Abstract

The invention provides modified anti-static PC plastic. A preparation method of the modified anti-static PC plastic comprises the following steps: step a, preparing anti-static particles; and step b, adding 2-8 parts by weight of antistatic particles and 100 parts by weight of a PC material into a twin-screw extruder for melt extrusion granulation at the extrusion temperature of 180-210 DEG C to obtain the modified PC plastic, the antistatic particles comprise the following components in parts by weight: 16-20 parts of polyether ester amide, 3-8 parts of a methacryloyloxyethyl trimethyl ammonium chloride polymer, 2-5 parts of maleic anhydride, 8-15 parts of a PC material and 5-12 parts of an ABS material. Harm of static electricity to a human body can be reduced, and static electricity generated when cargoes are carried and unloaded is reduced. In the petrochemical industry, the risks of combustion, explosion and the like caused by static electricity can be prevented. In the industries of electronics, instruments and the like, the problem that electronic components are damaged or aged due to static electricity can be prevented.

Description

technical field [0001] The invention belongs to the technical field of plastic modification, in particular to a modified antistatic PC plastic. Background technique [0002] There are many synthetic plastic materials used in daily life. Plastics are all polymer materials, and the volume resistance is greater than 10. 12 Ω or more. Thus, good insulating properties are imparted to the plastic material. And because of this reason, it is very easy to generate static electricity. Static electricity can help our life in some cases, but it can also cause many problems, such as causing failure or malfunction of electronic equipment, causing electromagnetic interference, and breaking down integrated circuits. and precision electronic components, or promote the aging of components. Static electricity may even cause explosions and fires in production sites with many flammable and explosive products or dust and oil mist. In the electronic and electrical industry, due to electrostatic ...
