Talcum powder-guaifenesin water-based polyurethane anticorrosive paint for rattan crafts and preparation method thereof

Abstract

The invention discloses talcum powder-guaifenesin water-based polyurethane anticorrosive paint for rattan crafts. The water-based polyurethane anticorrosive paint is prepared from the following raw materials in parts by weight: 0.5 to 1 part of nanometer talcum powder, 0.5 to 1 part of guaifenesin, 0.1 to 0.15 part of cetyl pyridinium chloride, 10 to 15 parts of nanocellulose suspension with 10 to 12% of solid content, 0.3 to 0.5 part of guar gum, 40 to 50 parts of water-based polyurethane resin, 0.5 to 1 part of octenyl succinic anhydride, 4 to 6 parts of absolute ethyl alcohol, 0.3 to 0.5 part of potassium sorbate, 0.5 to 1 part of kathon preservative, and 0.3 to 0.5 part of water-soluble lanolin. The water-based polyurethane anticorrosive paint has the advantages that the anti-bacterial and anticorrosive properties are good, the toughness is high, the binding property with rattan fiber is good, the easiness in cracking and falling is avoided, the paint film is fine and smooth, the color is uniform, the appearance quality is high, and the sanitation and decoration properties are good.

Description

technical field [0001] The invention relates to the technical field of water-based paints, in particular to a talcum powder-guaiacol glycerin ether rattan handicraft water-based polyurethane anticorrosive paint 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 ratta...

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
