Abstract
The invention provides an antistatic fire-fighting water hose including four parts: an electrostatic conductive rubber inner lining layer, an anti-static linen woven layer, electrostatic conductive rings and a grounding electrode, wherein the electrostatic conductive rubber inner lining layer is prepared by mixing an electrostatic conductive material into rubber; the anti-static linen woven layer is prepared by mixing conductive fibers in a woven fabric, thereby having an antistatic function; each electrostatic conductive ring is formed by thickening one part at a pipe port of the electrostatic conductive rubber inner lining layer in a cyclic annular mode, so that the electrostatic conductive rubber inner lining layer is in a good contact with a fire-fighting joint or a fire-fighting gun head; the grounding electrode is in a good contact with the electrostatic conductive rubber inner lining layer, and is used for realizing indirect grounding of the fire-fighting water hose. Therefore, in a foam ejection process, static electricity generated from friction between foams and a rubber inner lining is released to the ground through the electrostatic conductive rubber inner lining layer, the anti-static linen woven layer, the electrostatic conductive rings and the grounding electrode, so as to avoid foam static electricity accumulation. At the same time, static electricity carried by human bodies can be released to the ground through the anti-static linen woven layer, the electrostatic conductive rings and the grounding electrode, so as to avoid human body electrostatic risk.
Description
Technical field
The present invention relates to the combustible and explosive area such as petrochemical industry Oil & Gas Storage, particularly a kind of antistatic fire hose.
Background technology
Fire-fighting foams is used to fire extinguishing or fireproof, few people considered the electrostatic risk of fire-fighting foams itself in the past, but abroad some accident suspects that therefore the electrostatic problem of fire-fighting foams causes the concern of electrostatic expert by the electrostatic initiation produced in foam coverage process.Correlation test shows, foam is after the ejection of Fire branch head, and electrostatic belt electricity is very high, and therefore the electrostatic how reduced in foam becomes crucial.
In prior art, Chinese Patent Application No. " 201020225202.3 fire hose " highlights the anti-wear performance of fire hose, Chinese Patent Application No. " 200610050510.5 1 kinds of fire hoses and manufacture method thereof " highlights the low cost of material, for retrieving the patent relevant to fire hose antistatic.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of antistatic fire hose, can reduce the electrostatic risk in fire-fighting foams use procedure, avoid the generation of electrostatic accident.
The present invention adopts following technical scheme:
A kind of antistatic fire hose, described fire hose is made up of static conductive rubber liner layer and antistatic flax braid, and described antistatic flax braid is wrapped in outside static conductive rubber liner layer; Described static conductive rubber liner layer is made up of elastomeric material, in elastomeric material, mix conducting electrostatic materials, makes the specific insulation of rubber liner layer be less than 10
6Ω m; Described antistatic flax braid is made up of flax braid, in flax braid, mix conductive fiber, makes the unit volume resistivity of antistatic flax braid of fire hose outside 10
6Ω m ~ 10
8between Ω m; The inwall of described fire hose mouth of pipe place static conductive rubber liner layer is provided with static conductive ring, static conductive ring is connected with earthing pole, described earthing pole is through static conductive rubber liner layer and antistatic flax braid.
Preferably, described conducting electrostatic materials are carbon black, metal oxide or conductive mica powder.。
