Dibutyl sebacate (DBS) is an organic chemical, a dibutyl ester of sebacic acid. Its main use is as a plasticizer in production of plastics, namely cellulose acetate butyrate, cellulose acetate propionate, ethyl cellulose, polyvinyl butyral, polyvinyl chloride, polystyrene, and many synthetic rubbers (especially nitrile rubber and neoprene) and other plastics. It can be used for plastics in use in the food packaging industry, in plastics used for medical devices, and for pharmaceutical applications, e.g. as a plasticizer for film coating of tablets, beads, and granules. It is also used as a lubricant in shaving lotions, and a flavoring additive in non-alcoholic beverages, ice cream, ices, candy, and baked goods. It provides excellent compatibility with a range of plastic materials, superior properties at low temperatures, and good oil resistivity. Its other names include Morflex, Kodaflex, polycizer, Proviplast 1944 and PX 404. Dibutyl sebacate is also used as a desensitizer in Otto fuel II, a torpedo monopropellant.
Gradient flame-retardant explosion suppressant special for high-energy-density ternary lithium battery and preparation method of gradient flame-retardant explosion suppressant
PendingCN121022434ALi-accumulatorsSecondary cells servicing/maintenanceDimethyl methylphosphonateDibutyl sebacate
The invention discloses a special gradient flame-retardant explosion suppressant for a high-energy-density ternary lithium battery, and relates to the technical field of safety protection of new energy batteries, the gradient flame-retardant explosion suppressant comprises the following components by mass: 30% of trimethyl phosphate, 16% of dimethyl methylphosphonate, 13% of triphenyl phosphate, 32% of a solvent, and 9% of a composite stabilizer; the compound stabilizer is prepared from 2, 6-di-tert-butyl-4-methylphenol, diisooctyl adipate and dibutyl sebacate according to the mass ratio of 2 to 1 to 1. The invention also provides a preparation method of the gradient flame-retardant explosion suppressant. Through formula optimization, especially adjustment of the composite stabilizer and reinforcement of a raw material pretreatment process, the explosion suppressant can be stably stored and operated within the range of-40 DEG C to 50 DEG C, the application limitation in extremely cold and high-temperature areas is solved, and the explosion suppressant is suitable for most of extreme temperature environments in the world.

Antistatic release film
An antistatic release film, comprising a substrate layer, an antistatic coating, and a release agent coating. The antistatic coating is located between the release agent coating and the substrate layer; the antistatic coating is obtained by drying a coating liquid; and the coating liquid is composed of the following components in parts by weight: 100 parts of polyurethane resin, 40-60 parts of polyvinyl alcohol, 2-4 parts of sodium octyl sulfate, 1-3 parts of N-ethyl-N—(3-sulfopropyl)-3-methylaniline sodium salt, 8-12 parts of dibutyl sebacate, 40-60 parts of n-butanol, 20-30 parts of isobutyl acetate, 0.8-1.5 parts of hydroxyethyl cellulose, 0.3-0.8 part pf 3-acetylbenzoic acid, 0.2-0.8 part of triethylenetetramine, 0.5-1.2 parts of a silane coupling agent, 0.5-1 part of an antioxidant, and 0.6-2 parts of a leveling agent. The antistatic release film enables the surface resistance of the antistatic coating in the antistatic release film to be almost unchanged after 200 days, thereby improving the performance reliability of the antistatic release film.
