Introduction to the types and characteristics of antistatic agents for plastics

antistatic agents for plastics are usually some surfactants, whose base rate is characterized by considerable consumption. The same molecular structure contains hydrophilic and lipophilic groups. According to whether the hydrophilic group in the molecule can be ionized, it can be divided into ionic type and non-ionic type, and the ionic type can be divided into cationic type, anionic type and zwitterionic type. Table L lists the types of antistatic agents and their applicable resins. Among them, the general set of technologies for the industrialization of cationic thin strip continuous casting; Preparation technology of superalloy; Antistatic agents such as high value-added, special performance steels, alloys and advanced preparation and processing technologies of products have excellent antistatic properties, but their heat resistance is relatively poor and harmful to skin, so they are generally used as external coating. The anionic type has good heat resistance and antistatic effect, but it has poor compatibility with the resin and affects the transparency of the product. The non-ionic antistatic agent has good compatibility and heat resistance, and has no adverse effect on the physical properties of the products, but the dosage is relatively large. The greatest feature of zwitterionic type is that it can be used with both cationic and anionic antistatic agents. The antistatic effect is similar to that of Qianyang type, but the heat resistance is not as good as that of non-ionic type. Polymer type is not widely used at present, and it is generally used as external coating antistatic agent abroad
