Add deionized water and anionic surfactant to the reactor, stir and dissolve, heat to 80 ℃, and start adding the first layer of monomer methyl acrylate and a certain amount of ammonium persulfate as initiators. React at 80-90 ℃ for 10 minutes. Start adding the second layer of monomer (methyl acrylate: styrene: butyl diethylene glycol diacrylate=100:25:1), then add a small amount of initiator methyl persulfate, and add a certain amount of emulsifier and initiator. React at around 80 ℃ for 40 minutes. After adding, heat up to 90-100 ℃ and keep it warm for 1 hour to obtain the product.
| use | BT modified propylene resin emulsion has fine particles, good storage stability, excellent leveling property, strong adhesion and good film-forming mechanical and mechanical properties. The coating is soft, strong and flexible, especially suitable for light leather coating. BT872 and BT873 are used for finishing the middle and top layers of high-grade clothing leather and all kinds of soft leather. After finishing, the grain surface is flat and thin, plump and soft. The coating is firm and resistant to falling, non-cracking slurry, moderate luster, strong dermis, dry and wet resistance, embossing non-stick roller, and clear grain. BT902 and BT903 are used for finishing the middle and top layers of high-grade leather. In addition to maintaining the excellence and courage of BT872 and BT873, the strength, brightness, dry and wet rubbing resistance of the adhesive film have been improved. |
| production method | add deionized water and anionic surfactant into the reaction kettle, stir and dissolve, heat to 80 ℃ to start adding the first layer of monomer methyl acrylate and a certain amount of ammonium persulfate as initiator. The reaction was carried out at 80~90 ℃ for 10min. Start adding a second layer of monomer (methyl acrylate: styrene: diethylene glycol butyl diacrylate = 100: 25: 1), add a small amount of initiator methyl persulfate, and add a certain amount of emulsifier and initiator, and react at about 80: 40min. After adding, the temperature is raised to 90~100 ℃, and the temperature is kept for 1h to obtain the product. |
