Abstract

The invention discloses a coating composition for a transferable laser anti-counterfeiting plate and a method for preparing the transferable laser anti-counterfeiting plate. The coating composition comprises the following components in parts by weight: 2-15 parts of polyacrylate resin, 5-10 parts of high-Tg-monomer-containing modified polyacrylate resin, 2-5 parts of hydroxyl-containing polyacrylate resin, 1-3 parts of low polyisocyanate resin, 0.1-0.5 part of aid and 72-82 parts of solvent. The method for preparing the transferable laser anti-counterfeiting plate comprises the following steps: coating the coating composition on a polyethylene glycol terephthalate (PET)-based film, performing die pressing, plating aluminum, coating and transferring a heat-seal adhesive, and preparing a transferable film; stripping the PET-based film on the transferable film, compounding the coating composition to a coil base material, and preparing the transferable laser anti-counterfeiting plate. The coating composition can meet high solvent-resistant and temperature-resistant temperatures in the production process of laser anti-counterfeiting plates. Moreover, the PET-based film used by transferable color steel can be repeatedly used, environment friendliness is promoted, and the production cost is reduced.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a coating composition for a transferable laser anti-counterfeiting board and a preparation method for the board. Background technique [0002] Today, my country's metal packaging is mainly tinplate packaging, and the sales revenue of related industries has already exceeded 50 billion yuan. Tinplate packaging is deeply loved by customers because of its good airtightness, preservation, light protection, sturdiness, strong oxidation resistance, and exquisite printing. It is an international general packaging variety and is widely used in food packaging and pharmaceutical packaging. , daily necessities packaging, instrumentation packaging, industrial product packaging, etc. Traditional tinplate packaging is usually decorated with iron printing, but the iron printing process is cumbersome, and has high requirements for ink adhesion, temperature resistance, and printing ov...
