Abstract

The invention provides a dipping solution for high-temperature-resistant industrial canvas and a preparation method of the dipping solution. The dipping solution is prepared from the following raw materials in parts by weight: 50-70 parts of soft water, 0.1-0.2 part of solid-state sodium hydroxide, 110-130 parts of nitrile latex, 70-80 parts of butadiene-vinylpyridine latex, 12-14 parts of ammonia water, 178-181.4 parts of an RF solution and 11-14 parts of isocyanate, wherein the RF solution is prepared from the following raw materials in parts by weight: 139-170 parts of soft water, 0.17-0.21 part of solid-state sodium hydroxide, 9-11 parts of resorcinol and 7.3-16.2 parts of formaldehyde. Compared with the prior art, the dipping solution adopts the nitrile latex and the butadiene-vinylpyridine latex as main bodies, enhances the adhesion property of a framework layer and a rubber layer, enhances the adhesion property among high-temperature layers of a conveying belt, and prolongs the service life of the conveying belt.

Description

technical field [0001] The invention relates to the field of canvas treatment, in particular to a dipping solution for high-temperature-resistant industrial canvas and a preparation method thereof. Background technique [0002] The skeleton material of the conveyor belt is polyester dipped canvas. The melting point of polyester material is 264°C and has good heat resistance. Therefore, polyester dipped canvas has generally replaced the earlier cotton canvas. It is used in various high temperature resistant conveyor belts. Its powerful advantages are shown in the application field. [0003] Polyester dipped canvas is an important part of the conveyor belt, which bears almost all the loads of the conveyor belt during operation. At present, the two-bath method is relatively mature in the production of polyester canvas dipping. The first bath uses water-based latex, and the second bath is the traditional resorcinol-formaldehyde-latex dipping solution. This traditional dipping s...
