A kind of preparation method of composite antistatic agent for PVC soles

Abstract

The invention discloses a PVC (Polyvinyl Chloride) sole composite type antistatic agent and a preparation method thereof. The PVC sole composite type antistatic agent comprises the following components in parts by weight: 100 parts of a polyvinyl alcohol solvent and 40-50 parts of a surface active agent. The preparation method of the PVC sole composite type antistatic agent comprises the following steps of: (1), based on weight parts, adding 40-50 parts of a surface active agent to 100 parts of polyvinyl alcohol solution, slightly heating up, filling the mixture to 100L stainless steel pressure reaction kettle for sealing the reaction kettle after the surface active agent is completely dissolved; (2), starting stirring, heating up to 170 DEG C-180 DEG C, wherein the pressure in the kettle is 8-9 atmospheric pressures, and reacting for 8-10 hours under the condition; and (3), cooling to the room temperature after the reaction is finished, opening the reaction kettle, and adjusting a pH value of the product to 7-8 using little acetic acid, thereby obtaining the product. The PVC sole composite type antistatic agent disclosed by the invention has the advantages of scientific formula, low production cost and simple preparation process, and is capable of strengthening the antistatic performances of the sole.

Description

Technical field: [0001] The invention relates to an antistatic agent, in particular to a preparation method of an antistatic agent for PVC shoe soles. Background technique: [0002] In the past, most of the materials used for shoe soles did not have natural materials, so the phenomenon of static electricity generated by friction was not taken seriously by people. However, with the development of petrochemical and electronic industries, polymer materials such as plastic rubber and chemical fibers have come out one after another, and the problem of static electricity has attracted more and more attention from all aspects. Because most of the polymer materials used in shoes belong to the category of electrolytes, their resistivity is very high, that is, the conductivity is very small, so it is easy to accumulate a large amount of charge, which will bring harm to life, production and even life. [0003] The hazard of static electricity refers to the damage caused by electrostat...

Problems solved by technology

[0005] At present, quaternary ammonium salt antistatic agents are often used in polyvinyl chloride for shoe soles, but the main disadvantages of this type of antistatic agents are poor heat resistance and resin compatibility, and the processing and anti-stick properties often decrease during use.
