Embodiment Construction

[0008] This embodiment adopts the following technical solutions: its formula consists of: 3# smoked sheet 10-15 kg, butadiene rubber 10-15kg, styrene-butadiene rubber 5-10kg, carbon black 18-20kg, white carbon black 6-8kg , silane coupling agent 1-1.5kg, reclaimed rubber short fiber 4-8kg, sulfur 0.5-0.8kg, anti-aging agent 0.5-0.8kg, active agent 1.5-2.0kg, accelerator 0.5-1.0kg, softener 5-7 kg.

[0009] The carbon black is high wear-resistant N330, the white carbon black is superfine precipitated white carbon black, the silane coupling agent is SI69, and the short fibers of reclaimed rubber are the short fibers of a certain amount of rubber attached to the surface that are stripped out during the production of reclaimed rubber. For fiber, the anti-aging agent is anti-aging agent 4010NA and RD combined, the active agent is zinc oxide, the accelerator adopts the after-effect accelerator CZ and DM combined system, and the softener adopts softening oil and coumarone.

Abstract

The invention discloses a high-strength rubber lining formula, and relates to the manufacturing field of lining rubber of steel rubber composite pipelines. The formula is composed of the following components by weight: 10 to 15 kilograms of No.3 smoked sheet, 10 to 15 kilograms of cis-polybutadiene, 5 to 10 kilograms of butadiene-styrene rubber, 18 to 20 kilograms of carbon black, 6 to 8 kilograms of white carbon black, 1 to 1.5 kilograms of silane coupling, 4 to 8 kilograms of reclaimed rubber short fiber, 0.5 to 0.8 kilogram of sulfur, 0.5 to 0.8 kilogram of anti-aging agent, 1.5 to 2.0 kilograms of activator, 0.5 to 1.0 kilogram of promoter, and 5 to 7 kilograms of softener. The formula greatly improves the stretching strength, tearing strength, wear resistance, and particle impact resistance of the rubber lining, prolongs the product service life, and satisfies the mineral production requirements.

Description

[0001] Technical field: [0002] The invention relates to the field of production of steel-rubber composite pipeline lining rubber, in particular to a high-strength rubber lining formula. Background technique: [0003] At present, the rapid development of my country's national economy requires that the mining and development of metal mine resources be accelerated, and higher requirements are put forward for the rubber lining of mining equipment and the lining rubber of mine slurry transmission pipelines in terms of wear resistance, tear resistance, and impact resistance. The traditional rubber lining formula is made of ordinary rubber and carbon black for reinforcement, which has low performance in terms of tear resistance, impact resistance and wear resistance, and the product life is still not well enough to meet the needs of mine production. Invention content: [0004] The purpose of the present invention is to provide a high-strength rubber lining formula, which gr...
