Problems solved by technology

[0002] At present, when the unsaturated polyester primer in the paint market is applied to the fiberboard substrate, the PU sealing primer must be applied first, and then the UPE unsaturated polyester primer can be sprayed after being polished after hard drying; the construction process of this spraying method is complicated, time and The cost increases, and the adhesion and fullness are not good, which greatly reduces the construction efficiency
If the existing unsaturated polyester primer is directly sprayed without PU sealing primer and sanding treatment, there will be defects such as poor adhesion of the coating film, easy paint peeling, and no fullness

Abstract

The invention relates to an aldehyde-ketone resin modified unsaturated polyester primer and a preparation method thereof. The aldehyde-ketone resin modified unsaturated polyester primer is prepared by mixing a main paint, an initiator and an accelerator at a weight ratio of 100:(1.0-1.5):(1.2-1.7), wherein the main pain is prepared from the following components in parts by weight: unsaturated polyester resin, a dispersing agent, hydroquinone, a defoaming agent, a leveling agent, a toner, heavy calcium carbonate, talc powder, fumed silica, zinc stearate, aldehyde-ketone resin solution and styrene, the accelerator is cobalt naphthenate, and the initiator is methyl ethyl ketone peroxide. The aldehyde-ketone resin modified unsaturated polyester primer prepared by adopting the preparation method can be directly sprayed on the substrate of a fiberboard without the necessity of polishing the substrate, and the aldehyde-ketone resin modified unsaturated polyester primer presents excellent adhesion and fullness after being sprayed on the substrate of the fiberboard.
