Abstract

The invention relates to a quick-drying waterproof type polyurethane adhesive. The quick-drying waterproof type polyurethane adhesive is prepared from, by weight, 30-40 parts of isophorone diisocyanate, 10-15 parts of triethylamine, 20-25 parts of polyether polyol, 1-4 parts of polyoxypropylene glycerol ether, 2-5 parts of phenyl salicytate, 5-7 parts of epoxy biacrylate, 1-2 parts of 2-heptanone, 10-15 parts of thickening agent, and 6-9 parts of chain extender. The quick-drying waterproof type polyurethane adhesive is simple in formula and high in stability, and not only suitable for dark and wet environment but also to the outdoor with strong ultraviolet ray.

Description

technical field [0001] The invention relates to an adhesive, in particular to a quick-drying waterproof polyurethane adhesive. Background technique [0002] Polyurethane adhesive refers to the adhesive containing carbamate group (-NHCOO-) or isocyanate group (-NCO) in the molecular chain, because it contains isocyanate and carbamate with strong polarity and high chemical activity. Ester groups, so it has excellent chemical adhesion to materials containing active hydrogen, such as porous materials such as foam plastics, wood, leather, fabrics, paper, ceramics, and materials with smooth surfaces such as metals, glass, rubber, and plastics. work together. Polyurethane adhesives also have good toughness, adjustability, simple bonding process, excellent low temperature resistance and excellent stability. It is precisely because of the excellent bonding performance of polyurethane adhesives and the bonding adaptability to various substrates that its application fields continue t...
