Example Embodiment

[0021] The weight percentage formula of the modified polypropylene composite material of Example 1 is: copolymer polypropylene 65%, polyolefin elastomer 6%, maleic anhydride grafted polypropylene 6%, γ-methacryloxypropyl trimethyl 0.5% of oxysilane, 10% of ammonium polyphosphate, 5% of melamine, 5% of pentaerythritol, 1% of organic montmorillonite, 0.5% of light stabilizer with CAS No. 82451-48-7, and 1% of stearic acid. The raw materials are mixed, stirred, extruded by a twin-screw extruder, cooled and pelletized to obtain the modified polypropylene composite material pellets of Example 1.

Example Embodiment

[0022] The weight percentage formula of the modified polypropylene composite material of Example 2 is: copolymer polypropylene 60%, polyolefin elastomer 4%, maleic anhydride grafted polypropylene 5%, γ-methacryloxypropyl trimethyl 0.3% of oxysilane, 14% of ammonium polyphosphate, 7.5% of melamine, 6.5% of pentaerythritol, 1.3% of organic montmorillonite, 0.2% of light stabilizer with CAS No. 82451-48-7, and 1.2% of stearic acid. The raw materials are mixed, stirred, extruded by a twin-screw extruder and then cooled and pelletized to obtain the modified polypropylene composite material pellets of Example 2.

Example Embodiment

[0023] The weight percentage formula of the modified polypropylene composite material of Example 3 is: copolymer polypropylene 70%, polyolefin elastomer 8%, maleic anhydride grafted polypropylene 8%, γ-methacryloxypropyl trimethyl 1.0% of oxysilane, 4.5% of ammonium polyphosphate, 2.7% of melamine, 2.3% of pentaerythritol, 0.3% of organic montmorillonite, 1.5% of light stabilizer with CAS number 82451-48-7, and 1.7% of stearic acid. The raw materials are mixed, stirred, extruded by a twin-screw extruder, cooled and pelletized to obtain the modified polypropylene composite material pellets of Example 3.

Abstract

The invention discloses a modified polypropylene composite material which comprises the following components in percentage by weight: 60-80% of polypropylene copolymer, 2-10% of toughener, 1-10% of maleic anhydride grafted polypropylene, 0.1-2% of coupling agent, 5-30% of halogen-free flame retardant, 0.2-2% of photostabilizer and 1-2% of stearic acid. The modified polypropylene composite material has the advantages of favorable weather resistance and long service life; the 3000-hour color difference is less than 1, and thus, the modified polypropylene composite material satisfies the requirement of no color fading after outdoor use for 8-10 years; the flame retardancy is favorable, the flame-retardant grade reaches V0 Grade, and the environmental protection property satisfies the RoHS standard requirement; and besides, the modified polypropylene composite material has excellent toughness, rigidity and scratch resistance. The modified polypropylene composite material can be used for blow molding, is suitable for producing various automobile parts, electric appliance parts and the like, and is especially suitable for producing outdoor bleacher chairs.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic polymer materials, and in particular relates to a modified polypropylene composite material. Background technique [0002] Polypropylene is widely used in automobiles, home appliances, textiles, construction and other industries due to its excellent mechanical properties, good electrical insulation, chemical resistance, low density and light weight. However, the oxygen index of polypropylene is low, only 17.14. It is easy to burn, and the heat of combustion is large, which will produce a large amount of molten droplets and smoke, which will have an adverse impact on the ecological environment, and it is easy to spread flames. In recent years, the fires caused by this Accidents occur frequently, causing huge damage to people's lives and property safety. Therefore, flame retardancy is also a requirement that polypropylene materials need to meet. At present, countries all over the world have ...
