Modified polypropylene composite material and application thereof

The invention belongs to the technical field of polymer materials, and discloses a modified polypropylene composite material and an application thereof. The compound material is composed of following components in parts by weight: 50 to 70 parts of polypropylene, 10 to 20 parts of glass fiber, 12 to 15 parts of fire retardant, 3 to 5 parts of flame retardant synergist, 0 to 15 parts of flexibilizer, and 1.5 to 15 parts of auxiliary agent. The invention also provides an application of the polypropylene compound material mentioned above as an electrical panel. The modified polypropylene composite material is capable of being used as an electrical panel. The composite material has a high performance-cost ratio, a low price, an excellent processing property, a lower processing temperature and a good forming property, can fully meet the performance requirements of electrical panel material on mechanical strength, impact toughness, heat resistance, flame resistance, and insulating property, and does not need a drying treatment before processing.
