Antistatic additives are commonly used in the preparation of low molecular weight organic compounds or functional monomers. Common processes include esterification, etherification, sulfonation, and polycondensation.
Raw Material Preparation: Fatty alcohols, fatty acids, polyethers, or other hydrophilic monomers are selected as base raw materials, with strict control over moisture and impurities.
Reaction Operation: Esterification or etherification reactions are carried out at suitable temperatures (generally 120~200℃) and under catalytic conditions. The reaction time is controlled according to the target molecular weight.
Post-treatment: After the reaction, neutralization, dehydration, and purification are performed to remove unreacted raw materials and byproducts, ensuring product purity and stability.
Quality Control: Surface resistivity, volume resistivity, charge decay time, and thermal stability are measured to ensure product performance meets design requirements.
Features: Chemically synthesized products have controllable structures and stable properties, making them suitable for plastics, coatings, and fiber materials with strict requirements for antistatic effects and migration.
