Abstract

The invention discloses a preparation method and application of a polyphosphazene polymer modified halloysite nanotube composite material with different coating thicknesses. The method includes the following steps: (1) placing an appropriate amount of halloysite nanotubes into acetonitrile, performing ultrasonic dispersion, adding a double-terminal amine substance and triethylamine in sequence, and performing stirring; (2) slowly adding an acetonitrile solution of phosphonitrilic chloride trimer with different concentrations dropwise into the material obtained in the step (1), and performing acondensation polymerization reaction under stirring at 40-80 DEG C for 6-24 h; and (3) washing the material obtained in the step (2) by using anhydrous ethanol, and performing vacuum drying at 40-80DEG C to a constant weight to obtain a pale yellow solid, so as to obtain the composite material.

Description

Technical field [0001] The invention belongs to the technical field of flame-retardant materials, and particularly relates to a preparation method and application of a polyphosphazene polymer modified halloysite nanotube composite material with different coating thicknesses. Background technique [0002] In the new era of rapid development of materials, polymer materials, together with their excellent physical and chemical stability, corrosion resistance, and easy processing and molding, are widely used in marine diving, electronic and electrical, coating adhesives and construction. However, polymer materials have disadvantages such as poor fire resistance and flammability in practical applications, and there are often problems such as improved flame retardant properties accompanied by reduced mechanical properties. [0003] Phosphonitrile polymers are green and environmentally friendly, because the phosphorus and nitrogen on the main chain give them good flame retardant properties...
