Abstract

The invention discloses an antibacterial waterproof polyurethane coating and a preparation method thereof. The antibacterial waterproof polyurethane coating is prepared from the following raw materials in parts by weight: 150-180 parts of polyester polyol, 15-20 parts of 1,6-hexamethylene diisocyanate, 25-30 parts of isophorone diisocyanate, 10-14 parts of 2,2-dimethylolpropionic acid, 20-25 parts of triethylamine, 10-12 parts of nanometer silver, 7-9 parts of citrate, 10-12 parts of kaolin, 7-9 parts of propylene glycol, 5-7 parts of neopentyl glycol diacrylate, 3-5 parts of organic bismuth, 7-9 parts of dibutyltin dilaurate, 3-4 parts of diethanolamine diacetone acrylamide amide, 6-7 parts of polydimethoxy siloxane, 8-9 parts of nanometer titanium dioxide, 12-14 parts of dodecyl polyoxyethylene ether, 18-20 parts of acetone, 0.6-0.8 part of sodium dodecyl sulfate, 40-50 parts of triethylene sulfophosphamide and 9-10 parts of an additive. By selecting the propylene glycol as a chain extender and by the cooperation of a fluorine type flattening agent, the antibacterial waterproof polyurethane coating disclosed by the invention is improved in waterproof effect; by adding the nanometer silver and benzoin, the coating has antibacterial and sterilization effects.

Description

technical field [0001] The invention relates to the field of chemical products, in particular to an antibacterial and waterproof polyurethane coating and a preparation method thereof. Background technique [0002] Polyurethane coatings are currently the most common type of coatings, which can be divided into two-component polyurethane coatings and one-component polyurethane coatings. Two-component polyurethane coatings are generally composed of isocyanate prepolymers and hydroxyl resins, commonly known as curing agent components and main agent components. There are many varieties of this type of coating, and the application range is also very wide. According to the difference of the hydroxyl group-containing components, it can be divided into acrylic polyurethane, alkyd polyurethane, polyester polyurethane, polyether polyurethane, epoxy polyurethane and other varieties. Generally, they have good mechanical properties, high solid content, and good performance in all aspects....
