Abstract

The invention discloses a water-based paint for coating an automobile frame. The water-based paint comprises the following components in percentage by weight: 20%-30% of silicone acrylic emulsion, 10%%-15% of color pigment, 5%-10% of a modifier, 15%-25% of a composite filler and 40%-50% of water, wherein the color pigment comprises 2%-5% of ferromanganese black, 6%-9% of calcium chloride and 1%-2% of methylbenzene; the composite filler comprises 2%-5% of magnesium phosphate, 10%-15% of calcium carbonate and 2%-3% of polyorganosiloxane. The water-based paint has the advantages that the corrosion problem of the water-based paint can be effectively solved by adopting butyl acrylate, polyoxyethylene ether, potassium carbonate and deionized water to a certain extent, the film-forming effect is enhanced by using glycol phenyl ether as a film-filing aid, the curing speed is also greatly improved by matching with other components of the modifier, the coating effect on the automobile frame is relatively good, the service life is prolonged, and the water-based paint is suitable for popularization.

Description

technical field [0001] The invention relates to a water-based paint, in particular to a water-based paint used for painting automobile frames. Background technique [0002] Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. Water-based paints include water-soluble paints, water-diluted paints, and water-dispersible paints (latex paints). Water-soluble coatings use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. [0003] At present, there are many kinds of water-based coatings used in automobile frames, and the commonly used water-based coatings have not reached the ideal state in terms of film formation and curing rate. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a water-based pain...
