Problems solved by technology

The invention has good antibacterial effect, simple manufacturing process, easy operation, low production cost, less environmental pollution, broad application prospects, and solves the problems of unstable color and difficult control of color difference caused by the poor thermal stability of existing color masterbatches.
[0006] However, the color, brightness, light transmittance and shading effect of the polyester film made of the above-mentioned color masterbatch need to be improved when the thickness is relatively thin.
In the case of relatively thin thickness, in order to achieve a better shading effect, a large amount of toner needs to be added, which will increase the production cost, and adding too much toner will affect the mechanical properties of the film

Abstract

The invention discloses a functional film as well as a preparation method and application thereof. The functional film comprises the following components in percentage by weight: 75-90% of a polyester carrier, 2-20% of inorganic toner, 0-5% of organic toner, 0.2-1% of a dispersing agent and 0.5-5% of a functional aid. The functional film provided by the invention has few crystal point defects on the surface of the film, can achieve an excellent shading effect under the condition of relatively thin thickness, does not need a printing process, is environment-friendly, also has the appearance and performance of accurate color, high brightness, opaqueness, high shading, high impact resistance and the like required by customers, has anti-ultraviolet and antibacterial functions, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of functional membranes, and relates to a functional membrane, a preparation method and application thereof. Background technique [0002] At present, most of the color films for helmets in the market adopt the structure of transparent film and printed colored coating. There are no literature reports on the color films of helmets with no printing structure, and very few manufacturers are in the process of development. The color film of the traditional printing process is highly polluted during the production process, which affects the air quality of the workshop and threatens the health of workers. The coloring is not firm, and it is easy to fall off during the later stage of blister molding. [0003] With the improvement of living standards, people pay more and more attention to their health year by year, and the national environmental protection regulations are gradually tightened. The development of print...
