Abstract
The invention provides a glass fiber reinforced polycarbonate composition as well as a preparation method and application thereof. The composition is prepared from the following raw materials in partsby weight: 10-90 parts of polycarbonate, 10-90 parts of nylon 66, 1-50 parts of glass fibers, 0.5-20 parts of a reactive toughening agent, 0.5-20 parts of polyurethane, 0.001-5 parts of an antioxidant and 0.001-5 parts of a lubricant, wherein the diameter of the glass fiber is 8-15 microns; and the reactive toughening agent has a reactive group capable of reacting with both nylon 66 and polycarbonate, and D50 is greater than 100 nm. According to the glass fiber reinforced polycarbonate composition, through the synergistic effect of the reactive toughening agent and the polyurethane, the glassfiber reinforced polycarbonate alloy composition is endowed with a good matte effect, and the requirements of various processes for glossiness can be met; and meanwhile, relatively high processability and enough toughness are kept.
Description
