Description

A kind of large-scale curved die surface protective film
Technical field
The present invention relates to a kind of large-scale curved die surface protective films, more particularly to suitable for the large-scale epoxy such as wind electricity blade The complex-curved die surface protective film of resin composite materials product.The invention further relates to this kind of die surface protective film abutment joints Sealing technique.
Technical background
Mold, including single side hard mold mold and the two-sided hard mold mold of enclosed etc. are usually used in manufacturing the composite wood of lightweight Gao Gang Expect component, such as wind electricity blade.Common manufacturing process is, by multi-layer fiber fabric be laid in a mold, by vacuum or its The basis materials such as resin are imported into mold by his mode to be combined with fibre reinforced materials, and is cured in a mold, to obtain fibre Tie up strengthened composite product.The large size fibre reinforced composites product such as wind electricity blade commonly uses the complexity song up to 40 meters Face mould has.
Demoulding after curing for the ease of composite product, usually applies releasing agent so that product on the mold surface Not with die adhesion, it is convenient for article removal.Common releasing agent is liquid or wax-like, and is applied on the bigger mold of area These releasing agents inevitably smear uneven and holiday place, in this way when article removal, are easy hair Raw mold sticking, to destroy die surface and product surface.Liquid release agent often contains volatile organic matter (VOC), harm The health of worker.Major part in existing mold is fiber reinforced plastic mold, releasing agent is applied in die surface, due to releasing agent To the corrosiveness of fiberglass, and to ensure the smoothness on fiber reinforced plastic mold surface, need periodically to polish to die surface Maintaining generates the die surface maintaining expense of great number.In addition, releasing agent may be transferred to product surface, seriously Application interface is influenced, therefore needs to polish to product surface before application, take a significant amount of time and manually, increases the system of product Cause this.
Patent of invention CN102905866A describes a kind of mold moulding wind electricity blade with reinforcing material and basis material, Include that solid-state does not glue lining on mold, the not viscous lining of the solid-state includes adhesive coating and polytetrafluoroethylene material layer, adhesive Coating is adhered to die surface, polytetrafluoroethylene material layer and product into contact.Solid-state does not glue lining and to be not required to use releasing agent, and And after hardening, wind electricity blade can be dismantled by easily never viscous lining.Apply polytetrafluoroethylene (PTFE) (PTFE) on mold not glue Lining can exempt the use of releasing agent, and thickness is uniform, but also have its disadvantage：Polytetrafluoroethylene material price itself is high, material It is of high cost；Polytetrafluoro antistick layer is not wear-resisting, in use destruction easy to wear；Due to processing method, the film is readily permeable Resin influences the service life and stripping result of film；Polytetrafluoroethylene (PTFE) process needs high temperature, difficulty of processing big；It is fluorine-containing to lead It is big to environmental hazard after causing its process and discarding；Abutment joint closing is difficult, and rubber belt sealing is often used when being used on mold, Adhesive tape replacement is frequent, time-consuming, and cost increases more；Polytetrafluoroethylene (PTFE) is thermosets, and recovery difficult is big.
