Kapton production imination equipment
The utility model relates to Kapton production technical field, is specifically related to a kind of Kapton production imination equipment.
Kapton is a kind of novel high temperature resistant organic polymer thin film, be in extremely strong property solvent N,N-DIMETHYLACETAMIDE (DMAC), salivate film forming through polycondensation by pyromellitic acid anhydride (PMDA) and diaminodiphenyl oxide (ODA), then form through imidization.It is the film clasp Y insulation Y material that performance is best in the world at present, has excellent mechanical property, electrical property, chemical stability and very high radiation resistance, high temperature resistant and resistance to low temperature (-269 DEG C to+400 DEG C).Nineteen fifty-nine, first du pont company synthesized aromatic polyimide, within 1962, manufactured experimently into Kapton (PI film), and nineteen sixty-five starts to produce, and trade names are KAPTON.China end of the sixties can small serial production Kapton, has been widely used in now the every field such as aviation, navigation, spaceship, rocket-powered missile, nuclear power, electronic apparatus industry.Be suitable for especially being used as flexible circuit board base material and various heat resisting motor electrical apparatus insulation material.
The production of Kapton is two step method substantially, the first step: synthesizing polyamides acid, second step: film forming imidization.Film mainly contains pickling process (or claiming aluminium foil gluing method), casting method and salivation stretching method.Pickling process equipment is simple, technique simple, but film surface is often stained with aluminium powder, and film length is restricted, and production efficiency is low, and this method should not develop; The film that stretching method is produced, performance is significantly increased, but complex process working condition is harsh, and investment is large, and product price is high; Current employing is more is casting method.
China produces Kapton technology voluntarily and also to update and perfect, but along with the expansion gradually of Application Areas, to the demand of Kapton also in quick increase, for high-performance polyimide film still dependence on import, price is higher, is unfavorable for the products production cost reducing Application Areas.China produces Kapton technology voluntarily and still to have large improvement space.Produce Kapton technology for casting method, the preparation that current urgent need active development is resin dedicated and stable production technology, for Kapton industrialization provides solid basis, fill up the blank of China at correlative technology field simultaneously.Exploitation has the complete set production equipment of independent intellectual property right, and impel the prices of domestic high-performance polyimide film, reduce the cost of its Application Areas, this is very favourable to the development of the industries such as China's electronic apparatus.Current casting method produces the equipment of Kapton, also has a lot of weak point, still needs constantly to improve perfect.Especially, in energy-saving and emission-reduction, material recycle recycling, there is larger deficiency, existing equipment, level of automation is not high, and device control precision is poor, is not easy to on-line monitoring.
Casting method produces Kapton: the polyamic acid solution after froth breaking, is pressed into by the road by stainless steel solution reservoir in the salivation mouth storage tank on front head.Steel band travels at the uniform speed, and is taken away by the solution in storage tank, and forms the uniform liquid film of thickness, then enter and dry road drying through salivation mouth front scrapping plate.
The air of clean dried is sent into after well heater is preheating to certain temperature by gas blower and is entered upper and lower oven dry road.Hot wind flow direction is contrary with steel band traffic direction, to make liquid film temperature when drying raise gradually, solvent volatilizees gradually, increases drying effect.Polyamic Acid Film runs one week with it on steel band, and solvent evaporation becomes solid film, and the film under steel band is peeled off guides imidization stove into through guide roller.
Existing imidization stove is generally multiple roll cartridge form, guides Polyamic Acid Film to enter imidization stove with the guide roller of slobbering machine synchronous speed, after high temperature imidization, by winder rolling.The imidization stove imidization effect of existing structure is not very desirable.Also there is a lot of defect in structure design, equipment is installed and maintenance inconvenience, and cost is high.
