Abstract

The invention relates to seal primer capable of sealing organic acid and pigment of timbers and a preparation method of the seal primer capable of sealing organic acid and pigment of timbers, and belongs to the technical field of paint. The seal primer capable of sealing organic acid and pigment of timbers consists of the following raw materials in percentage by mass of aqueous emulsion including80%-85% of aqueous polyurethane emulsion, addition agents including 5%-7% of film formation addition agents, 0.4-0.8% of an antifoaming agent, 0.1-0.2% of flatting agents, 0.2%-0.3% of base material wetting agents, 1.2-2.2% of tannic acid resistant addition agents, 8-9% of deionized water and 0.1-0.5% of thickening agents. The seal primer capable of sealing organic acid and pigment of timbers andthe preparation method of the seal primer capable of sealing organic acid and pigment of timbers disclosed by the invention have the characteristics of being excellent in brightness, smoothness, colorchange resistance and corrosion resistance, high in adhesiveness and the like, and particularly, the seal primer capable of sealing organic acid and pigment of timbers has favorable properties of sealing the organic acid and the pigment.

Description

technical field [0001] The invention relates to a sealing primer capable of sealing wood organic acids and pigments and a preparation method thereof, belonging to the technical field of rapid prototyping. Background technique [0002] We will use a lot of wood in the decoration process, and in the process of wood treatment, before painting, it must be treated with a special board sealer, which can effectively protect the board. The board sealant is applied on the surface of the board before painting, which can form a layer of protective film. The main functions of the board sealer are sealing barrier, anti-fouling, anti-deformation and cracking, etc., so as to ensure that the decoration users can finally get Perfect film effect, perfect substitute for nitro varnish. However, the plate sealers in the prior art are generally solvent-based coatings, which have the characteristics of poor environmental performance, while the water-based sealers in the prior art have the disadva...
