Oil-resistant static-conducting anticorrosive paint and preparation method thereof

Abstract

The invention relates to an oil-resistant static-conducting anticorrosive paint and a preparation method thereof and belongs to the field of chemical industry. The oil-resistant static-conducting anticorrosive paint comprises the following raw materials in part by weight: 50 to 54 parts of liquid epoxy resin, 5 to 9 parts of rutile type titanium oxide powder, 0.5 part of bentonite, 1 to 1.4 parts of polyamide anti-settling agent, 1 part of dispersant, 0.5 part of leveling agent, 0.1 part of antifoaming agent, 20 to 24 parts of conducting mica powder, 3 to 7 parts of superfine talcum powder, 4 to 8 parts of methyl isobutyl ketone (MIBK), 0.3 to 0.7 part of antistatic agent and 28 to 56 parts of dimethylbenzene. The oil-resistant static-conducting anticorrosive paint has the advantages of reasonable formula design, high conductivity, low cost, stable quality and high oil resistance, is difficult to deposit and agglomerate and is easy to disperse and clean.

Description

technical field [0001] The invention relates to an oil-resistant and static-conductive anticorrosion paint and a preparation method thereof, belonging to the field of chemical industry. Background technique [0002] Antistatic coatings provide effective protection for oil transportation and storage equipment. It can not only conduct current to eliminate accumulated static charges, but also prevent equipment from corroding. my country started research on antistatic coatings in the 1990s, and in 1992 formulated the national safety standard GB13348-92 of "Electrostatic Safety Regulations for Liquid Petroleum Products". Standard requirements: anti-static anti-corrosion paint should be used on the inner wall of the storage tank, and the volume resistivity of the paint should be as low as 108Ω (the surface resistivity should be lower than 109Ω). my country has successively developed antistatic coatings based on carbon, which not only eliminates static electricity accidents, but a...

Problems solved by technology

However, many problems have been exposed during the use of antistatic coatings: antistatic coatings based on metal fillers have good electrical conductivity, but are expensive; antistatic coatings based on carbon systems have good electrical conductivity and corrosion resistance, but Easy to deposit and agglomerate, difficult to disperse and clean during production, poor adhesion, prone to cracking, poor oil resistance, affecting product quality, and the color is monotonous, it is difficult to detect hidden dangers early, etc.

In the existing technology, metal fillers and carbon-based conductive media are basically used, such as the coatings disclosed in the application numbers 94105369.5 and 200910219418.0. Metal fillers and carbon-based static conductive coatings are not used, such as the coatings disclosed in the application number 02134219.9. The solutions to these problems are not satisfactory
