Problems solved by technology

[0003] However, there are many particles in the TPU film processed by the traditional formula, and the sticky feeling is very strong when touched by hand.
In addition, the stability in the heat treatment process in the proportion is poor, and the water resistance and shrinkage are poor, resulting in a decrease in the tensile strength of the finished TPU film

Abstract

The invention relates to thin film, in particular to improved TUP thin film. According to the technical scheme, the film is prepared from, by mass, 15-25 parts of diphenylmethane diisocyanate, 40-55 parts of adhesive, 3-5 parts of dihydric alcohol, 1-3 parts of polybutylene terephthalate, 1-3 parts of ion exchange resin, 1-2 parts of cross-linking agent and 1 part of stabilizer. By adopting the technical scheme, the improved TUP thin film is good in contractility and stable in extension strength, and a user has no gooey feeling when touching the improved TUP thin film.

Description

technical field [0001] The invention relates to a film, in particular to an improved TUP film. Background technique [0002] TPU film is a kind of thermoplastic elastomer. In fact, on the basis of TPU pellets, it is made into film by calendering, casting, film blowing, coating and other processes, and it is widely used in sports shoes. It has the advantages of five poisons and degradability. [0003] However, there are many particles in the TPU film processed by the traditional formula, and it feels very sticky when touched by hand. And in the proportioning, the stability during the heat treatment process is poor, and the water resistance and shrinkage are poor, resulting in a reduction in the tensile strength of the finished TPU film. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the invention provides an improved TUP film with good shrinkage, stable tensile strength and no sticky feeling when touched. [0005] In order to achieve the ...
