Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a modified polypropylene composite material and its application. Background technique [0002] Polycarbonate or its alloys are usually used as switch panel materials, mainly based on the high heat resistance, high strength, and high toughness of polycarbonate, and the flame retardancy of pure polycarbonate resin can reach UL94-V2 level, which can It does not burn at 850°C over a glow wire. Polycarbonate is colorless and transparent, has good dimensional stability, is easy to color, is rigid and tough, has high impact strength, heat and cold resistance, creep resistance, electrical insulation, and flame retardancy. All have good mechanical properties, but polycarbonate has poor solvent resistance and fatigue resistance, is prone to stress cracking, is sensitive to notches, and has a high price. Contents of the invention [0003] Aiming at the defects of the prior art, ...
