Embodiment 1

[0030] PVC composite raw materials (parts by weight): 100 parts of polyvinyl chloride resin, 10 parts of PBT resin, 3 parts of acetyl triethyl citrate, 6 parts of calcium carbonate, 1.5 parts of methyl tin mercaptide, 1.5 parts of inorganic flame retardant, Anti-aging agent 0.03 parts.

[0031] The inorganic flame retardant is obtained by stirring and uniformly mixing sodium antimonate, zinc borate and zinc molybdate in a mass ratio of 1:1:1.

[0032] The anti-aging agent is composed of 2,6-di-tert-butyl-p-(dimethylaminomethyl)phenol, 2,4-bis(1,1-dimethylethyl)-5-methylphenol, thiodipropylene Acetate didodecanyl ester is obtained by stirring and mixing uniformly at a mass ratio of 1:1:1.

[0033] Preparation of PVC composite materials:

[0034] (1) Put polyvinyl chloride resin and PBT resin into the mixer, stir for 3 hours at a speed of 600 rpm, then reduce the speed to 70 rpm, then add acetyl triethyl citrate, calcium carbonate, mercaptan Methyl tin, inorganic flame retardant

Embodiment 2

[0037] It is basically the same as Example 1, except that the inorganic flame retardant is obtained by stirring and mixing zinc borate and zinc molybdate in a mass ratio of 1:1. Obtain the PVC composite material of embodiment 2.

Embodiment 3

[0039] It is basically the same as in Example 1, except that the inorganic flame retardant is obtained by stirring and mixing uniformly sodium antimonate and zinc molybdate in a mass ratio of 1:1. Obtain the PVC composite material of embodiment 3.
