Abstract

The invention relates to a polycarbonate composition, in particular to a low-melting-point scratch-resistant polycarbonate composition and a preparing method of the low-melting-point scratch-resistant polycarbonate composition. The low-melting-point scratch-resistant polycarbonate composition comprises the following ingredients in parts by weight: 70 to 90 parts of polycarbonate, 10 to 25 parts of polylactic acid, 12 to 20 parts of polytrimethylene terephthalate, 5 to 15 parts of flame retardants, 5 to 15 parts of erucyl amide, 3 to 8 parts of glass fiber, 3 to 10 parts of organic silicon toughening agents, 0.1 to 5 parts of polyethylene wax and 0.2 to 0.8 part of antioxidants. The polycarbonate composition provided by the invention has the advantages that the processing temperature of products extruded through an extruding machine is lowered in the subsequent processing process, so the cost of the subsequent processing is reduced, and the energy source waste is reduced.

Description

technical field [0001] The invention relates to a polycarbonate composition, in particular to a low melting point scratch-resistant polycarbonate composition and a preparation method thereof. Background technique [0002] Polycarbonate resin (Polycarbonate, referred to as PC) has high impact resistance and heat resistance and is the only one with transparency in general-purpose engineering plastics, so it has the title of "transparent steel". With the advantages of toughness and dimensional stability, it can be widely used in optical lenses, optical disc substrates, electrical appliances, building materials, automobiles and other fields. In recent years, with the expansion of application fields and production scale of polycarbonate resin, the requirements for processing characteristics are getting higher and higher. Therefore, the industry still expects to further improve its physical properties and processing properties. Polycarbonate (PC) has excellent mechanical properti...
