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.

Abstract

The invention discloses environment-friendly flame-retardant plastic as well as a preparation method and an application thereof. The environment-friendly flame-retardant plastic is prepared from the following raw materials in parts by weight: 90-110 parts of polyester, 5-15 parts of a flame retardant, 2-5 parts of a plasticizer, 1-3 parts of an antioxidant and 0.5-1 part of an anti-ultraviolet agent. The flame retardant is formed by compounding an N-phosphorus compound substituted phosphine imine type flame retardant and a phosphonate type flame retardant, and compared with the prior art, theenvironment-friendly flame-retardant plastic prepared by the invention has the advantage that the preparation process flow is simple. The flame retardant is good in performance and has little influence on the mechanical property of the material, so that the application range of the plastic is well widened.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an environmentally friendly flame-retardant plastic, a preparation method and an application. Background technique [0002] Polyester plastic is a heterochain polymer containing ester groups in the main molecular chain prepared by polycondensation of one or several polyols and polybasic acids (or anhydrides). Polyester plastics are widely used in the preparation of various textiles, packaging materials, mechanical parts, agricultural films, biological Medicines and other products. [0003] The molecular backbone of polyester is mainly composed of carbon and hydrogen combustible elements. It is a flammable material that will melt when exposed to fire, releasing a large amount of heat and producing harmful smoke particles. The heat and smoke released by polyester combustion will endanger life and pollute the environment. This defect greatly limits the application fields of polye...
