Abstract

The invention discloses a super-cutting-resistant rubber material for a screen plate of a vibrating screen and a preparation method of the super-cutting-resistant rubber material. The super-cutting-resistant rubber material comprises the following components in parts by weight: 100 parts of oil-unloaded butadiene styrene rubber, 25-65 parts of reinforcing filler, 0.5-3 parts of sulfur, 0.8-5 parts of a vulcanization accelerator, 3-12 parts of a vulcanization activator, 2-12 parts of a silane coupling agent Si-69, 1-5 parts of cobalt boroacylate, 4-20 parts of a plasticizer and 1-8 parts of an anti-aging agent, wherein the oil-unloaded butadiene styrene rubber contains 22.5-24.5% of styrene. The preparation method comprises the steps of mixing at the first stage; cooling at the first stage; mixing at the second stage; and cooling at the second stage. By using the super-cutting-resistant rubber material, the cutting resistance is greatly improved, and the service life of the screen plate of the vibrating screen is greatly prolonged.

Description

technical field [0001] The invention discloses a super-cut-resistant rubber compound used for the vibrating screen plate, and also discloses a preparation method of the super-cut-resistant rubber compound used for the vibrating screen plate. Background technique [0002] Vibrating sieve plates are widely used in the production process of mining, coal preparation, building materials, metallurgy and other industries. The purpose is to sort the mixture of materials into required sizes. In recent years, with the rapid development of China's economy, the scale of the above-mentioned industries has been continuously expanded, and the efficiency has been continuously improved, thus putting forward higher requirements for the screening and transportation parts in the production process - vibrating screen sieve plates. [0003] Due to the different shapes and sizes of the materials transported in mining, coal preparation, building materials, metallurgy, etc., when they fall from a ce...
