Abstract
The present invention is a kind of explosion-proof conducting gel, and it is made up of monomer, linking agent, initiator, natural polymer, the power and water medium of energy synthetic macromolecule.Replace a part of synthetic macromolecule with natural polymer, can reduce the cost of conducting gelation greatly, but do not influence the electroconductibility and the viscosity of gel.And matter remains unchanged for a long period of time.Conducting gap, uniform electric field can be used in and make electro-conductive material in the shocking preventing technology preferably.
Description
The present invention relates to a kind of electro-conductive material, is a kind of explosion-proof conducting gel specifically.
At present, the lightning protection measures of the petroleum storage tanks made from concrete reinforcement is mainly used lightning conduction and lightning rod bonded method, but lightning-arrest effect is undesirable.For lightning protection better, except on oil tank, setting up the guard, it is electric integrated also to need oil tank itself to realize, promptly a kind of explosion-proof conducting gel is filled in the gap between oil tank top and tank skin, the gap between tank deck two arch bars, utilize its electroconductibility homogenizing electric field, reduce voltage between the gap, prevent that the gap from the blast that corona, electrical spark cause taking place under lightning induced voltage and electrostatic interaction.And tight sealing process need be arranged, and stop the interior oil gas of oil tank to ooze out, thereby reduce the danger that tank deck produces spark and blast, can reduce the loss of oil plant simultaneously, avoid contaminate environment.Therefore, this explosion-proof conducting gel not only will have electroconductibility, and performance will stablize, and with concrete, metal etc. adhesive effect is arranged, and price wants cheap simultaneously.Because of requirement is big, as too expensive, cost too higher position is not suitable for a large amount of uses.The conducting material of similar this glue also has much.But they mainly use aspect the soil treatment around the ground-electrodes such as dried tower at equipment, transmitting line, buildings, mainly are to be used for reducing contact resistance and stake resistance (special permission discloses clear 49-131976).Yet there are no and be used to the corona electrical spark aspect that prevents that thunder and lightning, static etc. from causing.This class conducting material mainly is made up of synthetic macromolecule, dielectric medium and water or is made up of the monomer that can form macromolecular material, linking agent, initiator, power and water medium.Synthetic macromolecule cost height, a large amount of use is unfavorable for realizing in the oil tank lightning protection measures electric integrated.
The purpose of this invention is to provide a kind of have electroconductibility and stable performance, the explosion-proof conducting gel that price is low again.
Explosion-proof conducting gel of the present invention is made up of monomer, linking agent, initiator, natural high molecular substance that can synthesized polymer material and the dielectric medium that can form conducting material in water.Above-mentioned substance all can be water-soluble.The monomer of the energy synthesized polymer material that the present invention is selected is vinylformic acid and its esters, acrylic amine and its esters.The intramolecule of these materials all has two keys that polymerization, crosslinking reaction can take place, and one or both mixing of these materials are dissolved in the water, and under action of evocating, itself just can polymerization reaction take place, meets linking agent crosslinking reaction can also take place.Generate the macromole of polymer or network structure, this macromole can wrap up the water around it tightly, forms and contains the gel of big water gaging, and contain conducting material-dielectric medium in the water, just can form conducting gelation.The selected initiator of the present invention is an oxidation-reduction system, and temperature is lower during this decomposition of initiator, therefore just initiation reaction can take place at normal temperatures and pressures.This class initiator has persulphate, hydrogen peroxide, iron trichloride, trolamine etc.It is N that the present invention adopts linking agent, N '-methylene-bisacrylamide, and two two keys that chemical reaction can take place are contained in this material molecule inside, and therefore, crosslinking reaction can take place in it and monomer, and the conducting gelation of generation has insoluble not molten characteristic.Dielectric medium of the present invention is sodium-chlor, Repone K, sodium sulfate, vitriolate of tartar, sal epsom, calcium sulfate etc.They all can form the aqueous solution of electroconductibility.Also add natural macromolecular material among the present invention, its objective is the amount that can reduce synthetic macromolecule, thereby reduce cost, but do not influenced the intensity and the viscosity of gel.Natural macromolecular material of the present invention has carboxymethyl cellulose or starch.Each set of dispense of conducting gelation of the present invention is such as descending (weight ratio): monomer: initiator: linking agent: natural polymer: dielectric medium: water=1: 0.1～0.2: 0.08～0.1: 0.5～1: 3～5: 20.
Embodiment:
0.9 kilogram of acrylamide
N, 0.08 kilogram of N '-methylene-bisacrylamide
0.017 kilogram of Ammonium Persulfate 98.5
0.08 kilogram of trolamine
3.0 kilograms in sodium-chlor
18 kilograms in water
0.5 kilogram of starch
Using method of the present invention: take by weighing each component by above prescription, beyond the sulphur removal acid amide, all the other components all mix, and add Ammonium Persulfate 98.5 again and stir rapidly when using, and recharge in the slit, after waiting to solidify, bury with soil.
Explosion-proof conducting gel by above-mentioned gained not only has excellent conducting performance, and viscosity and intensity preferably arranged, this gel matter that remains unchanged for a long period of time, do not run off, so conducting gap preferably, uniform electric field can be avoided the fire that spark, corona caused, blast on the oil tank that thunder and lightning static causes.This gel cost reduces greatly, and its price is 1/3rd of the gel formed of synthetic macromolecular material.
