Problems solved by technology

[0005] The purpose of the present invention is to propose a water-based gravure printing scratch-resistant and wear-resistant varnish applied on the surface of panel furniture paint-free overlay paper for the problem that the current solvent-based PU overlay paper cannot meet the requirements of (R2K). Oil has the advantages of high production efficiency, less VOC emissions, low energy consumption, and can solve hidden dangers of safety and fire protection in the production process

Abstract

The invention provides water-based gravure scratch-resistant wear-resistant finishing varnish applied to the surface of the paint-free veneering paper of panel furniture and a preparation method thereof. The wear-resistant finishing varnish is prepared from the following components in parts by weight: 20-50 parts of modified acrylic emulsion, 8-40 parts of a water-based high-imine melamine cross-linking agent, 2-15 parts of a water-based acrylic acid modified polyester additive, 0.5-5 parts of a cross-linking agent, 0.1-0.8 parts of a wetting agent, 0.05-3 parts of leveling agent, 0.1-1 partsof a defoaming agent, 0.5-10 parts of a wear-resistant agent, 11-35 parts of an anti-scraping agent, 0.8-4.5 parts of a catalyst, 0.2-0.90 parts of a pH regulator, 0.1-2 parts of a mildew preventive,0.1-2 parts of bactericide, 1-5 parts of ethanol, 5-25 parts of water, and 1-53 parts of a release agent. The wear-resistant finishing varnish provided by the invention has the advantages of high production efficiency, less VOC emission and low energy consumption, and can solve the potential safety hazard of fire protection in the production process.

Description

technical field [0001] The invention relates to varnish technology, in particular to a water-based gravure printing anti-scratch and wear-resistant varnish applied on the surface of panel furniture paint-free veneer paper and a preparation method thereof. Background technique [0002] At present, none of the solvent-based PU overlays provided by domestic paint manufacturers to IKEA furniture can meet the (R2K, as shown in Table 1) requirements. It is because the varnish used in the existing PU overlay paper has the problems of low scratch resistance, low production efficiency, high energy consumption, large VOC emissions and easy ignition in dry weather. [0003] Table 1 R2K standards and testing items [0004] Test items Detection method standard water 24h ≥ grade 4 Oil 24h ≥ grade 4 Alcohol 1h ≥ grade 4 coffee 1h ≥ grade 4 dry heat 70℃ ≥ grade 4 slight scratches "SB 7447+" 6N, 160 rubs ≥ grade 3 Contents ...
