Abstract

The invention provides high-gloss environment-friendly quick-drying low-odor water-based oil polish and a preparation method thereof. The high-gloss environment-friendly quick-drying low-odor water-based oil polish is prepared from, in percentage by weight, 81-85% of water-based polycarbonate resin, 4-6% of highly concentrated alcohol, 2-4% of deionized water, 1-2% of a wetting flatting agent, 0.5-1% of a defoaming agent, 2-3% of an associative thickener and 2-3% of high-gloss wax emulsion; according to the invention, a highly concentrated alcohol solvent with low reaction residue is selected, polycarbonate resin with fast water release is selected as matrix resin, a highlight wax emulsion with good scratch resistance and no influence on gloss is selected, a reasonable formula proportion is adopted, and no solvent harmful to human body is added in the production process, thus the drying speed of the oil polish under the infrared light is improved, the VOC emission is substantially reduced, the product odor is reduced, and the water-based oil polish has characteristics of good wear resistance, high color, rapid drying and low residual odor, can be printed on the product so as to increase the aesthetic degree and the friction resistance of the product, and can improve the environmental protection degree.

Description

technical field [0001] The invention belongs to the technical field of polymer ink, and in particular relates to a high-gloss, environment-friendly, quick-drying and low-odor water-based varnish and a preparation method thereof. Background technique [0002] Glazing oil refers to a liquid that is coated on the surface of printed matter to increase gloss, abrasion resistance and water resistance. Varnishes include water-based varnishes, oil-based varnishes, UV varnishes, and solvent-based varnishes. At present, water-based varnish is the most widely used in China, because it has very good environmental protection performance. However, existing water-based varnishes have the defects of slow drying, high odor and low gloss, so it is urgent to research and invent new products to solve the above problems. Contents of the invention [0003] The present invention aims to solve the defects of the existing water-based varnishes such as slow drying, large odor and low gloss, and p...
