Self-sealing coatings for fuel pipelines
Fuel leakage accidents of storage facilities and pipelines are one of greatest threats to the environment, life safety and economics. Appling self-sealing coating to pipe surface is an economical and effective method to prevent the fuel leakage. Now a high oil-absorption resin was designed and synthesised by suspension polymerisation. The oil-absorption performance and oil-absorption volume expansion ratio of the high oil-absorption resin for gasoline, kerosene, and diesel were characterised, respectively.
Excellent expanding in volume performance
The saturated absorption rate of the high oil-absorption resin for gasoline reached 11.14 g/g, and the volume of the high oil-absorption resin expanded to 6 times when the absorption was saturated. The high oil-absorption resin, as a functional filler to polyurethane resin, exhibited excellent expanding in volume performance to seal the hole of the composite coating. The composite coating with 25 wt% of the high oil-absorption resin sealed a hole of 1.5 mm in diameter in 1 min. As A bottle with filled by kerosene was perforated by a needle with 3 mm in diameter, the composite coating with 25 wt% of the high oil-absorption resin was successfully instantaneous sealed the leak.
The study has been published in Progress in Organic Coatings, Volume 166, May 2022.
Resins for Water-borne Coatings
Expand your knowledge and get fully acquainted with the various aspects of water-borne coatings - from production to properties to special features of their use! With the slow change from solvent-borne resins and coatings to water-borne coatings "Resins for waterborne coatings" is a must-read for any formulator wanting to expand their knowledge. The authors discuss important aspects of the "solvent-to-water-transition" of the past 40 to 50 years, take a deep dive into the key aspects and theories behind the production, properties and applications of these resins as well as providing an overview of how they are currently used in water-borne coatings.
