iHeir-D is a highly effective broad-spectrum fungicide. It is effective against bacteria, fungi, and algae. It has been widely used in antibacterial, anti-mildew, and anti-mold plastics, artificial leather, and coatings to prevent the degradation and discoloration of materials caused by bacteria, mildew, and long algae, as well as to prevent the growth of bacteria on the surface of coatings to prevent the transmission of diseases.
Phosphate ester salt antistatic agents with different structures differ greatly in performance. For example, monoalkyl phosphate ester salts have strong polarity and high water solubility, while dialkyl phosphate ester salts have good lubricity and are difficult to dissolve in water. They have an indispensable position in the textile industry and are mainly used as antistatic components of fiber finishes and fabric finishing agents. Used in other polymers, it shows more excellent effects than sulfate antistatic agents. Its representative structure includes dilauryl phosphate sodium salt, dilauryl phosphate triethanolamine salt, ft wax sasol phosphate sodium salt of lauryl alcohol ethylene oxide adduct, higher alcohol or alkylphenol ethylene oxide adduct Phosphate esters and their salts, etc.
High molecular weight anionic antistatic agent
High molecular weight anionic antistatic agents mainly include polyacrylate sodium salt, copolymer salt of maleic anhydride and other unsaturated monomers, and polystyrene sulfonic acid. This kind of antistatic agent has high molecular weight, good adhesion to polymer, high volatility resistance and water washing resistance, and can overcome the defects of poor antistatic durability of surfactants with strong hygroscopicity. Here, diisobutylene-maleic acid sodium salt is taken as an example to illustrate its synthetic route.
Diisobutylene-maleic acid disodium salt copolymer is a typical anionic durable antistatic agent. Its synthesis principle is based on maleic anhydride and diisobutylene as the basic raw materials. Firstly, it is initiated by azobisisobutyronitrile (A IBN). Copolymerization to obtain a copolymer with maleic anhydride segments, and finally to neutralize with NaOH to obtain the corresponding sodium salt product.
