Abstract

The present invention discloses a PC / PTT alloy material of enhanced antistatic property, which comprises the following components in mass percentage: 40% to 60% of PC, 20% to 30% of PTT, 2% to 4% of E-MA-GMA, 8% to 15% of glass fibers, 5% to 8% of ACR, 1% to 3% of antistatic agent, 0.5% to 2% of light stabilizer, 0.1% to 0.5% of antioxidant, and 0.1% to 1% of lubricant. The antistatic agent is at least one selected from fatty acid polyglycol ester, polyoxyethylene lauryl ether, polyethylene oxide, polyether ester amide, polyether urethane imide, glycerol monostearate, alkyl sodium sulfonate, and nano-scale antimony-doped tin oxide. According to the invention, the original advantages of PC and PTT are integrated, and the PC / PTT alloy material is excellent in anti-static property. The surface resistance of the PC / PTT alloy material is up to 108 to 10 omega. Meanwhile, the PC / PTT alloy material is high in mechanical strength, good in impact toughness, excellent in chemical resistance, low in cost and wide in adaptability.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PC / PTT alloy material with enhanced antistatic properties. Background technique [0002] Polycarbonate (PC) / polytrimethylene terephthalate (PTT) alloy has the outstanding impact performance and heat resistance of PC and the excellent physical and chemical properties of PTT, and can be used as a new type of alloy material for automobiles and household appliances , electronics, sporting goods and other fields. However, PC is an amorphous polymer, PTT is a semi-crystalline polymer, and PC / PTT is a typical blend system of amorphous and crystalline polymers. Therefore, PC / PTT blend alloys have poor toughness, unstable mechanical properties, and antistatic properties. The problem of insufficiency. In order to obtain a high-performance PC / PTT alloy, it is often necessary to add a third component to the alloy material to improve its performance and application effect, and t...
