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

[0031] A screen printing peelable UV ink prepared by the following method:

[0032] (1) 20 parts by mass of U25-20d, 15 parts by mass of BR32, 32 parts by mass of vinyl acetate resin (L14 / 60), 4 parts by mass of stearyl 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 are mixed by a high-speed disperser at 30 rpm for 20 minutes to obtain a preliminary mixture;

[0033] (2) The initial mixture is finely ground by a three-roller, and finally through fineness testing (GB / T6753.1-2007), the uniform and fine fluid obtained is the screen printing peelable UV ink. The fineness of the particles in the ink is not more than 5 microns.

Embodiment 2

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 a preparation method and application thereof. The ink is also a functional UV coating material. Background technique [0002] Peelable coating is a special coating that provides protection to the surface of the substrate. It is used in electronic instruments, optical devices, metal materials and other fields to provide temporary protection for the surface of these materials; the coating is also used for the surface of the processing process Protection, and has the characteristics of easy peeling after use, so that the protected surface is free from dirt and damage. It is 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 clear requir...
