Abstract

A new sand binder system cured by heat is prepared by alkaline decomposition and modification on animal glue binder. To improve some shortages of animal glue such as agglomeration at normal temperature and a low efficiency, an alkaline decomposition process is selected firstly. With the addition of modifiers, binder is modified by copolymerization esterification to get a high strength. In the alkaline decomposition, a good proportion between animal bone glue and water is selected as followed: 5:6,NaOH is used as the catalyst and its addition is 5% to the amount of animal glue, the temperature of alkaline decomposition is 55 and the period of time is 25min.In the modification, some modifiers are selected as :animal glue: glycerin: dextrin : glycol = 100:10:10:10.The modification reaction temperature is 75 and the modification reaction time is 90min. when heated at 200 for 20min , the strength of binder can be built up well. With a addition of 3% to sand, the strength of binder can be 2.63MPa which is high enough to meet the requirement of core-making in foundry. At last, the modification mechanism of animal glue binder is analyzed in theory and the modified binder is characterized by IR..
