Highly weather-resistant waterborne mildewproof varnish for wooden ware

Abstract

The invention relates to a highly weather-resistant waterborne mildewproof varnish for wooden ware. The highly weather-resistant waterborne mildewproof varnish is prepared from the following raw materials in percentage by weight according to a proportional ratio: 65 to 80% of waterborne acrylic emulsion, 0.2 to 0.5% of defoamer, 0.2 to 0.5% of wetting agent, 0.1 to 0.2% of ammonia neutralizing agent, 0.2 to 0.5% of flatting agent, 2 to 5% of film-forming additive, 2 to 15% of deionized water, 0.05 to 0.1% of tank internal sterilizant, 0.1 to 0.5% of ultraviolet light absorbent, 0.1 to 0.5% oflight stabilizer, 0.5 to 1.5% of dry film mildewproof agent, and 0.1 to 2% of thickener. The highly weather-resistant waterborne mildewproof varnish has the advantages that the deionized water is usedfor blending the film-forming additive, the internal sterilizant and the dry film mildew-proof agent, the filming property is good, a paint film is dense, flexible and tough, the high temperature-resistant property and water-resistant property are good, the easiness in whitening is avoided, the chemical stability is excellent, and the easiness in cracking due to temperature differences between daytime and night and weather change is avoided; the environment-friendly effect is realized, the content of VOC (volatile organic compound) is low, the heavy metal is not contained, the sunlight radiation-resistant property is realized, the easiness in yellowing, delaminating and aging is avoided, the mildew-proof property is strong, and the outdoor common mildews and bacteria with function on woodcan be resisted.

Description

technical field [0001] The present invention relates to the application technology of IPC classification C09D paint composition raw material for this purpose, especially the highly weather-resistant water-based mildew-proof varnish for woodware. Background technique [0002] Water-based paint is a paint that uses water as a diluent. Water-based paints include water-soluble paints, water-diluted paints, water-dispersible paints or latex paints. Water-soluble paints use water-soluble resins as film-forming materials, represented by polyvinyl alcohol and its various modified products, in addition to water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. [0003] At present, water-based wood paints have achieved good results in indoor furniture, but for some outdoor wood products such as outdoor floors, park seats, gazebos, plant landscape fences, etc., there are still many shortcomings in water-based paints. The two main aspects are ...
