Problems solved by technology

The two-component water-based paints that have been developed at present mainly include two-component water-based polyurethane (PU) and two-component water-based epoxy two major categories of products, but both are difficult to popularize. The first reason is that the cost is high and the raw materials are difficult to obtain; the reason The second is that the construction is very inconvenient. The curing agent itself is o

Abstract

The invention provides a metal cross linking molecular film formation and two-component waterborne wood lacquer and a preparation method thereof. The waterborne wood lacquer consists of a component A and a component B; the component A is the main paint, consisting of components with the weight portion of water-soluble waterborne additive of 55 to 98 shares, waterborne additive of 0.5 to 10 shares, film forming additive of 0 to 13 shares, pigment or filling of 0 to 44 shares; the component B consists of cross linking agent containing multivalent metal ions. The preparation method consists of the steps: 1. water soluble waterborne resin is prepared; 2. the main paint of component A are prepared; 3. the main paint of component A and the cross linking agent of component B are mixed, so as to obtain the waterborne wood lacquer. The preparation method of the invention is simple and convenient, the formulation cost and the production cost are lower, and the main raw material is stable in price and readily available. The film hardness, fullness, anti-high temperature back viscous, water resistance, grind ability, drying capacity, etc. of the obtained product are improved greatly, the cost of production is lowered and the T toleration of construction and the maneuverability are improved. The external condition is also characterizes by solvent woodenware coating.

Description

technical field [0001] The invention relates to the technical field of chemistry and chemical engineering, in particular to a water-based wood varnish and a preparation method thereof. technical background [0002] As a class of important surface beautification and protection decoration materials, wood lacquers are widely used in people's lives. However, traditional wood paints are basically solvent-based paints, such as polyurethane paints, nitro paints, alkyd paints, etc., which contain a large amount of volatile organic solvents, which will produce many toxic and irritating substances during the production and use of paints. Some organic compounds also contain strong carcinogens such as benzene, formaldehyde, and free TDI, which have caused serious harm to people's health and the surrounding environment. [0003] With the development of the society, the prosperity of the economy and the improvement of living standards, people are more concerned about their own health, an...
