Analysis and Stady on the Influence of Different Experimental Materials on the Properties of Unsaturated Polyester Resin
Based on general resins,a new modified unsaturated polyester resin with good air drying property,good corrosion resistance and low styrene volatilization was developed in this paper.General purpose resin has defects such as styrene volatility,poor corrosion resistance,poor air drying,easy to form cracks,etc.Adding bicyclopentadiene(DCPD)to modify the resin,the curing speed of the resin is not different,and the resin has good toughness.Because DCPD resin has good compatibility with styrene,the content of styrene can be reduced,and the viscosity of the resin does not change greatly.The new process and properties of industrial bicyclopentadiene(dicyclopentadiene)synthesized unsaturated polyester resin were studied by catalytic hydrolysis addition method.The content of dicyclopentadiene is less than 80％,and various influencing factors are studied to obtain the best main process conditions,which is of great significance to promote the research and production of the new process.
