Abstract

The invention relates to an antistatic agent used for a plastic, and belongs to the technical field of high-molecular material modification methods. The antistatic agent provided by the invention hasthe following beneficial technical effects: a mixed ester is utilized to change interface properties of the plastic, compatibility between the plastic and the antistatic agent is increased, hydrogen peroxide oxidation is performed by using powder as a raw material, steam explosion is performed to destroy the internal structure, filter residues and ionic liquids are mixed, the mixed solution is dissolved to make cellulose and lignin of the powder dissolved, and the formed ionic liquid can continue to transfer electric charges on the surface of the plastic, thereby improving the antistatic effects, the cellulose and lignin of the formed ionic liquid are modified by utilizing acetic anhydride to increase bonding performance between the antistatic agent and the plastic, and the obtained composite solution and an active substance are mixed to improve hydrophilic properties of one end of the modified product; the antistatic agent can adsorb water molecules in the air to form a uniformly-distributed conductive solution on the surface of the material when being used to further increase the antistatic properties; and the antistatic agent solves the problem that a current antistatic agent has poor antistatic properties because of poor compatibility of the current antistatic agent and the plastics.

Description

Technical field [0001] The invention relates to an antistatic agent for plastics, and belongs to the technical field of polymer material modification methods. Background technique [0002] Antistatic agent is a general term for chemicals that can guide or eliminate accumulated harmful charges so that they do not cause inconvenience or harm to production and life. Current methods for polymer antistatic include adding conductive fillers, blending with conductive polymer materials, and adding antistatic agents. By adding an antistatic agent to the polymer, the resistivity of the material can be reduced and the static electricity phenomenon of the material can be eliminated. As a general-purpose plastic, polyvinyl chloride has a wide range of uses. Its outstanding advantages are flame retardancy, abrasion resistance, chemical corrosion resistance, and good gas and water vapor permeability at low pressure. Because of its low price and superior performance, it is widely used in the c...
