Abstract

The invention belongs to polymer composite materials and the technical field of preparation methods of the polymer composite materials, particularly relates to an antistatic engineering plastic formed by carbon nano tube and PET (polyethylene terephthalate), and further relates to a preparation method thereof. The antistatic PET engineering plastic comprises the following components in parts by weight: 90 to 95 parts of PET, 2.0 to 7.0 parts of carbon nano tubes A, 1.0 to 5.0 parts of carbon nano tubes B, 0.1 to 1 part of coupling agent, 0.1 to 1 part of dispersant, and 0.02 to 0.1 part of antioxygen. The carbon nano tubes A are carbon nano tubes with particle size of 50 to 100 nm and the length of 5 to 20 Mum; the carbon nano tubes B are carbon nano tubes with the particle size of 10 to 30 nm and the length of 5 to 15 Mum; and the intrinsic viscosity number of the PET is higher than 0.9.

Description

[0001] technical field [0002] The invention belongs to the technical field of a polymer composite material and its preparation method, and in particular relates to an antistatic engineering plastic formed of carbon nanotubes and polyethylene terephthalate (PET), and also relates to a preparation method thereof. Background technique [0003] Polyethylene terephthalate (PET) is the most important polyester material at present. It is cheap, has excellent wear resistance, heat resistance, chemical resistance and high mechanical strength, and is mainly used in production Fiber, film and hollow container etc. However, PET also has disadvantages in the use of engineering plastics. Its crystallization speed is too slow at commonly used processing temperatures, resulting in prolonged molding cycles, and products are prone to sticking to the mold and warping; in addition, PET has poor toughness and impact resistance. These disadvantages limit the use of PET. On the other hand, be...
