Abstract

The invention discloses an oil-resistant and corrosion-resistant heel logo material and a preparation method thereof, and the oil-resistant and corrosion-resistant heel logo material is prepared by taking butadiene-acrylonitrile rubber, chloroprene rubber and natural rubber as main raw materials and adding substances such as an accelerant, a compatilizer and a reinforcing agent. The accelerant isa mixture of (Z)-3-(2-bromo-3-(trifluoromethyl) styryl)-2, 7-bis (trifluoromethyl) benzofuran, (E)-4-(4-bromo-3-(trifluoromethyl) phenyl)-3-butenenitrile, and ethylene oxide; the reinforcing agent isa mixture of modified graphene, zinc oxide and white carbon black; the modified graphene is prepared by taking graphene oxide and polypropylene resin as raw materials and adding a modifier; wherein the modifier is a mixture of 4, 4 '-bismaleimide diphenylmethane and 2, 2'-diallyl bisphenol A, and the heel logo material finally prepared from the mixture not only has very high tensile strength and very high oil resistance, but also has very high acid and alkali corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an oil-resistant and corrosion-resistant heel standard material and a preparation method thereof. Background technique [0002] The heel label refers to the logo attached to the heel of canvas shoes and other shoes, so as to clearly tell consumers the brand and source of the shoe. At present, most of the heel labels are mostly made of rubber; this is because rubber has good tensile strength and elongation at break, so it is easy to make heel labels of various shapes, further increasing the beauty of shoes, and then increasing the sales of shoes However, the existing heel marking materials have poor oil resistance, and shoes are often exposed to some oily environments, which makes the heel markings swell after the shoes have been used for a period of time, which greatly affects the quality of the shoes. The overall aesthetic feeling also limits the further development o...
