Abstract

The invention relates to the coating field, and particularly relates to a special paint for environmental-friendly water-based shield pump and its preparation and using method. The special paint for an environmental-friendly water-based shield pump is prepared from, by mass percent, 60-70% of aqueous dispersion of solid bisphenol A epoxy resin, 0.25-0.75% of antifoaming agent, 1.1-1.95% of dispersing agent, 0.78-1.23% of film forming assistant, 0.21-0.79% of wetting agent, 1.21-2.79% of antiflash rust agent, 5.35-7.89% of titanium dioxide, 2.23-5.36% of organic pigment, 1.43-2.07% of barium sulfate, 0.22-0.69% of inorganic pigment, 0.31-0.57% of thixotropy anti-settling agent, 0.53-1.38% of thickening agent, and 15-23.5% of deionized water. The special paint is prepared by mixing and stirring. The VOC content is not more than 85g / L; the special paint is featured by small odor, environmental-friendly, salt mist resistance, strong water resistance, high hardness, strong impact resistance, and good storage stability.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an environment-friendly water-based special paint for canned pumps and methods for preparing and using the same. Background technique [0002] In recent years, the rapid rise and growth of canned pump production industry has also led to the development of canned pump coatings. Our country is a large industrial country, there are many large and small factories, and the products they produce are countless. In order to make the products have a longer service life, the surface coating is the most critical factor. The canned pump adopts the integrated structure of the motor and the water pump, all of which are statically sealed, so that the electric pump is completely leak-free. This fully-enclosed, leak-free structure allows it to transport some toxic and harmful liquid substances. Corrosion and rust are particularly important. Aiming at the broad application market of canned pu...
