Problems solved by technology

[0003] However, the absorption rate of ultraviolet rays is low. Since the wavelength of ultraviolet rays is smaller than the particle size of polymers, part of the ultraviolet rays will be reflected and lost when encountering polymers.

Description

technical field [0001] The invention belongs to the field of preparation of textile engineering adhesives, in particular to a UV photocurable water-based polyurethane adhesive. Background technique [0002] Polyurethane (PU) adhesive refers to the adhesive containing carbamate group (-NHCOO-) or isocyanate group (-NCO) in the molecular chain, which can be divided into two categories: polyisocyanate and polyurethane. Since the polyurethane adhesive contains these two groups and shows high activity and polarity, it is applied to many substrates, such as foam, plastic, wood, leather, fabric, paper, ceramics and other porous materials, as well as metal, glass, etc. , rubber, plastic and other materials with smooth surface, it has excellent adhesion to them. However, at present, polyurethane adhesives are still mainly solvent-based. Due to the shortcomings of organic solvents such as flammability, explosion, volatility, and strong odor, they are likely to cause environmental po...
