The invention discloses a PVC (polyvinyl chloride) sole antistatic agent and a preparation method thereof. The PVC sole antistatic agent comprises the following components in percentage by weight: 65-70% of common antistatic agent and 48-55% of silver ion or lithium ion solution. The preparation method comprises the following steps: (1) adding aniline-3,5-disulfonic acid into a sodium hydroxide water solution in multiple times, gently heating until the aniline-3,5-disulfonic acid is completely dissolved, filling into a stainless steel pressure reaction kettle of 200L, and filling a styrene-maleic anhydride polymer; (2) closing the reaction kettle, starting to stir, heating to 170-180 DEG C, and reacting under the condition that the pressure in the kettle is 8-9 atmospheres for 10 hours; (3) after the reaction is finished, cooling to room temperature, opening the reaction kettle, and regulating the pH value of the product to 7-8 with a small amount of acetic acid, thus obtaining a common antistatic agent; and (4) adding 0.3-0.8M of quaternary ammonium lithium chloride solution into 1.2-2.5g of common antistatic agent to obtain the finished product. The PVC sole antistatic agent disclosed by the invention has the advantages of scientific formula, low cost and simple preparation process, and can enhance the antistatic property of soles.
Description
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 a kind of novel PVC sole antistatic agent 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:

Preferred as technique scheme added properties-correcting agent in the common antistatic agent.
Preferred as technique scheme, described properties-correcting agent is zinc oxide, zinc sulfate, zinc nitrate, zinc chloride, thanomin, ethanol, the one or more combination thing in the polyoxyethylene glycol.
The preparation method of PVC sole antistatic agent of the present invention comprises the steps:
(1) with aniline 1,5 one disulfonic acid divide and to join in the aqueous sodium hydroxide solution for several times, and low-grade fever treats that it installs in the 200 L stainless steel pressure reactors after molten entirely, reinstalls vinylbenzene one maleic anhydride polymkeric substance;
(2) with the reactor sealing, start stirring, be warming up to 170-180 ℃, the about 8-9 of a still internal pressure this moment normal atmosphere reacted 10 hours with this understanding;
(3) after reaction finished, cool to room temperature was opened reactor, transferred product pH=7-8 with small amount of acetic acid, namely made common antistatic agent;
(4) in common antistatic agent 1.2-2.5g, add 0.3-0.8M quaternary ammonium lithium chloride solution subsequently, get product.
