Abstract

The invention discloses an environment-friendly high-temperature-resistant conveyor belt binder and a preparation method thereof. The binder is prepared from the following components in parts by weight, 450-550 parts of chloroprene rubber, 300-400 parts of methyl methacrylate, 10-18 parts of BPO, 3500-4500 parts of trichloroethylene, 200-400 parts of alkyl phenolic resin, 4-9 parts of active magnesium oxide, 40-50 parts of tetraisocyanate, 3000-4000 parts of ethyl acetate, 4-6 parts of an anti-aging agent D50, 6-8 parts of 2, 4, 6-tetramethyl-1, 3-pentanediol monoisobutyrate. Wherein the component A is prepared from the following components in parts by weight: 10-30 parts of 2, 4, 6-trinitrophenol and 300-500 parts of water; the invention provides an environment-friendly high-temperature-resistant conveying belt binder and a preparation method thereof. The chloroprene rubber is grafted with methyl methacrylate, so that the chloroprene rubber is changed from linear macromolecules into body-shaped macromolecules, the viscosity of the adhesive is improved, and the adhesive still has excellent viscosity at high temperature due to the specific structural advantages of the body-shaped macromolecules and the combined action of the anti-aging agent.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environment-friendly high-temperature-resistant conveyor belt adhesive and a preparation method thereof. Background technique [0002] The heat-resistant conveyor belt mainly transports coke, slag, cement and other objects with a temperature greater than or equal to 170°C, which are commonly used objects in the construction and smelting industries. The heat-resistant conveyor belt consists of a metal skeleton and a fabric layer covering the surface of the metal skeleton that is in direct contact with the hot object. The fabric layer is usually polyester canvas or rubber polyester cotton cloth. The polyester canvas or rubber polyester cotton cloth is bonded to the metal frame by adhesive. Most of the existing adhesives are linear polymer mixtures. The molecular chains of the linear polymers are only linked by van der Waals force. The viscous force performs well at low temper...
