Description
Technical field
It is expandable after being impregnated the present invention relates to Separated explosion-proof technical field more particularly to a kind of gasoline suitable for fuel tank
Separated explosion-proof obturator.
Background technology
Separated explosion-proof filler refers to that netted, spherical or other shapes are made using metal or high-molecular organic material as matrix
The material of shape, filling or in vehicle, aircraft, naval vessels, tank fuel tank or in the oil tank of other facilities, pipeline, will be opposite
Larger inner space is divided to form several sufficiently small space structures, and this structure can obstruct rapid propagation and the energy of flame
The abrupt release of amount, and using structure, surface and the heat-conduction effect of material itself, the explosion condition of combustible vapor is destroyed, from
And prevent from further burning and explosion, to ensure the storages of inflammable and explosive petrochemicals, transport and safe to use.Barrier
The mode classification of explosion-proof filler is varied, and Separated explosion-proof filler can be divided into metal Separated explosion-proof according to the property of material
The explosion-proof filler of filler, Nonmetal barrier.
The explosion-proof filler of more typical Nonmetal barrier passes through mainly using high molecular materials such as polyolefin, polyethers as base material
Porous material made from the techniques such as networking processing or injection molding, has small relative density, large specific surface area, cheap etc. excellent
Point is applied to the place more demanding to material weight, such as military civil aircraft fuel tank more.
There are mainly two types of viewpoints for the explosion suppression mechanism of nonmetallic materials：Cold-wall effect and wall effect.Cold-wall effect thinks,
During flame propagation, the huge specific surface area of nonmetallic materials can quickly absorb the heat of flame generation, and porous material
Several cells can be divided the container into, to have the function that dispersed flame Separated explosion-proof；Wall effect thinks, porous non-metallic
Material structure channel has prodigious specific surface area, and when explosive reaction occurs, explosion conduit wall collides with free radical is reacted,
A large amount of activatable free radicals are absorbed, when the free radical of reaction is reduced to a certain extent, explosive reaction terminates.Current cold-wall effect
Approved by numerous scholars, becomes mainstream Separated explosion-proof mechanism.However some scholars think the raising of thermal conductivity of material simultaneously
Substantially changeing for fray-out of flame diameter cannot be caused, thus wall effect is only the dominant mechanism for preventing flame propagation.It is Chinese special
It is prepared for a kind of reticulated polyurethane foam anti-explosion blocking material of the ultra-fine shoddy compound of activation in 107254160 A of sharp CN, leads to
Cross be added in traditional reticulated polyurethane foam it is ultra-fine after hydrogen peroxide/potassium ferrate compound system activation process
Shoddy is filled modification, and the shoddy after this activation not only reduces the production cost of reticulated polyurethane material,
The mechanical property of reticulated polyurethane material can also effectively be improved and inhale wave oil resistivity, service life is promoted, further promote material
The anti-explosion blocking ability of material.
Have scholar (novel polypropylene obstructs explosion-suppressing material and gasoline-compatible Journal of Sex Research [J] China Safety Science journals,
2016,26(8):It 52-57.) is prepared for novel polypropylene Separated explosion-proof filler, and to the phase of itself and 92# gasoline at 70 DEG C
Capacitive is studied.As a result it proves:Polypropylene Separated explosion-proof filler is swollen after long term storage, under mechanical property is apparent
It drops its Elastic Modulus and declines 57.89%, elongation at break declines 75.88%；The combustibility and electric conductivity of material slightly have
Decline；Gasoline indices change unobvious, and storage performance is unaffected.Therefore, polyolefin-based Separated explosion-proof filler
It is easily swollen in use, seriously undermines the mechanical property of its polyolefin-based materials ontology, it is caused easily to collapse
The phenomenon that, seriously affect the service life of polyolefin-based Separated explosion-proof filler.
Based on this defect, porous packing material is placed in press by the present invention to be compressed, and is used in combination elastic tie to be carried out more
Secondary longitudinal direction is tied up, to which a kind of inflatable Separated explosion-proof obturator suitable for fuel tank be made.The invention is existed using elastic tie
It is swollen in gasoline, and slow relaxation, imparts Separated explosion-proof filler prestressing force, which effectively can delay Separated explosion-proof to fill out
The collapse phenomenon generated after object is swollen in the oil is filled, the explosion-proof givey defect of filler of tradition is effectively improved, improves
The service life of Separated explosion-proof filler, prepared Separated explosion-proof obturator have it is of low cost, it is easy to process, have excellent performance
The features such as.
