PC是分子主链中含有碳酸酯基的聚合物统称为聚碳酸酯,根据醋基结构可分为脂肪族、芳香族、脂肪族一芳香族等多种类型。目前商业化聚碳酸醋的基本结构为芳香族代。由于代是一种综合性能优良的非晶型热塑性树脂, 具有优异的电绝缘性、延伸性、尺寸稳定性及耐化学腐蚀性, 较高的耐热性和耐寒性还具有自熄、易增强、阻燃、无毒、卫生、能着色等优点,聚碳酸醋是增长速度快的通用工程塑料,目前聚碳酸醋的工业化装置基本上都是采用界面缩聚法工艺, 主要工艺是将双与溶液配制成双盐, 同时加人, 然后送人反应器内, 加人, 通进行化反应,反应完后将反应液送到缩聚反应器内, 加人和溶液, 进行缩聚反应.
(PC)--工程塑料的简介
工程塑料一般是指可以作为结构材料承受机械应力,能在较宽的温度范围和较为苛刻的化学及物理环境中使用的塑料材料。
工程塑料可分为通用工程塑料和特种工程塑料两大类。
通用工程塑料通常是指已大规模工业化生产的、应用范围较广的5种塑料,
即:
聚酰胺(尼龙,PA)
聚碳酸酯(聚碳,PC)
聚(POM)
聚酯(主要是PBT,PET)
聚醚(PPO,或变性PPE)。
PC Basic Description:
PC can be divided into aliphatic, alicyclic, aromatic and aliphatic aromatic groups. As one of the five engineering plastics, polycarbonate mainly refers to bisphenol a polycarbonate. PC is a kind of thermoplastic engineering plastics with excellent comprehensive properties. It can be used to manufacture parts such as machinery, automobile and precision instrument. It can also be used in electronic components and electric tool parts. However, the processing and molding requirements of PC are high, and it has no self-lubricating property, so it is not suitable for manufacturing products with metal inserts. Due to its non-toxic, good chemical resistance and excellent food hygiene performance, PC can be widely used in daily life. In particular, its tranrency is superior to other engineering plastics, so it is widely used in aviation glass, lamps, safety glass, office equipment, laser disc and other fields. It can be said that in all areas of the national economy, PC has been widely used, and is still expanding.
Polycarbonate (PC) has good mechanical properties and good creep resistance, which is better than that of phthalamide and paraformaldehyde. Especially, PC modified by glass fiber has better creep resistance, so it can bear higher load at higher temperature and ensure dimensional stability. The main shortcomings of polycarbonate mechanical properties are easy to produce stress cracking, poor fatigue resistance, high notch sensitivity, no wear resistance and so on. PC has good high and low temperature resistance, good heat resistance at 120 ℃, and hot deformation temperature of 130 ~ 140 ℃. At the same time, it has good cold resistance, brittleness temperature is - 100 ℃, long-term service temperature is - 70 ~ 120 ℃. Moreover, its thermal conductivity and specific heat capacity are not high, its linear expansion coefficient is small, its flame retardancy is good, and it has self extinguishing property. As a weak polar polymer, PC has better electrical insulation although its electrical insulation is not as good as that of polyolefins. Because of its high glass transition temperature and low hygroscopicity, it can maintain good electrical properties under wide temperature and humidity conditions
