Bending-resistant calendered leaf-yellow rubber edge strip rubber for liberation shoes, and preparation method and application thereof

Abstract

The invention discloses a bending-resistant calendered leaf-yellow rubber edge strip rubber for liberation shoes, which comprises the following components in parts by weight: 75-85 parts of standard rubber, 20-25 parts of butadiene styrene rubber, 15-25 parts of silica white, 2.0-2.4 parts of sulfur, 3.6-4.0 parts of vulcanization accelerator, 1.4-1.8 parts of stearic acid, 1.8-2.2 parts of activated zinc oxide, 8-10 parts of pine tar, 60-70 parts of argil, 2.0-2.4 parts of anti-aging agent, 4-8 parts of compound resin DS-B, 8-10 parts of calcium grease, 26-34 parts of light calcium carbonate and 7-9 parts of leaf-yellow master batch. Every 108.7 parts of leaf-yellow master batch is composed of 50 parts of rosin butadiene styrene rubber, 4 parts of paraffin, 0.8 part of N330 carbon black, 0.9 part of phthalocyanine green G and 53 parts of medium chrome yellow.

Description

technical field [0001] The invention relates to the field of rubber material preparation, in particular to a calendered leaf-yellow rubber wrapping glue for tortuous-resistant liberation shoes, a preparation method and application thereof. Background technique [0002] Calendered leaf-yellow rubber enclosures for Jiefang shoes usually use natural rubber as the skeleton material, thiuram and thiazole accelerators to form an AA-type accelerator system, and the filling system uses calcium carbonate, quartz powder, etc. as the main materials. The preparation method adopts a one-time feeding method, and various materials are directly batched. This kind of system usually has the following problems: (1) The reinforcement of the rubber is poor, (2) The vulcanization accelerator system has after-effect and super-speed vulcanization. Since the vulcanization of the rubber is generally slow at the beginning, the vulcanization speed of the rubber is affected during the use of the rubber....

AI Technical Summary

Problems solved by technology

This kind of system usually has the following problems: (1) The reinforcement of the rubber is poor, (2) The vulcanization accelerator system has after-effect and super-speed vulcanization. Since the vulcanization of the rubber is generally slow at the beginning, the vulcanization speed of the rubber is affected during the use of the rubber. It is difficult to control, which leads to quality defects such as low scorch resistance of rubber materials, high brittleness of vulcanized rubber, and poor bending resistance of products

(3) Due to the unreasonable reinforcement system, the color of the rubber material is not correct, and the appearance is not good

(4) All natural rubber is used, and the performance of the rubber material is unstable due to large fluctuations in temperature.

Therefore, the production efficiency of the product is not high, and the hue and service life of the rubber material cannot meet the needs of consumers
