Abstract

The invention discloses a composite flexible transparent film material. The composite flexible transparent film material is composed of the following components according to the weight ratio: 15-17 parts of polyurethane, 8-12 parts of polycarbonate, polymethacrylic acid 4-9 parts of butyl ester, 3-4 parts of succinic anhydride, 6-8 parts of dimethylacetamide, and 8-13 parts of propyl acetate. The preparation method includes heating, mixing, coating, cooling and separation of raw materials to prepare a composite flexible transparent film material. The prepared composite flexible transparent film material has higher light transmittance and better heat resistance characteristics.

Description

technical field [0001] The invention belongs to the field of film materials, and relates to a transparent film material and a preparation method thereof, in particular to a composite flexible transparent film material and a preparation method thereof. Background technique [0002] In the field of solar energy, flexible film materials have many uses due to their outstanding characteristics. In addition to the field of solar energy, in some fields that need to use thin films, there are high requirements for the physical properties of flexible transparent film materials. Such as the light transmittance of the flexible transparent film material, as well as its heat resistance. [0003] In electronic products, many products such as mobile phones and televisions also need to use flexible film materials. These flexible film materials must have very high light transmittance. In addition, because electronic products will have high temperature in a certain environment, their transpa...
