Problems solved by technology

[0004] Therefore, in view of the fact that the existing self-deposition coatings need reactive water washing to improve performance, and in order to ensure the quality of the bath solution of reactive water washing, regular overflow of water washing after self-deposition is required, which brings greater sewage treatment pressure, and the wet film is dried For the defects of segmented drying and high drying temperature, a PVDC type self-deposition coating that does not require reactive water washing and is dried in a single stage at low temperature, its preparation method and application

Abstract

The invention discloses auto-deposition coating based on PVDC resin serving as a main material as well as a preparation method and application of the auto-deposition coating, which belong to the technical field of metal coating. The auto-deposition coating is prepared from PVDC resin, SBR resin, waterborne wax, emulsifier, film forming additive, flatting agent, moisturizing agent, dispersing agent, color paste and defoaming agent. A degreased and pickled steel-iron base material workpiece is immersed in an auto-deposition working solution to react, a uniform resin coating layer is formed, thecoating layer has certain washability and wet membrane adhesion, and after being washed and dried, the resin coating layer has corrosion resistance equivalent to ordinary electrophoretic primer. The auto-deposition coating based on the PVDC resin has the advantages of simple process, no need of phosphorization, no heavy metal ion passivation, no reaction washing, low treatment temperature, low cost, and short construction and production line.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment and metal coating, and in particular relates to a self-deposition paint based on PVDC resin as the main material and its preparation method and application. Background technique [0002] Self-deposition paint is a kind of full-immersion water-based paint that automatically covers the surface of steel substrates through chemical reactions without electricity. The remarkable feature of the coating is that the performance of the coating film directly deposited on the surface of the steel substrate can be close to that of cathodic electrophoretic coating without phosphating pre-treatment. The self-deposition coating is composed of resin, pigment, oxidant, acid and water. Through the chemical action of the micro-battery formed by the steel substrate in the acid solution, the latex particles in the self-deposition coating in the solution are demulsified and attached to the steel. , and ...
