摘要
将纳米SiO2分散到环氧丙烯酸酯齐聚体紫外光可固化体系,通过紫外光原位固化制得了纳米SiO2/环氧丙烯酸酯复合材料。结果表明:当w(纳米SiO2)≥3%时,分散体系可稳定贮存,这是由于体系中纳米SiO2与有机基体产生了相互作用,使二者形成一种网络结构,提高了稳定性;复合材料的抗冲击强度提高了3倍多,收缩率减小67.6%;复合材料有一定的透明性,透射波长大于400nm后,透光率大于60%;复合材料中纳米SiO2得到有效的、均匀的分散。
A new kind of nanometercomposites was prepared from UVCSN (ultraviolet light curable system of nanometersilica) under the irradiation of ultraviolet light. The results showed that due to the interactions between the nanometersilica and the organic base, a sort of network structure may be formed and UVCSN can be stockpiled steadily when the content of nanometersilica was exceeded 3%(wt). In this case, the antiimpact intensity of nanometersilica was improved about 4 times and shrinkage ratio was reduced 67.6% compared to neat copolymer. The nanometercomposite had transparency greater than 60% when the wavelength of transmission was over 400nm and the nanometersilica can be dispersed uniformly in nanometercomposite.
