Abstract

The invention provides a preparation method for a permanently-antistatic ionic-liquid high polymer master batch. The preparation method comprises the following steps: 1) adding high polymer monomer A, acid anhydride B and initiator C into a reaction vessel, introducing nitrogen for protection and carrying out a reaction at 65 to 250 DEG C for 3 to 8 h so as to obtain a segmented copolymer D; 2) adding 10 to 65 parts by weight of ionic liquid into 100 parts by weight of the segmented copolymer D, introducing nitrogen for protection and carrying out stirring at 65 to 250 DEG C for 1 to 5 h so as to obtain a segmented copolymer E; and 3) adding 70 to 99 parts by weight of the segmented copolymer E grafted by ionic liquid, 0.05 to 0.2 part by weight of anti-oxidant, 1 to 3 parts by weight of hydroxy silicone oil, 0 to 50 parts by weight of a filling material, 3 to 10 parts by weight of heat stabilizer and 3 to 5 parts by weight of silicone oligomer into an internal mixer, carrying out heating and uniform mixing under stirring and then carrying out extrusion and granulation so as to obtain the permanently-antistatic ionic-liquid high polymer master batch. The invention further provides application of the high polymer master batch in high-molecular materials. The permanently-antistatic ionic-liquid high polymer master batch has permanent antistatic performance and good compatibility with high polymer.

Description

technical field [0001] The invention relates to an antistatic high polymer masterbatch, in particular to a preparation method of a permanent antistatic ionic liquid high polymer masterbatch and its application in polymer materials. Background technique [0002] Static charge is generally generated by the contact friction between two materials with different charge dissipation capabilities. The material that loses electrons has a positive charge, and the material that has gained electrons has a negative charge. The electrical properties of materials mainly include the following aspects: dielectric constant (materials with lower dielectric constants are prone to static electricity), resistivity (materials with lower resistivity are easier to dissipate static electricity). [0003] Polymer materials generally have high surface resistivity (10 10 -10 15 Ω) and low dielectric constant, so it is easy to generate static electricity and reach an electric field strength of 15000V / c...
