Overview of waterborne polyurethane resin:
Aqueous polyurethane resin refers to polyurethane using water as a dispersion medium. In the 1990s, with the strengthening of people's awareness of environmental protection and environmental protection laws and regulations, the research and development of environmentally friendly waterborne polyurethanes have received increasing attention. The polyurethane market represents the development direction of coatings and adhesives. Surprisingly, among water-based resins, water-based polyurethane is still a representative of excellent resins, and it is one of the hotspots of modern water-based resin research.
Waterborne polyurethane applications:
Leather finishing agent
The basic use of waterborne polyurethane is as leather finishing agent. my country also has large-scale production.
Polyurethane resin is flexible and wear-resistant, and can be used as a coating agent and repair agent for natural leather and artificial leather; water-based polyurethane finishing agent overcomes the weakness of acrylic emulsion finishing agent "hot sticky and cold and brittle", and the treated leather feels soft and slippery It is cool, plump, bright, and has a strong sense of leather, which can greatly improve the quality of leather goods and enhance market competitiveness.
Early waterborne polyurethanes were linear and thermoplastic; in order to improve their strength, hardness, water resistance, and solvent resistance, trifunctional monomers could be introduced to form appropriate branches or an external crosslinking agent could be added.
Waterborne polyurethane coating
Solvent-based polyurethane coatings are a high-end paint variety, and the output has increased rapidly in the 1990s; however, conventional solvent-based polyurethane coatings contain about 40% of organic solvents, so the VOC (volatile organic compounds) of the coatings brings huge pollution to the atmosphere . One of the development directions of coatings in the 21st century is environmentally friendly coatings, that is, low-pollution or non-pollution coatings. Mainly include high-solid coatings, water-based coatings, powder coatings and radiation curing coatings. Among them, water-based paint is the most important category.
Coatings based on water-based polyurethane dispersions have developed rapidly in developed countries. Water-based polyurethane products used in substrates such as wood, metal and plastic have been continuously put on the market, and some of them have entered the Chinese market.
