Novel nickel powder-carbon black conductive paint and preparation method thereof

Abstract

The invention relates to novel nickel powder-carbon black conductive paint and a preparation method thereof. The preparation method comprises the following steps: sequentially adding proper amounts of acrylic resin, 325 amino-acid resin, benzoyl peroxide, styrene and acetaldehyde into a container, and stirring continuously; adding polyethylene wax powder into the solution, and uniformly mixing so as to obtain a primary paint mixture for later use; mixing and finely grinding proper amounts of carbon black and nickel powder by using a grinding pot; adding 15-30% by mass of the nickel powder-carbon black powder into the mixture for later use; and under a normal temperature sealing condition, performing ultrasonic oscillation for 1-2 hours, thereby obtaining the novel nickel powder-carbon black conductive paint.

Description

technical field [0001] The invention relates to a conductive material, in particular to a conductive paint material and a preparation process thereof, belonging to the field of materials. Background technique [0002] The history of paint can be traced back to more than 4,000 years ago. At that time, the working people of our country just utilized vegetable oil (such as tung oil, catalpa oil) and natural raw lacquer to paint the surface of utensils, and formed a protective coating film after drying. By 1500 BC, paint had been used for painting and decoration in caves in France and Spain. In 1500 BC, the Egyptians used dyes such as indigo and madder to make blue and red pigments, but the paint was far from perfect. In the 18th century, due to the development and utilization of linseed oil and zinc oxide, the paint industry developed rapidly. In the 20th century, the paint process has undergone significant development, and paints of various colors with greater adhesion, high...

Problems solved by technology

[0004] Generally speaking, the higher the shielding performance of the electromagnetic shielding material, the better. Adding conductive fibers to the paint can produce conductive paint, but when the content of the conductive fiber is too high, the cost of the conductive paint is high and the service life of the film is short; If carbon black is added, although the cost of carbon black is not high, the conductivity cannot be fully exerted. In order to overcome this problem, the present invention prepares a new type of copper powder-carbon black conductive paint by adding copper powder and conductive carbon black in the paint. , the conductive paint prepared by this method has strong conductivity
