preparation example Construction

[0026] The embodiment of the present invention also provides a method for preparing a high imitation electroplating bonding silver powder coating, comprising the following steps:

[0027] S1. Weighing ingredients: Weigh carboxyl-terminated polyester resin and isocyanate triglycidyl ester in parts by weight

[0028] Silicone resins, terpene resins, polyacrylates, benzoins and optical brighteners.

[0029] S2. Pre-mixing: Put the weighed raw materials into a high-speed mixer and mix them evenly. The temperature in the high-speed mixer is set at 45-55°C.

[0030] S3. Melt extrusion: put the mixed and stirred raw materials into a screw extruder to melt and homogenize, and extrude and tablet into semi-finished products.

[0031] S4. Grinding: put the semi-finished product into a grinder and grind it into a powder with an average particle size of 25-40 μm.

[0032] S5. Bonding: The powdery semi-finished product is first separated from the ultrafine powder by the separator, and the...

Abstract

The invention discloses high-imitation electroplating bonding silver powder paint which comprises the following components in parts by weight: 80-90 parts of terminal carboxyl group polyester resin, 6-8 parts of isocyanate triglycidyl ester, 10-15 parts of organic silicon resin, 5-10 pars of terpene resin, 1-3 parts of polyacrylate, 0.3-0.7 part of benzoin, 0.5-1 part of a fluorescent whitening agent, 1-2 parts of a bonding aid and 0.6-1 part of coating type aluminum powder. The invention further provides a preparation method of the high-imitation electroplating bonding silver powder paint. The preparation method comprises the following steps: weighing and blending materials, premixing the materials, performing melting extrusion, grinding, bonding, screening, and packaging a finished product, thereby obtaining the high-imitation electroplating bonding silver powder paint. By adopting the high-imitation electroplating bonding silver powder paint and the preparation method thereof, effects of high smoothness, high clarity, high brightness and high leveling properties of an electroplated surface are achieved by adjusting the melting viscosity, clarity, surface tension, glass transition temperature, bonding temperature, bonding time, bonding speed and powder flowability of a formula.

Description

【Technical field】 [0001] The invention relates to the technical field of powder coatings, in particular to a high imitation electroplating bonding silver powder coating and a preparation method thereof. 【Background technique】 [0002] Powder coating exists in the state of fine powder. It is a new type of solvent-free 100% solid powder coating. It is solvent-free, pollution-free, recyclable, environmentally friendly, saves energy and resources, reduces labor intensity and mechanical strength of the coating film. advanced features. The powder coating is sprayed on the surface of the coated object in powder form, melted and leveled by baking, and solidified to form a film. Due to the advantages of improving coating performance, reducing costs, and eliminating the generation of volatile organic compounds, powder coatings have been continuously and rapidly developed. [0003] Metal powder coatings refer to various powder coatings containing metal pigments (such as: copper-gold ...
