Abstract

The invention is applicable to the technical field of paint, and provides PE (polyethylene) light varnish and a preparation method thereof. The PE light varnish provided by the invention comprises the following components in parts by weight: 50-90 parts of PE resin, 10-50 parts of synthetic fatty acid resin, 0.1-0.3 part of polymerization inhibitor, 0.2-0.8 part of leveling agent, 2-10 parts of solvent, 0.1-0.5 part of defoaming agent and 0.1-0.5 part of anti-greening agent. The preparation method of the PE light varnish comprises the following steps: weighing the components of the PE light varnish, and performing mixed treatment on the PE light varnish. The PE light varnish provided by the invention has very high fullness, high gloss performance and fine coating effect. The preparation method of the PE light varnish is simple and controllable, and preparation can be completed by simply using a common dispersion machine and a vat.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a PE glossy varnish and a preparation method thereof. Background technique [0002] Nowadays, there are many kinds of paints used for wood products. As the country's environmental protection requirements for paints become more and more stringent, PE paints have also made great progress, and their applications are becoming more and more extensive. PE paint is an unsaturated polyester paint. The liquid composition can be completely transformed into a solid polymer without the release of by-products under the action of the initiator. The pollution is small, and the film is harder than the solvent-based paint, and its wear resistance , heat resistance, corrosion resistance and other aspects are equivalent to PU paint; in hardness, fullness, transparency, filling and other aspects are superior to other coatings. [0003] Due to the characteristics of the resin, the PE glossy varnish...
