Environmentally-friendly double-component high temperature-resistant conveyer belt bonding agent and preparation method thereof

Abstract

The invention discloses an environmentally-friendly double-component high temperature-resistant conveyer belt bonding agent and a preparation method thereof. The environmentally-friendly double-component high temperature-resistant conveyer belt bonding agent comprises a component A and a component B. The component A comprises: by weight, 50 to 100 parts of chloroprene rubber, 10 to 20 parts of methacrylic acid, 0.1 to 0.3 parts of benzoyl peroxide, 0.1 to 0.2 parts of hydroquinone, 30 to 70 parts of alkyl benzoic acid resin, 2 to 10 parts of active magnesium oxide, 5 to 10 parts of zinc oxide, 10 to 20 parts of aluminum hydroxide, 200 to 300 parts of acetic ester, 200 to 300 parts of butanone, 100 to 300 parts of dimethyl carbonate, 0.3 to 0.7 parts of triethanolamine and 0.5 to 1.0 part of pigment. The component B comprises 10 to 40 parts of polyisocyanate, 1 to 5 parts of thiocyanuric acid, 50 to 150 parts of acetic ester and 0.1 to 0.3 parts of a polymerization inhibitor.

Description

technical field [0001] The invention relates to a two-component high temperature resistant conveyor belt adhesive, in particular to an environmentally friendly [0002] A two-component high temperature resistant conveyor belt adhesive and a preparation method thereof. Background technique [0003] In thermal power plants, coking plants, steel plants, cement plants and other national economic lifeline enterprises, high-temperature materials account for a considerable proportion of the entire material transportation, and high-temperature material transportation occupies a pivotal position in the entire production process. So far, the bonding of high-temperature material conveyor belts mainly adopts thermal vulcanization, mechanical bonding and normal temperature bonding: [0004] Hot-vulcanized rubber bonding is to use various rubbers together with filler vulcanizing agents and accelerators, and vulcanize and bond under high temperature and high pressure. [0005] The mechan...

AI Technical Summary

Problems solved by technology

[0004] Hot vulcanization glue bonding is to use various rubber with filler vulcanizing agent and accelerator, vulcanization bonding under high temperature and high pressure, not only time-consuming and laborious, low labor efficiency, but also short life of the joint, shortening the service life of the belt

[0005] The mechanical connection method is to use belt buckle connection, metal sheet riveting and suture connection, simple operation, fast speed, detachable, but low strength, poor flexibility at the joint, easy to damage the drum and other components, vibration, noise, leakage, etc.

[0006] Normal temperature conveyor belt adhesive bonding generally relies on the crystallization of neoprene rubber itself to produce adhesive force. The cohesive strength of the adhesive is low. After the temperature exceeds 80°C, the strength drops very low, which cannot meet the needs of enterprise production.
