Anti-greening PE (Polyethylene) transparent primer and preparation method thereof

Abstract

The invention discloses an anti-greening PE (Polyethylene) transparent primer. The anti-greening PE (Polyethylene) transparent primer comprises the following components according to the percentage content: 50-80% of unsaturated resin, 0-1% of polymerization inhibitor, 0.1-1% of deforming agent, 0.1-0.5% of wetting dispersion agent, 0.1-0.6% of anti-settling agent, 0-6% of zinc powder, 0-30% of transparent powder, 0-5% of talcum powder, 0.1-1.3% of flatting agent and 0-5% of solvent. Simultaneously, the invention also discloses a preparation method of the anti-greening PE transparent primer. The anti-greening PE (Polyethylene) transparent primer prepared by using the components according to the preparation method effectively solves the greening phenomenon of the PE paint film of the prior art, takes on light red, and is close to a base material in color; and the transparency of the paint film of the transparent primer is increased.

Description

technical field [0001] The invention relates to the technical field of solvent-based wood lacquer coatings, in particular to an anti-greening PE transparent primer. At the same time, the invention also discloses a preparation method of the transparent primer. Background technique [0002] PE paint, that is, unsaturated polyester paint, which is generally composed of three components of main agent, initiator and accelerator, has the advantage of "100% response ability", and its solid content can be close to 100%, which can reduce solvent The pollution caused by volatilization to the environment, PE paint is in line with the direction of future coating development. However, due to the influence of the blue water of the accelerator in the existing PE paint, the paint film is prone to greening, which causes the PE transparent primer paint film to be greenish and dark, which affects the wood grain clarity of the substrate. Compared with the white primer Generally speaking, becau...

Problems solved by technology

However, due to the influence of the blue water of the accelerator in the existing PE paint, the paint film is prone to greening, which causes the PE transparent primer paint film to be greenish and dark, which affects the wood grain clarity of the substrate. Compared with the white primer Generally speaking, because the greening affects the whiteness of its paint film, it has a certain impact on its construction performance. Therefore, the greening problem has become a common and difficult problem in PE paint.

[0003] At present, there are two main methods to solve the greening problem of PE paint: one is to choose raw materials that have little effect on the greening of the paint film, and the other is to reduce the degree of greening through anti-greening agents, but the above methods can only be used to a certain extent Weakening the trend of paint film greening does not completely solve the problem of paint film greening
