Abstract

The invention relates to a corrosion-resistant low-VOC high-flame-retardance halogen-free engineering plastic and a preparation method thereof. The engineering plastic contains PX-220, PBT, PC, a flexibilizer and an antioxidant. by adding different doses of PX220 solid retardants into PBT / PC engineering plastic, the flame retardance of the engineering plastic is greatly improved, the corrosion resistance is very high, the odor level is very low, the total amount of organic volatile compounds is very low. The engineering plastic has very wide use in the aspects of automobile decoration, household appliances, electrons, electricity and sporting goods.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a corrosion-resistant, low-VOC, high-flame-retardant, halogen-free engineering plastic and a preparation method thereof. Background technique [0002] Since the beginning of the new century, various application fields of engineering plastics have put forward more and more stringent requirements for their flame retardancy, especially in the electronic information industry. Moreover, in recent years, the application industry of flame-retardant engineering plastics is also expanding, and the demand is increasing. [0003] Before 1986, flame-retardant engineering plastics were almost all brominated products, but since the early 1990s, based on the requirements of environmental protection and sustainable development, the call for non-halogenation of flame-retardant engineering plastics has become more and more serious. Fuel has been banned, especially the promulgation of...
