Abstract

The invention relates to an antistatic polyethylene glycol terephthalate composite material. Glycol, terephthalic acid and nano antistatic agent-glycol sol are polymerized, the esterification reaction temperature is 200-290 DEG C, and the pressure is 0.1-0.5MPa; the low-vacuum polycondensation reaction temperature is 200-290 DEG C, the pressure is reduced from normal pressure to 1,000Pa; and the high-vacuum polycondensation reaction temperature is 250-300 DEG C, and the reaction vacuum degree is 100-50Pa. The nano antistatic agent-glycol sol is formed by nano carbon black, nano metal, nano metal compounds and glycol. A nano antistatic agent accounts for 0.1-10% of the weight of the polyethylene glycol terephthalate and accounts for 1-10% of the weight of the nano antistatic agent-glycol sol. The intrinsic viscosity of the material is 0.55-0.75dL/g, and the volume resistivity of a fiber is 108 ohms/cm-109 ohms/cm.

Description

Technical field: [0001] The invention relates to an antistatic polyethylene terephthalate composite material. Background technique: [0002] Polyester fiber is a hydrophobic high polymer with a regular structure, neither ionization nor free electrons; polyester fiber itself is an insulator with poor hygroscopicity, and it is difficult to dissipate the static electricity generated after contacting or rubbing with other objects. Then the polyester fiber is charged with static electricity. [0003] At present, there are two main ways to eliminate static electricity of polyester fiber. One is post-treatment technology, that is, electroplating on the surface of the fiber with metals such as copper and silver, or coating the surface of the fiber with a hygroscopic agent, and treating it with polyaniline or pyrrole solution. Polyester fabric. However, the antistatic effect is not long-lasting, it is not washable and wear-resistant, and it affects the hand feel. [0004] The othe...
