Waterborne polyurethane anticorrosive paint for moisture-proof and mothproof rattan craftwork and preparation method thereof

Abstract

The invention discloses a waterborne polyurethane anticorrosive paint for a moisture-proof and mothproof rattan craftwork. The waterborne polyurethane anticorrosive paint is prepared by the following raw materials in parts by weight: 1-1.5 parts of nano silica hollow spheres, 0.3-0.5 part of camphor oil, 0.1-0.2 part of sandalwood oil, 10-15 parts of a nano cellulose suspension with a solid content of 10-12 percent, 0.3-0.5 part of guar gum, 40-50 parts of waterborne polyurethane resin, 0.5-1 part of octenyl succinic anhydride, 4-6 parts of anhydrous ethanol, 0.05-0.1 part of polyoxypropylene glycerol ether, 0.5-1 part of a Kathon preservative, 1-2 parts of rosin emulsion and 0.5-1 part of calcium sulfate whiskers. The waterborne polyurethane anticorrosive paint disclosed by the invention is good in corrosion resistance, high in toughness, good in binding property with rattan fibers and difficult to crack and fall off and simultaneously has good moisture-proof and mothproof properties and good durability.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a water-based polyurethane anti-corrosion paint for moisture-proof and insect-proof 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
