Abstract

The invention relates to a sanding-free unsaturated polyester primer applicable to melamine substrates and a preparation method thereof. The sanding-free unsaturated polyester primer applicable to melamine substrates is prepared by mixing the following components in parts by weight: 100 parts of main paint, 1.0-1.2 parts of initiator and 1.2-1.4 parts of accelerator. The main paint is prepared from an unsaturated polyester resin, a dispersing agent, hydroquinone, a defoaming agent, a leveling agent, rutile titanium white, ground calcium carbonate, talcum powder, gas-phase silicon dioxide, zinc stearate, an adhesion enhancer and styrene; the accelerator is cobalt naphthenate; and the initiator is methylethyl ketone peroxide. The sanding-free unsaturated polyester primer applicable to melamine substrates can be directly sprayed without sanding the substrate when being applied to the melamine substrate, and has excellent adhesive force and fullness after being sprayed.

Description

technical field [0001] The invention relates to a coating for furniture, in particular to a non-grinding unsaturated polyester primer applied to melamine substrates and a preparation method thereof. Background technique [0002] At present, the development of unsaturated polyester furniture paint is very rapid, especially in the decorative coating of furniture such as kitchen cabinets, bathrooms, and display cabinets. Among the white unsaturated polyester primers on the market, none of them can be sprayed directly without grinding White unsaturated polyester primer for melamine substrates. The existing white unsaturated polyester primers on the market are used on melamine substrates, and the substrates must be fully ground before they can have good adhesion. [0003] If the existing white unsaturated polyester primer is directly sprayed on the non-polished melamine substrate, not only will there be defects such as poor adhesion of the coating film and easy paint peeling, bu...
