Acrylate emulsion used for vacuum aluminum plating and laser embossing and preparation method thereof

Abstract

The invention relates to an acrylate emulsion used for vacuum aluminum plating and laser embossing and a preparation method thereof. The emulsion comprises the following components in parts by weight: 1-6 parts of polymerizable carboxylic acid, 18-80 parts of methacrylate, 12-50 parts of acrylate, 5-20 parts of silicon-including cross-linkable monomer, 2-4 parts of polymerizable emulsifier, 0.3-0.7 parts of pH buffer agent, 0.3-0.7 parts of initiator, 0.4-2.5 parts of neutralizer and water, wherein the weight ratio of the water to the total weight of the polymerizable carboxylic acid, the methacrylate, the acrylate, the silicon-including cross-linkable monomer and the polymerizable emulsifier is (1-1.5):1. According to the method provided by the invention, the polymerizable emulsifier is used; the prepared acrylate emulsion does not include a micromolecular emulsifier; the migration of the emulsifier does not exist in a later film forming process; furthermore, polymerizable silane is introduced in a polymerization process; and the degree of cross linking of the acrylate emulsion is improved, so as to give the advantages of high temperature resistance, no migration of the emulsifier, incapability of causing the filling in of a molded blackboard, and the like, to an emulsion film.

Description

Technical field [0001] The invention relates to an environmentally friendly resin and a preparation method thereof, in particular to an acrylic emulsion used for vacuum aluminum plating and laser embossing and a preparation method thereof. Background technique [0002] As countries around the world are increasingly concerned about environmental protection and related pollution prevention and control regulations have become increasingly strict, the resin manufacturing industry has undergone a revolutionary change in the past few years, that is, the original high-polluting solvent-based resin is transformed into a low-polluting resin. [0003] Environmentally friendly resins can include 100% solid resins, solid resins and water emulsions. The viscosity of 100% solid resin is too high, and domestic equipment cannot keep up at this stage, and construction is difficult; solid resin does not contain volatile components such as solvents, but due to the manufacturing process, the molecular...

AI Technical Summary

Problems solved by technology

The viscosity of 100% solid resin is too high, and the current domestic equipment cannot keep up with it, so the construction is more difficult; the solid resin does not contain volatile components such as solvents, but limited by the production process, the molecular weight is not too high, which limits its application range ;Water emulsion, with water as the main dispersion medium, does not contain organic solvents, and the volatile matter is mainly water, but the conventional water-based acrylic emulsion needs to add a small molecule emulsifier, which has a certain impact on the film performance in the later stage, and the presence of water-based acrylic "Hot sticky cold brittle" characteristics, ordinary water-based acrylic resin, not high temperature resistant, can only be used for simple vacuum aluminum plating, can not be suppressed laser effect, otherwise it will cause paste
