Abstract

The invention relates to water-based antirusting paint operable with rust and the method for preparation. The water-based paint contains talcum powder, iron oxide red, phosphoric acid, CF-01 non-ionic humectant, P-19 polyacrylic sodium salt disperser, aluminium tropolyphosphate, self crosslinking acroleic acid emulsion, erinitrit and water added up to 100% (weight). The method for preparation is as following: mixing by homogenizer match said P-19 polyacrylic sodium salt disperser, CF-01 non-ionic humectant, talcum powder, iron oxide red, aluminium tropolyphosphate, and erinitrit, then sending the mixture to sand mill and sanding to prepare the serum of a fineness less than 60 micrometre, adding self crosslinking acroleic acid emulsion and phosphoric acid to the serum and mixing thoroughly, and filtering to prepare the product. It has a characteristic of no-containing of toxic and heavy metal, drying quickly, operable with rust, and corrosion-preventive property nice.

Description

technical field [0001] The invention relates to a water-based anti-rust coating with rust, and also relates to a preparation method of the coating. Background technique [0002] Traditional low-solid solvent-based epoxy antirust primers contain about 50% organic solvents. The price of these organic solvents is becoming more and more expensive with the shortage of energy sources such as oil, and they are discharged into the atmosphere during the manufacturing and construction stages of coatings, polluting the environment and endangering human health. With the development of the economy and the improvement of the quality of human life, people's calls for protecting their own living space are getting higher and higher, and environmental protection regulations are becoming more and more stringent. The strengthening of environmental regulations restricts the application of heavy metal pigments such as lead and chromium in paints. Traditional water-based antirust primers with ru...
