Problems solved by technology

[0002] Silver powder paint is a kind of special pigment added to the paint. It is often used in vehicles, oil tanks, metal pipes and other objects. It is often used for decoration of metal surfaces. At present, oil-based silver powder paint has good silver powder encapsulation, good silver powder arrangement and fast drying speed, but There are disadvantages of high environmental pollution and great harm to human body, while water-based silver powder paint has disadvantages such as poor arrangement of silver powder and slow drying speed.
In addition, water-based silver powder paint also has the defects of poor gloss, poor adhesion, easy to fall off, low impact strength, poor hiding power, and difficult to store.

Abstract

The invention relates to water-based industrial coating, and particularly relates to water-based acrylic silver powder paint suitable for mechanical equipment and a preparation method thereof. The water-based acrylic silver powder paint comprises a water-based self-crosslinking acrylic emulsion, a water-based polyurethane emulsion, a cosolvent, a conventional auxiliary agent, a coalescing agent, an anti-settling agent, aluminum paste, an anti-flash-rust agent, a thickening agent and deionized water. The silver powder paint disclosed by the invention is prepared by matching the water-based self-crosslinking acrylic emulsion with better wrapping property with the proper water-based polyurethane emulsion, and the prepared finished product paint is good in storage stability, high in surface drying speed, high in hardness improvement speed, good in impact resistance and good in silver powder arrangement property. The preparation process is simple, easy to operate and low in production cost,and the working efficiency is improved.
