Problems solved by technology

However, these two systems have poor permeability to wood. The emulsion synthesis needs to consume a large amount of organic monomers, and still relies on petroleum industry products. In addition, most of the water-based polyurethane emulsion synthesis processes use solvents such as acetone and NMP. The later solvent removal process is complicated and expensive.

Abstract

The invention relates to a water-based environment-friendly modified alkyd wood paint. The film forming matter is a modified alkyd emulsion which accounts for 50-80 wt% of the water-based wood paint; and the wood paint also comprises a dispersing agent, a wetting agent, a defoaming agent, a thickener, a pH regulator and the like. The modified alkyd wood paint can effectively enhance the permeability of the coating for the substrate, and can also use recyclable biological resources in wood paint industry, thereby reducing the environmental pollution and lowering the production and application cost. The modified alkyd wood paint has the characteristics of easy construction, plump coating and favorable decoration property in the alkyd paint, improves the characteristics of low-temperature quick drying (can quickly form a film at 0 DEG C without any film-forming assistant or cosolvent), yellowing resistance, wear resistance, water resistance and the like in the paint film, and has environment friendliness and economical efficiency.

Description

technical field [0001] The invention relates to a water-based environment-friendly modified alkyd wood paint coating, which belongs to the technical field of polymer chemistry and polymer coatings. Background technique [0002] The solvent-based wood paint used in furniture manufacturing and home decoration produces a large amount of organic volatiles in the production and coating process, which is extremely harmful to human health and causes environmental pollution. With the improvement of environmental protection regulations and the continuous enhancement of environmental protection awareness, the introduction of non-toxic and cheap water into coatings can not only save resources, reduce costs, but also reduce VOC emissions, which makes water-based wood coatings more and more popular among consumers. Favored and valued by the market. [0003] At present, water-based wood lacquers mainly include water-based acrylic and polyurethane systems in the market. However, these tw...
