Abstract

The invention provides a high-whiteness and high-toughness PC composition and a preparing method thereof. The high-whiteness and high-toughness PC composition is prepared from, by weight, 50-85 partsof PC resin, 10-35 parts of glass fibers, 1-10 parts of a toughening agent, 2-8 parts of titanium dioxide, 0.2-0.6 part of an antioxidant and 0.1-0.5 part of a lubricating agent. Compared with the prior art, the high-whiteness and high-toughness PC composition and the preparing method thereof have the advantages that as the reinforced PC adopts special-treatment titanium dioxide, specific-thickness coating treatment and the silicon content, friction between the titanium dioxide and the glass fibers in an extruding machine is greatly reduced, the covering power of the titanium dioxide is kept,and the final material toughness is also improved. Under the same amount of the titanium dioxide, the whiteness of the reinforced PC can reach 97 or above, the impact strength can reach 30 KJ / m<2>, the toughness and the whiteness of the reinforced PC are greatly improved, and the application requirements of the high-whiteness and high-toughness PC composition in some electric-appliance-shell fields are met.

Description

technical field [0001] The invention relates to the field of polymer material modification, in particular to a PC composition with high whiteness and high toughness and a preparation method thereof. Background technique [0002] Polycarbonate (PC) has high light transmittance, high toughness, and high heat resistance. It is widely used in the field of electronic appliances. Reinforced PC greatly improves the rigidity and dimensional stability of the material, and is suitable for 3C and home appliances. [0003] Glass fiber has high tensile strength and good heat resistance, and it has no effect on the strength when the temperature reaches 300°C. It has excellent electrical insulation and is an excellent electrical insulating material. However, it is brittle and has poor wear resistance. When preparing high-whiteness reinforced PC, due to the high Mohs hardness of the commonly used white pigment titanium dioxide, it will cause severe friction with glass fiber in the twin-sc...
