Environmental-friendly mosquito-repellent waterborne polyurethane anti-corrosion paint for cane handicraft and preparation method thereof

Abstract

The invention discloses environmental-friendly mosquito-repellent waterborne polyurethane anti-corrosion paint for cane handicraft. The anti-corrosion paint is prepared from the following raw materials in parts by weight: 1-1.5 parts of nano-silica hollow spheres, 0.1-0.15 part of soapberry extract, 10-15 parts of nano-crystalline cellulose suspension with solid content of 10-12%, 0.3-0.5 part of guar gum, 40-50 parts of waterborne polyurethane resins, 0.5-1 part of octenyl succinic anhydride, 0.2-0.4 part of zanthoxylum oil, 0.3-0.5 part of blumea oil, 4-6 parts of absolute ethyl alcohol, 0.5-1 part of terpilenol and 0.5-1 part of a Kathon preservative. The waterborne polyurethane anti-corrosion paint disclosed by the invention is good in anticorrosive property, high in toughness, good in bonding performance with cane fibers and difficult to crack or drop and has good mosquito-repellent performance, safety and environment friendliness.

Description

technical field [0001] The invention relates to the technical field of water-based paint for handicrafts, in particular to an environmentally friendly water-based polyurethane anti-corrosion paint for mosquito-repelling 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, painti...

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
