Embodiment

[0045] This embodiment provides a high-performance environmental protection water-based conductive antistatic coating, its raw materials and mass percentage content are as follows: non-ionic water-based polyurethane emulsion: 35-50%, graphene: 0.5%-5%, wetting agent: 0.1-0.5%, talcum powder: 10-15%, dispersant: 0.5-1%, anti-flash rust agent: 0.1-0.5%, anti-settling agent: 0.-1%, film-forming aid: 0.5-1.5% , Coupling agent: 0.5-1%, the rest is water.

[0046] Its preparation method is:

[0047] 1) Mix non-ionic water-based polyurethane emulsion with wetting agent, talcum powder, coupling agent and anti-flash rust agent in a disperser and stir at high speed for 0.5 hours to obtain a uniform system;

[0048] 2) Continue to add anti-sedimentation agent, talc powder and graphene to the above homogeneous system and shear at high speed for 1 hour, then move to a grinder and grind until the average particle size is less than 40 μm;

[0049] 3) Pour the ground slurry into the paint m...

Abstract

The invention relates to a high-performance environment-friendly water-based conductive antistatic coating and a preparation method thereof. The coating comprises the following raw material by weight: 35-50% of a nonionic polyurethane emulsion, 0.5%-5% of graphene, 0.1-0.5% of a wetting agent, 10-15% of talcum powder, 0.5-1% of a dispersing agent, 0.1-0.5% of an anti-rust agent, 0-1% of an anti-settling agent, 5-1.5% of a film forming additive, 0.5-1% of a coupling agent and the balance of the water. The invention has the advantages of reasonable design, environment-friendliness, stable performance and good corrosion resistance; a nonionic waterborne polyurethane emulsion has high adhesion, washing resistance and stable performance; and the graphene has good conductivity and strong anticorrosion performance.

Description

technical field [0001] The invention relates to a high-performance environment-friendly water-based conductive antistatic coating and a preparation method thereof, which are mainly used for preventing static electricity. Background technique [0002] With the development of science and technology, all walks of life such as petroleum, chemical industry, and medical treatment are more and more inclined to mechanization and electronics. These factors make the harm of static electricity in society more and more dominant. Static electricity is easy to accumulate on the surface of metal and non-metallic materials, which can cause malfunctions in the operation of instruments and equipment, or break down electronic components, causing accidents such as electric shock, fire or explosion. Therefore, the anti-static requirements of electronic components and equipment are getting higher and higher. [0003] At present, there are many anti-static technical methods. Compared with electro...
