Description
Technical field
The present invention relates to a kind of resistance value adjustment methods of polystyrene foam bead surface utter misery.
Background technique
Resistance is the distinctive physical parameter of conductor, and the size of resistance and the material of conductor are related, resistance it is whether useful and
What plays, is critical to see to bring what use done；Resistance is small and is easy to conduct the substance of electric current and is known as conductor, and resistance is greatly and not
The substance for being good at conducting electric current is known as insulator, and the substance to fall between is known as semiconductor.
In order to increase the electric conductivity of substance, we will recognize that with metal, inorganic (ionization series, carbon system, metal oxide system),
The conductive materials such as compound (inorganic-organic) type macromolecule conducting material, structural type macromolecule conducting material.But each material
The applicable aspect of institute be also it is different, still must proceed from the reality, suitable one party is found in particular problem concrete analysis
The conductive material of face demand.Present invention seek to address that the resistance value of polystyrene foam bead surface utter misery is reduced, in pre-stage test
We are found by experiment that the increase with acetylene carbon black dosage only with single acetylene carbon black as conductive material in work
Sheet resistance value is declined, but it is minimum also can only achieve 3600~4100 ohms, resistance value cannot reach expected effect
Fruit, therefore cannot reach the demand of application, a kind of method reducing resistance value have to be developed.
Summary of the invention
The object of the present invention is to provide the resistance value adjustment method of polystyrene foam bead surface utter misery, a kind of reduction resistance value
Method.
Present invention technical solution used in order to achieve the above object is:
A kind of resistance value adjustment method of polystyrene foam bead surface utter misery, is to mix acetylene carbon black and other structures charcoal
Coating liquid is made in conjunction, is coated in polystyrene foam bead surface；The coating liquid raw material composition presses the weight percent of solid content
Than are as follows: acetylene carbon black 25%~40%, other structures charcoal, adhesive 45%~55%, surplus are other non-conductive auxiliary agents；Wherein
The other structures charcoal are as follows: superconduction carbon black 3%~7%, expanded graphite 6%~18%, nano-graphite 6%~18% or carbon nanometer
Pipe 3%~7%.

Nanotube preferably 6%.
In method of the invention, the preferred styrene-acrylic emulsion of adhesive is not lose powder and water resistance after guaranteeing coating 4 times, test
It is minimum with 45% afterwards, therefore it is preferred that 45%.Other adhesive can be used to substitute.Conductive material of the invention is using acetylene carbon black and its
The mixing of its structure charcoal, other structures charcoal use: high structural type superconduction carbon black section qin EC-600JD, expanded graphite (10 microns),
Nano-graphite (0.5 micron), carbon nanotube (30-50 microns)；By the acetylene carbon black of certain solid content mass percent and not
Other structures charcoal with solid content mass percent matches mixing, using styrene-acrylic emulsion as adhesive, the coating that is prepared
Liquid is coated in polystyrene foam bead surface, passes through test: being then not easy to stir drying, weight ratio according to weight ratio 10:9
10:7 then coats carbon amounts naturally relatively rarely, then determines to obtain optimal maximum mixed proportion using polystyrene foam bead
It is 10:8 with coating liquid fixed weight ratio, coating pass is fixed as 4 times, measures quilt by QUICK499D sheet resistance tester
The polystyrene foam bead surface resistance value that coating is 4 times, passes through measured value and the single coating situation pair using acetylene carbon black
Than sheet resistance value is substantially reduced and can reach necessary requirement.Coating liquid of the present invention, mainly by acetylene carbon black point
Water and dispersing agent high speed grinding is not added to mix with other structures charcoal, later, using styrene-acrylic emulsion as adhesive and addition
Other non-conductive auxiliary agents, are dispersed with stirring according to constant weight ratio and are mixed into coating liquid.
In the present invention, the coated carrier used is polystyrene foam bead, density 20kg/m3, the small ball's diameter
Between 1-4mm.
Coating method employed in the present invention is as follows, and every all over coat weight mixed proportion 10:8, (polystyrene foam is small
Ball: coating liquid), it coats 4 times, according to device therefor and environment temperature and damp condition, guarantees that every time particle is substantially at dispersion
State carries out next time coating again on this basis, coats 4 times and can carry out sheet resistance value survey after thorough drying overnight
Amount.
In the present invention, after completing above-mentioned coating method, it is coated 4 times using the measurement of QUICK499D sheet resistance tester
Polystyrene foam bead particle surface resistance value.Using the mixed of solid content weight acetylene carbon black 25%+ superconduction carbon black 6%
Conjunction mode, measuring sheet resistance value is 350~450 ohm；Solid content weight acetylene carbon black 25%+ expanded graphite 9% or 12%
Hybrid mode, measure sheet resistance value be 410~480 ohm；Solid content weight acetylene carbon black 25%+ nano-graphite 9%
Hybrid mode, measuring sheet resistance value is 560~750 ohm；Solid content weight acetylene carbon black 25%+ carbon nanotube 6% is mixed
Conjunction mode, measuring sheet resistance value is 300 ohms.
The present invention mixes acetylene carbon black with other structures charcoal respectively, and it is small to be coated in polystyrene foam after adding glue to mix
Ball surface can be substantially reduced resistance value, and 300~480 ohms, every surface can be reached by measuring sheet resistance value after coating 4 times
Utter misery small spherical particles can be connected and resistance is lower.Compared with the coating situation for only with acetylene carbon black being conductive material, using this
The particle surface resistance value that 4 times polystyrene foam beads are coated after invention reduces 10 times or so, is a kind of effectively tune
The method for trying resistance value.
