Aminoethylpiperazine is a derivative of piperazine. This ethyleneamine contains three nitrogen atoms; one primary, one secondary and one tertiary. It is a corrosive liquid and can cause second or third degree burns. Aminoethylpiperazine can also cause pulmonary edema as a result of inhalation. Uses include inhibition of corrosion, epoxy curing, surface activation, and as an asphalt additive. When used as an epoxy resin curing agent, it is usually used in conjunction with other amines as an accelerator as it only has 3 amine hydrogens for cross-linking.

Silicone rubber based thermal failure protection material and preparation method and application thereof
ActiveCN110093037AProlong vulcanization induction periodIncreased scorch safetyPower batteryVulcanization
A silicone rubber based thermal failure protection material and a preparation method and application thereof are provided. The material includes 100 parts of epoxidized silicone rubber, 0.5-10 parts of a vulcanizing agent, 0.1-8 parts of a vulcanization regulator, 2-40 parts of a flame retardant, 5-80 parts of a plasticizer and 5-100 parts of a reinforcing agent. The epoxidized silicone rubber isprepared by epoxidizing silicone rubber containing unsaturated double bonds with an epoxidizing agent. The vulcanizing agent is passivated N-aminoethyl piperazine and is prepared by adding N-aminoethyl piperazine into a kneading machine, feeding carbon dioxide and performing mechanical mixing. The vulcanization regulator is dialkyldithiophosphate. The material has excellent fireproofness, flame retardance, heat insulation performance, electric breakdown resistance, and the like, and is controllable in volume expansion so that the material is a thermal failure protection material with excellentcomprehensive performance, can be used for power batteries, modules thereof and other fields, and has a good application prospect.

Organic lithium soap composite urea-based lubricating grease and preparation method thereof
ActiveCN112080328AImprove extreme pressure and anti-wear performanceImprove mechanical propertiesThickenersLithium soapOrganic acid
The invention relates to organic lithium soap composite urea-based lubricating grease with excellent extreme-pressure wear resistance and a preparation method thereof, in particular to novel organic acid lithium soap composite urea-based lubricating grease containing an amino-containing saturated dinitrogen-containing heterocyclic compound and a preparation method of the novel organic acid lithiumsoap composite urea-based lubricating grease. The product is prepared from the following specific raw materials, by weight: 65-90% of base oil, 5-20% of organic lithium soap, and 3-12wt% of a thickening agent. According to the novel organic lithium soap composite urea-based lubricating grease, by introducing the N-aminoethyl piperazine and the organic lithium compound, the extreme-pressure wear resistance and the mechanical stability of the grease are improved on the basis of keeping the original properties of the urea-based lubricating grease unchanged, so that the service life of the lubricating grease under a bearing condition is prolonged. And the lubricating requirements of bearings and equipment under the conditions of frequent shearing and heavy load can be met.
