Formula and production process for high-temperature-resistant conveyor belt

Abstract

The invention provides a formula and a production process for a high-temperature-resistant conveyor belt. The conveyor belt is prepared by adding the following material components into surface rubber: 100% of EPDM rubber, 2 to 5% of a vulcanizing agent, 0.2 to 0.7% of a promoter, 5 to 9% of an active agent, 1 to 5% of an antiaging agent, 4 to 55% of a reinforcing agent, 10 to 20% of a softening agent, 20 to 50% of aluminum silicate, 4 to 5% of polyamide and about 3% of other material components. According to the invention, due to the selection of the heat-resistant material EPDM rubber and the addition of aluminum silicate and polyamide in the surface rubber of the high-temperature-resistant conveyor belt, heat resistance of the rubber is improved; heat-insulating effect is exerted to the surface rubber and cloth; the temperature of the cloth can be protected from improving, so foaming between the cloth and the rubber is prevented from occurrence, and the conveyor belt can be still used; heat insulation is improved; service life is prolonged; and work efficiency is increased.

Description

technical field [0001] The invention relates to a formula of a conveyor belt, in particular to a formula and a production process of a high-temperature-resistant conveyor belt. Background technique [0002] Since the reform and opening up, the national economy has grown rapidly, "scientific and technological innovation, independent innovation" has become the mainstream of domestic industrial development, and my country's industry is gradually developing in the direction of intensive, energy-saving, emission-reducing, and low-carbon. Conveyor belt, also called conveyor belt, is a rubber, fiber, metal composite product, or plastic and fabric composite product that plays the role of carrying and transporting materials in the conveyor belt. Conveyor belts are mainly used in chemical and building materials industries such as steel mills, coking plants, cement plants, and lime plants. Although the heat-resistant conveyor belts used in the original steel mills, coking plants, ceme...

AI Technical Summary

Problems solved by technology

Although the heat-resistant conveyor belts used in the original steel mills, coking plants, cement plants, lime plants, etc. use heat-resistant raw rubber, heat-conducting materials such as zinc oxide are added to the formula. The heat is quickly transferred to the cloth layer through the heat-conducting material, and the temperature between the cloth layer and the surface glue is quickly raised to 140-150°C; this set of temperatures will cause bubbles between the glue and the cloth, and the tape cannot be used anymore and is scrapped. Production must be replaced with new belts to continue production, which will inevitably increase the cost of the product and cause a lot of waste

The production of high-temperature-resistant conveyor belt surface rubber in traditional technology is usually based on butyl propylene rubber and neoprene, and then heat-resistant surface rubber prepared by other auxiliary materials. The production theory meets the high-temperature-resistant conveyor belt of GB1-T20020-2005 standard. However, due to the poor heat resistance of butadiene-propylene rubber, the high price of neoprene, and the difficulty of the operation process, the high-temperature-resistant conveyor belt produced by it has high cost and low production efficiency. In order to solve the above problems, the scientific research personnel and technical personnel of our unit Continuous research and exploration, development of new conveyor belt formulations and processes, although some progress has been made in technology, but there are still technical problems that have not been overcome in practical application
