Problems solved by technology

At present, the main reason for the poor high temperature resistance is that the polyurethane layer formed after the first bath isocyanate self-polymerization reacts with the residual amines of the amine rubber accelerator under the action of high temperature for a long time after the rubber is vulcanized. are decomposed, resulting in failure of the adhesive layer

Abstract

The invention discloses a high temperature-resistant dipping formula, which includes a first bath formula and a second bath formula, and the parts by weight are as follows: wherein, the first bath formula includes the following content: caprolactam blocked isocyanate 40%: 55-60, RF Resin solution: 25‑60, soft water: 878–1200, of which, the formula of RF resin solution is: soft water: 42–52, sodium hydroxide 5%: 10‑12, resorcinol solid: 13–20, formaldehyde 37 %: 25–30. The high-temperature-resistant dipping formula provided by the invention is especially suitable for producing high-temperature-resistant conveyor belts with a conveying material temperature above 200 degrees, and has the characteristics of good high-temperature aging performance of the dipped layer and long service life of the conveyor belt.

Description

technical field [0001] The invention relates to the technical field of industrial fabrics, in particular to a high temperature resistant dipping formula. Background technique [0002] Polyester industrial textiles use polyester industrial yarn as the main raw material. Polyester industrial yarn has become the main raw material of industrial textiles due to its high strength, high modulus, high temperature resistance and other excellent properties. Mechanical rubber products-rubber conveyor belts, transmission belts 1. The skeleton material necessary for rubber hoses has been basically polyesterized at present. The melting point of polyester material is 264°C, and it has good heat resistance. Therefore, polyester dipped canvas has generally replaced the earlier cotton canvas, and it has shown its strong advantages in the application fields of various high-temperature resistant conveyor belts. [0003] For the transportation of coal slag in power plants, sintered ore and slag...
