Problems solved by technology

[0002] The two layers of fabric cloth in the fabric core conveyor belt need to be bonded with glue. The glue must have good adhesion performance. At present, this kind of glue in China generally uses the m-formula-white adhesive system. The relative molecular weight of pure resorcinol used in the bonding system is relatively low, and it will sublimate during the processing of rubber materials to produce smoke, which seriously pollutes the environment and endangers the health of employees
[0003] At the same time, a large number of rubber products such as waste tires are treated as waste products in our country every year, which not only pollutes the environment, but also causes waste of resources.

Abstract

The invention relates to an environment-friendly fabric core conveyor belt adhesive tape and a preparation method thereof. The formula comprises the following components in parts by weight: 50-70 parts of natural rubber, 30-50 parts of butadiene styrene rubber, 10-30 parts of environment-friendly reclaimed rubber, 25-75 parts of reinforcing filler, 3-5 parts of zinc oxide, 1-3 parts of stearic acid, 2-5 parts of an anti-aging agent, 1-5 parts of C5 resin, 5-20 parts of environment-friendly aromatic oil, 1-3 parts of modified RS resin, 2-6 parts of a rubber adhesive RA-50, 1.2-2.0 parts of sulfur, 1-1.2 parts of a vulcanization accelerator and 0.1-0.2 part of a scorch retarder CTP. The raw materials are subjected to plastication, first-stage mixing and second-stage mixing to prepare the environment-friendly fabric core conveyor belt adhesive tape. The environment-friendly raw materials are adopted, so that the pollution hidden danger caused to the environment in the production and use processes is greatly reduced, and the safety, the economical efficiency and the adaptability of the product are wider.

Description

technical field [0001] The invention belongs to the technical field of rubber conveyor belts for industrial conveying, in particular to an environment-friendly fabric core conveyor belt glue and a preparation method thereof. Background technique [0002] In the fabric core conveyor belt, the two layers of fabrics need to be bonded with adhesive. The adhesive must have good adhesive properties. At present, this kind of adhesive in China generally uses the inter-A-white adhesive system. The pure resorcinol used in the adhesive system has a low relative molecular weight, which will sublime and generate smog during the processing of the rubber compound, which will seriously pollute the environment and endanger the health of employees. [0003] At the same time, a large number of waste tires and other rubber products are regarded as waste products in my country every year, which not only pollutes the environment, but also causes waste of resources. Many companies recycle and reu...
