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 textile glue formula, which comprises a first bath formula and a second bath formula. The first bath formula comprises following components in parts by weight: 55 to 60 partsof caprolactam enclosed isocyanate, 35 to 60 parts of RF resin liquid, and 800 to 1000 parts of soft water, wherein the RF resin liquid comprises 42 to 52 parts of soft water, 1.0 to 1.2 parts of sodium hydroxide (5%), 1.3 to 2.0 parts of resorcinol solid, and 2.5 to 3.0 parts of formaldehyde (37%). The provided textile glue formula is especially suitable for the production of a high temperatureresistant conveyer belt that can deliver materials with a temperature higher than 200 DEG C. The high temperature aging resistant performance of a textile glue layer is good. The service life of the conveyer belt is long.

Description

technical field [0001] The invention relates to the technical field of industrial fabrics, in particular to a textile glue 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 textile glue 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. For the transportation of coal slag in power plants, sintered ore and slag in iron and steel plants...
