Abstract

The invention relates to liquid for strengthening the corrosion resistance of waterborne coating pigment for wheel hub spraying and a preparation method of the liquid. The liquid is prepared from the following ingredients: cotton linters, a preservative, a mixed solvent for defoaming and decontaminating, an anti-mildew bactericide, a viscosity reducer, a surface modifier, a metal ion chelating agent, a corrosion inhibitor, water, corn starch, an acrylic acid-APEG-sodium p-styrene sulfonate terpolymer, a naphthalene sulfonic acid-styrene-maleic acid terpolymer, monochloroacetic acid and polyacrylamide. The beneficial effects are that dispersive liquid can be utilized to enable the coating to emulsify a coating prepared from film forming matter, solvent type resin is dissolved in an organic solvent, then with the help of an emulsifying agent, the resin is dispersed in the water to form emulsion through strong mechanical agitation, the dispersibility of the waterborne coating pigment is enhanced, meanwhile, the surface tension is increased, so that the latent heat of evaporation is great, and the pigment is greatly influenced by temperature and humidity; the dispersive stability is good, and the anti-shearing force performance is better; and the electrical conductivity is good, and the corrosivity is high.

Description

Technical field: [0001] The invention relates to an ordinary aluminum alloy wheel hub, in particular to a liquid for enhancing the corrosion resistance of water-based paint pigments used in wheel hub spraying and a preparation method thereof. Background technique: [0002] With the rapid development of the automobile industry, the requirements for energy saving and consumption reduction of modern automobiles are constantly increasing, safety and environmental protection regulations are becoming stricter, and the requirements for automobile lightweight are more urgent. Due to the wide use of aluminum alloy wheels, its beautiful, atmospheric and changeable shape design also adds a lot to the car. At present, in the Chinese auto market, the utilization rate of aluminum alloy wheels for cars has reached at least 70 shares of the total car market. According to relevant statistics, in 2003 this proportion was about 50 copies. Aluminum alloy is light in weight, high in strength, ...
