摘要:
以丙烯酸甲酯(MA)和含氢硅油(PHMS)为原料,制得兼有二者性能的丙烯酸甲酯改性硅油(MA-g-PMMS).对合成产物的结构进行了红外表征,测定了合成产物的粘度指数(VI)、粘温系数(VTC)和表面张力(ST),讨论了PHMS含氢量和粘度对产物性能的影响.用回归分析方法进一步研究了PHMS含氢量和粘度与产物性能的关系.结果表明:PHMS含氢量对MA-g-PMMS性能影响比其粘度显著,且PHMS含氢量和粘度越小,MA-g-PMMS的性能越佳,其VI为420、VTC为0.60、ST为22.0 mN/m;二元
Abstract:
Poly(methylsiloxane) modified bymethyl acrylate, which combines the p roperties ofmethyl ac rylate and poly(methylsiloxane) , was p repared from methyl acrylate and poly(methylhydrosiloxane). The p roduct structure was characterized by IR spectrum. Viscosity index, viscosity-temperature coefficient and surface tension of the p roductwere tested. The influence of viscosity and hydrogen content of poly(meth ylhydrosiloxane) on the p roperties of p roductwas discussed, and the relation between viscosity and hydro gen content of poly (methylhydrosiloxane) and viscosity index, viscosity-temperature coefficient and sur face tension ofmethyl acrylate modified siloxane was analyzed by regular regression and multip le regres sion with two variables. The results indicate that the hydrogen content of poly(methylhydrosiloxane) have more importent effect than its viscosity on methyl acrylate modified siloxane. The smaller the viscosity and hydrogen content of poly(methylhydrosiloxane) are, the better the p roduct p roperties. The viscosity index was 420, the viscosity-temperature coefficientwas 0.60 and the surface tension was 22.0mN /m. The re gression equations were effective and accurate, and the absolute values of standard error of viscosity-tem perature coefficient and surface tension were within the limit of 0.005 8 and 0.069 1 respectively.
