High-stiffness lustered yellowing-resistance bleached shoe side rubber and preparation method thereof

Abstract

The invention discloses high-stiffness lustered yellowing-resistance bleached shoe side rubber, which comprises 80 to 90 weight parts of No.1 standard rubber, 10 to 20 weight parts of solution polymerized butadiene styrene rubber 2003, 18 to 25 weight parts of high styrene, 1 to 3 weight parts of sulfur, 2.4 to 2.8 weight parts of microcrystalline wax, 2.2 to 2.6 weight parts of promoter, 5 to 6 weight parts of stearic acid, 2.5 to 3.4 weight parts of nano zinc oxide, 4 to 5 parts of polyethylene glycol 4000, 1 to 2 weight parts of antiaging agent, 1.7 to 2.1 weight parts of ultramarine, 53 to 60 weight parts of titanium white, 50 to 60 weigh parts of white carbon black, 30 to 40 weight parts of nano calcium carbonate, 0.1 to 0.15 weight part of 4-percent pigment permanent violet and 7 to 9 weight parts of white engine oil. In the invention, the formula and preparation method of the product are improved, and shoe side rubber, which has high rubber stiffness and luster and is yellowing-resistance and as white as snow, can be obtained by screening.

Description

technical field [0001] The invention relates to a rubber and a preparation method thereof, in particular to a shoe edge rubber and a preparation method thereof. Background technique [0002] According to the needs of the application, there are many different proportioning schemes for the shoe edge rubber. The most commonly used one is to use diethylene glycol or triethanolamine to activate the rubber. However, the vulcanized rubber obtained in this way has a low snow whiteness, low gloss, and is matte. 1. The stiffness of the semi-finished rubber material is unstable, the shape retention of the pattern is poor, the traces of the sole are exposed, it is easy to cause compression deformation, and the appearance of the product is not clear; and the yellowing resistance under the sun lamp B method reaches 3 to 5 grades, while Those below grade 3 must use high-priced materials such as anti-yellowing accelerators and ultraviolet light absorbers; the size of the shoe film is unstab...

Problems solved by technology

[0002] According to the needs of the application, there are many different proportioning schemes for the shoe edge rubber. The most commonly used one is to use diethylene glycol or triethanolamine to activate the rubber. However, the vulcanized rubber obtained in this way has a low snow whiteness, low gloss, and is matte. 1. The stiffness of the semi-finished rubber material is unstable, the shape retention of the pattern is poor, the traces of the sole are exposed, it is easy to cause compression deformation, and the appearance of the product is not clear; and the yellowing resistance under the sun lamp B method reaches 3 to 5 grades, while Those below grade 3 must use high-priced materials such as anti-yellowing accelerators and ultraviolet light absorbers; the size of the shoe film is unstable, it is difficult to ensure the stability of the appearance, and the product grade is low; the physical properties of this vulcanized rubber are: tensile strength 7 ~ 9Mpa, elongation at break 300 ~ 400%, after the rubber shoes are bent 5,000 times, cracks begin to appear on the surface of the rubber shoes film, and the bending resistance is poor

The above properties have caused the existing vulcanized rubber to have many deficiencies when used as shoe edge rubber, and it is difficult to meet the needs of use.
