Problems solved by technology

The flexural modulus of PC can reach more than 2400MPa, and the resin can be processed into large rigid products. The existing PC material is easy to fall off due to friction and lacks toughness, resulting in varying degrees of decline in antistatic performance of the PC material plate surface due to falling off. For this reason, a kind of antistatic, toughened grade PC and its preparation method are proposed

Abstract

The invention discloses antistatic toughened-grade PC and a preparation method thereof. Raw materials comprise, by mass, 7-10 parts of a curing agent, 30-90 parts of PC resin, 10-30 parts of plant fibers, 5-15 parts of an antioxidant, 10-15 parts of fatty acid diethanolamide, 3-7 parts of aminopropyl polydimethylsiloxane, 1-2 parts of epoxy chloropropane, 3-7 parts of an adhesive, 30-40 parts of magnesium oxide, 6-12 parts of a cosolvent and 7-11 parts of a toughening agent. The toughening agent, the adhesive and the magnesium oxide are added, so that the toughness of the PC material can be enhanced; due to the introduction of the fibers, the toughness of the material is improved; by adding the fatty acid diethanolamide, good wetting, dispersing, hard-resistant and anti-static properties are realized, particularly excellent thickening and foam stabilizing properties; the anti-static performance of a system can be remarkably improved when being compounded with a surfactant, and the situation that the anti-static performance is reduced to different degrees due to the fact that the surface of a PC material plate falls off due to lack of toughness and liable falling due to friction canbe avoided.

Description

technical field [0001] The invention relates to the technical field of PC materials, in particular to an antistatic and toughened grade PC and a preparation method thereof. Background technique [0002] Polycarbonate, referred to as PC, is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, due to the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonate, its application in engineering plastics is limited. PC is a linear carbonate polyester, and the carbonic acid group in the molecule is combined with other groups Alternately, these groups can be aromatic, aliphatic, or both. Bisphenol A type PC is the most important industrial product. PC is an almost colorless glassy amorphous polymer with good optics. PC high molecular weight resin has high toughness, the Izod notched impact strength is ...
