Abstract

The invention discloses a polycarbonate composition. The polycarbonate composition is prepared from, by weight, 1-99 parts of polycarbonate, 0.2-1 part of sulfonate flame retardant, 0.02-0.7 part of synergistic flame retardant and 0.3-1 part of siloxane. Accordingly, polycarbonate with a specific melt index, the sulfonate flame retardant with certain content, the synergistic flame retardant and the siloxane are added in the polycarbonate composition formula, the polycarbonate composition with the specific melt index is obtained through preparation, and the polycarbonate composition still has the good flame retardant property, good rigid-tough property and thermal stability and forming appearance on the condition that the flame retardant thickness of the thin film is 0.40 mm.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a polycarbonate composition and its preparation method and application. Background technique [0002] Polycarbonate (PC) has comprehensive and balanced mechanical properties, dimensional stability and heat resistance, especially known for its excellent impact strength and creep resistance. The visible light transmittance of PC resin is more than 90%, the thermal decomposition temperature is high, and it has excellent electrical insulation. Polycarbonate insulating films for electrical and electronic applications are widely used. [0003] The polycarbonate insulating film for electronic and electrical applications, whose thickness level is less than 0.5mm, can be divided into non-flame retardant and flame retardant types. Flame retardant insulating films are the application development trend. As electronic component materials, thin-walled materials For the developme...
