Abstract

The invention provides a low-temperature-resisting fireproof polypropylene material easy to shape. The low-temperature-resisting fireproof polypropylene material easy to shape is prepared from, by weight, 20-50 parts of ternary polymerization polypropylene, 20-50 parts of random copolymerization polypropylene, 5-30 parts of halogenated flame retardant, 5-30 parts of synergetic flame retardant, 25-40 parts of inorganic filler and 0.5-2 parts of nucleating agent. The obtained low-temperature-resisting fireproof polypropylene material easy to shape has good flame retardant performance, can still keep high performance in the low-temperature environment and is extremely good in shaping performance, and injection shaping is easier when the low-temperature-resisting fireproof polypropylene material easy to shape is applied to large products.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to an easy-to-shape low-temperature-resistant and fire-resistant polypropylene material. Background technique [0002] Polypropylene material is odorless, non-toxic and tasteless in line with national health standards. It has a low density and is the lightest of general-purpose plastics. It can be used without deformation for a long time at a temperature of 100 degrees, and has excellent electrical insulation properties and chemical stability. , hardly absorbs water, and has no effect in contact with most chemicals. Introduce other monomers into the polypropylene macromolecular chain; or cross-link through cross-linking agents; or improve through nucleating agents and foaming agents, thereby endowing polypropylene with higher mechanical properties. The modified polypropylene material has more superior chemical resistance, heat resistance and impact resistance, a...
