Glaze coloring agent for waterborne woodenware coating and preparation method thereof

Abstract

A glaze coloring agent for waterborne woodenware coating and a preparation method thereof belong to the coating field. The coloring agent comprises a color-spreading component and a color-fixing component. The color-spreading component comprises amphiphilic polymer resin which has the effect of pigment loading and bonding, and can allow the pigment to spread and penetrate on a wood surface; the color-fixing component comprises acrylate polymer which has excellent color retention and weatherability. The coloring agent of the invention can provide proper open time for construction, can be rewiped, is easy for color modification, has good color retention for recoating, does not cause floating color or loose color, has good compatibility and interlayer binding force with various waterborne priming paint and top finish, and can well improve the wood-grain contrast of a wood surface; with the matching application of various waterborne woodenware coating processes, the coloring agent has thecharacteristics of safety and environmental protection, no irritant smell, uniform coloring, plump filling, and excellent color fixing; by adjusting the ratio of the color-spreading component and thecolor-fixing component, the coloring agent is applicable to waterborne coloring and American antique coating processes of various wood furniture products.

Description

Technical field: [0001] The invention relates to a kind of Grace stain eraser for water-based woodware coating and a preparation method thereof. Background technique: [0002] Water-based wood coating is a coating product that is painted on the surface of wooden furniture or wood products. In addition to its protective effect on wood products, it also needs to have a certain decorative effect. In the coating process of water-based wood coatings, the American coating process occupies a very important position. American-style coating is an open coating. By deepening the contrast of wood grains and enhancing the sense of layering and three-dimensionality of the wood surface, the natural patterns of the wood are fully highlighted, bringing a natural and beautiful texture to the furniture. American-style painting is also called antique painting. By cooperating with some special plate treatment and color rubbing techniques such as old-fashioned, wormhole, and damaged treatment, i...

Problems solved by technology

Alkyd resin color wiper, such as patent CN 101472686A, needs to add diluent during use, which will cause adverse effects on the health of construction workers; for non-drying vegetable oil products and their water-based modified products, although the color development effect It is better on patents such as CN1810898A, CN101608079A, CN101386726A, but there are slow drying, poor color fixation and color retention, and poor compatibility with water-based paints, which cannot be well combined with water-based primers or water-based topcoats. Problems such as cross-color and flowering are prone to occur during painting

In addition, there is a kind of emulsion-type alkali-soluble multi-stage resin used for translucent coloring, as described in patent CN1090290A, which has problems such as poor color development and swelling wood surface, and it is difficult to meet higher decorative requirements.
