二氧化钛纤维的制备方法

Abstract

二氧化钛纤维的制备方法,属于功能纤维材料技术领域。合成聚乙酰丙酮合钛作为前驱体,将化学计量比的四氯化钛、蒸馏水、乙酰丙酮和三乙胺分别稀释于甲醇中,在搅拌和0℃~25℃条件下混合、反应,一步合成聚乙酰丙酮合钛,用四氢呋喃除去副反应物盐酸三乙胺,将聚乙酰丙酮合钛溶于甲醇配制纺丝液,离心甩丝获得前驱体短纤维,干法纺丝获得连续前驱体长纤维,采用高压或常压的水蒸汽热处理技术烧结而得。本发明的拉伸强度100MPa~1.2GPa,直径3μm~20μm,单丝连续长度1cm~50cm或>1m,晶粒粒径5nm~100nm,晶相为锐钛矿相、或金红石相、或两相共存的二氧化钛短纤维或连续纤维。
The producing method of two-oxidation titanium fibre belongs to function fibre material technology scopes. Compose poly-acetamide acetone titanium to be the van-substance. Let chemic dosage of four-chloridize titanium, distilled water, acetamide acetone and three-ethylamine dilute in methanol respectively. Mix them and react when mixing round at 0-25 deg.C. Compose poly-acetyl acet, titanium. Remove hydrochloric three-ethylamine by using four-hydrogen furan. Dissolve poly-acetyl acet, titanium in methanol to make filature liquid. Obtain van-substance short fibre by using acentric swing method. Obtain van-substance long fibre by using dry filature method. And we can obtain two-oxidation titanium fibre by using high pressure or normal pressure vapor heat treatment technique agglomeration. The intension of extend of this invention is 100 MPa-1.2GPa. The diameter is 3um-20um. The one-thread series length is 1 cm-50 cm or higher than 1 m. The crystal diameter is 5 nm-100 nm. The appearance is two-oxide ation short fibre or consecutive fibre with titanium droff-titanium-mine posture or rutile posture or coexistence.
