Description
Technical field
The invention belongs to civilian initiating equipment, be specifically related to a kind of antistatic plug for electric detonator.It can be used for the seismic prospecting electric detonator gland, and various millisecond electric detonators are with glands, preventing RF plug for electric detonator, and high insensitiveness plug for electric detonator and Micro-second Electric Detonator are with gland etc.
Background technology
At present, known electric cap gland material uses polyethylene from high pressure process or employing to be coated with the polyethylene from high pressure process gland of conductive paint.Above-mentioned two kinds of glands cause the self-destruction problem easily owing to there is the problem of the static of releasing.And adopt the gland of said structure and the fire tube of steel flanges housing to be assembled together, and can also make accumulation of static electricity, more be difficult to release, need special attention for this reason, otherwise can the producer and user's safety be impacted.
Summary of the invention
The objective of the invention is provides a kind of plug for electric detonator at above-mentioned deficiency, and its security is good, and conduction speed is fast.
Technical solution of the present invention is a kind of plug for electric detonator of design, and it is characterized in that: its gland material composition comprises polyethylene from high pressure process, rubber, carbon black at least, and plasticizer and auxiliary agent are formed according to a certain ratio; Wherein rubber accounts for 38.4～46.7Wt%, and polyethylene from high pressure process accounts for 6.7～12.8Wt%, carbon black accounts for 25.5～30Wt%, and plasticizer accounts for 13.3～14.8Wt%, and auxiliary agent accounts for 3.3～8.5Wt%.
Described rubber is neoprene, poly-isobutyl diene and Oppanol.
Described carbon black is N100 series carbon black or N200 series carbon black or acetylene carbon black and N472 superconduct carbon black.
Described plasticizer is dibutyl phthalate or DBP; Described auxiliary agent is dibutyl ester or dioctyl ester etc.
Be connected with payment to a porter on the described gland.
After described gland was annotated the plug moulding, insulaion resistance was 1K Ω～20M Ω between its pin-Sai; After gland was assembled into detonator, insulaion resistance was 1K Ω～20M Ω between its pin and pin, pin and the shell.
End periphery has the extension boss on the described gland.
Described gland lower end outer surface is the conical surface, and gland lower end cone diameter is less than the middle part column diameter.
The payment to a porter that connects on the described gland is to be communicated in the gland body from the upper surface, and heart yearn is communicated to the lower surface from the upper surface.
The payment to a porter that connects on the described gland is to be communicated to the lower surface from the upper surface.
The principles of science of technical solution of the present invention foundation is the dispersity that the electric conductivity of conduction material depends primarily on inserts.According to seepage theory, originally disperse isolated filler particles after adding dispersant, its volume disperses to reach a certain critical value, then can form continuous conductive path.At this moment ion is in two states, and the one, the contact of interionic generation physics, its electric charge carrier can flow in continuous conductor; The 2nd, interionic can make carrier itself be activated and move because the bonding thin layer of rubber itself exists.Though material composition plays a decisive role, the basic interaction of the dispersity of filler grain and polymer thereof has also determined the electric conductivity of composite.
The invention has the beneficial effects as follows that after detonator adopts above-mentioned conductive plug detonator is being produced, carries, do not acted on when storing.When static at 2000Pf, be not more than when being added to detonator pin-shell under the 8KV condition owing to be connected with payment to a porter on the gland, conductive plug is led away static and is made detonator not quick-fried, when the power supply that detonates fed detonator with the direct current of regulation or pulse current, detonator was detonated.
