Abstract

The invention relates to the technical field of a high polymer material antistatic agent, and particularly relates to a quaternary ammonium salt hyperbranched antistatic agent. Propargyl alcohol reacts with succinic anhydride so as to obtain a modified monomer R1, the R1 reacts with 3-(dimethylamino)-1-propanethiol so as to obtain a modified monomer R2, the R2 reacts with a hydroxyl-terminated hyperbranched polymer so as to obtain a dimethyl amine-terminated hyperbranched structure, and then the dimethyl amine-terminated hyperbranched structure reacts with alkyl chloride so as to obtain the quaternary ammonium salt hyperbranched antistatic agent. The molecules of the antistatic agent contain more effective active groups, the utilization rate of the molecules is relatively high, the surface water absorbability of the antistatic agent in a substrate is relatively strong, and correspondingly the antistatic agent has a relatively good antistatic effect; the antistatic agent has relatively good compatibility with a medium and very good dispersibility.

Description

technical field [0001] The invention relates to the technical field of polymer material antistatic agents, in particular to a quaternary ammonium salt hyperbranched antistatic agent, and also to a preparation method of the quaternary ammonium salt hyperbranched antistatic agent. Background technique [0002] With the continuous development of polymer materials, more and more polymer products are used. In addition to the characteristics of lighter weight compared with inorganic materials, polymers also have better physical properties such as strength. However, since ordinary polymer materials are good insulating materials, the surface is prone to generate static electricity due to friction. If the static electricity is not discharged in time, a large amount of static electricity will generate sparks, which will cause different hazards in different fields. For example, static electricity generated on the surface of plastics may cause problems such as production failure, sparks...
