Problems solved by technology

The addition of surfactant antistatic agents is mainly to form a conductive continuous film on the surface of the material, endow the surface of the product with a certain hygroscopicity and ionic film, thereby reducing the surface resistivity and improving the antistatic performance. Processing and other advantages, but there are also disadvantages such as being easily affected by environmental humidity and short timeliness; while adding conductive fillers is to use the conductive fillers to contact each other to form a network chain, and free electrons can move on the network chain to form conduction. For antistatic purposes, this method has the advantages of long antistatic timeliness and is not easy to migrate, but this method requires a certain amount of conductive filler to have antistatic effect, and it is easy to affect the original physical properties of the material

Abstract

The invention discloses a halloysite nanotube-loaded surfactant / conductive polypyrrole composite antistatic agent, and a preparation method and an application thereof. Compared with the prior art, thepreparation method has the following advantages: a halloysite nanotube with a special hollow tubular structure and multiple layers of tube wall gaps are used as a carrier, molecules of a surfactant type antistatic agent are packaged in the tube cavity of the halloysite nanotube, polypyrrole is adopted for surface coating through a polymerization reaction, and the special tubular structure of thehalloysite nanotube is utilized to make the surfactant type antistatic agent adsorbed in the tube cavity be slowly released and orderly migrated to the surface of the material, so the timeliness and durability of the antistatic effect are effectively improved; and the halloysite nanotube is used as a template, the surface of the halloysite nanotube is coated with a layer of a conductive polypyrrole material through the polymerization reaction to form a nanotube material with conductivity and form a conductive network in the nanotube material, so the antistatic purpose is achieved. The novel long-acting composite antistatic agent with double effects is prepared and is applied to an antistatic plastic film, and the preparation method has the advantages of simplicity, convenience in operation, easiness in industrial production and the like.

Description

technical field [0001] The invention relates to a polymer material, more specifically to a halloysite nanotube-loaded surfactant / conductive polypyrrole composite antistatic agent and its preparation method and application. Background technique [0002] Generally, plastics are electrically insulating, and static electricity is easy to accumulate during production and use, and it is not easy to eliminate. Sticking tends to occur during the production of plastic films due to electrostatic attraction. In the process of packaging and use, it is easy to absorb dust and affect the appearance. In addition, static electricity can also cause distortion of precision instruments, scrapping and destruction of electronic components, and even cause fires, explosions, electric shocks and other accidents. In order to prevent plastics from generating static electricity, antistatic agents are generally added to accelerate the leakage of static charges to achieve the purpose of antistatic. ...
