摘要:本文根据玻璃化温度设计了铝合金钎焊用粘结剂配方,采用溶液聚合法使用甲基丙烯酸甲酯、丙烯酸丁酯、丙烯酸羟丙酯、丙烯酸等单体合成了水溶性丙烯酸树脂。用蔡恩杯测定其粘度:使用红外测谱仪分析其所含的基团,同时测定了粘结剂的含固量。分析结果表明:当甲基丙烯酸甲酯含量为30%、丙烯酸丁酯53%、丙烯酸羟丙酯5%、丙烯酸12%,溶剂使用正丁醇,且溶剂与单体的比例为1:1.5时,合成的水溶性丙烯酸树脂,其粘度为593.4 cSt,含固量为0.38,其性能及所含基团与进口粘结剂比较接近,可以作为铝合金钎焊用粘结剂;但其透明度和存放性还有待于进一步提高。19882

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.
Keywords : viscosity ; solid content ; soluble acrylic resin ; infrared spectroscopy
