Problems solved by technology

Because resorcinol is easy to volatilize in high temperature environment, it not only reduces the concentration of impregnating liquid, but also reduces the adhesion between RFL impregnating liquid and the surface of industrial cloth, and also causes harm to workshop workers.
[0003] Chinese patent application number 201410000732.0 discloses a formula and preparation process of an industrial cloth dipping solution. This invention is applied to industrial cloth dipping, but the formula has many raw materials and the preparation process is complicated
In the processing and production of small-scale enterprises, this method requires long working hours and high labor costs, and is not easy to apply

Embodiment 1

[0019] Prepare 8 kg of natural latex, 12 kg of butylpyridine latex, 12 kg of styrene-butadiene latex, 3 kg of resorcinol, 4 kg of formaldehyde, 1.5 kg of penetrant, 1.5 kg of sodium hydroxide, and 75 kg of purified water.

[0020] First, mix sodium hydroxide and clean water at 60°C in a ratio of 1:4, stir until completely dissolved, cool to room temperature, add natural latex and mix evenly, then add formaldehyde and resorcinol, mix evenly, and make The mixture is ready for use;

[0021] Secondly, dilute the butylpyrrole latex, styrene-butadiene latex, and penetrant with the remaining clean water, stir evenly, and make an emulsion for use;

[0022] Finally, quickly add the emulsion into the mixed solution and stir evenly to make an anti-corrosion dipping solution.

Embodiment 2

[0024] Prepare 9 kg of natural latex, 15 kg of butylpyridine latex, 11 kg of styrene-butadiene latex, 1 kg of resorcinol, 6 kg of formaldehyde, 1 kg of penetrant, 1 kg of sodium hydroxide, and 80 kg of purified water.

[0025] The preparation method is as in Example 1.

Embodiment 3

[0027] Prepare 11 kg of natural latex, 10 kg of butylpyridine latex, 13 kg of styrene-butadiene latex, 5 kg of resorcinol, 2 kg of formaldehyde, 2 kg of penetrant, 2 kg of sodium hydroxide, and 70 kg of purified water.

[0028] The preparation method is as in Example 1.

Abstract

The invention discloses anti-corrosion dipping liquid. The anti-corrosion dipping liquid is composed of, by weight, 9-11 parts of natural emulsion, 10-15 parts of butadiene-vinylpyridine copylymer latex, 11-13 parts of styrene-butadiene latex, 1-5 parts of resorcinol, 2-6 parts of methanal, 1-2 parts of penetrant, 1-2 parts of sodium hydroxide and 70-80 parts of pure water. The natural emulsion is added into the raw materials, so that a film is rapidly formed on the surface of the dipping liquid with which a piece of industrial cloth is dipped, the film can effectively prevent the raw materials from volatilizing, and the bonding performance between the dipping liquid and the surface of the industrial cloth is ensured; meanwhile, through the addition of the penetrant, the anti-corrosion dipping liquid has the advantages of resisting high temperature, acid and alkali and being high in abrasion resistance, and the performance of the dipping liquid is improved; in addition, a preparation method is easy to operate, no long working time is occupied, the labor cost is lowered, and the method is applicable to machining production of small-scale enterprises.

Description

technical field [0001] The invention relates to a dipping solution, in particular to an anti-corrosion dipping solution which is coated on the surface of industrial cloth and has the characteristics of high temperature resistance, acid and alkali resistance and high wear resistance. Background technique [0002] In recent years, the extensive use of industrial fabrics has promoted the improvement of the quality of industrial fabrics. Dipping industrial fabrics is an important part of improving the quality of industrial fabrics. In the traditional dipping system, the RFL dipping solution is used, that is, the resorcinol-formaldehyde-latex dipping system. Because resorcinol is easy to volatilize in high temperature environment, it not only reduces the concentration of impregnation solution, but also reduces the adhesion between RFL impregnation solution and the surface of industrial cloth, and also causes harm to workshop workers.
