Further, the synthetic method of OVi-POSS (the eight vinyl silsesquioxanes) nano particle is：By vinyl
Trimethoxy silane is dissolved in acetone, is uniformly mixed, and concentrated hydrochloric acid is added dropwise and deionized water mixed solution is obtained in 40 DEG C of reflux 48h
White solid particle is filtered and is dried in vacuo through methylene chloride and acetone mixed solution recrystallization at 60 DEG C with ethanol washing
To white crystal, as OVi-POSS.
The present invention provides a kind of preparation methods of PET composite material, include the following steps：
(1) OVi-POSS and fire retardant PACP are dissolved in a small amount of tetrahydrofuran solution in varing proportions, ultrasonic vibration makes it
Uniformly mixing, obtains the mixed solution of high concentration；
(2) the PET polyester slice of certain mass is added, after evenly mixing, solution is molten through 80 DEG C of vacuum drying 12h drying
Agent obtains the OVi-POSS/PACP/PET fire-retardant master granule of pre-wrapped.
(3) extruding pelletization after the fire-retardant master granule of different proportion being blended with PET slice through miniature conical double screw extruder,
OVi-POSS/PACP/PET composite material is made.
(4) particle is squeezed out through 120 DEG C of vacuum drying 4h, using injection molding machine injection molding.
Technical solution of the present invention has the following advantages that；
(1) using vinyltrimethoxysilane as raw material, good heat-resisting feeding stability is shown；
(2) OVi-POSS nano particle and fire retardant PACP are coated on PET slice together using Solutions Solution is pre-dispersed
On, then through melt blending, the degree of scatter of POSS nano particle is improved, improve the breaking strength of PET matrix；
(3) addition of OVi-POSS improves matrix crystalline rate and crystallizing power, improves the glass transition temperature and heat of PET
Stability；
Specific embodiment
