聚硅氧烷低聚体制备及其石质文物封护性能研究

A Study on the Synthesis and Performance of Oligomer of Polysiloxane

以烷基硅氧烷、正硅酸乙酯(TEOS)、去离子水等为反应物,加入催化剂,水解聚合,生成聚硅氧烷低聚体,对材料的附着力、憎水性、透气性、耐老化性进行分析测试评价,结果表明,随着烷基链长度的增加,材料的表面封护性能下降。

Siloxane, tetraethoxysilane （TEOS）, and de-ionized water were used with catalysts to produce the oligomer of polysiloxane through hydrolysis and polycondensation. Tests were also carried out to analyze and evaluate the adhesion, hydrophobicity, gas permeability, and aging resistance of such materials. This paper concludes that the properties of surface sealing protect decline as the chain length of Alkyl increases.
