Problems solved by technology

However, due to the large specific surface area and ultra-high aspect ratio of carbon nanotubes, and the strong van der Waals force between unmodified carbon nanotubes, carbon nanotubes are entangled with each other and difficult to separate, forming clusters or bundles. shape aggregates, thus showing a poor dispersion effect, which restricts the full play of its performance

Abstract

The invention discloses a flame-retarding anti-static polyester and a preparation method thereof. The preparation method comprises the following steps: through selecting carbon black with a specific DBP value, in a specific proportion, compounding with carbon nano tubes and graphene, forming a nano composite structure with good electrical conductivity; and after enabling the nano composite structure to perform in-situ copolymerization and melt spinning with terephthalic acid and ethylene glycol, preparing composite polyester fibers with both flame retardance and anti-static property. The preparation method is capable of, in the case of only adding trace carbon nano tubes (0.12%), trace graphene (0.2%) and little carbon black (1.2%), remarkably improving electrical conductivity and flame retardance of a traditional polyester, in addition, a product is good in spinnability, stable in performance, low in cost, and small in industrialization difficulty, and has a remarkable practical value.

Description

technical field [0001] The invention belongs to the field of fibers, and in particular relates to a flame-retardant and antistatic polyester and a preparation method thereof. Background technique [0002] In daily life, when two objects of different materials are in contact and then separated, static electricity can be generated. This is because one object loses a certain amount of charge and becomes positively charged, while the other object gains charge and becomes negatively charged. These charges are difficult to neutralize easily. It will gradually accumulate to form static electricity. The main ways to form static electricity in daily life are friction, induction and conduction. Static electricity itself is a very common phenomenon, but when the static electricity is accumulated and released violently, it is very easy to cause circuit breakdown, information interference, fire, electric shock and other phenomena, which can cause discomfort to the human body, increase d...
