material, belonging to the technical field of rubber materials. The preparation method comprises the following steps: by using desulfurized gypsum as a raw material, carrying out screening, grinding, acid treatment, floatation and ball milling treatment, and preparing gypsum whiskers under the action of a mixed nucleation agent; taking a hard alloy, carrying out surface roughing treatment, and coating a polyisohydrogen acid ether adhesive to obtain pretreated hard alloy particles; sequentially adding rubber, the gypsum whiskers, sulfur and the like into a Banbury mixer and a calender to perform compounding and calendering, thereby obtaining a sizing material; and putting the sizing material into a sole mold, spreading the pretreated hard alloy particles on the upper surface, carrying out press mold vulcanization forming in a vulcanizer, and demolding to obtain the antiskid abrasion-resistant rubber sole material. Under the action of stress, the rubber can skid on the alloy particle surface, so that the stress in the material is redistributed, thereby avoiding the stress concentration, enhancing the outside friction resistance of the rubber, and further enhancing the abrasion resistance of the rubber.

Description

technical field [0001] The invention relates to a preparation method of an anti-slip and wear-resistant rubber sole material, which belongs to the technical field of rubber materials. Background technique [0002] People often slip or even fall during walking due to road conditions, shoes they wear, etc. Once a fall occurs, it may cause harm to the human body, especially for the elderly. Damage to muscles and bones, and even death. Therefore, the anti-slip and wear-resistant properties of the soles are particularly important. Shoes will inevitably have friction and wear with the ground during the wearing process, and the anti-slip and wear-resistant performance has become an important indicator to measure the function of the sole. [0003] The new anti-wear and anti-skid material has developed from a single material to a composite material. Calcium sulfate whiskers have the advantages of high strength, good toughness, high temperature resistance, and chemical corrosion res...
