Problems solved by technology

[0002] At present, most of the paint additives on the market have a single function. In order to meet the comprehensive performance standards of a complete coating, a variety of functional additives are often introduced into the formula such as adhesion promoters, acid catalysts, adhesives, anti-flash corrosion agents, etc. The more types of these additives are used, the higher the cost of the paint, the stability of the paint will also decrease, and the complexity of the formula will be increased, making the paint production process cumbersome and easy to omit and add raw materials due to human factors.

Abstract

The invention discloses a multifunctional accelerant for amino baking paint. The multifunctional accelerant for the amino baking paint is mainly prepared from the following raw materials: epoxy resin,phosphoric acid compounds, glycidol aliphatic compounds and organic solvents. The accelerant has high water solubility and high compatibility with resin, can improve the wetting property of the coating, can accelerate the curing reaction of the resin and the amino resin, can be crosslinked with the amino resin, and improves the solvent resistance and the adhesive force of the coating; and the aidand a metal base material form one layer of compact phosphating film, so that the water tolerance and the flash erosion resistance of the coating are enhanced. The invention also discloses a preparation method of the multifunctional accelerant for the amino baking paint.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a multifunctional accelerator for amino baking varnish and a preparation method thereof. Background technique [0002] At present, most of the paint additives on the market have a single function. In order to meet the comprehensive performance standards of a complete coating, a variety of functional additives are often introduced into the formula such as adhesion promoters, acid catalysts, adhesives, anti-flash corrosion agents, etc. The more types of these additives are used, the higher the cost of the paint, the lower the stability of the paint, and increase the complexity of the formulation, making the paint production process cumbersome and prone to omissions and wrong addition of raw materials due to human factors. [0003] In view of the above problems, the development of a multifunctional additive with several in one effects will have certain commercial value,...
