Abstract

The invention discloses a PC (Poly Carbonate) / PA (Polyamide) 66 composition and a preparation method thereof. The PC / PA66 composition is prepared from the following raw materials in parts by weight: 65-90 parts of poly carbonate and 10-35 parts of polyamide 66, totaling 100 parts, as well as 0.1-3 parts of toluene diisocynate, 0.1-3 parts of 2, 2'-(1, 3-phenylene)-dioxazoline, 0.1-6 parts of styrene-maleic anhydride copolymer, 0.1-2 parts of anti-dropping agent, 0.1-1 part of hindered phenol antioxidant, 0.1-1 part of phosphite ester antioxidant and 0.1-1 part of lubricant. The PC / PA66 composition which is prepared through a reaction in-situ reaction capacity-increasing method and has good mechanical property, high flame retardance, chemical resistances and good processability can be applied to industries of automobiles, electronics and the like.

Description

technical field [0001] The invention relates to the field of materials, in particular to a PC / PA66 composition and a preparation method thereof. Background technique [0002] The rapid development of China's industry in recent years has continuously expanded the application of polycarbonate (PC), and its demand has also continued to increase. However, with the rapid advancement of science and technology and the continuous upgrading of industrial products, the requirements for material performance are becoming more and more stringent. Conventional polycarbonate can no longer meet the requirements of various types of products in terms of product performance, and PC has a melt viscosity. Large size, poor fluidity, easy hydrolysis at high temperature, poor solvent resistance, high sensitivity to notches, prone to swelling and stress cracking, and large friction coefficient, high melting temperature, high price of special grades, etc., which directly affect its further applicatio...
