Water-based technical wood yellow-resistant matte varnish and preparation method thereof

The invention discloses a water-based technical wood yellow-resistant matte varnish and a preparation method thereof. The water-based technical wood yellow-resistant matte varnish comprises the following preparation raw materials by weight: 40.0-80.0% of special water-based resin; 0.0% to 40.0% of water-based resin; 6.0%-8.0% of a film forming agent; 0.4%-0.6% of a water-based defoaming agent; 0.2%-0.4% of a water-based wetting agent; 0.2%-0.4% of a water-based leveling agent; 0.0%-1.5% of water-based matting powder; 2.0%-3.0% of water-based wax slurry; 0.1%-0.2% of a water-based bactericide; 1.0%-2.0% of a water-based anti-settling auxiliary agent; 1.5%-2.5% of a water-based anti-yellowing auxiliary agent; 0.5%-1.6% of a water-based thickening agent; and the balance of deionized water. The water-based anti-yellowing auxiliary agent is a benzotriazole mixture. The prepared water-based technical wood yellowing-resistant matte top-coat has the advantages of being environmentally friendly, good in hand feeling,
