Aqueous acrylic acid series wooden ware sealing paint and method for preparing special emulsion thereof

The invention relates to aqueous acrylic acid series wooden ware sealing paint and a method for preparing special emulsion thereof. Nano emulsion with small particle diameter and narrow distribution is prepared by using an acrylic acid monomer containing multiple polar groups as a raw material. Multiple aids are added into the emulsion serving as a basic film-forming substance to form the novel aqueous wooden ware sealing paint. The polar functional groups on polymer molecule chains have good wetting property on wood, emulsion particles are easy to permeate into wood fiber conduits and quickly form films in conduit holes, and the paint can effectively prevent the moisture in the aqueous wooden ware paint from permeating into the wood and solves the problem of surface gully caused by the water-swelling wood; and meanwhile, the paint also can effectively seal the substances which are extremely easy to permeate to the outside such as turpentine, tannin and the like acknowledged in the wooden ware industry, and solves common problems for wide application of the aqueous wooden ware paint. The aqueous sealing paint also can be used for a solvent type paint coating system, and effectively prevents a large amount of solvent in the solvent type paint from penetrating into the wood during coating.
