Problems solved by technology

This invention uses aromatic polycarbonate to modify the polyurethane elastomer to increase its color fastness, but its color is not bright enough, and it also has a certain dependence on the external temperature. With the extension of use time, the material is easy to turn yellow , the color is difficult to keep bright, affecting the appearance
[0004] CN110256834A discloses a TPU ultra-thin color waterproof and moisture-permeable film. The components of the film and the parts by weight of each component are: 50-100 parts of TPU particles, 10-20 parts of color masterbatch and 5-10 parts of light calcium dispersant ; wherein the components of the color masterbatch and the weight fraction of each component are: 10-40 parts of pigment, 60-80 parts of TPU carrier, and 0.1-1 part of diffusing agent NNO. When TPU color masterbatch is used to color TPU, due to The fluidity of the color masterbatch is poor, and the molding processing type is likely to cause poor dispersion uniformity of the color masterbatch in TPU, and it is prone to color instability, easy to fade and difficult to control the color difference.

Abstract

The invention provides an environment-friendly colored TPU film for furniture and a preparation method of the environment-friendly colored TPU film. The environment-friendly colored TPU film for furniture is prepared from the following raw materials in parts by weight: 55-75 parts of polyether polyol, 25-35 parts of diisocyanate, 1-10 parts of a chain extender, 10-20 parts of modified polytetrafluoroethylene, 1-10 parts of modified basalt fibers, 1-5 parts of a nano photocatalyst, 1-5 parts of a plant pigment, 0.5-3 part of an epoxy group-containing silane coupling agent and 0.05-0.1 part of acatalyst. The environment-friendly colored TPU film for furniture is uniform in component color dispersion, free of color stripes and free of local color difference, has excellent waterproof performance and various mechanical properties, is green and environment-friendly in component raw materials, and is suitable for the field of furniture protection.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a TPU film and a preparation method thereof, in particular to an environment-friendly colored TPU film for furniture and a preparation method thereof. Background technique [0002] TPU (Thermoplasticpolyyrethane, thermoplastic polyurethane) is a new type of organic polymer synthetic material with excellent properties; for example, the wear resistance and resilience are better than ordinary polyurethane and PVC, and the aging resistance is better than rubber. It is a substitute for PVC and PU. The ideal material is an internationally recognized new polymer material. In the coloring of TPU materials, the main use now is to directly add pigment products or dye products into polyurethane resin for synthetic leather, and after stirring, fully mix the pigment products or dye products with polyurethane resin to achieve the purpose of polyurethane resin coloring.
