Problems solved by technology

[0004] Among them, although the first method can make the plastic have good electrical conductivity, it will inevitably cause changes in other properties of the plastic, such as mechanical properties, plasticizing properties, and transparency, which will be affected, thereby limiting its application.
Although the second method has excellent antistatic properties in a short period of time after the product is formed, the surfactant precipitated on the surface of the product will be lost through friction, washing, etc., so it is difficult to maintain performance for a long time, and its conductivity is heavily dependent on Due to factors such as air humidity, its conductivity will decrease when the air is dry
And, as we all know, when the air is dry, static electricity is easier to generate and discharge

Description

technical field [0001] The invention belongs to the field of antistatic, and in particular relates to a method for preparing an antistatic agent and a method for preparing antistatic plastics by using the antistatic agent. Background technique [0002] Plastic products are used in various molded products and films due to their excellent characteristics, but in actual use, due to friction, temperature, etc., the surface of plastic products will form static electricity, and plastic products are usually non-conductive. Therefore, dust, etc. will be adsorbed on the surface of the product, or electrical barriers will appear in the public, or electronic equipment will be damaged due to static electricity accumulation and discharge when used in electronic equipment. Therefore, how to prevent static electricity and quickly conduct static electricity has become a research hotspot. [0003] There are two anti-static methods commonly used in the past. One is to add conductive fillers ...
