Embodiment 1
[0047] An environmentally friendly flame-retardant plastic is prepared from the following raw materials in parts by weight: 100 parts of polyester, 10 parts of flame retardant, 2 parts of plasticizer, 2 parts of antioxidant, and 0.8 part of anti-ultraviolet agent.
[0048] The flame retardant consists of flame retardant A and flame retardant B.
[0049] The flame retardant is composed of flame retardant A and flame retardant B in a mass ratio of 1:5.
[0050] The plasticizer is di-n-octyl phthalate.
[0051] The antioxidant is 2,6-di-tert-butylphenol.
[0052] The anti-ultraviolet agent is 2-hydroxyl-4-n-octyloxybenzophenone.
[0053] The preparation method of environment-friendly flame-retardant plastic comprises the following steps:
[0054] (1) Dry the polyester in an oven at a drying temperature of 110°C and a drying time of 4 hours;
[0055] (2) The screw barrel of the injection molding machine and the injection mold are preheated, the temperature of the screw barrel ...
Embodiment 2
[0060] It is basically the same as Embodiment 1, the difference is only in:
[0061] The flame retardant is composed of flame retardant A and flame retardant B in a mass ratio of 1:6.
Embodiment 3
[0063] It is basically the same as Embodiment 1, the difference is only in:
[0064] The flame retardant is composed of flame retardant A and flame retardant B in a mass ratio of 1:7.
