Abstract

The invention discloses unsaturated polyester resin with solid content being 100% and a preparation method thereof, and a low-VOC odor-free PE varnish produced from the unsaturated polyester resin and a preparation method thereof. The low-VOC odor-free PE varnish comprises: the unsaturated polyester resin with solid content being 100%, low-odor active monomers, a food-grade antioxidant, a flatting agent, a defoamer, and an anti-sagging aid. The PE varnish is low in VOCs and has very low odor during construction, has the property of forming a thick paint film in one time just like conventional unsaturated polyester paint, has good pore-seal property, has high fullness, is wear-resistant, has high glossiness, etc.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an unsaturated polyester resin with a solid content of 100%, and to a low-VOC clean-odor PE varnish prepared from the unsaturated polyester resin with a solid content of 100%. Background technique [0002] PE paint, that is, unsaturated polyester paint, is cured by blending the main agent, accelerator and initiator to carry out polymerization bridging reaction. The solvent is styrene, which participates in the reaction when forming a film. Compared with other solvent-based wood paints, the advantage of PE paint is that it has "100% reactivity", which means that the liquid composition can be completely transformed into a solid polymer without the release of by-products under the action of the initiator. . However, other solvent paints need a large amount of solvent to volatilize before forming a paint film. Such a paint film is not as hard as resin curing, and the volatilization of solven...
