Abstract

The invention provides waterborne single-component sealing primer and a production technology thereof. The waterborne single-component sealing primer is prepared from the following raw materials in percentage by weight: 70 to 90 percent of waterborne acrylic resin, 2 to 10 percent of a film-forming auxiliary agent, 0.1 to 1 percent of a wetting auxiliary agent, 0.1 to 1 percent of a leveling auxiliary agent, 0.1 to 1 percent of a de-foaming auxiliary agent, 5 to 20 percent of silica sol and 2 to 3 percent of waterborne color paste; the waterborne single-component sealing primer has waterborne,environment-friendly, water-resisting, alkali-resisting properties and the like and also has the advantages of bacterium prevention, mildew prevention and the like; the service life of the primer iseffectively prolonged; and a preparation process is simple and practical and the production efficiency is high.

Description

technical field [0001] The invention relates to a wood varnish, in particular to a water-based one-component sealing primer and a production process thereof. Background technique [0002] At present, countries all over the world have higher and higher requirements on the environment, especially in some developed countries, the content of volatile organic compounds (VOC) in coatings has been restricted, and the emission of volatile organic compounds has also been restricted. Therefore, solvent-free coatings are more and more popular among consumers because of their advantages of reducing air pollution caused by organic solvent volatilization. [0003] On January 27, 2003, the European Parliament and the Council of the European Union passed Directive 2002 / 95 / EC, namely "The Restriction of the use of Certain Hazardous Substances in Electrical and Electronic Equipment" (The Restriction of the use of Certain Hazardous Substances in Electrical and Electronic Equipment) Equipment)...
