Abstract

The invention relates to an organic silicon function material which is characterized by comprising an organic silicon polyether ketone functional polymer material represented by the following general formula (1), wherein R in the general formula (1) represents H, halogen, Cl-C20 alkyls and C1-C20 naphthenic bases or C1-C20 aryls; R1 or R2 represents the Cl-C20 alkyls, the C1-C20 naphthenic bases, the C1-C20 aryls, C1-C20 alkoxys and C1-C20 cycloalkyloxys, or C1-C20 aryloxys; and the relative number-average molecular weight of the organic silicon polyether ketone functional polymer material ranges from 5000 to 100000. The invention also discloses a preparation method. The organic silicon polyether ketone functional polymer material has high temperature and low temperature resistance and combines the excellent performances of organic silicon polymer materials and polyether-ether-ketone.

Description

technical field The invention belongs to the field of organosilicon functional materials, and in particular relates to the preparation of high-temperature-resistant organosilicon functional materials and a preparation method thereof. Background technique Polyetheretherketone (PEEK) is a high-performance engineering plastic successfully developed by the British ICI company in 1977 and officially produced and sold in 1980. The repeating unit of PEEK contains 19 carbon atoms, 12 hydrogen atoms and three oxygen atoms, the highest crystallinity can reach 48% at room temperature, the average molecular weight is 30000, and the weight average polymerization degree (DPW) is 104. Since the macromolecular chain of PEEK contains a rigid benzene ring structure, a flexible ether bond and a carbonyl group that enhances intermolecular interaction, PEEK has a regular structure and excellent mechanical properties, heat resistance, oxidation resistance, radiation resistance and chemical corro...
