Problems solved by technology

Since PC is easy to generate static electricity accumulation during production and use, it will cause electrostatic dust collection, electrostatic discharge and other adverse phenomena. The index is about 21% to 24%, and it can self-extinguish when it is away from the fire. The commercialized PCs on the market are evaluated according to the American UL94 standard for flame retardancy, and basically meet the requirements of V-2 grades, but it is difficult to meet the requirements of certain application fields. Therefore, it is necessary to carry out antistatic and flame retardant modification of PC to broaden its application range and meet market demand.

Abstract

The invention discloses a permanent antistatic flame-retardant modified PC composite material which comprises the following components by mass percent: 70-90% of PC resin, 1-3% of antistatic agent, 10-15% of fire retardant, 0.1-1% of anti-drip agent, 2-6% of compatilizer, 0.1-0.5% of complex antioxidant and 0.1-2% of lubricant. Compared with the prior art, the prepared permanent antistatic flame-retardant modified PC composite material has favorable flame retardant property and permanent antistatic property, the flame retardant level can be up to V-0 level, the comprehensive properties such as tensile strength and notch impact strength are excellent and the PC is ensured to be safely applied under the environmental conditions with high requirements for flame retardant property and antistatic property; and the permanent antistatic flame-retardant modified PC composite material is simple in preparation process, low in cost and preferably suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a permanent antistatic flame-retardant modified PC composite material. Background technique [0002] Polycarbonate (PC) is an engineering plastic with excellent comprehensive properties. Its impact resistance ranks first among thermoplastics. It has good dimensional stability and high heat distortion temperature (130°C~140°C). All excellent. It has been widely used in industries such as automobiles, electronics, home appliances, and construction. Since PC is easy to generate static electricity accumulation during production and use, it will cause electrostatic dust collection, electrostatic discharge and other adverse phenomena. The index is about 21% to 24%, and it can self-extinguish when it is away from the fire. The commercialized PCs on the market are evaluated according to the American UL94 standard for flame retardancy, and basically meet the requirements of V-...
