With the continuous development of the polyurethane industry, more and more industries and enterprises have applied polyurethanes. Polyurethanes have a wide range of uses and can replace rubber, plastics, nylon, etc., and are used in various construction fields. Polyurethane is an emerging organic polymer material, known as the "fifth largest plastic", and it is widely used in many fields of national economy for its superior performance. Polyurethanes have waterborne polyurethanes and oily polyurethanes. What is the difference between waterborne polyurethanes and oily polyurethanes ? Today I would like to explain the difference between waterborne polyurethane and oily polyurethane, and hope to help those friends who have this need!
Waterborne polyurethane introduction
Waterborne polyurethane is a new polyurethane system that uses water as the dispersion medium instead of organic solvents. It is also called water-dispersible polyurethane, water-based polyurethane or water-based polyurethane. Waterborne polyurethane uses water as a solvent, which has no pollution, is safe and reliable, has excellent mechanical properties, good compatibility, and is easy to modify.
The water-based polyurethane resin has gradually replaced the solvent type, becoming an important direction for the development of the polyurethane industry. Waterborne polyurethane can be widely used in coatings, adhesives, fabric coating and finishing agents, leather finishing agents, paper surface treatment agents and fiber surface treatment agents.
A series of modified silicone resins were introduced into polyurethane leather, polyurethane finishing agents, polyurethane adhesives, shoe soles, polyurethane coatings, and inks. Through the comparative tests of engineers, it was found that waterborne polyurethanes and oily polyurethane products could be solved. Various problems.
The difference between waterborne polyurethane and oily polyurethane
Waterborne polyurethane chemical grouts are light yellow, while oily polyurethane sealers are dark brown. This is the most obvious difference between the two products.
The difference between water-borne polyurethane and oil-based polyurethane
The water-based polyurethane chemical grouting material has a large amount of water and a large infiltration radius, and is suitable for plugging and inrush of water in a dynamic formation, and solidification and protection of shallow and surface soil layers. Because of the good elasticity of the waterborne polyurethane chemical grouting material consolidation body, it is most suitable for impervious plugging of concrete dynamic joints.
Difference between waterborne polyurethane and oil polyurethane
Oil-based polyurethane chemical grouting material is commonly known as “cyanide condensate†in China, and its formed consolidated body has high strength and good anti-permeability, and it is suitable for projects that reinforce foundation and protect forest water. At the same time, the elasticity of oily polyurethane chemical grouting material is small, so it is more suitable for seepage prevention and reinforcement of concrete static joints.
Editor's summary: The above is a description of what is the difference between water-borne polyurethane and water-borne polyurethane and hopes to help those who have this need!
