聚醚硅油磷酸酯盐侧链结构与其性能的关系

以自制聚醚硅油与五氧化二磷反应,经中和制得聚醚硅油磷酸酯盐(SiPS),研究其聚醚侧链结构变化对性能的影响。随着聚醚链段中氧乙烯基(EO)含量的增加,分子量的提高,聚醚硅油磷酸酯盐亲水性增加,其表面张力变大,润湿性下降。EO含量的增加使硅油磷酸酯盐在油水界面的吸附力下降,乳化力下降;而聚醚链段分子量提高有助于乳化力提高。EO含量与分子量的增加均可提高硅油磷酸酯盐的吸湿性,改善其抗静电性。

Side chain structure of polyether-silicone phosphates VS its properties

A series of polyether-silicone phosphate salt was prepared with polyether-silicone and P_2O_5 followed by neutralization,and the influence of the structure change of polyether side-chain on the property of the resulting product.With the increase of EO content or the rise of molecular in polyether chain,the surface tension of polyether silicone phosphates(SiPS)increases accompanied with the decrease of their wetting property,due to the improved hydrophilicity of SiPS.With the increase of the EO/PO ratio,the emulsified property of SiPS decreases due to the increased hydrophilicity,but the rise of molecular weight in polyether chain causes improved emulsified property.The rise of either the EO/PO ratio or the molecular weight of polyether chain can improve the water absorption of SiPS,which results in the improved antistatic property.
