Description

Technical Field

[0001] The invention relates to the field of polymer technology, and in particular to a hindered amine light stabilizer and a preparation method and application thereof. Background Art

[0002] Polyurethane is a polymer compound that can be prepared into polyurethane plastics, polyurethane fibers, polyurethane rubbers and elastomers. It is widely used in home furnishings, construction, daily necessities, transportation, home appliances and other fields.

[0003] The ideal polyurethane material should have good weather resistance such as aging resistance, corrosion resistance, and wear resistance. However, in reality, polyurethane often cannot have multiple excellent weather resistance characteristics. Polyurethane can be divided into two categories according to the type of dispersion medium: solvent-based polyurethane and water-based polyurethane. Solvent-based polyurethane uses organic solvents as dispersion medium, commonly used are benzene, ketones, cyclic ethers, etc. Solvent-based polyurethane contains organic solvents in the production process, causing environmental pollution and production safety hazards. Water-based polyurethane uses water as dispersion medium, and the production process is greener and more environmentally friendly than solvent-based polyurethane. It is safe and easy to control. It has become a hot spot in polyurethane research. A large number of products have gradually replaced solvent-based polyurethane and applied in various fields.

[0004] However, waterborne polyurethane still has disadvantages such as poor water and solvent resistance, insufficient thermal stability, and poor mechanical properties, which limit its scope of use. Therefore, it is generally modified by adding a variety of synthetic substances during the preparation process.

[0005] At present, there are too many types of additives in the preparation process of polyurethane, which has problems such as poor overall performance, complex modification, and high preparation cost. Therefore, there is still a need to develop a multifunctional additive to improve the comprehensive performance of polyurethane. Summary of the invention
