Abstract

The invention provides a dipping solution used for producing dipped polyester canvas by a single bath method and a preparation method thereof. The dipping solution comprises the following components in parts by mass: 140-170 parts of soft water, 10-12 parts of resorcinol, 13-15 parts of formaldehyde, 15-20 parts of p-chlorophenol, 250-350 parts of styrene-butadiene-vinylpyridine copolymer latex, 10-15 parts of ammonia water, 18-20 parts of an isocyanate solution, and 0.3-1 part of sodium hydroxide. The phenolic resin containing a p-chlorophenol solution is used to form tight chemical bond between the resin and the fabric produced by the fiber by dipping the polyester fiber fabric and drying at a high temperature, the chemical bonding strength of a polyester fiber-based skeleton material isenhanced, the strength of the polyester fiber is improved, and the preparation method is provided, the preparation efficiency of the dipping solution is increased, and the quality of the dipping solution is improved.

Description

technical field [0001] The invention relates to the field of industrial cloth manufacturing, in particular to a dipping solution for producing dipped polyester canvas by a single-bath method and a preparation method thereof. Background technique [0002] At present, in the manufacture of polyester fibers, ordinary polyester fibers lack active groups due to their own molecular structure. When treated by impregnation, when they react with phenolic resins, the chemical bonds produced are weak, resulting in fiber and resin base, fiber and The peel strength between rubber-like elastomers is low, which will easily lead to a decrease in the quality and service life of the rubber composite that uses polyester fibers as reinforcement and reinforcement skeleton. Therefore, it is particularly important to solve the problem of low peel strength of ordinary polyester fibers. Contents of the invention [0003] For the problems existing in the above-mentioned prior art, the purpose of t...
