Abstract

The invention belongs to the field of polyurethane surface treatment agents, and particularly relates to a self-extinction skin-feeling solvent-free polyurethane waterborne matte surface treatment agent. The self-extinction skin-feeling solvent-free polyurethane waterborne matte surface treatment agent comprises 100 parts of waterborne extinction polyurethane resin, 150 parts of water, 4 parts ofwetting agent UL-5125, 0.5 part of defoaming agent F-530, and 5 parts of polyurethane thickening agent 8807. The invention further provides a preparation method. By adopting the self-extinction skin-feeling solvent-free polyurethane waterborne matte surface treatment agent, the problem of surface whitening of synthetic leather due to the separation of an organic phase and an inorganic phase of silicon dioxide and polyurethane film-forming agent in the existing treatment agent can be solved; and by jointly using the wetting agent and the defoaming agent, not only can the surface energy be reduced, but also bubbles of the film can be reduced, and the adhesiveness of the surface treatment agent can be improved.

Description

technical field [0001] The invention belongs to the field of polyurethane surface treatment agents, in particular to a solvent-free polyurethane water-based matte surface treatment agent with self-extinction skin feeling. Background technique [0002] Synthetic leather is a kind of polyurethane soft product. The traditional synthetic leather surface treatment agent is generally prepared by solvent polyurethane. Its use has brought huge damage to the environment. Water-based polyurethane surface treatment agent can solve the pollution of synthetic leather surface treatment agent very well. question. Matting treatment is one of the most common surface effects in the surface treatment of synthetic leather. It can endow synthetic leather with soft natural luster and good touch, and is widely loved by the market. The traditional matting treatment of synthetic leather uses inorganic silica as matting particles. After compounding with polyurethane film-forming agent, it has a good...
