Abstract

The invention relates to the technical field of flame-retarding materials and in particular relates to a flame-retarding and environment-friendly plastic material and a preparation method thereof. Theplastic material is prepared from the following raw materials in parts by weight: 10 to 15 parts of nano silicon dioxide, 3 to 7 parts of ammonium polyphosphate powder, 1 to 5 parts of aluminum hypophosphite, 4 to 9 parts of polylactic acid, 10 to 15 parts of antimony trioxide, 2 to 5 parts of 2,3-dichloropropyl ester, 3 to 7 parts of hydrated aluminum oxide, 6 to 10 parts of bromo-chloroalkyl phosphate diester, 1 to 4 parts of an ethylene-propylene-diene monomer and 0.5 to 2 parts of a dispersion lubricant. The flame-retarding and environment-friendly plastic material provided by the invention can be used for effectively overcoming the defects that a plastic material in the prior art has poor flame-retarding performance and the synergistic effect of the raw materials is poor.

Description

technical field [0001] The invention relates to the technical field of flame retardant materials, in particular to a flame retardant and environment-friendly plastic material and a preparation method thereof. Background technique [0002] Flame-retardant materials are materials that can inhibit or delay combustion but are not easy to burn. They are widely used in clothing, petroleum, chemical industry, metallurgy, shipbuilding, fire protection, national defense and other fields. Plastic is mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements. The finished product is solid, and it is a molten liquid during the manufacturing process. Therefore, it can be melted by heating, flow by pressure, and flow by cooling. It solidifies and forms various shapes. This large and varied group of materials is called plastics. Most of the existing plastic materials have the defects of poor flame retardancy and poor synergy between the constituent mater...
