根據玻璃化溫度設計了鋁合金釬焊用粘結劑配方,采用溶液聚合法使用丙烯酸丁酯、甲基丙烯酸甲酯、丙烯酸、丙烯酸羥丙酯、丙烯酰胺等單體合成了水溶性丙烯酸樹脂

摘要:本文根據玻璃化溫度設計了鋁合金釬焊用粘結劑配方,采用溶液聚合法使用丙烯酸丁酯、甲基丙烯酸甲酯、丙烯酸、丙烯酸羥丙酯、丙烯酰胺等單體合成了水溶性丙烯酸樹脂。用蔡恩杯測定其粘度:使用紅外測譜儀分析其所含的基團,同時測定了粘結劑的含固量。分析結果表明:當甲基丙烯酸甲酯含量為30%、丙烯酸丁酯52%、丙烯酸羥丙酯5%、丙烯酸12%,丙烯酰胺1%,溶劑使用正丁醇,且溶劑與單體的比例為1:1.5時,合成的水溶性丙烯酸樹脂,其粘度為593.4 cSt,含固量為0.38,其性能及所含基團與進口粘結劑比較接近,可以作為鋁合金釬焊用粘結劑;但其透明度和存放性還有待于進一步提高。35656

Study on the synthesis of water-solubility acrylic resinbinder
Abstract: Based on the glass transition temperature ,the adhesives formulations of  aluminium alloy brazing were designed. Using aqueous solution method, water-
soluble acrylic resins were synthesized with polymerization of methyl methacrylate and acrylic acid butyl acetate, hydroxypropyl acrylate esters and acrylic monomers .. The viscosity of water-soluble acrylic resins was measured by Zion Cup. Using an infrared spectrometer ,the group of water-soluble acrylic resins was analysised. And the amount of the binder solids of water-soluble acrylic resins was determinated . The results showed that: when the methyl methacrylate content of 30% , 53% butyl acrylate , propyl acrylate, 5% hydroxypropyl acrylate, 12% n-butanol solvent , and the ratio of solvent to monomer is 1:1.5 , synthetic water-soluble acrylic resin having a viscosity of 593.4 cSt, the amount of solids was 0.38 , the binder contained in the group close to the inlet can be used as the binder for the brazing of aluminum alloy ; But transparency and storage properties should be further improved.
