Abstract

The invention discloses a PC composite material and a preparation method and application thereof. The PC composite material comprises the following components in parts by weight: 100 parts of polycarbonate; 1 to 5 parts of polyethylene-butyl acrylate grafted glycidyl acrylate; 2-6 parts of a toughening agent; the flexibilizer is selected from any one or more of core-shell structure polymers which take methyl methacrylate or polystyrene acrylonitrile as a shell and take acrylate or acrylate grafted organic silicon as a core. The polyethylene-butyl acrylate grafted glycidyl acrylate is added into the polycarbonate material, and meanwhile, the core-shell structure toughening agent with specific components is added, so that the bonding performance of the material and cloth can be remarkably improved, and meanwhile, good toughness is kept; the direct bonding of the material and the cloth is realized, and the bonding strength is high. The application range of the polycarbonate material is further widened, and the polycarbonate material can be used for preparing fabric electronic products such as fabric mobile phone shells and fabric loudspeaker box shells.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a PC composite material and its preparation method and application. Background technique [0002] Polycarbonate (PC) is an engineering resin with excellent comprehensive performance. It has been widely used in the fields of automobile industry, electrical and electronic, and office equipment for its outstanding impact strength, dimensional stability, transparency, and weather resistance. Applications. However, polycarbonate materials have low hardness and poor wear resistance, so when they are used in some wear-prone scenes (such as consumer electronics product shells), special surface treatment (such as spraying treatment) is usually required to prevent the surface of the product from being easily damaged during use. Scratches and damages, but because the polycarbonate molecular chain is relatively rigid, the internal stress after molding is relatively large, and t...
