Abstract
The invention relates to a repair method for an aluminum coating of a composite material. The repair method includes the following steps that firstly, a damaged position is ground, wherein the aluminum coating damaged area on the surface of the composition material is confirmed, and the aluminum coating damaged area is subjected to grinding pretreatment through abrasive paper; secondly, a repair area is designated, wherein the portion beyond the repair area is covered with paper adhesive tape and craft paper; thirdly, repairing is performed, wherein an aluminum coating is sprayed to a to-be-repaired area through a spraying device; fourthly, coating detection is performed, wherein the repaired aluminum coating is subjected to resistance measurement through a spray aluminum coating resistance detector; and fifthly, within 24 hours of repairing of the aluminum coating, a layer of epoxy hole sealing agent is sprayed on the repair area. The repair method is easy to operate, consumable items in use are cheap and easy to obtain, the damaged spray aluminum coating can be effectively restored, operation can be performed indoors, and the defects in the method of the prior art are overcome. Because local repairing is adopted, compared with overall spraying in the prior art, damage to a composite material base body is relieved as much as possible, and the repair quality is guaranteed.
Description
Technical field
The present invention relates to the aluminized coating reparation side in patching coating Technology field, specifically composite
Method.
Background technology
For meeting composite material surface electrical property, generally prepare one layer of aluminized coating at composite material surface.Compound
Material in use, during as used as airplane component, is on the one hand understood by dust storm in aircraft flight
The impact of the external environment conditions such as erosion, sandstone shock；On the other hand, in repairing composite material, can be subject to
Collide with to hard things such as instruments, scratch, or due to factors such as multiple material structure repair, cause the aluminum on multiple material surface to be coated with
Layer local is destroyed, thus affects composite material surface electrical property.
At present, prior art has multiple material surfaces of aluminum coating production, but is badly in need of the reparation side of local damage
Method.For meeting factory's repairing requirement to this kind equipment, carry out composite material surface aluminized coating local route repair work
Process research tool is of great significance.
Prior art, the most frequently used repair mode is: after all removing the aluminized coating of composite material surface,
Again prepare, but the method workload is big, relatively costly, the wasting of resources, the rapid wear when removing aluminized coating
Bad matrices of composite material, can cause derivative defect.People need one can bonded composite feature and
Surfaces of aluminum coating production and production scene practical situation, solve that prior art workload is big, be easily generated
The method for repairing and mending that derivative defect etc. are not enough.
Summary of the invention
For the defect of above-mentioned technology, the present invention proposes the aluminized coating restorative procedure of composite.
The aluminized coating restorative procedure of composite, comprises the following steps:
(1) beat fray: confirm composite material surface aluminized coating failure area, use 180#～400# sand paper
Aluminized coating failure area is carried out polish pretreatment, during polishing must not damaged composite material matrix, after polishing use
The cleaned surface of acetone；
(2) patch area delimited: use paper self-adhesive tape, kraft paper to cover the part beyond patch area；
(3) repair: use the 16E spraying equipment of Sulzer Metco company to treat patch area spraying aluminum and be coated with
Layer, need to use infrared ray thermoelectricity instrument monitoring composite element surface temperature, when composite structure during spraying
When part surface temperature is close to 50 DEG C, stop operation, after temperature cools down, again carry out repair；
(4) coating detection: use aluminium-plated coating resistance detector to carry out resistance survey to repairing later aluminized coating
Amount, coating resistance to be controlled is at 0.5～1.3m Ω；If resistance is less than the value range of regulation, aluminized coating need to be removed,
Again spray；If higher than the value range of regulation, need to fill spray aluminized coating, until resistance value is qualified；
(5), in 24 hours after aluminized coating is repaired, one layer of epoxy hole sealing agent is sprayed at restoring area, complete
Become repair.
The invention has the beneficial effects as follows:
The present invention is simple to operate, use consumptive material cheap and easy to get, it is possible to the aluminium-plated coating of effective Recover from damaging,
And the deficiency in art methods can be overcome at in-house operation.Owing to using sectional repair, with existing
Integral spray again in technology is compared, and the fewest alleviates the damage to matrices of composite material, it is ensured that
The quality repaired.
