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.
