Abstract

The invention relates to a high-performance environmentally friendly waterborne single-component finish paint used on a plastic substrate and a production process. The high-performance environmentallyfriendly waterborne single-component finish paint used on the plastic substrate comprises the following components in parts by weight: 60-80 parts of waterborne single-component modified acrylic emulsion, 10-20 parts of deionized water, 5-10 parts of a waterborne film-forming aid, 5-10 parts of waterborne celluloses, 0.3-0.5 part of a waterborne leveling agent and 0.1-0.2 part of a waterborne defoaming agent. The high-performance environmentally friendly waterborne single-component finish paint used on the plastic substrate has the beneficial effects that silver arrangement is good, and the advantage of good directionality of waterborne acrylic emulsion with large molecular weight is adopted. Alcohol resistance is good, the waterborne single-component emulsion with the vitrification temperature being 90 or above is adopted, the waterborne single-component emulsion is combined to nitrogen-containing fibers, and the alcohol tolerance is greatly improved. The scratching resistance is high, the vitrification temperature is high, the self-hardness of the resin with the high vitrification temperature is high, and by use of a large amount of directional wax slurry and wax powder with extinction capability, the use amount of digestion powder is greatly reduced, and therefore, the scratching resistance is qualitatively improved.

Description

technical field [0001] The invention belongs to the field of water-based paints, in particular to a high-performance, environment-friendly water-based one-component topcoat for plastic substrates and a production process. Background technique [0002] The successive implementation of the "Environmental Protection Law" and the "Air Pollution Prevention and Control Law" has forced enterprises to strictly abide by the amount of VOC emissions and reduce the degree of pollution to the environment. The original water-based single-pack topcoat has deficiencies such as poor silver displacement, poor alcohol resistance, and poor scratch resistance. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a high-performance environmental protection water-based one-component topcoat and production process for plastic substrates. [0004] The purpose of the present invention is accomplished through the follo...
