Problems solved by technology

However, antistatic, weather and anti-aging modification of PC often involves directly adding antistatic agents, light stabilizers, and antioxidants to PC. Due to the small amount of these additives, direct addition is not conducive to dispersion, and there are many processes. , difficult to operate, and even affect product quality, etc.

Embodiment 1

[0014] A PC antistatic and weather-resistant masterbatch, the components of which are proportioned by mass percentage: 30% PC resin, 30% alkylphenoxypropanesulfonate sodium anionic antistatic agent, benzotriazole ultraviolet absorber UV -327 30%, hindered phenolic antioxidant 1076 6%, TAS-2A 4%. Wherein, the PC resin is bisphenol A type aromatic polycarbonate.

[0015] Preparation method: Weigh each component according to the weight ratio, and add them into high-speed mixing respectively, and stir for 5-20 minutes to fully mix and evenly disperse, then discharge the material into a twin-screw extruder, heat at 210°C-260°C After melting, kneading, extruding, cooling and granulation, and packaging after drying, a PC antistatic and weather-resistant masterbatch of the present invention is obtained.

Embodiment 2

[0017] A PC antistatic and weatherproof masterbatch, its components are proportioned by mass percentage: PC resin 27%, alkylphenoxy propane sulfonate sodium anionic antistatic agent 40%, benzophenone ultraviolet absorber UV -531 25%, the compound of hindered phenolic antioxidant 1076 and phosphite antioxidant 168 5%, PETS 3%. Wherein, the PC resin is bisphenol A type aromatic polycarbonate.

[0018] Preparation method: Weigh each component according to the weight ratio, and add them into high-speed mixing respectively, and stir for 5-20 minutes to fully mix and evenly disperse, then discharge the material into a twin-screw extruder, heat at 210°C-260°C After melting, kneading, extruding, cooling and granulation, and packaging after drying, a PC antistatic and weather-resistant masterbatch of the present invention is obtained.

Abstract

The invention discloses a PC antistatic weather-resistant master batch. The PC antistatic weather-resistant master batch comprises the following components by weight percent: 15-50% of PC resin, 25-40% of antistatic agent, 25-40% of ultraviolet light absorber, 3-8% of antioxidant, and 2-5% of disperser. Compared with the prior art, the PC antistatic weather-resistant master batch has the beneficial effects of excellent antistatic property, weather resistance and antiaging performance by adding 2-5% of the master batch when applied to the PC production; besides the master batch is good in dispersity and convenient to use, and also has good using effect and industrial prospect.

Description

technical field [0001] The invention relates to a master batch, in particular to a PC antistatic and weather-resistant master batch. Background technique [0002] Polycarbonate (PC) is an increasingly widely used engineering plastic. Due to its high hardness, good dimensional stability, high impact strength, high thermal denaturation temperature, high modulus and high transparency, it is widely used in electronic appliances, Optics, medical instruments and automotive industry and many other fields. However, in the production, storage and use of PC, it is very easy to generate static electricity accumulation, resulting in electrostatic dust collection, electrostatic discharge and other adverse phenomena. In severe cases, sparks may be generated, causing fire or explosion; It will also gradually deteriorate and age. Therefore, it is generally necessary to modify PC in terms of antistatic, weather resistance and aging resistance to improve its performance. However, antistati...
