Description
Technical field
Self-relaxation is suitable for bundle after being impregnated the invention belongs to technical field of polymer materials more particularly to a kind of gasoline
Prick elastic tie of Separated explosion-proof filler and preparation method thereof and binding method.
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.
Polyolefin is mostly important with polyethylene, polypropylene, and principal item has polyethylene and some based on ethylene
Copolymer, such as one acetate ethylene copolymer of ethylene, the copolymer of one acrylic acid of ethylene or acrylic vinegar, also polypropylene and some
Propylene copolymer, poly 1-butene, poly(4-methyl-1-pentene), cyclic olefin polymer.It is cheap due to abundant raw material, it is easy to add
Work is molded, high comprehensive performance, therefore is that a kind of yield is maximum, using very extensive high molecular material.Polyolefin has phase
, chemical resistance small to density, water-tolerant；The features such as good mechanical strength, as matrix, through it is antistatic, lead
It is hot and fire-retardant etc. function modified a kind of cheap, easy to process, Separated explosion-proof filler haveing excellent performance to be prepared.
There is scholar to think that the raising of thermal conductivity of material can not cause substantially changeing for fray-out of flame diameter, thus wall
Effect is only the dominant mechanism for preventing flame propagation.A kind of ultra-fine shoddy of activation is prepared in Chinese patent CN107254160A
The reticulated polyurethane foam anti-explosion blocking material of compound, by being added to through dioxygen in traditional reticulated polyurethane foam
Ultra-fine shoddy after water/potassium ferrate compound system activation process is filled modification, the shoddy after this activation
Not only reduce the production cost of reticulated polyurethane material, moreover it is possible to the effective mechanical property for improving reticulated polyurethane material and suction
Wave oil resistivity promotes service life, further promotes 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 itself and No. 92 sample gasoline at 70 DEG C
Compatibility studied.As a result it proves:Polypropylene Separated explosion-proof filler is swollen after long term storage, and mechanical property is bright
Aobvious to decline, Elastic Modulus declines 57.89%, and elongation at break declines 75.88%；The combustibility and electric conductivity of material
It is declined slightly；Gasoline indices change unobvious, and storage performance is unaffected.Therefore, polyolefin-based Separated explosion-proof is filled out
It fills object to be easily swollen in use, seriously undermines the mechanical property of its polyolefin-based materials ontology, it is caused easily to occur
The phenomenon that collapsing seriously affects the service life of polyolefin-based Separated explosion-proof filler.
Based on this defect, the present invention, which uses Separated explosion-proof filler being placed in compressor, to be compressed, and is used in combination elastic tie will
It carries out repeatedly longitudinal tie up.Elastic tie prepared by the invention can be suitably used for numerous Separated explosion-proof fillers, elastic tie
It is compacted in solvent long period of soaking to solve the high molecular material loosely filled for the prestressing force for imparting Separated explosion-proof filler
Filler hole caused by becoming increases and concentrates, and improves traditional givey defect of Separated explosion-proof filler, and it is anti-to improve barrier
The service life of quick-fried filler.Elastic tie prepared by the invention is of low cost, has excellent performance.
