Description
Technical field
The present invention relates to a kind of material, specifically, is the sputter coating that is used to improve archives CD water-proof antibiotic performance, the invention still further relates to this preparation methods.
Background technology
At present; Preferred medium as irreversible data storage medium---can not optical data storage disk be its data storage life-span at the maximum bottleneck of area information storage; That is to say the data that CD that has write down critical data is stored effectively and are reliably read in can how long.
Since initial stage seventies CD storage technique is succeeded in developing as the substitute of TU, in the period of short 20, be that the disc of standard has substituted the novel vector that cassette tape and video tape become music and film with CD and DVD.The advantage that CD storage technique once bragged about oneself when stepping into commercial the use eighties again and again, the numerical digit technology becomes the much more popular rapidly reason of CD storage technique with the long lasting shelf time." CD of CD media and DVD can be used as collectibles once and for all in the ordinary consumer memory.But through the check of 20 Yu years, the collectibles of putting things right once and for all become visionary hope ", thomas Fu Laier says.
Japan is when holding Osaka world exposition in 1970; Two " times capsulae vacuus " had once been buried in the corner in park, city, Osaka; Wherein placed more than the 2000 kind of article of gathering at that time, plant seed and cloth material have not only been arranged, even put into the televisor and the iron pan of Panasonic's board.One of responsible official then fermentation research He Jingchun when accepting an interview, say: " we this ' time capsulae vacuus ' plan is exactly to hope to look at these article in 100 years bury what variation have taken place; maybe I have been dead when answer to a riddle is made known, but the descendant can see that but what is to remain on earth ".The organizer whenever watched the situation of once burying article at a distance from 10 years, and put into when emerging article of epoch again and advance " time capsulae vacuus ", and a music CD is placed into wherein in 1980.After 20 years,, the digger finds that CD dying when taking out CD and check.
The Fu Ersi that once participated in the early stage CD storage technique design seventies says when accepting an interview not long ago: " we planned the limit of age that it can have 150 years when designing CD originally, who expects seeing at present also with regard to 30 years ".Thomas Fu Laier is not taken aback to this, and he explains " the quality examination occupation let me know that I was engaged in can not have thing to put things right once and for all, and first music CD just has been doomed his life-span in the nineteen eighty-two listing ".The DVD film of the eighties CD disc and the nineties is regarded as the collectibles of long-term reservation, with the in harness bookshelf of having laid out of the books of papery, thinks that originally can be used as lifelong collection stays at home.
In fact the problem that threatens the laser disc life-span is mainly from polycarbonate (polycarbonate) resin of what CD surface coverage." Nikkei science " once reminded common people to note the laser disc preservation period problem in storage epoch with the situation of cover story; Spell out in the article; Originally think that corrosion resistant polycarbonate resin failed to live up to people's expectation; Although with the naked eye do not see the variation on it, its tiny corrosion in surface all can cause losing of data information.
The polycarbonate disc base changes under the effect of internal and external factor in the preservation process gradually, loses by the ability of correct reading of data.These processes are mainly reflected in following aspect: 1, physically aged: in fact polycarbonate disc base physically aged is exactly the process that internal stress discharges, and internal stress discharges the further adjustment and slowly to the equilibrated process of back molecule segment.This process mainly influences the mechanical mechanics property of polycarbonate disc base; Secondly can cause the polycarbonate disc base to a certain degree to be out of shape; The 3rd, the light refractive index that this process also can the minimal effect polycarbonate.Obviously, this distortion of coiling basic body generally can show as the disc radial warpage, and the serious crook warp of degree can directly influence the data of optical disk process of reading, even can't read fully.Technological process through the injection moulding of optimization is the key that finally reduces the internal stress warpage; 2, thermo-oxidative ageing: the thermo-oxidative ageing process of polycarbonate, mainly be meant the end group and the side group fracture degraded of macromolecular chain, form the defective of material internal.This process mainly influences the mechanical mechanics property of polycarbonate disc base, prevents that the key of thermo-oxidative ageing is starvation and keeps suitable envrionment temperature; 3, photooxidation resistance: the photooxidation resistance process of polycarbonate mainly is that the photo-oxidative degradation reaction is main: at the aging initial stage, the Fries rearrangement reaction produces radical, and under aerobic conditions, radical acts on the PC chain, brings out a series of photooxidation reactions; The intermediate product of photooxidation reaction continues reaction again, generates phenol, arone, acids product, and simultaneously, the arone class has certain light stabilization, and photolysis reactions is produced certain restraining effect again.The journey of correcting one's mistakes mainly influences the mechanical mechanics property of polycarbonate disc base, secondly is light refractive index and the transparency that has influenced the dish base to a certain extent.Usually; We think; The decline of transparency derives from the difference of the specific refractory power of dish base section material, and the change of specific refractory power possibly come from two reasons: 1. the electronic structure of the photochemical product after the rayed changes to some extent, and there is difference in the specific refractory power of the specific refractory power of these products and PC base material; Thereby, in material, there is the specific refractory power difference; 2. the PC material produces degraded behind UV-irradiation, and the density of PC base material is changed, and this has caused the decline of specific refractory power again.Delay photooxidation resistance, must in starvation, reduce ultraviolet ray coiling the destruction of base; 4, hydrolysising aging: the hydrolysising aging of polycarbonate is mainly by showing following process: the further catalysis polycarbonate-base of impurity hydrolysis such as dihydroxyphenyl propane that polarity suction hydrolysis of ester group produces and NaCL, quicken polycarbonate aged process.In this process, build up under the dual function of two kinds of quiet tension stresss that produce in contraction and moisture, and produce microdefect and destroy data pits shape in polycarbonate material inside, simultaneously, this process has also obviously reduced the optics and the mechanical property of polycarbonate.Therefore, just the increase of the moisture of trace also can cause the obvious quickening of polycarbonate weathering process at last, stops the water absorption course of polycarbonate disc base as much as possible, is the key of slowing down the polycarbonate disk hydrolysising aging; 5, physical disturbance: is conspicuous to the physical disturbance of CD to the influence of the readwrite performance of CD.Because the hardness of polycarbonate material itself approximately only is equivalent to pencil hardness HB level; So use and the preservation process in; The polycarbonate disc primary surface is received slight wearing and tearing all might cause the data of optical disk readout error; Even the data of optical disk completely destroy, the wearing and tearing on CD read and write surface are the most typical reason of CD inefficacy almost.We need seek the abrasion resistance that a kind of simple method increases the polycarbonate disc base; 6, biological degradation: mould almost is the image that storage process cannot be avoided, and normal optical disc storage (humiture) environment can only reduce the erosion of mould to CD polycarbonate disc primary surface to a certain extent; Must take more effective measures to come the growth of mould fungus inhibition, could guarantee data of optical disk prolonged preservation safely and reliably at CD polycarbonate disc primary surface.
