CN102533026A - Waterborne varnish special for pine - Google Patents

Abstract

The invention relates to waterborne varnish special for a pine, which comprises water-based acrylic resin, an antifoaming agent, a wetting dispersant reagent, a base-material wetting agent, a matting powder, a film-forming assistant agent, a thickening agent, water, a preservative, a mildew-proof agent and a hand-feeling additive. The special top-coat paint used for water-based pines effectively overcomes the defects in the prior art that as the closure property of the waterborne wood varnish used for pines is poor, the waterborne wood varnish turns yellow over time, and the local adhesive force is not good.

Description

A kind of water-based pine clear finish that is exclusively used in

Technical field

The present invention relates to a kind of working method of water-based pine clear finish, especially be specifically designed to the single-component water-based woodware varnish on the pine.

Background technology

Pine is with its simple and unadorned texture, lifelike texture, pure beautiful color and luster are used for making children furniture more, and pine furniture has satisfied people to the moulding and pursuing of physical environment, and is just constantly accepted by the human consumer.Yet conventional oil paint is unfavorable for children's physical and mental health owing to the release of its a large amount of solvent, is not suitable for application on pine furniture.And see on the market some be used for the aqueous woodware paints on the pine because its closure is not good, phenomenons such as yellowing, local sticking power be bad will appear in time one length.

Summary of the invention
