preparation example Construction

[0023] figure 1 It is a schematic flow chart of a method for preparing a medical film according to a preferred embodiment of the present invention. Such as figure 1 As shown, the medical film preparation method of the preferred embodiment of the present invention mainly includes the following steps:

[0024] Step S100: Prepare a transparent waterproof film base.

[0025] The substrate of the medical film of the present invention is a transparent waterproof film base, preferably a PET film base. PET film base has the advantages of high temperature resistance, high transparency, low viscosity, excellent anti-static effect, long-lasting performance and stability. Since the PET film base is an anti-static base material, the continuous operation of the printer can achieve more than 1,000 sheets of paper without jamming, and the output efficiency is improved. Moreover, the PET film base is environmentally friendly, non-toxic and tasteless. It is a surface protection material tha...

Abstract

The invention provides a medical film and a preparation method thereof. The medical film comprises a substrate and an ink-absorbing coating covered on the substrate; wherein the ink-absorbing coating is composed of an ink powder absorbent, a dispersant, and an adhesive according to a weight ratio of (19-23):(1-4):(30-33), and a polyurethane prime coating is arranged between the substrate and the ink-absorbing coating. The invention also provides a preparation method of the medical film. The medical film is non-toxic and odorless, and has the advantages of cohesiveness, waterproofness, scratch resistance, and anti-static property; the drying speed of the medical film is very fast after the film absorbs ink, and the output image is clear and does not fade.

Description

technical field [0001] The invention relates to the technical field of printing film, and in particular to a medical film and a preparation method thereof. Background technique [0002] With the development of social civilization, the rapid and sustainable development of the national economy, and the continuous improvement of human medical care, the demand for medical film in the market continues to increase. Traditional silver salt CT film and X-ray medical film use silver salt photosensitive material as the medium, and cannot be exposed to light before use. Moreover, this silver salt photosensitive film can form a medical image for medical diagnosis through medical (X-ray) equipment exposure, development process, fixing process, negative image to positive image, etc., but the image can only be obtained and cannot be copied. The positive image, the image on the photo and the actual image are reversed left and right. Moreover, this silver salt photosensitive film is easily...
