Embodiment 1

[0036] The first surface glue formula: (Glue A-1)

[0037]

[0038] Add silica to deionized water, disperse with a tooth disc disperser for 30 minutes at a speed of 1200 revolutions per minute, then add ethylene-vinyl acetate copolymer emulsion, anti-sticking agent, antistatic agent, wetting and leveling agent, and stir Mix uniformly to prepare coating glue A-1.

[0039] The glue is coated on 100μm thick transparent PET (commercially available, manufacturer Hefei Lucky Technology Industry Co., Ltd., model FP1) by means of doctor blade coating, dried with hot air, the maximum temperature of hot air is 90℃, and the coating is measured after drying The thickness is 12μm.

[0040] The second surface glue formula: (Glue B-1)

[0041]

[0042] The preparation method is the same as glue A-1 to obtain glue B-1. Apply the same coating and drying method to the other side that has been coated with glue A-1. After drying, the thickness of the coating is 15μm.

[0043] After coating both sides, p...

Embodiment 2

[0045] The first surface glue formula: (Glue A-2)

[0046]

[0047] The glue solution A-2 was prepared in the same way, and the glue solution was coated on one side of a white PVC material with a thickness of 250 μm by a knife coating method, and a coating with a thickness of 10.5 μm was obtained after drying.

[0048] The second surface glue formula: (Glue B-2)

[0049] Use silica (SD-621, Beijing Aerospace Saide Technology Development Co., Ltd., particle size 13μm) instead of silica YH-200 in glue B-1, and use water-based polyurethane instead of polyacrylic acid in glue B-1 The ester emulsion was coated in the same way to obtain a coating with a thickness of 16 μm.

[0050] After both sides are coated, print medium 2 is prepared, and its performance is measured (see Table 1)

Embodiment 3

[0052] The first surface glue formula: (Glue A-3)

[0053]

[0054]

[0055] The second surface glue formula: (Glue B-3)

[0056]

[0057] According to the same method as in Example 1, two surfaces of a white PET with a thickness of 150 μm were respectively coated to prepare a printing medium 3, and its performance was measured (see Table 1).

Abstract

The invention discloses a laser printing medium, its preparation method and coating. The laser printing medium of the present invention comprises a substrate, and coatings coated on two surfaces of the substrate respectively, i.e. a first surface coating and a second surface coating; wherein, the first surface coating comprises Inorganic pigment, water-based polymer, antistatic agent, water and silicone emulsion and / or emulsified wax, the second surface coating comprises inorganic pigment, water-based polymer, antistatic agent, water and silicone emulsion and / or emulsified wax, the surface roughness Ra value of the first surface coating is 0.08-1.5 μm, and the surface roughness Ra value of the second surface coating is 1.6-3.0 μm. The difference between the surface roughness of the two coatings is not less than 0.6 μm. In addition to obtaining good printing quality, the laser printing medium of the present invention does not jam during continuous high-speed printing, especially when plastic resin such as PET is used as the base material, its advantages can be more manifested.

Description

Technical field [0001] The invention specifically relates to a laser printing medium, its preparation method and coating. Background technique [0002] The laser printer is a kind of print output device. Its working principle is based on electrophotographic technology, that is, the toner undergoes a series of transfers under the action of positive and negative charges to reach the surface of the printing medium, and it is heated by the heat roller (the temperature is usually as high as 180℃) , The carbon powder is solidified under pressure, and finally the required graphic image is formed on the surface of the medium. Among them, color laser printing has good image quality, fast printing speed, image is not easy to fade, and has a long storage time. It is a digital printing method that has developed rapidly in recent years and can be used in different fields, such as advertising, packaging, licenses, medical imaging films, etc. . [0003] With the advancement of technology, the p...
