Embodiment 1-5
[0044] Embodiment 1-5: A flame-retardant PET and PC composite material, which is prepared by the following steps, and its components and contents are shown in Table 1:
[0045] S0: Treatment of inorganic powder: Dilute 1.5% of the total mass of inorganic powder with absolute ethanol in a water bath at 35-45°C for hydrolysis and dilution, the mass ratio of absolute ethanol to silane coupling agent 8:1, at 15-35°C, add the inorganic powder weighed in proportion while stirring the diluent, continue stirring for 5-10min after all the inorganic powder is added, and then dry at 80°C for more than 4h, Finally, place the dried powder in an airtight container for later use; the silane coupling agent is γ-(2,3-glycidoxy)propyltrimethoxysilane;
[0046] S1: Weigh each component according to the ratio in Table 1, wherein the inorganic powder has been treated in step S0 before use, and dry the weighed PC and PET at 120°C for at least 4 hours, and other components at 50- Dry at 80°C for 2 ho...
Embodiment 9
[0053] Embodiment 9: A composite material of flame-retardant PET and PC. The difference from Embodiment 2 is that the toughening compatibilizer is ethylene-methyl acrylate-glycidyl methacrylate copolymer.
Embodiment 10
[0054] Embodiment 10: A composite material of flame-retardant PET and PC. The difference from Embodiment 2 is that the flame retardant is 0.5 parts of octaphenylcyclotetrasiloxane.
