Description

Compound antistatic agent of a kind of PVC sole and preparation method thereof

Technical field:

The present invention relates to a kind of antistatic agent, relate in particular to a kind of PVC sole antistatic agent and preparation method thereof.

Background technology:

The past sole most no natural materialss of material, so the phenomenon of its fricative static is not paid attention to by people.But along with the development of petrochemical complex, electron trade, macromolecular materials such as plastic, rubber and man-made fiber are come out one after another, and electrostatic problem more and more causes the attention of each side.Because footwear belong to the ionogen category mostly with macromolecular material, its resistivity is very big, and namely specific conductivity is very little, thus be easy to gather a large amount of electric charges, thus to such an extent as to bring harm for life, production life.

The harm of static refers to the infringement that static discharge causes the electrostatic sensitive product.The size of static hazard or the severity of static damage depend on the degree of accumulation of static electricity and the electrostatic sensitivity of electrostatic sensitive product.Electrostatic potential is more high, endangers more big; The electrostatic sensitivity of product is more big, the more easy harm that is subjected to static.

Being created in the industrial production of static is that inevitably its harm that causes mainly can be summed up as following two kinds of mechanism.The harm that one, static discharge cause: fault or flase operation that (1) causes electronics, cause electromagnetic interference; (2) puncture unicircuit and accurate electronic component, or impel component ageing, reduce and produce ratio defective product; (3) the high pressure static electricity discharge causes motor, crisis personnel safety; (4) at many inflammable explosive articles or dust.The production place of mist of oil very easily sets off an explosion and fire.Its two, the harm that electrostatic attraction causes: (1) electronic industry, absorption dust, cause the pollution of unicircuit and semiconductor element, reduce yield rate greatly; (2) film and plastics industry make film or film take-up uneven; Film, CD mould dish and are infected with dust, influence quality; (3) cause Printing industry, the paper rolling is uneven, register trouble, and soil pick-up is serious, even the paper bonding, and influence is produced; (4) textile industry causes rhizoid to wave, twine harm such as flower breaks end, yarn is entangled with.Therefore, produce have an electrostatic-proof function and can use with above-mentioned industry in anti-static shoes at the bottom of have great importance.

At present, sole often uses the quaternary ammonium salt antistatic agent with polyvinyl chloride, and is relatively poor but the main drawback of this class antistatic agent is the consistency of thermotolerance and resin, processing and pick resistance in use often occur and descends.

Summary of the invention

In order to overcome above-mentioned defective, the purpose of this invention is to provide compound antistatic agent of a kind of PVC sole and preparation method thereof, it can effectively reduce the static that the PVC sole produces.

The present invention is achieved by the following technical solutions.
