Flexible energy-saving super-wear resistant covering glue for steel wire rope core conveyor belt and preparation method thereof

Abstract

The invention discloses flexible energy-saving super-wear resistant cover rubber for a steel wire rope core conveyor belt and a preparation method thereof, and relates to the field of rubber conveyorbelts. The product comprises the following components in parts by weight: 60-80 parts of natural rubber, 20-40 parts of butadiene rubber, 0.2-0.3 parts of a peptizer, 2-5 parts of an anti-aging agent,0.5-1.5 parts of an antioxidant, 4-7 parts of nano zinc oxide, 1.5-2 parts of stearic acid, 1-1.5 parts of microcrystalline wax, 2-5 parts of a high performance rubber dispersant, 3-5 parts of an anti-wear agent, 5-10 parts of a phenolic reinforcing resin, 1-1.5 parts of an accelerator, 3-5 parts of aromatic oil, 40-70 parts of carbon black, 0.5-1.5 parts of hexamethylenetetramine, and 1.5-2.5 parts of sulfur. The product has the characteristics of wear resistance, tear resistance, high adhesion with core rubber adhesive layers, long service life, and the like.

Description

technical field [0001] The invention relates to the technical field of rubber conveyor belts, in particular to a flexible energy-saving super wear-resistant steel cord conveyor belt covering glue and a preparation method thereof. Background technique [0002] In China, it is customary to call the tunnel boring machine suitable for soft ground as shield machine, and the tunnel boring machine for hard rock ground as TBM, while in Europe, shield machine and TBM are collectively called tunnel boring machine. The shield machine has the advantages of fast excavation, high quality, safety, economy and environmental protection, making it possible for projects that could not be constructed or even unimagined in the past. [0003] Today, as China pays more and more attention to the development and utilization of underground space, with the large-scale construction of infrastructure such as urban transportation and large-scale engineering projects, China has become one of the countries...

AI Technical Summary

Problems solved by technology

[0005] Because the TBM construction technology was invented by a foreign company, when it was introduced in China, it was introduced together with the TBM roadheader and the continuous belt conveyor. Therefore, the continuous belt conveyor has been monopolized by foreign companies. This technology has been monopolized by foreign companies for more than ten years. The import price of the supporting steel cord conveyor belt on the belt conveyor is very expensive

Due to the special requirements of the conveyor belt for the shield machine, the existing domestic steel cord conveyor belt has a thicker overall thickness and a heavier unit weight. It is particularly cumbersome, and it is difficult to achieve ultra-long-distance transportation

Although some domestic enterprises have developed conveyor belts for this special requirement and achieved some results, there is still a gap between their service life and imported products, so it is necessary to conduct further research on this type of conveyor belt
