Abstract

The invention discloses a waterproof antibacterial polyurethane adhesive, which is prepared from the following raw materials in parts by weight: 100 parts of polyurethane prepolymer, 0.1-1.5 parts ofnano-silver, 5-12 parts of modified filler, 3-12 parts of hexadecyltrimethoxysilane modified nano-zinc oxide, 1-3.5 parts of dihydromethyl propionic acid, 2-7 parts of 1,6-hexanediamine, 0.3-1.5 partsof triethylamine, 0.1-1 part of dibutyltin dilaurate, 1-3.5 parts of plasticizer, 0.2-1.3 parts of polrvinyl benzene, 5-20 parts of glycol dimethyl ether, 0.3-1.2 parts of 2,4,4-trichlorine-2-hydroxy-diphenyl ether and 2-5 parts of dodecafluoroheptyl methacrylate, wherein the polyurethane prepolymer is obtained in a way that diferrocenyl alcohol, hydroxyl-terminated polybutadiene, polyester polyol, triphenylmethane triisocyanate and p-phenylene diisocyanate react. The waterproof antibiosis polyurethane adhesive which is put forward by the invention has the advantages of high binding strength,good antibacterial property and excellent water-proof performance.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a waterproof and antibacterial polyurethane adhesive. Background technique [0002] Adhesives are natural or synthetic, organic or inorganic substances that can connect two or more parts or materials together through interface adhesion and cohesion. Polyurethane has the advantages of high elasticity, wear resistance, low temperature resistance, solvent resistance, and good electrical insulation. The polyurethane adhesive made of it has the advantages of good adjustability, low temperature resistance, and good flexibility. At present, It has been used in railway, book binding, construction, ink, packaging, wood, automobile and other fields. However, the current polyurethane adhesives have the disadvantages of low bond strength, poor antibacterial and water resistance, which limit their application range. Contents of the invention [0003] Based on the technical problems in t...
