Dirt-resistant cane handicraft waterborne polyurethane anti-corrosion paint and preparing method thereof

Abstract

The invention discloses a dirt-resistant cane handicraft waterborne polyurethane anti-corrosion paint. The paint is prepared from, by weight, 40-50 parts of waterborne polyurethane resin, 0.1-0.15 part of polysorbate 80, 10-15 parts of nano-crystalline cellulose suspension with 10-12% solid content, 0.3-0.5 part of guar gum, 0.5-1 part of octenyl succinic anhydride, 0.5-1 part of texanol, 4-6 parts of ethanol, 0.5-1 part of casson preservative, 0.3-0.5 part of 13 (n-ethylperfluorooctanesulfonamido triethoxy silane and 0.05-0.1 part of chloririated paraffin-52. The waterborne polyurethane anti-corrosion paint has good anti-corrosion property, high toughness, good combination properties with rattan cane fiber and is not easy to crack and come off. Moreover, the waterborne polyurethane anti-corrosion paint has good waterproof, stain-resistance properties and is easy to clean.

Description

technical field [0001] The invention relates to the technical field of water-based paints, in particular to a water-based polyurethane anti-corrosion paint for anti-contamination 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 surface is ...

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
