PE whitening-resistant transparent priming paint

Abstract

The invention discloses a PE whitening-resistant transparent priming paint. The PE whitening-resistant transparent priming paint comprises the following components in parts by weight: 30-70% of air-dried unsaturated polyester resin, 3-10% of acrylic acid ester, 0.01-2% of an antifoaming agent, 0.01-2% of a dispersant, 10-35% of a filling material, 0-2% of a wetting agent, 0.01-2% of a rheological auxiliary agent, 0.01-2% of a wax auxiliary agent, 0.01-2% of a hand feeling auxiliary agent, 0.01-2% of a thickening agent, and 5-10% of a solvent. The PE transparent priming paint makes a paint film to have better fullness, hardness, high chemically-resistant performance, strong whitening resistance, and excellent transparency. VOC volatilization is far lower than a national standard 420 mg / l, the PE transparent priming paint has low excitant smell, can effectively solve the problem that the product is severely influenced by whitening of a woodwork at anaphase, the PE transparent priming paint has excellent greening on a light color wood base material, and can satisfy the high environmental protection, low smell, and low pollution requirements for consumers.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a PE anti-whitening transparent primer. Background technique [0002] In wood coatings, PE wood coatings account for an increasing proportion of wood home improvement coatings because of its high solid content, high hardness, excellent collapse resistance, good filling, high fullness, and time-saving, labor-saving, and cost-saving construction. But at present, many PE transparent primers have the problem of whitening and fogging in the later stage; and because the drying process of PE paint requires blue and white water, resulting in the problem of greening, so the use of PE primers on light-colored solid wood is limited; PE primers A large amount of styrene is often added to the paint to participate in curing and cross-linking, so there is a strong pungent smell during the construction process, which has a serious impact on the health of the builders.

Problems solved by technology

[0003] In view of the above-mentioned technical defects, the technical problem to be solved in the present invention is to improve the problem of whitening of the PE transparent primer in the later stage, and at the same time, it is necessary to solve the problem of serious greening of the PE transparent primer, which affects the true color of the substrate, and the PE primer construction process. big smell problem

Even if the most used high-efficiency leveling agents are used to obtain good slipperiness and improve scratch resistance, the leveling agent alone is far from enough, and other additives are needed to meet the various needs of the paint film. At the same time, it is necessary to use film-forming aids to solve the problem of oxygen inhibition in unsaturated air-drying systems
