Abstract
The invention discloses the method for surface treatment before a kind of spray painting of composite material blade coating iron at the leading edge, now the surface treatment before main blade coating iron at the leading edge spray painting uses 08416 wash primer, this priming paint has phosphatization salt, there is harm to environment, the phosphorization membrane of generation and the adhesion of enamelled coating are weaker, there is the phenomenon that enamelled coating comes off during use.The method of the present invention handles blade coating iron at the leading edge using AC131 sol gel solutions, the film layer and enamelled coating adhesion of generation be stronger, it is to avoid the defect that enamelled coating comes off, this solution is alcohol acids, smaller to environmental hazard.The surface of coating iron at the leading edge is covered in using sol gel solution (AC131) before main blade coating iron at the leading edge is painted, a kind of conversion film is formed on the surface of coating iron at the leading edge by hydrolysis and polymerisation, so as to strengthen coating iron at the leading edge and the adhesion of enamelled coating.
Description
Technical field
The invention belongs to composite shaping repairing field, it is related to a kind of method of surface treatment before composite material blade coating iron at the leading edge spray painting.
Background technology
Now the surface treatment before main blade coating iron at the leading edge spray painting uses 08416 wash primer, and this priming paint has phosphatization salt, there is harm to environment, and the phosphorization membrane of generation and the adhesion of enamelled coating are weaker, there is the phenomenon that enamelled coating comes off during use.
The method of the present invention handles blade coating iron at the leading edge using AC131 sol gel solutions, the film layer and enamelled coating adhesion of generation be stronger, it is to avoid the defect that enamelled coating comes off, this solution is alcohol acids, smaller to environmental hazard.
The content of the invention
The purpose of the present invention：The purpose of the present invention is that the surface treatment before being painted for existing existing main blade coating iron at the leading edge has the shortcomings that harmfulness using 08416 wash primer, the method for proposing surface treatment before a kind of composite material blade coating iron at the leading edge spray painting.
Technical scheme：A kind of method of surface treatment before composite material blade coating iron at the leading edge spray painting, it is characterised in that comprise the following steps：
Step 1. Solvent degreasing：Coating iron at the leading edge is cleaned with the calico for speckling with butanone；
Step 2. is isolated：The position do not painted with adhesive tape and brown paper isolation；
Step 3.AC131 is coated：AC131 solution is rubbed using spray gun spraying or with clean wiper, it is allowed to which unnecessary solution is flowed down from surface, soaks coating iron at the leading edge surface, it is kept one layer of continuous wet film, is gently obliterated with clean wiper if any redundant solution, after drying, spray-applied primer；
Step 4. is primed：Spray priming paint as defined in drawing；
Step 5. is dried：Normal temperature or heat drying priming paint；
Step 6. is polished：With sand paper polishing prime coat；
Step 7. is cleaned：Adhesive rag cleans grinding；
Step 8. is painted：Finish paint as defined in spraying；
Step 9. is dried：Normal temperature or heat drying finish paint；
Step 10. is examined：Thickness of paint layer, adhesion and outward appearance are detected, surface treatment is completed.
Advantages of the present invention：The film layer and enamelled coating adhesion that AC131 sol gel solutions that the present invention is used are produced be stronger, it is to avoid the defect that enamelled coating comes off, this solution is alcohol acids, smaller to environmental hazard.
Embodiment：The present invention is described in further detail below.
1) main blade coating iron at the leading edge enamelling process process description：
Solvent degreasing → isolation → AC131 → prime → dry → polishing → clean → painting → and dry → inspection
2) AC131 specifications
1. method I：Spraying
A. spray gun AC131 solution is used, it is allowed to which unnecessary solution is flowed down from surface, soaks piece surface, it is ensured that all surface is continuously moistened at least 1 minute.
B. for big part, less region is handled respectively with most short coating time.Gradually covering whole part ensures that processed surface will not be dried in spraying process.
C. the part after coating is allowed to drain off 3-10 minutes.For the region that can freely drain off without drying.If desired, being removed using one of following two method can not freely be drained off or in the presence of the redundant solution on whereabouts side.
(1) redundant solution is blown off using compressed air, while keeping one layer of continuous wet film on surface.Unnecessary solution should not be made to splash neighbouring piece surface.
(2) redundant solution is gently smeared using the clean wiper for being impregnated with AC131 solution, while keeping one layer of continuous wet film on surface.
D. part whole surface is dried to dry to visual and (notice that solution aggregation zone rate of drying slows down).Part can be placed in temperature and reach to be accelerated to dry 60 minutes in 180F baking oven.During this period to prevent destruction or pollution film layer, the contact with part should be reduced until being completely dried.
2. method II：Apply by hand
A. using the sufficient AC131 solution of clean wiper erasing, keep piece surface solution continuous at least 1 minute.Piece surface, which should be dissolved, to be impregnated with；Wiper can not flow down lines in surface again.Piece surface does not allow to be dried in coating procedure.
B. the part after coating is allowed to drain off 3-10 minutes.For the region that can freely drain off without drying.If desired, being removed using one of following two method can not freely be drained off or in the presence of the redundant solution on whereabouts side.
(1) redundant solution is blown off using compressed air, while keeping one layer of continuous wet film on surface.Unnecessary solution should not be made to splash neighbouring piece surface.
(2) redundant solution is gently smeared using the clean wiper for being impregnated with AC131 solution, while keeping one layer of continuous wet film on surface.
Part whole surface is dried to dry to visual and (notice that solution aggregation zone rate of drying slows down).Part can be placed in temperature and reach to be accelerated to dry 60 minutes in 180F baking oven.During this period to prevent destruction or pollution film layer, the contact with part should be reduced until being completely dried.
