CN201310670377.3 discloses an aging oil demulsifier and a preparation method thereof. The invention belongs to the technical field of petroleum processing. An aging oil demulsifier is composed of a mixed acid, a demulsifier monomer and an initiator. : (0.5-1.5), the molar ratio of the mixed acid to the demulsifier monomer alkyl phenolic resin-polyoxypropylene polyoxyethylene ether is (0.5-1.7): (0.5-1.5), the initiator lauroyl peroxide is mixed 8-12% of acid mass. Its preparation process: mixing acid and demulsifier monomer alkyl phenolic resin-polyoxypropylene polyoxyethylene ether, adding initiator dilauroyl peroxide, polymerizing at 70-100 ℃, polymerization time 1-4h, then The temperature is raised to 100-150°C for esterification, and esterification is carried out for 3-7h to obtain an aging oil demulsifier. The invention has the characteristics of simple components, simple process, convenient preparation, rapidity and high efficiency, low cost, less dosage, less toxic and side effects, wide application range, good demulsification effect and the like.
CN201510447852.X discloses a high-performance quartz glass, which is composed of quartz glass, an initiator, a wear-resistant agent, a toughening agent, an impact-resistant modifier, a dispersant and a molecular weight regulator, and the initiator is dilaurin peroxide acyl, the abrasion-resistant agent is silicone oil, the toughening agent is polyvinyl butyral, the impact-resistant modifier is styrene-butadiene-styrene block copolymer, and the dispersant is It is polyethylene glycol stearate, and the molecular weight regulator is butyl 3-mercaptopropionate. The invention has the advantages of high processing efficiency, good toughness, high strength, wear resistance, scratch resistance and good quality by adding initiator, wear-resistant agent, toughening agent, impact-resistant modifier, dispersant and molecular weight regulator to the quartz glass. specialty.
CN201711069456.3 discloses a preparation method of a high-efficiency non-silicon oil type defoamer and its application in lubricating oil. The toluene solvent dissolving a certain amount of initiator dilauroyl peroxide is heated to 60~100℃ under the protection of argon, and then the mixed monomer is added dropwise. The reaction is carried out for 1~2h, and the copolymer product is obtained after the reaction is completed. The copolymer product is diluted with environmentally friendly solvent oil D110 to make the mass fraction of the copolymer product 10%~20%. Fully stirring for 0.5 to 1.0 hours at min speed to obtain a high-efficiency non-silicon oil type defoamer, the invention can effectively inhibit the generation of lubricating oil foam, is easy to disperse, has little influence on the air release of lubricating oil, and has good anti-foaming effect on low viscosity.
