【摘要】 通过对包括三羟甲基丙烷、季戊四醇及乙二醇这几种不同的多元醇合成的聚酯,利用有机硅中间体改性成膜后,对基材的附着力、硬度、柔韧性所做的探讨,可知在硅含量相同时,乙二醇的附着力最好,且柔韧性也最好,但耐热性能最差,在综合考虑的基础上,三羟甲基丙烷的性能最好。更多还原

【Abstract】 Through studying adhesive strength,hardness and soft tenacity of membrane of fundamental material,which includes trihydroxypropanc,quaternary alcohol and cthylcne glycol,after an organic silicon intermediate product is used to change the properties of these several polybasic alcohol syntheticed polyester resin,it is known that the content of silicon is equal,adhesive strength of cthylcne glycol is the best,and soft tenacity is the best,too.But heat resistance is the worst.On the basic of comprehensive consideration,the properties of trihydroxypropanc are the best.更多还原
