Problems solved by technology

[0003] However, there are still many problems with the traditional water-based wood varnish. First, the adhesion between wood and wood is not good enough to meet the requirements of rapid coating of water-based wood. Secondly, the painted wood contains acid substances such as tannins. , it is easy to make the wood discolored and blackened; finally, the water-based wood paint repairing varnish is prone to agglomeration and precipitation, which affects the effect of wood paint repairing

Abstract

The invention relates to the technical field of water-borne gloss oil, and particularly relates to water-borne wood lacquer color-repairing gloss oil, as well as a preparation method and an application thereof. The gloss oil is prepared from the following raw materials: water-soluble polyurethane resin, water-soluble acrylic resin, dipropylene glycol methyl ether, polyethylene imine, a water-bornedefoaming agent, a water-borne flattening agent, ethanol, a dispersant and deionized water. The preparation method comprises the following steps: a, mixing the components under a norm-temperature condition, and stirring for 20-25 minutes; and b, filtering with a filter screen having 300 meshes after uniform stirring. The water-borne wood lacquer color-repairing gloss oil is prepared by using transparent resin as components, and is easy in color matching in the using process; the polyethylene imine synthesized with the dipropylene glycol methyl ether in the raw materials can be used for effectively improving the adhesion performance of the water-borne wood lacquer color-repairing gloss oil, has strong binding force with a wood surface; and the polyethylene imine can react and bind with tanning and other acid substances in a wood material, so that the problems of discoloring and blackening of woods can be effectively relieved.

Description

technical field [0001] The invention relates to the technical field of water-based varnish, in particular to a water-based wood paint repairing varnish and a preparation method and application thereof. Background technique [0002] Environmental protection and energy are two major challenges we face in the 21st century. In order to meet this challenge, the wood coating industry is gradually changing from traditional solvent-based coatings with high energy consumption and high pollution to environmentally friendly and resource-saving water-based coatings. Compared with solvent-based varnish, water-based varnish is mainly composed of three major categories: main agent, solvent, and auxiliary agent. It has the characteristics of colorless, odorless, strong transparency, non-toxic, no organic volatiles, low cost, and wide sources. Therefore, it is widely used in the field of decoration design wood lacquer and wood product manufacturing. The additives added can also make the sol...
