Problems solved by technology

[0006] The matting powder used in the above-mentioned patents is silicon dioxide, and the wear-resisting additives are various wax emulsions, glass powder and polyether modified siloxane polymers. The film of matte paint has poor brittleness, which can easily cause the performance of the coating to decline, such as precipitation affecting storage stability, poor polishing resistance of the coating, and decreased transparency of the coating film.

Abstract

The invention relates to a preparation method of a water-based two-component high-temperature-resistant ultra-wear-resistant matte varnish. Hydroxyl-containing water-based resin, SMA resin, PMMA microspheres, additives and water; component B is a water-based polyurethane curing agent; the water-based two-component high-temperature resistant super wear-resistant matte varnish prepared by the present invention has a paint film with Excellent high temperature resistance, super abrasion resistance, water resistance, weather resistance and chemical stability, improve the texture and fullness of the paint film surface, good flexibility and smooth handle, excellent matting effect without affecting Transparency and vividness of the paint film; low VOC, no heavy metals, environmental protection; widely used in the surface coating and protection of substrates that require high temperature resistance, high wear resistance and scratch resistance, and matte effect, such as water-based floor paint , Water-based high-grade wood paint, water-based plastic paint, water-based mobile phone paint and water-based industrial paint.

Description

technical field [0001] The invention relates to a preparation method of a water-based two-component matte varnish, in particular to a water-based two-component high-temperature-resistant ultra-wear-resistant matte varnish, which belongs to the technical field of water-based paints. Background technique [0002] With the improvement of people's living standards and high attention to health, the future home decoration and furniture coating market must be dominated by water-based paint. According to statistics, the output of wood coatings in my country was about 800,000 tons in 2008. In 2010, the total output of wood coatings in China was 1.06 million tons, of which polyurethane coatings accounted for the highest proportion, about 70%, of which water-based wood coatings only accounted for about 10%. However, compared with oil-based paint, water-based wood paint has the disadvantages of low hardness, fullness, gloss, temperature resistance, water resistance, wear resistance and ...
