Heat-resistant antistatic coating

Abstract

The invention relates to a heat-resistant antistatic coating which is especially applicable to working at high temperature. The heat-resistant antistatic coating provided by the invention can maintain good electrical conductivity and does not influence the properties of manufactured products. The heat-resistant antistatic coating is prepared from 55-65% of polyester resin, 55-65% of epoxy resin, 27-40% of filling material, 4-5% of leveling agent, 3-4% of curing agent, 40-70% of resin, 20-40% of electrically conductive powder, 1-20% of solvent, 1-3% of dispersing aid, 1-5% of titanium white, 0.1-0.3% of coupling agent, 35-55% of acrylic emulsion, 1-4% of graphite powder, 1-4% of carbon black and 45-65% of diluent.

Description

Technical field: [0001] The invention relates to a high-temperature-resistant antistatic coating, which is especially suitable for high-temperature operation. Background technique: [0002] Antistatic coatings are currently mainly used in oil storage and transportation equipment, walls and floors that require cleanliness and antistatic. The application status of antistatic coatings in petroleum storage and floors, the current national standards for pillow static coatings and the future development direction of the coatings. Antistatic coatings are a group of special functional coatings with a volume resistivity within a certain range. Its earliest research record is the conductive adhesive patent published in the United States. In the 1990s, Japan developed silver-based and carbon-based antistatic coatings, which were used in the electronics industry and military fields, but the awareness of electrostatic hazards in the petroleum industry was fully matured in the 1990s.

Problems solved by technology

However, the conductivity will be affected by many factors such as temperature, and some antistatic materials are more expensive, and the impact strength and mechanical properties are reduced, which is poor.
