Abrasion-resistant antistatic odorless shoe sole rubber and its preparation method and application

Abstract

The invention discloses a wear-resistant and anti-static flavorless sole rubber as well as a preparation method and an application thereof. The wear-resistant and anti-static flavorless sole rubber comprises the following components by weight: 65 to 75 parts of standard rubber, 25 to 35 parts of butadiene rubber, 1.8 to 2.2 parts of brimstone, 2.2 to 2.6 parts of vulcanization accelerator, 2.5 to 3.5 parts of stearic acid, 4.5 to 5.5 parts of nano zinc oxide, 25 to 32 parts of bobbin oil, 50 to 60 parts of N220 carbon black, 2.0 to 3.0 parts of antiager and 7 to 9 parts of conductive carbon black. According to the invention, improvement on the size formula and the preparation method of the sole rubber is carried out, products obtained through the invention are enabled to be flavorless and favorable in wear resisting performance and anti-static performance, and the purposes of enabling the Akron abrasion volume of the vulcanized sole rubber to be smaller than 0.4 cm<3> / 1.61 km, and enabling the resistance value to be 0.1 to 50 M omega can be achieved. The method provided by the invention is simple and feasible, the material sources are wide, the cost is low, and the using effect of product is excellent.

Description

technical field [0001] The invention relates to the field of rubber processing, in particular to a wear-resistant, antistatic and odorless sole rubber, a preparation method and application thereof. Background technique [0002] In shoemaking, especially in the manufacture of anti-static rubber shoes, in order to realize the anti-static function of rubber, it is necessary to use a large amount of acetylene carbon black in the formula, and the use of acetylene carbon black causes the rubber to fail to meet the wear resistance of the sole, The unity of high tensile performance and antistatic performance. On the one hand, in order to achieve the wear resistance of rubber, it is necessary to reduce the amount of acetylene carbon black, which will lead to a decrease in antistatic performance, and in order to improve the antistatic performance, it is necessary to add liquid antistatic Electrostatic agents can cause quality problems such as rubber spit cream and severe odor. On th...

[0002] In shoemaking, especially in the manufacture of anti-static rubber shoes, in order to realize the anti-static function of rubber, it is necessary to use a large amount of acetylene carbon black in the formula, and the use of acetylene carbon black causes the rubber to fail to meet the wear resistance of the sole, The unity of high tensile performance and antistatic performance

On the one hand, in order to achieve the wear resistance of rubber, it is necessary to reduce the amount of acetylene carbon black, which will lead to a decrease in antistatic performance, and in order to improve the antistatic performance, it is necessary to add liquid antistatic Static agent will cause rubber spit cream, serious odor and other quality problems

On the other hand, in order to achieve good anti-static performance and ensure the anti-spitting properties of the product, it must be at the expense of the wear resistance and tensile properties of the rubber shoes. In this way, the use of acetylene carbon black in large doses will increase the service life of the rubber shoes. The range is reduced, which cannot meet the needs of users. At the same time, it is very difficult to make rubber with acetylene carbon black, and the manufacturing cost of the product is very high. The antistatic performance of rubber is unstable due to the serious flying loss of acetylene carbon black.
