Abstract

The invention relates to the technical field of paint preparation, in particular to waterborne paint for car chassis protection and a preparation method thereof. The waterborne paint comprises water-soluble epoxy acrylic resin, polyacrylate emulsion, zinc isoocatanoate, sodium alginate, hexamethylene diisocyanate, nano silicon carbide, talcum powder, hydroxyethyl methacrylate phosphate, tourmalinepowder, anion powder, antirust pigment, a dispersing agent, a film forming agent, a levelling agent, a defoaming agent and deionized water. The waterborne paint and the preparation method thereof have the advantages that the prepared paint is good in corrosion resistance; the hydroxyethyl methacrylate phosphate, the epoxy acrylic resin and the hexamethylene diisocyanate are allowed to have crosslinking reaction under the effect of potassium persulfate to generate a stable three-dimensional network structure, the hydroxyethyl methacrylate phosphate, the epoxy acrylic resin and the hexamethylene diisocyanate are connected through covalent bonds, the adhesive force of the paint to metal is evidently enhanced by grafting the hydroxyethyl methacrylate phosphate, and paint film falling off canbe reduced.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a water-based paint for automobile chassis protection and a preparation method thereof. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The authoritative book "Painting Technology" in the Chinese coatings industry defines: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a solid adhesion, a certain strength, and a continuous state. Thin film. The film formed in this way is commonly called coating film, also known as paint film or coating.” In the early days, most of the paints used vegetable oi...
