Abstract

The invention relates to the technical field of anti-static paint, and discloses anti-static paint for a solid buoyance material substrate surface. The paint comprises the following raw materials in parts by weight: 5 to 8 parts of sodium dodecyl benzene sulfonate, 3.9 parts of absolute ethyl alcohol, 1 to 4 parts of potassium peroxodisulfate, 4.8 to 14.5 parts of pyrrole monomers, 4 to 8 parts ofmethacrylonitrile, 4.1 to 6.1 parts of methacrylic acid, 0.1 to 0.3 part of azodiisobutyronitrile, 3 to 6 parts of tertiary butanol, 1 mL of allyl methacrylate and 2 to 3 parts of polyvinyl alcohol.The paint solves the technical problem that the anti-static paint for the solid buoyance material substrate surface in the prior art cannot effectively reduce the self weight while effectively achieving the anti-static effects.

Description

technical field [0001] The invention relates to the technical field of antistatic coatings, in particular to an antistatic coating for the surface of a solid buoyancy material substrate. Background technique [0002] In recent years, solid buoyant materials have been widely used in marine development equipment such as offshore drilling platforms, oil production risers and underwater operating submersibles. As human beings explore and develop the ocean more and more widely, the demand for solid buoyant materials is also increasing. [0003] However, the commonly used solid buoyancy materials are basically prepared by filling thermosetting resin with hollow microspheres. Since the hollow microspheres used as the filler and the resin used as the matrix are very good insulating materials, the prepared solid buoyancy material also has very good insulation properties, and the volume resistivity is generally between 1012-1015Ω·cm. This insulating material has a very large electro...
