Polishing drip tray surface after epoxy glue solidification.
5. drip tray preparation method reinforced by aircraft as claimed in claim 4, it is characterised in that comprise the steps:
(1) blanking: require to become plate cutting some equal portions rectangular slabs according to design；
(2) being dried: put at horizontal or vertical for rectangular slab interval in baking box and be dried, drying temperature is 150 ± 2 DEG C, drying time
It it is 8～12 hours；
(3) plastics sucking moulding: open Packing Machine, is heated to 160 ± 5 DEG C by mould, is put on mold frame by the rectangular slab of drying
Fixing, material temperature is heated to 270 DEG C ± 20 DEG C, uses evacuation plastics sucking moulding；
(4) the cooling demoulding: use compressed air cooling, the blank of plastics sucking moulding is taken off from mould；
(5) sand papering: use sand papering surface, then clean with acetone or dehydrated alcohol；
(6) prepared by epoxy glue: epoxy resin and firming agent are mixed and stirred for 15～20 minutes, epoxy resin and firming agent weight
Proportioning is 100:14～100:18；
(7) consolidation process: a. is coated with one layer of glue to the region that needs reinforcement on draughty workbench, brushes in the same direction,
It is allowed to uniform；B. lay glass cloth on flat board, brushes the epoxy glue prepared, makes epoxy glue thoroughly be impregnated with glass fabric, dry in the air
Put 30～40 minutes；C. the glass fabric after infiltration is taped against glue bearing areas, the bubble in extrusion glass fabric, works as thickness
Time not, it is possible to repave the glass fabric of one layer of infiltration according to above-mentioned laying step；
(8) monolithic finish: the method heated by local removes the pit of material surface, wrinkling, tilting and uniformity defect, repaiies
Drip tray thickness after whole should be greater than 0.8 mm, and locally heating-up temperature is 200 DEG C ± 20 DEG C；
(9) reinforcing area is repaired: when limit and bubbly defect has occurred in glass fabric, is injected by the region openings damaged
Epoxy glue, makes solidification；
(10) engraving molding: carve drip tray blank by drawing dimensional requirement, remove flash removed with sand papering.
6. the preparation method of drip tray reinforced by aircraft as claimed in claim 5, it is characterised in that: it is dried gap between sheet material every layer
It is 30～50 cm.
7. as described in claim 4 or 5, the preparation method of drip tray reinforced by aircraft, it is characterised in that: epoxy resin is EE
1067；Firming agent is the HD3561 that Loctite produces.
8. as claimed in claim 2 the preparation method of drip tray reinforced by aircraft, it is characterised in that: the particle size range of sand paper be 80～
150 mesh.
9. the preparation method of drip tray reinforced by the aircraft as described in claim 4 or 5, it is characterised in that: glass fabric is A-
1100, A-1100S, Volan, BMS9-3, Type H, Type H-2, Type H-3, Classes 3, Classes 4 or
Classes 7。
10. the preparation method of drip tray reinforced by the aircraft as described in claim 4 or 5, it is characterised in that: sheet material is
ULTEM1613。
