Abstract

The invention provides an anti-static material which comprises following components in percentage by weight: 25% of rosin varnish solid material, 50 to 67% of solvent, 7.5 to 23% of alcohol solvent and 0.5 to 2% of sodium polystyrenesulfonate solid material. The preparation method of the anti-static material is that sodium polystyrenesulfonate, alcohol solvent, solvent and rosin varnish are added in sequence, and stirred uniformly to obtain the anti-static material. The anti-static material has long anti-static effect without influence of environment temperature and humidity, is 5 times longer than common small molecule antistatic agent in service time, has stable surface resistance value (the lowest is 105 ohm), and can be utilized repeatedly in the electronic packaging industry, so that the production cost of enterprises is effectively reduced.

Description

[0001] technical field [0002] The invention relates to the field of chemical materials, in particular to a high molecular polymer antistatic material and a preparation method thereof. [0003] Background technique [0004] There are two methods of antistatic: one is to reduce or suppress its electrification; the other is to quickly leak the generated static electricity to reduce the accumulation of static electricity. Antistatic agent refers to a class of chemical substances that can inhibit the generation of static electricity and promote charge leakage to prevent or eliminate the accumulation of static electricity on the surface of polymer materials. There are many kinds of antistatic agents, which can be divided into anionic, cationic, amphoteric and nonionic antistatic agents according to whether their hydrophilic groups can be ionized and the nature of the charge after ionization. [0005] Anionic antistatic agents are mostly used as antistatic agents for chemical f...
