Abstract

The invention relates to a polyacrylic ester wood lacquer emulsion and a preparation method thereof. The emulsion comprises a monomer composition, a silicon-containing unit prepolymer, an emulsifying agent, an evocating agent and deionized water. The polyacrylic ester wood lacquer latex is prepared by introducing the silicon-containing unit to the process of emulsion polymerization of monomers such as acrylic acid and acrylic ester type and the like in a simple manner; the technical process of the polymerization way is quite simple, and the preparation cost is relatively low; in addition, during film forming of the emulsion, low surface energy silicon-containing resin can be shifted to paint film surface; as a result, atoms on the paint film surface can be arranged in a compact manner to form a self-stratification structure.

Description

technical field [0001] The invention relates to a polyacrylate wood paint emulsion and a method for synthesizing the emulsion. Background technique [0002] Water-based wood lacquer is a kind of wood surface decoration with water as diluent. This kind of paint does not contain organic solvents such as benzene, toluene, xylene, formaldehyde and toxic heavy metals such as free TDI. It is a pollution-free high-quality wood decoration. . In the prior art, water-based wood paints are mainly divided into three categories: water-based polyurethane (PU), water-based acrylate (PAC), and composites of water-based polyurethane and water-based acrylate. [0003] Among them, although water-based polyurethane wood coatings have the advantages of good appearance, high hardness, excellent flexibility, wear resistance, and weather resistance, the solid content of this coating is low, generally only about 30%, and the price is relatively high. High, relatively poor water resistance, and usu...
