Embodiment Construction

[0038] Step 4: Extrude the masterbatch obtained in the above steps to blow the film, the blown film temperature is controlled at 180°C, and the anti-aging polyester film is obtained after further stretching.

[0039] The above samples were tested to obtain

[0040] The detection device includes a light source, a heat source, a camera, and a processor.

[0041] The light source is used to irradiate the anti-aging film, thereby causing the photo-instability of the anti-aging film, thereby causing discoloration.

[0042] The heat source is used to apply heat to the anti-aging film, thereby causing thermal instability of the anti-aging film, and thus discoloration.

[0043] The camera is used to take the image of the anti-aging film before discoloration and the image after discoloration after a period of time.

[0044] The processor is used to control the opening and closing of the light source and the camera, and is used to record time stamps when the camera takes pictures. In...

Abstract

The invention relates to a preparation method of an anti-aging polyester film material. The preparation method comprises the following steps: preparing 0.1%-0.2% of W944, 0.1%-0.2% of UV329, 0.1%-0.2% of UV531, 0.4%-0.5% of zinc stearate, 0.4%-0.5% of zeolite, 0.05% of TiO2 and polyester; carrying out extrusion, film blowing and further stretching on the master batch to obtain an anti-aging polyester film; placing the polyester film in an aging environment with an ultraviolet light source, an infrared light source and a heat source for aging, acquiring an image of the polyester film, and sending the image into the neural network model for judging the anti-aging performance of the film and the consistency of the anti-aging performance; and optimizing the components, the proportion and the preparation process of the anti-aging polyester material master batch according to the judgment result. Therefore, the preparation process of the anti-aging polyester material can be optimized, and the polyester material with better light stability and heat stability is obtained.

Description

technical field [0001] The content of the present invention belongs to the field of polymer film materials, in particular, it relates to a preparation method of an anti-aging film material. Background technique [0002] In actual use, polyester film will be affected by temperature and light to cause aging. The principle is that light and temperature cause changes inside the polyester material. After the film is aged, its optical and mechanical properties will change greatly, for example, the color will turn yellow, the film will become brittle or cracked, etc., which will bring inconvenience to use. [0003] For this reason, how to improve the anti-aging performance of polyester film is a problem that needs to be solved in the process of polyester material research and development. In the prior art, the light stability and heat stability of the polyester film are improved by adding light stabilizers and heat stabilizers. However, the existing design ideas are to consider l...
