Abstract

The invention provides a preparation method for an antistatic agent based on polyhydroxyl, gutter oil and quaternary ammonium salt. The preparation method comprises the steps that the gutter oil is heated and filtered to remove insoluble matter in the gutter oil, filtrate is added into a first reaction vessel, a sulfuric acid solution is added, reacting is performed, standing is performed for liquid separation, and an oil phase is washed with water with the same volume as the oil phase for three times to obtain a product A; the product A is added into a second reaction vessel, then epoxy chloropropane is added, reacting is performed, the redundant epoxy chloropropane is removed after reacting is completed, the mixture is placed in a vacuum drying oven to be dried, and a product B is obtained; the product B is added into a third reaction vessel, dialkyl ethanol amine is added, then reaction solvent is added, the redundant reaction solvent is removed after reacting is completed, residues are recrystallized with acetone, and the antistatic agent based on the polyhydroxyl, the gutter oil and the quaternary ammonium salt is obtained. The molecules of the antistatic agent contain the quaternary ammonium salt and the polyhydroxyl structure, so that forming of a water adsorption layer on the surface of a material is better facilitated, and the significant antistatic effect is further achieved.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of waste oil, in particular to a preparation method of an antistatic agent based on polyhydroxy waste oil quaternary ammonium salt. Background technique [0002] Any object has its own static charge. The accumulation of static charge will affect or even endanger life or industrial production. The chemical that guides or eliminates the accumulated harmful charge so that it does not cause inconvenience or harm to production or life is called antistatic. agent. Quaternary ammonium cationic surfactants are an important class of antistatic agents. When the quaternary ammonium salt is used to dissolve the impregnated material, its long-chain hydrophobic groups bond to the surface of the hydrophobic material, and the hydrophilic groups extend to the air, and the air is aligned on the interface of the material, forming a water adsorption layer on the surface of the material , which als...
