Problems solved by technology

Generally, acrylic resin, polyurethane resin, etc. are mostly used as color layer resins, and these polymers are prone to disadvantages such as unevenness and large color difference during coating due to their high viscosity and low transparency. There are often many problems such as incompatibility between the chromatographic resin and the dye toner, association and sedimentation, etc.

Abstract

The invention belongs to the field of high polymer materials and relates to alumite chromatographic dye containing a hyperbranched polymer. The alumite chromatographic dye consists of the following components in parts by mass: 20-40 parts of acrylic resin, 20-40 parts of polyurethane resin, 1-5 parts of other resins, 7-20 parts of dye toner, 1-10 parts of hyperbranched polymer, 0.5-1.0 part of auxiliaries and 60-80 parts of solvent. The invention also discloses a preparation method of the alumite chromatographic dye containing the hyperbranched polymer. The preparation method comprises the following steps: putting an appropriate amount of solvent to a reaction kettle, and keeping the temperature in the kettle to 25-60 DEG C; putting the dye toner, the hyperbranched polymer and the auxiliaries to the kettle at one step and stirring for 1-4 hours; adding the acrylic resin, the polyurethane resin and other resins in sequence, controlling the temperature to 15-70 DEG C and stirring for 2-6 hours; finally enabling the materials to flow into a storage tank through a kettle body device for later use, wherein the internal temperature of the storage tank is 10-40 DEG C. The hyperbranched polymer has a three-dimensional spherical space structure, contains a large amount of polar and non-polar functional groups in chain segments and at the chain ends, has excellent dissolving property and low viscosity and has the capability of improving the problem that resin and dye toner are insoluble to each other in alumite chromatographic dye.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to an anodized aluminum color layer dye containing a hyperbranched polymer and a preparation method thereof. Background technique [0002] Due to its unique metallic texture, strong bumpy touch, and clear patterns, anodized aluminum hot stamping products have long become an important means of making high-end packaging materials and anti-counterfeiting marks, and these all depend on the information layer of anodized aluminum. The anodized aluminum information layer is also called the anodized aluminum color layer. It is named for its variety of colors. It is the main body of the anodized aluminum bronzing foil. It is usually made of a mixture of color layer resin and dye toner. It is formulated after dissolving in an organic solvent. It can be dyed and directly coated on the anodized aluminum release layer, so it is necessary for the color layer resin to have better compatibility with ...
