以正硅酸乙酯为无机前驱体,以甲基丙烯酸β羟乙酯为有机前驱体,采用溶胶-凝胶法制备了硅杂化丙烯酸酯。研究了不同硅含量硅杂化丙烯酸酯的储存稳定性、粘接性能和耐热性能,并利用IR光谱和SEM对硅杂化丙烯酸酯及其固化物的结构进行了表征。结果表明:该硅杂化丙烯酸酯树脂组分相容性良好,固化过程中形成了有机-无机交联网络。当硅含量为0.67~2.01份时,树脂具有较好的粘接性和耐热性能。
Using tetraethyl orthosilicate as inorganic precursor and β-hydroxyethyl methacrylate as organic precursor, the hybrid silica acrylate was prepared by sol-gel method. The storage stability, adhesive properties and heat resistance of silicon hybrid acrylate with different silicon content were studied. The structure of silicon hybrid acrylate and its cured product was characterized by IR spectra and SEM. The results showed that the silicone hybrid acrylate resin had good compatibility and formed organic-inorganic crosslinked network during the curing process. When the content of silicon is 0.67 ~ 2.01, the resin has good adhesiveness and heat resistance.
