Problems solved by technology

Polycarbonate has high toughness, high notched impact strength of cantilever beam, and high heat distortion temperature, but poor fluidity, difficult molding, products are sensitive to notch, prone to stress cracking, and not resistant to solvents
In order to make polycarbonate materials suitable for industrial applications, blending or copolymerization is often used in the prior art, but the inventors have found that the existing polycarbonate compositions enhanced by blending or copolymerization after a period of use become brittle, the structural strength is greatly reduced, and it is also very prone to mildew, which makes the appearance worse. Obviously, there is a need for further improvement in the prior art

[0014]

[0015] manual

[0016]

[0017] A weather-resistant, mildew-proof, and anti-bacterial polycarbonate composition according to each embodiment of the present invention is prepared by extruding and granulating after mixing the components uniformly to obtain a cold-resistant, mildew-proof, and anti-bacterial polycarbonate resin polymer. In the above examples and comparative examples, a high-speed mixer was used for mixing, and a 75L twin-screw extruder was used for extrusion with a rotation speed of 450r / min. The te...

Abstract

The invention provides a weather-proof mildew-resistant antibacterial polycarbonate composition. The composition is characterized by comprising, by weight, 90 parts of polycarbonate (PC), 1 to 20 parts of a flexibilizer, 1 to 20 parts of a cold-resistant agent, 1 to 10 parts of a fire retardant, 0.1 to 5 parts of a mildew-resistant antibacterial agent and 0.1 to 5 parts of an anti-ageing agent. Compared with the prior art, the invention has the following advantage: weather-proof, mildew-resistant and antibacterial properties of the polycarbonate composition are improved.

Description

technical field [0001] The invention relates to a weather-resistant, mildew-proof and anti-bacterial polycarbonate composition, which belongs to the field of polymer composite materials. Background technique [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. It is a linear carbonate polyester. The carbonic acid groups in the molecule are arranged alternately with other groups. Polycarbonate is almost colorless Glassy amorphous polymer with good optical properties. Polycarbonate has high toughness, high Izod notched impact strength, and high heat distortion temperature, but it has poor fluidity, difficult molding, and products are sensitive to notches, prone to stress cracking, and not resistant to solvents. In order to make polycarbonate materials suitable for industrial applications, blending or copolymerization is often used in the prior art, but the inventors have found that the existing polycarbonat...
