Embodiment Construction
[0012] A kind of preparation method of antistatic agent of the present invention, comprises the steps:
[0013] (1) Take PPW-g-MAH and small molecule diethanolamine DEA that have been grafted with polypropylene wax and maleic anhydride and place them in a round bottom flask, add catalyst, then add xylene, electromagnetically stir under nitrogen protection, 150 °C Constant temperature reaction 2h;
[0014] (2) Cool the reaction solution to about 110°C and pour it into ethanol to obtain a white cotton flocculent precipitate. The product is soaked in ethanol for several times to remove free DEA, and filtered with a Buchner funnel, and the filter cake is placed in an oven at 80°C Medium drying to constant weight; the performance of PPW-g-DEA nonionic antistatic agent depends on the content of polar hydroxyl groups, the higher the content of hydroxyl groups, the better the performance of antistatic agent.
[0015] (3) The PPW-g-DEA synthesized by the above step (2) is mixed with P...

Abstract
The invention discloses a preparation method of an antistatic agent and belongs to the field of chemical industry. The preparation method is characterized by including following steps: taking and placing PPW-g-MAH and micromolecule diethanolamine after going through polypropylene wax and maleic anhydride grafting treatment in a round-bottom flask, and adding a catalyst; adding dimethylbenzene, electromagnetically stirring under protection of nitrogen, cooling reaction liquid, and pouring the reaction liquid into alcohol to obtain white flocculent precipitate; using alcohol to soak a product for many times to remove free DEA; using a Buchner funnel for suction-filtering, and disposing a filter cake in an oven for drying to constant weight; mixing the filter cake with PP master batch, placing a mixture in an open mill for mixing, and tableting through a vulcanizing machine to prepare a diaphragm. By improving the preparation method, MAH in PPW-g-MAH is utilized as a bridging agent to graft micromolecule DEA to prepare a PPW-g-DEA antistatic agent which has good antistatic performance; the preparation method is simple in process, easy to operate and wide in application prospect.
Description
technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a preparation method of an antistatic agent. Background technique [0002] With the rapid development of the economy, more and more new materials have been applied to our lives, bringing great convenience to people's lives. Among them, polypropylene has good heat resistance and chemical resistance. Non-toxic, non-toxic, easy to recycle and other characteristics and can be widely used. However, during its application, when there is friction, peeling or induction, it will lead to the accumulation of static charge on the surface of the product, and even when the static electricity causes corona discharge or spark discharge, it will cause fire or explosion, which will bring losses to people. harm. Contents of the invention [0003] The present invention aims to solve the above problems and provides a preparation method of an antistatic agent. [0004] A kind of prepa...
