Tea polyphenol / tpe composite nylon encapsulating material
By adding ammonolytic modified diester oil and tea polyphenols to TPE materials, an intermolecular force physical cross-linking network is formed with the nylon substrate, solving the problems of poor stability and small molecule migration of TPE materials, and achieving good adhesion and biocompatibility.

Abstract
The application provides a tea polyphenol / TPE composite nylon encapsulating material, which comprises the following components in parts by weight: SEBS: 100 parts; PP: 100 parts; amino-lysis modified double-ester oil: 100-300 parts; tea polyphenol: 10-30 parts; high-temperature-resistant antioxidant: 0.5-1.0 parts. The application uses the bio-based material tea polyphenol as a polarity improver and an adhesion promoter, so that the TPE material can form a good adhesive layer with the nylon in double-color injection molding without other adhesion promoters; meanwhile, the strong hydrogen bond formed between the tea polyphenol and the amino-lysis modified double-ester oil can firmly lock the tea polyphenol, so that the TPE material will not have small molecule migration during use, and the tea polyphenol as a green bio-based material has a small odor and low emission, which can greatly improve the odor and biological safety of the TPE material.
