Abstract

The invention discloses a polycarbonate composition. The polycarbonate composition comprises, by weight, 86-99.5 parts of polycarbonate, 0.2-0.7 part of total-fluorine substituted polyolefin and 0.3-13.8 parts of flame retardant. The sum of the weights of the polycarbonate, the total-fluorine substituted polyolefin and the flame retardants is 100 parts. The polycarbonate composition has the advantages that specific quantities of the total-fluorine substituted polyolefin, total-fluorine substituted alkyl acid and derivatives of the total-fluorine substituted alkyl acid are selectively added into the polycarbonate composition in a formula, the total-fluorine substituted alkyl acid and the derivatives are based on the polycarbonate composition, the total weight of the total-fluorine substituted alkyl acid and the derivatives is 5ppm-100ppm, and accordingly, the hydrolysis stability, the abrasion resistance and the flame retardancy of the polycarbonate composition can be obviously improved; the polycarbonate composition is particularly applicable to the field of electronic and electrical appliances.

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 is a tough thermoplastic resin, the second largest engineering plastic after polyamide in output. Polycarbonate is heat-resistant, impact-resistant, and has good mechanical properties at normal operating temperatures. It is widely used in automobiles , electronics, electrical appliances, construction, office equipment, packaging and other fields. [0003] However, due to the high requirements for flame retardancy of materials in electronics, electrical appliances, construction, and office equipment, polycarbonate must be treated with flame retardancy. In addition, polycarbonate has high hygroscopicity, and it is easy to produce bubbles and silver streaks during processing. The product is prone to residual internal stress and is highly sensitive to notc...
