Problems solved by technology
[0003] Polyvinyl chloride (PVC) ink is one of the most widely used. In addition to the damage of concentrated sulfuric acid and concentrated nitric acid, most other inorganic acids, alkalis, most organic solvents, inorganic salts and peroxides are harmful to ink. Polyvinyl chloride (PVC) is not damaged, therefore, polyvinyl chloride ink is a commonly used anti-corrosion material, but the chlorine content in polyvinyl chloride (PVC) is 57%, relatively unstable to heat and light, and the temperature above 50°C and UV radiation will cause chlorine atoms in polyvinyl chloride (PVC) to be lost in the form of hydrogen chloride (HCl). Hydrogen chloride is a gas that is harmful to the environment and is corrosive to metals. Heavy metals will pollute soil and groundwater.

Abstract
The invention discloses halogen-free etching-resistant and electroplating-resistant strippable ink and a preparation method and the application thereof. The halogen-free etching-resistant and electroplating-resistant strippable ink mainly comprises the following materials in parts by mass: 45-60 parts of methyl methacrylate-butyl methacrylate resin, 1-10 parts of styrene-vinyl resin or butane-styrene resin, 25-40 parts of a plasticizer, 1-5 parts of polyurethane acrylic resin, 1-3 parts of a wetting dispersant, 5-7 parts of a pigment dispersant, 1-3 parts of silica, and 0.1-0.3 part of pigment. The halogen-free etching-resistant and electroplating-resistant strippable ink is high in adhering performance, resistant to etching, free from separation during electroplating, good in covering protecting effect, and free from separating and diffusion coating risk. The preparation method is simple in processes, small in loss, and low in cost, meets energy saving requirement, and suitable for wide popularization.
Description
technical field [0001] The invention relates to the technical field of inks, in particular to a halogen-free, etch-resistant, electroplating-resistant strippable ink. Further, the present invention also relates to the preparation method and application of the ink. Background technique [0002] In recent years, heat-curable peelable inks, as temporary protective inks, are mainly used in the insulation coating process of circuit boards, metal plating and etching, touch screens, ITO conductive glass, and ITO films. It is screen-printed on the carrier and formed into a film after heating and curing to protect the parts that do not need to be etched or electroplated, or to prevent the material from being polluted or scratched during the production process. After use, it can be easily peeled off, and it can be peeled off once to keep the surface of the material from contamination. At the same time, it retains the performance of conductive materials, and has the effects of acid re...
