Waterborne polyurethane antiseptic paint for yellowing-and-ageing resistant vine artware and preparation method of waterborne polyurethane antiseptic paint

Abstract

The invention discloses waterborne polyurethane antiseptic paint for yellowing-and-ageing resistant vine artware. The waterborne polyurethane antiseptic paint comprises, by weight, 10-15 parts of nano-cellulose suspensions with the solid content of 10-12%, 0.5-1 part of nano zinc oxide, 0.3-0.5 part of guar gum, 0.5-1 part of hydroxyl silicone oil, 40-50 parts of waterborne polyurethane resin, 0.1-0.15 part of nonylphenol polyoxyethylene ether, 0.5-1 part of octenyl succinic anhydride, 4-6 parts of absolute ethyl alcohol, 0.05-0.1 part of benzotriazole, 0.5-1 part of Kathon aseptic and 0.3-0.5 part of sodium salicylate. The waterborne polyurethane antiseptic paint has the advantages of good antiseptic performance, high tenacity, good combination performance with vine fibers, less proneness to cracking and shedding, high ultraviolet and ageing resistance, less proneness to yellowing and high appearance quality.

Description

technical field [0001] The invention relates to the technical field of water-based paints, in particular to an anti-yellowing and anti-aging water-based polyurethane anti-corrosion paint for rattan handicrafts and a preparation method thereof. Background technique [0002] Rattan is a natural healthy and environmentally friendly material. It is strong, light and flexible, and can be bent at will. The rattan handicrafts made of it have a simple and clear appearance, coexistence of rigidity and softness, and are popular among people. of favor. The cross-section of rattan is covered with fine ducts, so rattan handicrafts are easy to absorb water, and once too much water is absorbed, the handicrafts will become soft and drooping, loose in structure, and prone to mildew and decay. Thereby having had a strong impact on the performance of rattan crafts. In order to reduce the impact of rattan decay on the quality and life of rattan handicrafts, painting a paint film on the rattan...

Problems solved by technology

CN201310576524 has improved the coating performance of water-based paint on soft materials such as rattan and wood products by utilizing the ratio adjustment of water-based polyurethane resin and water-based acrylic resin, but the performance improvement of coating materials is limited only by the matching and adjustment of organic resin components , the toughness of the paint film formed by the obtained water-based paint on the surface of the rattan handicraft and its bonding performance with the rattan material are insufficient, and cracks are easily formed at the bent part, and then crack and fall off, which is not conducive to maintaining the paint film on the surface of the rattan handicraft. Durability, thus affecting its anti-corrosion protection effect on rattan crafts
