Problems solved by technology

[0003] In traditional water-based varnish, the binding force of the coating film to the wax emulsion particles is too small or too rigid, which will cause the wax emulsion particles to fall off during the friction process, which will eventually lead to a decrease in the wear resistance of the water-based varnish. Adding too much wax emulsion will also cause Gloss reduction
Because the wear resistance of traditional water and oil can not achieve the ideal effect, while taking into account the wear resistance, the gloss is not good, resulting in the reduction of post-press processing suitability
[0004] Chinese patent CN104946115A discloses a fast-drying wear-resistant water-based varnish and its preparation method, using silicic acid alcohol wear-resistant resin, water-based polyurethane resin and water-based paint wear-resistant accelerator, etc. to prepare wear-resistant water-based varnish, although The wear resistance has been improved, but the production cost will increase accordingly

Abstract

The invention discloses high wear resistance water-borne gloss oil, comprising the following components with the contents in percent by weight: 0-25.0% of acrylic emulsion A, 25.0-45.0% of acrylic emulsion B, 15.0-60.0% of elastic emulsion, 4.0-8.0% of wax emulsion, 0.1-0.5% of defoaming agent, 0.5-1.5% of wetting agent and 0-5.0% of coalescing agent. The invention further provides a preparing method of the high wear resistance water-borne gloss oil, and mainly adopts a method of adding the materials step by step to prepare the high wear resistance water-borne gloss oil. The water-borne gloss oil prepared by adopting the method has higher wear resistance, and has the advantages of high gloss, good flexibility, fastness in drying, good anti-adhesion property and excellent online performance.

Description

technical field [0001] The invention relates to the field of macromolecular materials, in particular to water-based varnish used in coating industry, flexible packaging and other industries and a preparation method thereof. Background technique [0002] The wear resistance of water-based varnish is mainly provided by the wax emulsion. The particle size of the wax emulsion is on the same order of magnitude as the thickness of the coating film. During the film formation process, the floating effect of wax is generated, so that the wax floats to the top layer of the coating film and is wrapped with varnish. In the resin, and partially exposed on the outside of the coating film; when the surface of the coating film is subjected to external force, due to the sliding effect of the wax protective layer, the damage of the external force to the coating film surface is weakened. [0003] In traditional water-based varnish, the binding force of the coating film to the wax emulsion part...
