Description
Technical field
The present invention relates under low temperature curing conditions, igniter aluminium box glues the adhesive technology of composite material with carbon fiber difficulty.
Background technique
Igniter device is an important component in solid propellant rocket.Aluminium box igniter is Nian Jie with carbon fibre material
Product structure formed by converging portion liner and with medicine igniter device.Converging portion liner bonding plane is that difficult bonding carbon fiber is compound
Material, igniter device bonding plane are aluminium alloy, and bonding plane is the cooperation of cone of revolution body, and the two is bonded using adhesive.
The connection structure of bonding way is light-weight, can connect the material of unlike material.With the raising of solid propellant rocket performance,
It is influenced by engine enlargement, the complexity of the bonding interface of igniter and converging portion liner is continuously improved, in converging portion
Lining is widely different with aluminium box igniter fit clearance, and bonding gap difference can achieve ten times or more, and bonding process midpoint
It cannot be with the presence of adhesive in the fire hole of firearm device.For the bonding requirements for meeting igniter device, adhesive is first had to pair
Good wellability is had by viscous part；Secondly, adhesive solidification process uses contact pressure；Again, bonding agent has
Preferable thixotropic behavior not only can smoothly fill the fit clearance of 0.01mm or so, but also can fill part 0.2mm~0.3mm and match
Gap is closed, is not in gummosis in solidification process.It is influenced by solid propellant rocket igniter, bonding agent needs
Solidify under conditions of room temperature or a little higher than room temperature, without complicated heating pressurized equipment.Bonding agent solidification after shear strength answer >=
20MPa, to meet igniter device bonding reliability requirement.
The structural adhesive generally uses epoxy resin as basic component, poly- using polyamine, modified amine, low molecular weight
Amide etc. is curing agent, passes through the components such as addition diluent, thixotropic agent, toughener, reinforcing agent, coupling agent, filler, dispersing agent
Obtain expected service performance.Select different types of epoxy resin and curing system, the type of each function ingredients and each function
A series of different bonding agent of performances can be obtained in conspiracy relation between energy component.Existing association between each function ingredients of bonding agent
Same-action influences each other again, if each group component selections and proportion are unreasonable, will cause adhesive performance defect, certain extreme
In the case of bonded structure can be made to fail, cause solid propellant rocket work failure.
Adhesive components select to manufacture the core technology in use for adhesive with each group distribution ratio, while being suitable for solid
The bonding agent that rocket igniter device is bonded this particular components is used as military product, it is difficult in open source information
It is difficult to find relevant information.Aerospace industry standard QJ1922.1~QJ1992.25 series standard is to space product adhesive
Adhesive technology standardized, but be not related to adhesive components and proportion.Domestic and international patent is inquired by internet,
The relevant information in terms of solid propellant rocket igniter device adhesive component and proportion relation is not found.
Igniter bonding uses cold curing adhesive at present, which mainly includes epoxy resin and polyamide-based solid
Agent, adhesive strength is 10MPa after adhesive solidification, and curing time is 24 hours, and adhesive strength is low, and curing time is long,
It is not able to satisfy the demand of the type igniter bonding, and jet pipe shell igniting hole plug, igniting dress occurs in technique for sticking process
Set there is offset, igniter case deformation, igniter bonding plane dangerous, jet pipe of polishing solidifys the unstable problem of placement,
Influence the production efficiency and reliability of product.
Adhesive can be divided into normal temperature cure, low-temperature setting, intermediate temperature setting, hot setting by type.Adhesive is all a variety of
Substance, other than playing the substance of basic adhesive attraction, in order to meet specific physicochemical characteristics, it is still necessary to various auxiliary are added
Component meets the performance of adhesive.In order to reduce solidification temperature, energy consumption is saved, glue-line internal stress is reduced, reduces cost, need out
A kind of epoxy adhesive is issued, solidification temperature and pressure requirements are met.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of aluminium box igniter and carbon fibre material adhesive glue is viscous
Agent obtains expected usability by components such as addition curing agent, toughener, fillers using epoxy resin as basic component
Can, it can be improved the adhesive strength after solidifying, reduce curing time, guarantee that the priming system operates in the range of safety.
The technical solution adopted by the present invention to solve the technical problems is: a kind of aluminium box igniter is Nian Jie with carbon fibre material
With adhesive, component include the epoxy resin E-51 of 100~120 parts by weight, 80~100 parts by weight epoxy resin 711,
The mica powder of 100~150 parts by weight, the aluminium oxide of 30~40 parts by weight, the GX-550 of 8~10 parts by weight, 50~60 parts by weight
JLY-121 polysulfide rubber and 80~90 parts by weight 105 contracting amine.
The aluminium box igniter and carbon fibre material adhesive glue stick using it is preceding first to igniter device bonding plane into
Row blasting treatment is polished in converging portion liner bonding plane using sand paper, using equal in bonding plane after acetone cleaning bonding plane
Even smearing aluminium box igniter and carbon fibre material adhesive glue stick, and it is Nian Jie with carbon fibre material to clear up extra aluminium box igniter
It with adhesive, is finally pressurizeed using tooling, 4h is kept the temperature at 60 DEG C and is solidified.
The present invention is pressurizeed using link-type tooling, and the link-type tooling includes pedestal, pull rod, pressing plate and center
Connecting rod, described center rod one end are connected on pedestal, and the other end is external thread structure, pass through attaching nut after pressing plate；Extremely
Few two pull rods are symmetrically connected in center rod two sides, and the aluminium box igniter is mounted between pull rod and pressing plate, passes through rotation
Turn nut band dynamic pressure plate, adjusts the pressure between aluminium box igniter and carbon fibre material.
The present invention does not smear adhesive within the scope of fire hole outer rim radial direction 5mm, and cooperation tooling pin is protected fire hole, protected
Card fire hole does not block.
The beneficial effects of the present invention are: can be to no supporting part medicine aluminium box point using adhesive and process of the invention
Firearm device plays reliable bonding.The adhesive can low-temperature setting, solidification process without small molecule be discharged, bonding solidification need to contact
Pressure has certain toughness, and being suitable for being bonded carbon fiber and aluminium base in solid propellant rocket has seal request
Structural member bonding.The adhesive can also regulate and control the viscosity of adhesive by adjusting the number of filler, control bond
The gummosis of solidification process.Adhesive tool and technical process in technique for sticking method are used equally for solid rocket motor nozzle each
The bonding of part, igniter device similar structures product.
The present invention and common room temperature Adhensive performance correlation data are as follows:
1 invention adhesive of table and room temperature prepare Adhensive performance
