Description
Technical field
The present invention relates to graphite technology field, specially a kind of graphite-epoxy heat generating pastes.
Background technique
Graphite is a kind of allotrope of elemental carbon, and the periphery of each carbon atom links the other three carbon atom (row
Column mode is in cellular multiple hexagons) with Covalent bonding together, covalent molecule is constituted, the fusing point of graphite is 3850 ± 50 DEG C,
Boiling point is 4250 DEG C, though through superhigh temperature electric arc calcination, the loss very little of weight, thermal expansion coefficient also very little.Graphite intensity with
Temperature improves and reinforces, and at 2000 DEG C, graphite intensity is doubled, and graphite and carbon product have excellent performance, application
Increasingly extensive, production capacity and benefit present a rapidly rising trend, and therefore, the demand to a kind of graphite-epoxy heat generating pastes is growing.
Currently there are most of heat generating pastes that there are electrothermal calefactive rates is slower, increase working time, stability
It is poor, and when the temperature is excessively high, the decaying of material can be caused, be unfavorable for the use of normal production and living, therefore, asked for above-mentioned
Topic proposes a kind of graphite-epoxy heat generating pastes.
Summary of the invention
The purpose of the present invention is to provide a kind of graphite-epoxy heat generating pastes, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the invention provides the following technical scheme:
A kind of graphite-epoxy heat generating pastes, the slurry include graphite, carbon black, metal powder, synthetic resin, corrosion-resistant agent, dilution
Agent and adhesive, and the weight proportion of the slurry is as follows, and the graphite is 15~30 parts, and the carbon black is 5~15 parts, described
Metal powder be 6~13 parts, the synthetic resin be 6~12 parts, the corrosion-resistant agent be 2~9 parts, the diluent be 5~
10 parts, described adhesive is 3~6 parts.
Preferably, the ratio of the graphite, carbon black, metal powder and synthetic resin is 18~25 parts of graphite, carbon black 8
~14 parts, 6~10 parts of metal powder, 7~10 parts of synthetic resin.
Preferably, described adhesive is the high-temperature-resistant adhesive with heating conduction.
Preferably, the mass ratio of the corrosion-resistant agent, diluent and adhesive is 1: (1.5~2): (1.3~1.7).
It preferably, include iron powder, silver powder, copper powder and aluminium powder, the iron powder, silver powder, copper powder and aluminium in the metal powder
The mass ratio of powder is 2: 1: 3: 2.
Preferably, the synthetic resin is epoxy resin.
Compared with prior art, the beneficial effects of the present invention are:
In the present invention, heat generating pastes are formed using graphite, carbon black, metal powder and synthetic resin, when in use the heat generating pastes
Fever is fast, and temperature adjustment speed is high, can the stable use to normal production and living provide safeguard, reduce mechanical event
Hinder incidence, improves the efficiency of production and living, while the heat generating pastes, rate of decay is slow, high stability, ensure that fever
The service life of slurry has stronger practical value.
