Halloysite nano-tube composite rattan handicraft product aqueous polyurethane anticorrosive paint and preparation method thereof

Abstract

The invention discloses a halloysite nano-tube composite rattan handicraft product aqueous polyurethane anticorrosive paint, which is prepared from the following raw materials by weight: 0.5-1 part of halloysite nano-tubes, 0.3-0.5 part of sodium diethylhexyl sulfosuccinate, 10-15 parts of nanocellulose suspension with a solid content of 10-12%, 0.3-0.5 part of guar gum, 40-50 parts of an aqueous polyurethane resin, 0.5-1 part of octenylsuccinic anhydride, 4-6 parts of anhydrous ethanol, 0.5-1 part of a kathon anticorrosive agent, 2-4 parts of a bamboo vinegar liquid, 0.3-0.5 part of eucalyptus leaf oil, and 0.1-0.15 part of tea polyphenol. According to the present invention, the aqueous polyurethane anticorrosive paint has advantages of good corrosion resistance, high toughness, good binding property with rattan fiber, cracking resistance, shedding resistance, antibacterial effect, air purifying effect, green and environmental protection, safety, and health.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a halloysite nanotube composite 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 rattan surface...

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
