Medical high-gloss waterproof digital ink-jet printed color film and preparation method

Abstract

A medical high-gloss waterproof digital ink-jet printed color film comprises a base material and a coating on the base material, wherein the base material is a high-gloss PET (polyethylene terephthalate) sheet; the coating comprises a high-gloss waterproof ink absorbing layer, an anti-static layer and an adhesive layer; and one side of the base material is coated with the high-gloss waterproof ink absorbing layer, the other side of the base material is coated with the adhesive layer firstly, and then the adhesive layer is coated with the anti-static layer. The high-gloss waterproof ink absorbing layer comprises the components in parts by mass as follows: 10%-15% of nanoscale Al2O3, 1%-2% of an adhesive, 0.1%-0.5% of a dispersing agent, 1%-5% of a color fixing agent, 0.3%-0.5% of a water-based brightening agent, 0.2%-0.4% of a surfactant, 3%-5% of a PH value conditioning agent, 70%-80% of deionized water, 0.01%-0.1% of a cross-linking agent and 0.01-0.05% of a defoaming agent. The invention further discloses a preparation method of the medical high-gloss waterproof digital ink-jet printed color film. The film has the advantages of high film manufacturing speed, zero pollution, freedom from fading, long image saving time and the like.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a medical high-gloss waterproof digital ink-jet printing color film and a preparation method thereof. Background technique [0002] Traditional silver salt photosensitive film requires a series of tedious and environmentally polluting processes such as developing, fixing, and washing in the darkroom, and the production cycle is long. The film produced is a negative film, which cannot accurately and immediately reflect pathological conditions under ordinary light. Europe and the United States adopted digital inkjet printing technology to replace traditional photosensitive film as early as a few years ago. In my country's medical industry, it has quietly emerged since 2011. Digital inkjet printers are used to directly print out the required color frontal images, replacing traditional photosensitive films. X-films and CT films are suitable for image and diagnosis of medical ...

[0002] The traditional silver salt photosensitive film requires a series of tedious and environmentally polluting processes such as developing, fixing, and washing in the darkroom, and the production cycle is long. The film produced is a negative film, which cannot accurately and immediately reflect pathological conditions under ordinary light.

Europe and the United States adopted digital inkjet printing technology to replace traditional photosensitive film as early as a few years ago. In my country's medical industry, it has quietly emerged since 2011. Digital inkjet printers are used to directly print out the required color frontal images, replacing the traditional ones. X-films and CT films are suitable for medical graphic reports and images and diagnoses of medical imaging equipment such as pathology. However, foreign digital inkjet printing films are expensive, while domestic digital inkjet printing technology is immature and has Disadvantages such as slow output speed, easy fading, and short image storage time
