AI Technical Summary

Problems solved by technology

With the rapid development of science and technology, more stringent performance requirements are put forward for the steel cord rubber core adhesive. The existing traditional rubber can no longer meet the requirements of the process.
The commonly used high-temperature-resistant steel cord adhesive glue is realized by adding a large amount of high-temperature-resistant plasticizer and anti-aging agent, which greatly restricts the physical and technological properties of the rubber material, and there are obvious deficiencies in technological performance in actual production.
It is still difficult to produce and process high temperature resistant steel wire rope core rubber core adhesive glue

Abstract

The invention relates to a rubber formula, in particular to high-temperature-resistant steel wire rope rubber core adhesive and a preparing method thereof. According to the technical scheme for solving problems existing in the prior art, the high-temperature-resistant steel wire rope rubber core adhesive is prepared from, by weight, 100 parts of ethylene-propylene-diene monomer (EPDM) rubber, 0.8 part of an accelerating agent NOBS, 1.5-4.5 parts of a vulcanizing agent DCP, 0-2.4 parts of sulfur S, 8 parts of an active agent ZNO, 1.4 parts of stearic acid (SA), 3 parts of MGO(magnesium oxide), 2 parts of an anti-ageing agent, 55 parts of high-abrasion-resistant carbon black ISAF-HM, 0-15 parts of plasticizer paraffin oil, 10-40 parts of polyisobutene, 10 parts of white carbon black SIO2, 0-4 parts of adhesion promoter PM-18 and 1.8-2.0 parts of cobalt boroacylate RC-23. The prepared adhesive is free of cracking or delamination when continuously used at 180 DEG C; the used materials are general and easy to obtain, and the adhesive is not limited by imported raw materials, is low in cost and meets the requirement for continuous use under the high-temperature condition.

Description

technical field [0001] The invention relates to a rubber formula, in particular to a high-temperature-resistant steel cord rubber core adhesive glue and a preparation method thereof. Background technique [0002] At present, the rubber hose industry is developing at a high speed. With the continuous improvement of the industry's automation, the market's requirements for products are getting higher and higher. From the original non-fixed-length coreless production to the current large-length cored production, the hard cored production in the cored production takes up a lot of space, is labor-intensive, and has low efficiency, so effective large-length production cannot be realized. The production of soft cores takes up little space and is highly efficient, but continuous high-temperature use of soft cores at 150-180 degrees each time is very easy to cause premature aging of soft cores. The main manifestations are cracking, delamination, fracture, candied haws shape, and deta...
