Problems solved by technology

Unlike the traditional silver salt photosensitive film, which undergoes a series of cumbersome processes such as developing, fixing, and washing in the darkroom, it will cause environmental pollution and waste water.
Unlike dry film, it is not necessary to avoid high temperature, keep away from radiation sources and light sources, and it is expensive and easy to lose information due to secondary exposure fogging

Embodiment 1

[0010] Polyvinyl alcohol 10kg, Al 2 o 3 5%kg, sodium polyacrylate 1kg, polyethylene glycol 0.5kg, polyethyleneimine 5kg, water 73.5kg

Embodiment 2

[0012] Polyvinyl alcohol 15kg, SiO 2 8kg, sodium hexametaphosphate 0.5kg, alkylphenol polyoxyethylene ether 0.2kg, polyvinylamine 3kg, the balance is water

Embodiment 3

[0014] Polyvinyl alcohol 20kg, TiO 2 10kg, polyacrylamide 0.1kg, polyol 0.1kg, water-based polyurethane 1%kg, water 78.8kg

[0015] The concrete implementation method of the present invention is as follows: the preparation of ink-absorbing layer emulsion, 1. the dispersion of pigment, dispersant is added in water and stirred for 5 minutes, adds pigment and stirs at high speed for 50 minutes to make pigment dispersion liquid. ②Heat the polyvinyl alcohol solution to 55-75°C. ③Add the heated polyvinyl alcohol solution into the pigment dispersion and stir for 30 minutes. ④ Add various additives to the above mixture in turn, stir at a low speed for 5-10 minutes, and after uniformity, lower the temperature to 40-60°C and keep it warm for later use. The ink-absorbing layer emulsion and the antistatic layer are sequentially applied to both sides of the PET substrate by adopting the slope flow extrusion coating and forced drying process with precise coating amount control. The las...

Abstract

The invention discloses an environment-friendly medical ink-jet printing film. The environment-friendly medical ink-jet printing film comprises a PET (Polyethylene Elycol Terephthalate) transparent sheet or semitransparent sheet, wherein a special ink-jet printing ink absorbing layer is arranged on one surface of the PET transparent sheet or semitransparent sheet, and an anti-static layer is arranged on the other surface of the PET transparent sheet or semitransparent sheet; and the special ink-jet printing ink absorbing layer comprises the following components according to mass percent: 10%-20% of polyvinyl alcohol, 5%-10% of a pigment, 0.1%-1.0% of a dispersing agent, 0.1%-0.5% of a non-ionic surface active agent, 1%-5% of a dye-fixing agent and the balance of water. The ink absorbing layer of the environment-friendly medical ink-jet printing film effectively increases the resolution ratio and color reducibility of ink-jet printing images. The anti-static layer is formed by directly coating a thiophene anti-static liquid and effectively prevents specimen page adhesion caused by static electricity in the using process of the ink-jet printing film.

Description

technical field [0001] The present invention relates to the field of inkjet printing film, more specifically, relates to an inkjet printing film suitable for outputting images of various medical diagnosis and treatment results in medical diagnosis and treatment. Background technique [0002] Non-silver salt digital medical imaging printing film is the development direction of modern medical imaging system. Unlike the traditional silver salt photosensitive film, which undergoes a series of cumbersome processes such as developing, fixing, and washing in the darkroom, it will cause environmental pollution and waste water. Unlike dry film, it is not necessary to avoid high temperature, keep away from radiation sources and light sources, and it is expensive and prone to information loss due to secondary exposure fogging. Following the development trend of the times, our company has developed and produced a new type of environmentally friendly medical inkjet printing film, which ...
