Abstract
A kind ofly strengthen the nonmetal conductive paste that electric equipment lead junction or appliance switch contact portion electric conductivity are used.
This conductive paste is to be made of graphite, carbon fiber or graphite fibre, binder combination.It has under free position and conducts electricity very well, advantage such as corrosion-resistant, high temperature resistant, resistance temperature negative characteristic.And proportion is little, and cost is low.Be the good conductive cream of conduction contact parts such as various leads, switch, slip, contactor, relay, storage battery, electronic component socket.
This conductive paste is specially adapted on the big electric equipment of the various power consumptions of industry such as metallurgy, petrochemical industry, mine traffic, and conduction contact part is had anticorrosion, anti-oxidant, as to reduce line electricity loss of energy effect.
Description
The invention relates to a kind of conductive paste that enhancing electric equipment lead junction or appliance switch contact part electric conductivity is used, particularly a kind of nonmetal conductive paste.
Present existing conductive paste all is to be that aluminium powder and other metal powder add the conductive paste that a certain amount of chemical substance is made with metal particle (powder).This conductive paste detects not conducting with universal instrument under the effect that does not have external force, only just conducting under the effect of external force is so be to belong to neutral conductive paste.This conductive paste is owing to adopt metal dust as conductive carrier, thus exist than great, cost is high, and along with the rising of temperature, the shortcoming that resistance increases.
The purpose of this invention is to provide and a kind ofly all have excellent conducting performance under external force with under the free position, have antiseptic property and descend with temperature rising resistance, electric conductivity is good more, the nonmetal conductive paste of Remarkable Energy Saving.
Technical scheme of the present invention is to adopt the graphite with excellent conductive performance, and carbon fiber or graphitized filamentary material add adhesive, the nonmetal conductive paste that curing agent and compound stir at a certain temperature and constitute as conductive carrier.According to the difference of purposes, various component proportions are also different.It consists of: a, 60-120 order graphite powder account for 35-65%, b, length is the carbon fiber or the graphite fibre 0.5-25% of 0.05-4 millimeter.C, adhesive 64.5-10% stir under the situation of 30-100 degree and get final product, perhaps adopt: d, 60-120 order graphite powder account for 35-65%, e, length are the carbon fiber or the graphite fibre 0.5-25% of 0.05-4 millimeter, f, adhesive 64-7%, g, curing agent 0.1-1%, h, compound 0.4-2%, stirring under the situation of 30-100 degree gets final product, and the adhesive of employing can select for use resinae and oils all can.Curing agent can be selected ethylenediamine, cobalt oxide, potassium permanganate for use, and compound can be selected the carbon foam for use.
The present invention is because to adopt graphite, carbon fiber or graphite fibre be conductive carrier, this material have conduction well, good heat dissipation.High temperature resistant, corrosion-resistant, self-lubricating, nonmagnetic characteristics.And graphite powder in conductive paste in pelletized form, carbon fiber or graphite fibre are needle-like in conductive paste, they form extruding mutually, the conductive chain that contacts with each other with after adhesive, curing agent and compound mix.Because acicular substance is that cross-lapping and space are filled and made original conductive chain become the favorable conductive thing anyhow at granular material, adds that the electric conductivity of the external force effect conductive paste when using is more obvious.Because carbon and graphite itself have high temperature resistant and the resistance temperature negative characteristic, serviceability temperature can be manufactured according to service condition.So the present invention has and conducts electricity very well, and is high temperature resistant.Advantages such as corrosion-resistant, resistance temperature negative characteristic.
The bus that the present invention is suitable for a secondary of range transformer connects partly various leads, bus, busbar, different metal lead, bus coupling part.Various slip contact portions (open-air rainproof, the snow defence that uses, anti-freezing effect).Various electric furnaces, burner coupling part.Various electric switches, disconnecting link.Automatic switch, contactor, relay, storage battery, contact button, electronic component socket contact portion.Conductive paste has the increase contact area to above contact portion, reduces contact resistance, increases the arc extinguishing and the ducting capacity of various contactors, switch.Prevent oxidation of electrically conductive contact portion and corrosion, reduce the circuit electric energy loss.Prevent the tangible effect that has of electric equipment and circuit accident.Thereby improve the security reliability of electric equipment, reduce the maintenance number of times and the expense of electric equipment, prolong the life-span of electric equipment, reach energy-saving safe, have tangible economic benefit and social benefit.The present invention is specially adapted to metallurgy, and on the big electric equipment of the various power consumptions of industries such as petrochemical industry, mine traffic, effect is more remarkable.
