Description
Technical field
The present invention relates to antistatic aids, specifically fuel charger anti-static rubber tube and preparation method.
Background technology
In fuel charger refueling process, fuel oil is pumped out from sunken tankers, flow through buried pipeline, fuel charger gut line,
The components such as filter, flowmeter, petroleum vapor recovery regulating valve, sebific duct and refueling nozzle, during fuel flow in these equipment
Wall friction will produce electrostatic, especially nonmetal structure, such as filter and sebific duct.
The electrostatic risk of fuel charger is that gas station needs the security risk paid close attention to, but is advised in previous Safety of Gas Station
In fixed, antistatic more focuses on the ground connection of equipment and releasing for static electricity on human body, smaller to the concern of electrostatic charge of oil.Actually work as oil
When between case mouth and refueling nozzle without forming effectively bridging, oil product charge density is higher in refueling process, can be exported in refueling nozzle
Place forms potential difference, generates static discharge phenomenon.
Under increasing operated pressure, there is an urgent need to the means such as improve oiling flow velocity and refuel in emptying for gas station
The sales volume in the unit interval is improved, these demands also propose stern challenge to the electrostatic safety of gas station.
Steel wire braid is all usually added in current fuel charger sebific duct, improves anti-rolling performance, while reinforcing hose is led
Electrically.A kind of " the fuel charger sebific duct for carrying braiding layer " is elaborated if ZL201320349221.0, such hose assembly is usual
Resistance is in 4 Ω hereinafter, the conducting of fuel-servicing equipment can be realized effectively.But in refueling process, oil product and steel wire braid are not
It is in direct contact, sebific duct internal layer is usually nitrile rubber, and the electric conductivity and antistatic property of interior glue are poor, the oil that can still flow through
Product are rubbed to carry a large amount of charges.
Invention content
In order to solve the problems, such as to easy to produce a large amount of electrostatic in existing fuel charger sebific duct, the present invention is at sebific duct using anti-
Electrostatic designs can effectively reduce the charge density for flowing through sebific duct oil product, prevent the generation of electric discharge phenomena, can effective guarantee add
The safety of oily process lays the foundation the technological means such as to increase oiling flow velocity and refueling in emptying.
The present invention solve its technical problem the technical solution adopted is that：A kind of fuel charger anti-static rubber tube, from the inside to the outside according to
Secondary is antistatic backing, inner glue layer, braiding layer and outer glue-line.
The antistatic backing is formed by adding nano carbon black powder in base PTFE.
The present invention also provides a kind of preparation method of fuel charger anti-static rubber tube simultaneously, and this approach includes the following steps：
（1）Carbon black powder is disperseed using polyurethane ball-milling pot zirconium oxide balls, Ball-milling Time 20-24 hours, ball milling turns
Speed is 8000-11000r/min, system pH 7-9, obtains stable carbon black slurry；
（2）Carbon black slurry is added in PTFE emulsion, carbon black additive amount is 1.5-2.0wt%, and stirring at low speed obtains stable carbon black
PTFE mixed liquors；
（3）Extrusion aid is added into mixed liquor, using paste extrusion molding, squeezes out PTFE layers of carbon black, i.e. antistatic backing；
（4）Inner glue layer is processed in mixer, is squeezed out and is coated on antistatic backing；
（5）By braider, braiding layer is coated in inner glue layer outer wall；
（6）Outer glue-line is processed in mixer, is squeezed out and is coated in braiding layer；
（7）Vulcanizing treatment is carried out to pipe, curing temperature is 150-160 DEG C, vulcanization time 100-110min.
The fuel charger anti-static rubber tube of the present invention has the advantages that compared with prior art：In common sebific duct
On the basis of increase carbon black PTFE antistatic backings, antistatic backing has the characteristics that not adhere to, it is small to rub, and after being added to dispersion
Conductive nano carbon black materials effectively increase the static conductive ability of internal layer, can electrify to avoid oil product, and effectively guide existing
Electrostatic charge of oil charge.The preparation method step of the present invention is simple, technical maturity.
Description of the drawings
Fig. 1 is the structural schematic diagram of the fuel charger anti-static rubber tube of the present invention.
Specific implementation mode
As shown in Figure 1, the fuel charger anti-static rubber tube of the present invention, is followed successively by carbon black PTFE antistatic backings 1, interior from the inside to the outside
Glue-line 2, braiding layer 3, outer glue-line 4.Inner glue layer material is nitrile rubber, and outer glue-line is neoprene, braiding layer using steel wire and
Fiber shuffling.
The fuel charger anti-static rubber tube of the present invention, is prepared by following steps：
（1）Carbon black powder is disperseed using polyurethane ball-milling pot zirconium oxide balls, Ball-milling Time 22 hours, rotational speed of ball-mill is
9000r/min, system pH 8 obtain stable carbon black slurry；
（2）Carbon black slurry is added in PTFE emulsion, carbon black additive amount is 1.7wt%, and stirring at low speed obtains stable carbon black PTFE
Mixed liquor；
（3）Extrusion aid is added into mixed liquor, using paste extrusion molding, squeezes out PTFE layers of carbon black, i.e. antistatic backing；
（4）Inner glue layer is processed in mixer, is squeezed out and is coated on antistatic backing；
（5）By braider, braiding layer is coated in inner glue layer outer wall；
（6）Outer glue-line is processed in mixer, is squeezed out and is coated in braiding layer；
（7）Vulcanizing treatment is carried out to pipe, curing temperature is 150 DEG C, vulcanization time 100min.
The fuel charger anti-static rubber tube of the present invention, antistatic backing is using the polytetrafluoroethylene (PTFE) for adding conductive nano carbon powder
PTFE material, PTFE have surface tension minimum in solid material, do not adhere to any substance, can reduce in oil product and sebific duct
Frictional force when wall contacts.Meanwhile the addition of carbon black improves the electric conductivity of internal layer, can be improved using conductive nano carbon black
Dispersibility of the conductive black in PTFE, the electric conductivity of material can be effectively improved by adding a small amount of carbon black, avoid excessive addition
Material property caused by carbon black reduces and poor processability.
