Abstract

The invention relates to a gum dipping liquid, and in particular relates to a polyester cord thread gum dipping liquid. The gum dipping liquid comprises the following components in parts by weight: 24.8-27.6 parts of phenolic resin mixture, 33.0-34.0 parts of butadiene-vinylpyridine copolymer latex, 15.5-16.5 parts of butadiene latex, 22.1-24.8 parts of water, 0.17-0.20 part of ammonia water, 0.03-0.05 part of peregal and 0.4-0.5 part of modified carbon black, wherein the phenolic resin mixture comprises 5.4-6.1wt% of resorcinol, 4.1-5.14wt% of formaldehyde, 0.1-0.16wt% of sodium hydroxide and the balance of water. According to the gum dipping liquid, the technical problems of complex gum dipping process, week glue line and rubber substrate adhesive force, severe environmental pollution and the like in the prior art can be solved, and a gum dipping liquid formula with a simple gum dipping process and good gum dipping liquid performance is provided.

Description

technical field [0001] The invention relates to a dipping solution, in particular to a polyester cord dipping solution. Background technique [0002] With the improvement of the "radialization" rate of car tires, polyester cords, one of the ideal skeleton materials for radial tires, have developed rapidly. The main characteristics of polyester cord are high modulus and low elongation, so the tire has good dimensional stability and small deformation. These properties are far superior to nylon. After polyester cord is woven into cloth, it must be dipped to have practical value. Due to the low polarity of polyester molecules, high crystallinity, and inactive chemical properties, it has poor adhesion to rubber. Therefore, the adhesion performance of polyester cords to rubber has always been a long-standing key problem. [0003] Due to the low polarity of the chemical structure of the polyester cord, it is not easy to form hydrogen bonds, and the dipping solution with better cr...
