Abstract

The invention aims to provide a dipping solution formula of an industrial canvas and a preparation process thereof. The dipping solution formula comprises a first bath formula and a second bath formula. The dipping solution formula and the preparation process have the beneficial effects that 2-chloromethylthiobenzothiazole is added to a two-bath dipping solution, so that unreacted resorcinol is etherified through etherification reaction, thus the content of free resorcinol is less than 1% and the harms to workshop workers and the environment are reduced; during dipping solution preparation, an organic solvent serves as a carrier to form a solvent type dipping system, so that high tenacity of the canvas can be ensured while endowing the canvas with high degree of adhesion, thus forming a product with high added values; release of toxic substances in the dipping process is reduced and the environment is protected by adopting the environment-friendly dipping system.

Description

technical field [0001] The invention relates to the technical field of sizing material for impregnating chemical fiber and synthetic fiber fabrics, in particular to a formula of dipping liquid for industrial canvas and a preparation process thereof. Background technique [0002] In recent years, the emergence of new high-performance synthetic fiber materials has accelerated the development of industrial canvas materials, but how to further improve the bonding performance between fiber skeleton materials and rubber has always been a difficult issue. In the traditional dipping system, RFL dipping solution is used, that is, resorcinol-formaldehyde-latex dipping system, and isocyanate is added as a crosslinking agent. Since the cohesive energy density of polyester is not like that of RF resin, the molecular contact between RFL dipping solution and polyester phase is poor. Moreover, resorcinol is easy to volatilize in a high temperature environment, which not only reduces the co...
