Problems solved by technology

The traditional production process of TPU film is mainly casting. This process has low production capacity and uneven film thickness. All functional modification additives need to be granulated first and then added, which makes the production cost extremely high and the plasticization is uneven, which limits TPU. Promotion and Application of Thin Film

Abstract

The invention discloses a modified TPU thin film. The modified TPU thin film takes TPU particles as the raw materials and comprises compatilizer, filler, flame retardants, natural polyphenols, epoxy resin and a light stabilizer, and the modified TPU thin film comprises, by weight, 70-80 parts of the TPU particles, 3-6 parts of the compatilizer, 1-3 parts of the filler, 2-4 parts of the flame retardant, 5-8 parts of the natural polyphenols, 10-20 parts of the epoxy resin and 0.5-1.5 parts of the light stabilizer. The modified TPU thin film has the advantages of being high in yield, even in thickness, high in surface gloss and has the hydrolysising property simultaneously, and the added natural polyphenols can effectively enhance yellowing resistance of the film; by means of the addition of the other components, the performance of the film is more stable, and the modified TPU thin film is suitable for application and promotion.

Description

technical field [0001] The invention relates to a film, in particular to a modified TPU film. Background technique [0002] Thermoplastic elastomers are more and more widely used due to their excellent elongation at break, resilience, wear resistance, weather resistance and superior processing and molding methods compared to cast polyurethane. In particular, due to the rapid development of the polyurethane industry, the production capacity of raw material manufacturers has been continuously expanded, and the cost has been continuously reduced, thereby promoting the application and development of new rounds of polyurethane products. TPU film has the characteristics of good toughness, high strength, odorless, non-toxic, and can be heat-sealed. It is widely used in the fields of automobile industry, medical and health care, and daily necessities. The traditional production process of TPU film is mainly casting. This process has low production capacity and uneven film thickness...
