Description
Technical field
The present invention relates to epoxy resin new high-tech material field, in particular to a kind of dedicated asphalt mixtures modified by epoxy resin of respirator composite cylinder
Rouge glue and preparation method thereof.
Background technique
Pressure vessel is metal inner lining, circumferential or wind fibre reinforced composites entirely.Liner plays seals high pressure gas
With the effect of support fiber winding, outer layer fiber winding layer plays the role of support container pressure loading, for main bearing structure.Fiber
Enhancing is used as fibre reinforced materials by matrix of epoxy resin, through wet winding technology.Filament Wound Pressure Vessel with Metal Liners
Light, good corrosion resistance, fatigue resistance is good, high pressure resistant, and security reliability is good, is widely used in light industry military project, medical traffic, boat
Empty space flight, the fields such as new energy.
With advances in technology and develop, new urgent need, such as new energy are also newly proposed to the development of pressure vessel
The pressure reservoir container of power fuel is provided in development of automobile, it is desirable to which lightweight, carrying pressure is high, and structure efficiency is high, airtight
Good, the excellent in mechanical performance of property, the loaded work piece time is long, and security reliability is good etc..Therefore to the reinforcing fiber tree for playing main bearing structure
The performance of aliphatic radical body requires its viscosity to want low, and good to fiber impregnability, working life is long, has ductility, heat resistance etc..Therefore
The biggish epoxy resin of viscosity will be modified, and infiltrate viscosity suitable for fiber to promote to reach.In the prior art, it is
The viscosity of epoxy resin is reduced generally using low viscosity curing agent or another plus diluent means are added.
Most common in low viscosity curing agent is anhydride curing agent, such as a kind of compressed natural gas bottle epoxy resin of patent document
It is solid that acid anhydrides has been all made of in PP Pipe Compound (CN1239608C), a kind of epoxy gas cylinder glue and preparation method thereof (CN103045144B) etc.
Agent.Anhydride curing agent has that volatility is small, toxicity is low, big to the use level of epoxy resin, that epoxy resin can be effectively reduced is mixed
Viscosity after molten, the advantages that validity period is long；But meanwhile there is a problem of that working life is short.Separately plus diluent can be effective past
Toward the viscosity of epoxy resin-base, but the temperature tolerance of system can be also reduced simultaneously.
In addition to this, the toughness that will affect product is added in curing agent, so that the brittleness of product increases, adds so generally requiring
Enter the brittleness that toughener adjusts solidfied material.
Summary of the invention
The object of the present invention is to provide a kind of respirator composite cylinder special epoxy resin glues and preparation method thereof, obtain
