Primer for zinc-rich epoxy resin glass sliding door and preparation method thereof

Abstract

The invention discloses a primer for a zinc-rich epoxy resin glass sliding door. The primer is characterized by being prepared from the following raw materials in parts by weight: 23-26 parts of water-based nitro resin, 45-48 parts of epoxy resin emulsions, 0.3-0.6 part of divinyl benzene, 0.3-0.5 part of flatting agents BYK-310, 0.1-0.2 part of babassu oil, 0.2-0.4 part of ethylene tar, 1-3 parts of dodecenoic acid, 0.4-0.8 part of water-based methylisothiazolinone, 0.4-0.7 part of sodium dodecyl sulfate, 0.3-0.5 part of dihexyl sulpho succinate, 0.3-0.5 part of polyether modified polydimethylsiloxane solutions, 1-2 parts of HDI curing agents E402-90T, 0.5-1.0 part of water-based silane coupling agents, 0.3-0.5 part of sodium hexametaphosphate, 0.2-0.4 part of nanometer bentonite anti-settling agents, 3-5 parts of modified nanometer titanium dioxide photocatalysts, 1-2 parts of pigments, 1-2 parts of zinc powder and 12-15 parts of deionized water. The coating disclosed by the invention not only plays roles of coloring and coverage but also plays roles of very good rust prevention, atmospheric corrosion resistance and ageing resistance through the addition of the zinc powder on the basis of having good adhesive power and high acid resistance and water resistance, and is capable of effectively purifying the air and killing multiple bacteria and has the functions of deodorization, odor elimination, pollution prevention and self cleaning through the addition of the modified nanometer titanium dioxide photocatalysts, thereby further improving the quality of the coating.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a zinc-rich epoxy resin glass sliding door primer and a preparation method thereof. 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 coatings use water as the dispersion medium, and only use a small amount of low-toxic alcohol ether organic solvents, which are safe and environmentally friendly, save resources, eliminate the risk of fire during construction, and help reduce air pollution. Water-based paint has very good adaptability to the surface of the material, and it can also be applied in a humid environment, and the coating has strong adhesion. Glass and glass products need to be coated with coatings due to the needs of aesthetics and performance. The development of glass coatings from solvent-based to water-based is an inevitable trend to meet the requirements of green en...

Problems solved by technology

However, if the nano-titanium dioxide photocatalyst is poorly dispersed in the product, it will cause agglomeration

This kind of agglomeration will directly affect the photocatalyst activity, reduce the photocatalytic ability of the product, and then lose the pollution degradation effect
