Problems solved by technology

[0003] The existing PE primers all need to use organic cobalt as a reaction accelerator. After a period of time, the divalent cobalt ions existing in the molecules are oxidized to trivalent cobalt ions, resulting in discoloration of the paint film.
Existing technology only replaces the accelerator but the effect is not obvious
[0004] In response to this situation, we have developed a PE primer resin with excellent anti-greening properties to be used in PE wood furniture paints, which can change the shortcomings of traditional PE resins to make PE primers with poor anti-greening properties, and can better meet the needs of furniture companies.

Abstract

The invention relates to the field of paint, and provides an anti-greening PE (polyethylene) primer and a preparation method thereof. The PE anti-greening primer provided by the invention comprises the following components in parts by weight: 70 parts of resin, 3 parts of styrene, 0.5 part of anti-greening modifier, 0.4 part of dispersing agent, 1 part of anti-settling agent, 20 parts of talcum powder, 5 parts of zinc stearate, 0.3 part of defoaming agent and 0.3 part of leveling agent. Compared with the prior art, the PE primer provided by the invention has a favorable film coating effect and excellent anti-greening performance and can be widely used for furniture painting.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an anti-greening PE primer. Background technique [0002] The curing reaction of unsaturated polyester is a free radical copolymerization reaction. During the curing reaction, an initiator (white water) and an accelerator (blue water) need to be added. Through the redox reaction, the cobalt salt in the accelerator decomposes the initiator to produce high Active free radicals, free radicals attack the unsaturated double bonds in the polyester molecular chain and the cross-linking monomer styrene to activate them, so that a cross-linking reaction occurs, and the polyester forms an excellent paint film with a three-dimensional network structure. In order to improve the sandability, it is generally necessary to increase the amount of blue water and white water to shorten the construction time and improve production efficiency, which will turn the paint film color green and affect the appearan...
