Abstract

The invention provides a medical heat-sensitive film and a preparation method thereof. The film comprises a polyester substrate, an antistatic layer is provided on one side of the polyester substrate, and an imaging layer and a protective layer are sequentially provided on the other side. The invention well solves the problems of cumbersome production and high cost of the existing heat-sensitive film, and the production method of the heat-sensitive film of the invention is simple and easy, significantly improves production efficiency, and greatly reduces production cost.

Description

technical field [0001] The invention relates to the field of medical films, in particular to a medical heat-sensitive film and a preparation method thereof. Background technique [0002] With the continuous upgrading of the manufacturing technology of digital medical imaging inspection equipment and the widespread application in medical institutions at all levels, the use of printing media for medical images is increasing day by day, and the application of medical thermal film has achieved unprecedented development. However, the existing The thermal film production is loaded down with trivial details, and cost is higher, urgently needs research and solution. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a medical thermosensitive film and its preparation method, which are used to solve the problems of cumbersome production and high cost of the thermosensitive film in the pri...
