Production method of water-based attapulgite conductive paint

Abstract

The invention discloses a production method of a water-based attapulgite conductive paint. The technical scheme of the invention is characterized in that the production method comprises the following steps: stirring and mixing the ingredients of the water-based attapulgite conductive paint evenly to obtain a mixture; and grinding the mixture in a sanding machine to obtain a semi-finished product, performing vacuum degassing technological treatment on the semi-finished product, and canning to obtain the finished product of the water-based attapulgite conductive paint. The water-based attapulgite conductive paint consists of pasty attapulgite clay, pure acrylic emulsion, a polyaniline / attapulgite nanometer conductive composite, polyethylene glycol, propandiol butyl ether, ethylene glycol, polyoxypropylene glycerin ether and deionized water. The pasty attapulgite clay, polyaniline / attapulgite nanometer conductive composite and pure acrylic emulsion selected by the invention have the advantages of good adhesion, good mechanical properties, better corrosion resistance and excellent mechanical properties; the conductivity of the water-based attapulgite conductive paint with low content is still excellent; and the production method is suitable for the production of the water-based attapulgite conductive paint.

Description

technical field [0001] The invention relates to coatings, in particular to a production method of water-based attapulgite conductive coatings. Background technique [0002] Conductive coatings have the properties of eliminating static electricity and electromagnetic shielding, and are composed of film-forming substances, conductive fillers, solvents and additives. The conductive fillers used in conductive coatings are generally metal powder and carbon powder. Metal powder is expensive, has a large specificity, and is difficult to disperse. However, the color of the coating prepared by carbon powder is black, which seriously affects the appearance of the coating. Therefore, it is urgent to develop a Conductive filler with good conductivity and light color. [0003] Due to its simple preparation method and excellent electrical conductivity, polyaniline is regarded as the most promising conductive polymer material to replace metal powder and carbon powder fillers. However, th...

AI Technical Summary

Problems solved by technology

However, the current use of pure polyaniline as a conductive filler has the following problems in the application of coatings: 1. Poor dispersion, easy to agglomerate, and flocculation after placement, resulting in rough surface of the paint film, poor diffusion and leveling, and difficult to form a conductive network ; 2. To form a conductive coating with better conductivity, a large amount of polyaniline conductive filler must be added. The direct consequence is higher cost, thicker coating and poor adhesion, making it difficult to realize industrial application

[0005] The disadvantage of the above-mentioned patents is that 30-70 mass% silver powder is added in proportion to the technology, which is relatively expensive and unfavorable for popularization and application.
