Calendered black rubber apron for Jiefang shoes and its preparation method and application

Abstract

The invention discloses calendering type black rubber edge strip gum, comprising the following components in parts by weight: 75-80 parts of standard rubber, 20 to 25 parts of styrene-butadiene rubber, 2.0 to 2.4 parts of sulfur, 3.6 to 4.0 parts of a vulcanization accelerator, 1.4 to 1.8 parts of stearic acid, 1.8 to 2.2 parts of activated zinc oxide, 8 to 10 parts of pine tar, 80 to 90 parts of clay, 2.0 to 2.4 parts of an antioxidant, 4 to 8 parts of a composite resin DS-B, 8 to 10 parts of calcium base grease, 28 to 32 parts of light calcium carbonate and 4 to 6 parts of N330 carbon black.

Description

technical field [0001] The invention relates to the field of rubber material preparation, in particular to a calendered black rubber wrapping glue for Jiefang shoes and its preparation method and application. Background technique [0002] The calendered black rubber enclosure glue for Jiefang shoes usually uses 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 method adopts the 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. It is difficult to control, which le...

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 has insufficient blackness, incorrect hue, and poor appearance

(4) A large amount of 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 service life cannot meet the needs of consumers.
