Problems solved by technology

The heat transfer film currently produced on the market is prone to adhesion between the films due to the added release agent, and cannot be reused
Many outdoor advertising posters are made of thermal transfer film, and these thermal transfer films have no UV protection function, so long-term exposure to sunlight without protective measures causes the posters to be overexposed and faded, etc.

Abstract

The invention discloses an anti-ultraviolet polyethylene terephthalate (PET) heat transfer film. The anti-ultraviolet PET heat transfer film is mainly prepared from the following raw materials in parts by weight: 80 to 90 parts of PET polyester slice, 15 to 20 parts of nanometer titanium dioxide PET master batch, 5 to 10 parts of RC-E60 silicon-free mold release agent and 1 to 5 parts of aid. The anti-ultraviolet PET heat transfer film disclosed by the invention has the characteristics, such as transparency and matte, of the heat transfer film, and also has an anti-ultraviolet function, so that the heat transfer film can be applied in the fields of heat transfer printing, optics, advertising graphics and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a PET thermal transfer film capable of preventing ultraviolet rays and a preparation method thereof. Background technique [0002] Thermal transfer film is a polar material that is moisture-resistant, air-tight, soft, strong, resistant to acids, alkalis, greases and solvents, and is not afraid of high and low temperatures. The heat transfer film currently produced on the market is prone to adhesion between the films due to the added release agent, and cannot be reused. Many outdoor advertising posters are made of thermal transfer film, and these thermal transfer films have no UV protection function. Therefore, long-term sunlight exposure without protective measures causes the posters to be overexposed and faded. Therefore, the demand for heat transfer films with anti-ultraviolet function is very urgent. Contents of the invention [0003] Purpose of the ...
