High-wear-resistant, anti-color-permeation and high-strength inner surround strip formula and preparation method thereof

Abstract

The invention discloses a high-wear-resistant, anti-color-permeation and high-strength inner surround strip formula. The inner surround strip is composed of, by weight, 70-90 parts of secondary M-added plasticated rubber, 10-30 parts of polyisoprene IR80, 0.5-1.5 parts of carbon fiber, 10-30 parts of active carbon black rubber master batch, 3-5 parts of zinc oxide, 0.5-1.3 parts of stearic acid, 1.5-2 parts of sulfur, 0.3-0.6 parts of an accelerant P-84, 0.5-1.8 parts of an accelerant M, 0.4-1 part of an accelerant NS, 1-2 parts of an accelerant DM, 0.5-1.1 parts of an anti-aging agent SP-C, 1.5-2 parts of PEG-4000, 20-35 parts of white carbon black 185C, 3-5 parts of naphthenic oil and 95-110 parts of light calcium carbonate. The inner surround strip is improved in tensile strength, can prevent color migration and is reduced in abrasion. Shoes made from the inner surround strip have better appearance and are prolonged in service life.

Description

technical field [0001] The invention relates to the field of rubber rubber shoes, in particular to a main material formula of rubber rubber shoes and a preparation method thereof. Background technique [0002] Rubber shoes are mainly composed of upper material and rubber parts, and the rubber parts include soles and aprons. The connection between the upper and the sole is realized through the apron, one is to cover the gap at the joint, so the apron with various patterns can improve the variety and aesthetics of the rubber shoes, and the other is that when the apron is cured in the vulcanization tank Will shrink to prevent the outsole from bouncing off. [0003] As the main part of vulcanized rubber shoes, the perimeter strip is composed of the outer perimeter strip and the inner perimeter strip. The inner perimeter strip is what we call the main material. The main function of the main material is to stick to the connection between the outsole and the upper together with th...

Problems solved by technology

Since the peripheral strip is only attached to the main material in a thin layer, the main material, like the outsole, has a part that is in direct contact with the ground and will be subjected to frequent bending and wear. If the strength is not high and the wear resistance is not good Well, it will affect the quality and comfort of the shoes

[0004] For the anti-see-through color, because the surrounding strip is in direct contact with the outsole, if the color of the outsole is unstable, it is very easy to migrate to the main material, and finally migrate to the peripheral strip, which will affect the appearance of the shoe
