Description

Technical Field

[0001] The invention relates to the technical field of coatings, and in particular to acrylic ink with metallic texture. Background Art

[0002] Metallic ink is a special type of ink that gives off a metallic sheen when written or drawn. It usually contains tiny metal particles that create a shiny effect on the surface of the paper and is often used to enhance the visual appeal of artwork and calligraphy. Metallic ink is available in a variety of colors, such as gold, silver, copper, etc., and is suitable for a variety of media, including paper, card, fabric, etc.

[0003] Metallic inks are widely used, such as calligraphy and art works, for calligraphy and hand-painted works to add personality and highlights; greeting cards and invitations, especially suitable for festivals and special occasions, to increase visual appeal; packaging design, for product packaging to enhance the product's sense of grade.

[0004] Metallic inks are usually composed of pigments, solvents, and metal particles (such as aluminum powder or other metal minerals). According to the usage scenario, metallic inks can be divided into the following types: water-based metallic inks, which use water as a solvent, have low odor, dry quickly, and are suitable for indoor use; Oil-based metallic inks use oil as a base and have a better sheen, but may take longer to dry; acrylic metallic inks are suitable for a variety of surfaces and are available in water-based or oil-based versions, suitable for painting and crafting.

[0005] The advantages of acrylic ink make acrylic metallic ink more advantageous and its application range is wider.

[0006] However, the current metallic ink has some shortcomings, which are mainly reflected in the fact that the effect after writing has certain shortcomings, such as gray color, smooth surface shrinkage and so on.

[0007] To this end, we need to provide a product with better writing effect based on the current status of acrylic metallic ink. Summary of the invention

[0008] The purpose of the present invention is to provide an acrylic ink with a metallic texture, which can provide a better writing experience for writers.

[0009] Specifically, the present invention adopts the following technical solutions: An acrylic ink with metallic texture, comprising the following components by weight: 40-50 parts of modified acrylic resin, 10-15 parts of modified metal aluminum powder, 5-8 parts of pigment, 30-40 parts of water, and 0.5-1 part of modified silver paste.

[0010] Preferably, the modified acrylic resin is prepared by the following method: Step 1, in a 250mL four-necked flask equipped with a reflux condenser, a constant pressure dropping funnel, a mechanical stirrer and a thermometer, 100 parts of isopropanol and 50-80 parts of a monomer mixture, specifically a mixture of acrylic acid / methyl methacrylate / butyl acrylate in a ratio of 1-2:2:3 are added in sequence, the mixture is stirred evenly, and water bath heating and mechanical stirring are started; Step 2, when the temperature rises to the reflux temperature of isopropanol 82-83°C, after observing the stable reflux of the solvent in the reaction system, add 1-2 parts of the initiator dosage, and stabilize the temperature at 85°C; Step 3, after 15 minutes, add 60-120 parts of the monomer mixture and 2-3 parts of the initiator mixture dropwise for 3 hours, and 30 minutes after the addition is completed, add 30-40 parts of isopropanol and 2-3 parts of the initiator to the reaction system, heat to 88°C and keep warm for 3.5 hours, cool to 60°C, start to add ammonia water dropwise without stopping stirring, and measure the water solubility of the product at any time; when it is completely water-soluble, continue to add ammonia water dropwise until the pH value of the system is 8-9, and then keep warm and stir for 30 minutes to obtain a modified acrylic resin.

[0011] Preferably, the initiator is ammonium persulfate.

[0012] Preferably, the preparation method of the modified metal aluminum powder is: 100 parts of aluminum powder are mixed with 10-15 parts of coating modification liquid, stirred evenly, and then evaporated and dried to obtain the modified metal aluminum powder.

[0013] Preferably, the coating modification liquid is 10 parts of water, 5 parts of polylactic acid, 1 part of polyethylene glycol, 1-2 parts of ammonium sulfate, 3-5 parts of silane coupling agent and 3-4 parts of phthalic anhydride.

[0014] Preferably, the silver paste is prepared by the following steps: The unsaturated polyester resin solution and diethylene glycol butyl ether acetate are mixed in a ratio of 30-50:70, and then stirred and heated to 50-65°C. Then 100 parts of the prepared product are mixed with 10-15 parts of epoxy resin, 10-15 parts of silane coupling agent, 20-25 parts of isopropanol, and 50-80 parts of silver powder, stirred for 3-5 hours, and then set aside.

[0015] Preferably, the silver powder is micron-sized.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The acrylic metal ink of the present invention uses a brand-new modified silver paste, which improves the gray color and smooth surface shrinkage problems of the products on the market; At the same time, this ink uses the combination of aluminum powder and silver powder to produce a matte effect; it has good waterproofness and high adhesion, and can be applied to most materials in life; The prepared ink has a metallic texture after writing, and can bring consumers a completely different visual experience from matte acrylic in the production of handicrafts and greeting cards, especially in model coloring. For example, using acrylic metal on a car model can create a mini version of the car that is extremely similar in color to the real car. DETAILED DESCRIPTION
