AI Technical Summary

Technical Problem

The poor compatibility and dispersion of traditional fluorescent molecules in polyurethane materials leads to low fluorescent quantum yield and poor weather resistance and physical properties in practical applications.

Method used

The POSS-modified peryleneimide monomer is used to graft the cage-type polysilsesquioxane group at the amino terminus of peryleneimide and modify the triethylene glycol group at the bay position to improve the solubility and fluorescent quantum yield of molecules. At the same time, the combination of oligomer polyols and isocyanate is embedded into the aqueous polyurethane molecular chain to improve the weather resistance and physical and mechanical properties of the material.

Benefits of technology

The solid-state fluorescent quantum yield and physical and mechanical properties have been significantly improved, and the development of efficient and environmentally friendly fluorescent polyurethane materials has been achieved.

Abstract

The invention provides wear-resistant fluorescent waterborne polyurethane and a preparation method thereof, and relates to the technical field of novel fluorescent polymer materials. The wear-resistant fluorescent waterborne polyurethane is prepared from the following raw materials in parts by weight: 5 to 15 parts of perylene bisimide modified monomer, 20 to 45 parts of oligomer polyol, 35 to 45 parts of isocyanate, 2 to 7 parts of hydrophilic monomer, 5 to 10 parts of chain extender, 2 to 5 parts of neutralizer and 0.01 to 0.1 part of catalyst, wherein the perylene bisimide modified monomer takes perylene bisimide as a center, the nitrogen end of the perylene bisimide is grafted with a cage type polysilsesquioxane group, and the bay position of the perylene bisimide is modified with a triethylene glycol group. The wear-resistant fluorescent waterborne polyurethane disclosed by the invention has high solid-state fluorescent quantum yield and excellent physical and mechanical properties.
