本文利用化学组成相同、比表面积相近的玻璃粉及玻璃纤维,对三(二异辛基焦磷酰氧基)钛酸酯(TTOPP-38)进行吸附,并以不同条件进行洗涤表面。测定了粉末试样中P的X光萤光强度;同时对已知AlPO_4含量的AlPO_4玻璃粉混合物,测定P含量与P的X光萤光强度的关系,由此得到玻璃表面对TTOPP 38的吸附能力。结果表明,被玻璃表面牢固吸附的TTOP-38是极微量的,约为TTOPP-38在玻璃表面总沉积量的10%以下,该结合层厚度仅为40～50A。对不同纤维试样制得的复合材料强度测定结果表明,材料界面上的TTOPP-38,以结合强度较弱的物理缠结与基体相连,故即使是极微量的吸附层,也会影响材料的弯曲强度。由于所吸附的TTOPP-38分子有良好的柔性,故该吸附层有良好的变形能力,使复合材料的冲击强度有所提高。
In this paper, Tris (dioctyloctylphosphorothioate) titanate (TTOPP-38) was adsorbed by glass powder and glass fiber with the same chemical composition and similar specific surface area, and the surface was washed under different conditions. The X-ray fluorescence intensity of P in the powder sample was measured. At the same time, the relationship between the P content and the X-ray fluorescence intensity of P was determined for the AlPO 4 glass powder mixture with known AlPO 4 content to obtain the adsorption of TTOPP 38 on the glass surface ability. The results show that TTOP-38, which is firmly adsorbed on the glass surface, is a trace amount of about 10% of the total deposition on the glass surface of TTOPP-38, and the thickness of the bonding layer is only 40-50A. The strength of the composites prepared from different fiber samples showed that the TTOPP-38 on the material interface was connected to the matrix by physical entanglement with weaker bonding strength, so even a trace amount of the adsorbed layer could affect the Bending strength. As the adsorption of TTOPP-38 molecules have good flexibility, so the adsorption layer has a good deformation capacity, the impact strength of the composite has been increased.
