Abstract
The invention relates to a membrane for a sealing bag on the inner wall of a large airplane and a surface treatment method thereof. A plastic membrane is polyvinylidene fluoride (PVDF). The surface treatment process comprises the following steps of: drawing the membrane out on an unreeling roll, treating by a sodium naphthalene complexing liquid treatment tank continuously, washing by an acetone treatment tank, drying by a drying oven, and rolling. The surface treatment method is suitable for large-scale continuous production. The surface of the membrane is subjected to chemical treatment by a treatment method of sodium naphthalene complexing liquid, so that defluorination is performed on the surface of the membrane to form a charring layer, and active groups such as hydroxyl, carbonyl, unsaturated double bonds and the like are introduced; the thickness of the membrane is between 12 and 37 micrometers; corrosion holes are distributed on surfaces of both sides of the membrane uniformly, and 0.1 to 0.2 millions of corrosion holes are formed on surface per 1 square centimeter of the membrane; the depth of each corrosion hole is between 0.5 and 1.0 micrometer, and the bore diameter is between 0.02 and 0.2 micrometer; and the surface energy of the treated membrane is between 300 and 500 muN/cm, a contact angle of the membrane on water is between 80 and 125 degrees, and the peel strength is between 30 and 55 N/inch.
Description
Technical field
The present invention relates to a kind of surface treatment method of film, particularly a kind of film and surface treatment method thereof for large aircraft inner wall sealing bag.
Background technology
Although global commercial aircraft industry has been subjected to up till now recessionary the impact, but the long term prospect of global commercial aircraft industry is still good, for the most important product of the sector-for narrow body and the wide-bodied aircraft of passenger traffic and shipping, namely the large commercial aircraft is particularly like this.
Prediction to following 20 years shows, about 5% with increasing every year as the charge passenger mileage number of global commercial aircraft industry motivating force, this is the twice of whole global economy predicted growth rate.Order at 2006 and commercial aircraft in 2007 also reaches the newly the highest of 4000 of accumulative totals.Nowadays, 36% of the overstocked order total amount of large commercial aircraft is the order of Asian Aviation company.In fact, China is the biggest market of the new commercial aircraft of Boeing Co. and European Airbus SAS at present.Recently, the inspirer prediction of another one is that the aircraft order amount of money is estimated to reach 3.2 hundred million dollars.
At present, just in the domestic commercial aviation industry of develop actively, aerospace and national defence industry practitioner are about 500,000 people in China, and one of them company-Aviation Industry of China group company has entered air market with ARJ 21 these secondary-line-aircrafts of new generation in the recent period.China has created a new company-China Business Plane Co., Ltd recently, and the said firm clarifies a plan and produces large aircraft before the year two thousand twenty.Under the support and a large amount of effort through the good slip-stick artist who trains of government, probably in the near future, the global manufacturer of the 3rd large commercial aircraft can appear in the whole world.
The aircraft of Boeing Co. and European Airbus SAS has been installed a kind of sound insulation insulated enclosure bag between main cabin interior trim layer and body covering, that this material has is heat insulation, the function of sound insulation, fire-retardant and insulation.Aircraft inner wall sealing bag is by filled glass fiber felt in the poly(vinylidene fluoride) bag film, is prepared from through ultrasonic sealing poly(vinylidene fluoride) bag film bag again.The reason of selecting this material of poly(vinylidene fluoride) is because it does not fire, molten, odorlessness, does not make propagation of flame, and still can keep softness and usability under extreme temperature.In addition, this poly(vinylidene fluoride) film and glass mat meet United States Government about the regulation of the refractory insulating material that uses in the fuselage of large aircraft.Prepare this poly(vinylidene fluoride) bag film and adopted special technique, at film the reinforcement fibre line structure is arranged, therefore improved resistance to tearing and over-all properties.Simultaneously, on film, also be coated with can ultrasonic sealing glue, conveniently make sealing bag.
The people such as Yializis, Angelo is 6 in the patent No., 960, a kind of polymer composite film is disclosed in U.S.'s patent of invention of 393, its concrete technical scheme is: polymer composite film comprises that one deck is through graft polymerization second polymer film on the film of Surface Treatment with Plasma, then at the laminated film process plasma grafting polymerization the first polymeric film that generates, the polymer composite film that obtains has higher thermal stability and better mechanical property.There are many Application Areass in this polymer composite film, comprises food product pack, film capacitor, metallization, aluminum foil metal evaporation tape, flexible cable and decoration and various optical thin film.One or more metal levels may be deposited on the surface through the film of the acrylic polymer of Surface Treatment with Plasma or radiation curing.One ceramic layer also may be deposited on the acrylic polymer surface of radiation curing so that oxygen barrier gas and moisture-proof film to be provided.The making of laminated film be use one fast, high vacuum polymer deposition process, can form ultra-thin, even, high temperature resistant, crosslinked acrylate polymers on specific thermoplastics or heat cured polymeric film.Radiation curing can be used for the crosslinked of acrylate monomer.Laminated film can be consistent with metallization production process or ceramic coating, finishes simultaneously at same vacuum chamber with minimum extra-expense.
The people such as Lawall are 7 in the patent No., 909, the activation treatment that is used for the PVDF film of aircraft seat is disclosed in U.S.'s patent of invention of 403, concrete technical scheme is: a kind of aircraft seat that can regulate, can regulate geometric configuration and position, seat surface has the PVDF film, and film surface is through activation treatment.
