Problems solved by technology

This kind of feature is obviously difficult to meet the higher requirements of the stripping process on the mechanical properties of the cured film itself because the cured film does not have sufficient strength and toughness for temporary surface protection applications that require good strippability of the cured film.

Embodiment 1

[0038] A kind of screen printing peelable UV ink, prepared by the following method:

[0039] (1) 20 parts by mass of U25-20d, 15 parts by mass of BR32, 32 parts by mass of vinyl chloride resin (L14 / 60), 4 parts by mass of octadecyl methacrylate, 6.5 parts by mass of dioctyl adipate, 3 parts by mass of ITX, 2 parts by mass of EDB, 0.6 parts by mass of KS66, 0.5 parts by mass of phthalocyanine blue and 2 parts by mass of talc powder were mixed by a high-speed disperser at a speed of 30 rpm for 20 minutes to obtain an initial mixture;

[0040] (2) The initial mixed liquid is finely ground by a three-roller machine, and finally passed through the fineness test (GB / T6753.1-2007), and the obtained uniform and fine fluid is the peelable UV ink for screen printing. The fineness of the particles in the ink is not greater than 5 microns.

Embodiment 2

[0042] A kind of screen printing peelable UV ink, prepared by the following method:

[0043](1) 15 parts by mass of U25-20d, 5 parts by mass of BR32, 50 parts by mass of vinyl chloride resin (CP427), 2 parts by mass of octadecyl acrylate, 3 parts by mass of PEG600DA, 12 parts by mass of dioctyl sebacate , 1.2 parts by mass of ITX, 0.8 parts by mass of EDB, 0.3 parts by mass of KS66 and 0.5 parts by mass of phthalocyanine blue pigment were mixed at a speed of 30 rpm for 20 minutes by a high-speed disperser to obtain an initial mixture;

[0044] (2) The initial mixed liquid is finely ground by a three-roller machine, and finally passed through the fineness test (GB / T6753.1-2007), and the obtained uniform and fine fluid is the peelable UV ink for screen printing. The fineness of the particles in the ink is not greater than 5 microns.

Embodiment 3

[0046] A kind of screen printing peelable UV ink, prepared by the following method:

[0047] (1) 10 parts by mass of U25-20d, 30 parts by mass of BR32, 20 parts by mass of vinyl chloride resin (L3112), 15 parts by mass of octadecyl acrylate, 3 parts by mass of PEG600DA, 12 parts by mass of dioctyl sebacate , 6 parts by mass of ITX, 4 parts by mass of EDB, 2 parts by mass of KS66 and 2 parts by mass of talcum powder were mixed for 20 minutes at a speed of 30 rpm by a high-speed disperser to obtain an initial mixture;

[0048] (2) The initial mixed liquid is finely ground by a three-roller machine, and finally passed through the fineness test (GB / T6753.1-2007), and the obtained uniform and fine fluid is the peelable UV ink for screen printing. The fineness of the particles in the ink is not greater than 5 microns.

Abstract

The invention belongs to the field of functional fine high-molecular materials, and discloses screen printing peelable UV (ultraviolet) ink as well as a preparation method and application of the screen printing peelable UV ink. The UV ink consists of 20-40 mass parts of aliphatic polyurethane acrylate prepolymer, 20-50 mass parts of vinyl chloride-vinyl acetate resin, 2-15 mass parts of alkyl acrylate, 8-15 mass parts of a solubilizer, 2-10 mass parts of composite photoinitiator, 0.3-2 mass parts of a defoaming agent KS66, 0-0.5 mass part of pigment and 0-2 mass parts of talc powder. The components in the ink have a synergistic effect, so that a cured film formed after the ink is cured is balanced in strength, toughness and adhesion, has good surface protection property and peelability and does not have residue during peeling after being used.

Description

technical field [0001] The invention belongs to the field of functional fine polymer materials, and relates to a screen printing UV ink, in particular to a screen printing peelable UV ink and its preparation method and application. The ink is also a functional UV coating material. Background technique [0002] The strippable coating is a special coating that provides protection to the surface of the substrate. It is used in the fields of electronic instruments, optical devices, metal materials, etc. to provide temporary protection for the surface of these materials; the coating is also used for the surface of the process Protective, and has the characteristics of easy peeling after use, so that the protected surface is free from dirt and damage. It is widely used in the fields of ITO glass, printed circuit boards, optical fibers, spacecraft, aircraft, various precision instruments and special crafts, etc. There are applications. [0003] In actual use, in addition to the cl...
