Cold-resistant mouldproof antibacterial polycarbonate composition

Abstract

The invention provides a cold-resistant mouldproof antibacterial polycarbonate composition which comprises the following components in parts by weight: 85 parts of polycarbonate (PC), 1-20 parts of a flexibilizer, 1-20 parts of a cold resistant, 1-10 parts of a flame retardant, 0.1-5 parts of a mouldproof antibacterial agent and 0.1-5 parts of an anti-aging agent. Compared with the prior art, the cold resistance and the mouldproof antibacterial performance of the polycarbonate composition are enhanced.

Description

technical field [0001] The invention relates to a cold-resistant, mildew-proof and antibacterial 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 polycarbonate co...

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 , is very prone to mildew, which makes the appearance worse and the structural strength is also reduced. In addition, the polycarbonate composition of the prior art also needs to be improved in terms of cold resistance, otherwise it is difficult to be suitable for long-term use in low temperature environments
