Description
Technical field
The present invention relates to the technical field of printing plate manufacture, more particularly, be on a kind of temperature-sensitive CTcP plates and
Its preparation method.
Background technology
Single bondline thickness on current traditional plate is 2.6g/cm2, and many coatings are so needed when photosensitive layer is coated,
Photosensitive liquid is so not only wasted, and the thickness of overall plate increases so that and the photonasty of CTcP plates is poor.
The preparation method of current CTcP plates needs by the way of secondary coating and needs to carry out plate cumbersome
Treatment work, and must there is substantial amounts of chemical liquid to need to use and discharge during these, so as to cause the dirt of environment
The shortcomings of dye, complex procedures, high cost and wasting of resources, while needing the workmanship of the film and correlation in preparation process
Material, so needs the substantial amounts of plate making time in printing, and the ageing of plate-making is substantially reduced.
Accordingly, it would be desirable to design it is a kind of can the efficient and convenient printing plate for carrying out secondary coating, printing when can save
A large amount of plate making times.
The content of the invention
Goal of the invention：In view of the shortcomings of the prior art, applicant improves by repeatedly practice, devises a kind of temperature-sensitive CTcP
Plate and preparation method thereof, can cause that the photosensitive property of temperature-sensitive CTcP plates is more stablized and efficient.
Technical scheme：In order to realize foregoing invention purpose, the technical solution adopted in the present invention is：A kind of temperature-sensitive CTcP editions
Material, the temperature-sensitive CTcP plates include aluminium base, and electrolytic graining, oxidation are sequentially coated with from the bottom to top on the surface of aluminium base
Layer, hydrophilic layer, photosensitive layer, protective layer and air guiding layer.
A kind of preparation method of temperature-sensitive CTcP plates, it is comprised the following steps：
Step one, CTcP plates are put into uncoiler carries out uncoiling, smoothing first, then by the CTcP plates after smoothing
Being sent to carries out alkali cleaning in alkaline bath, then is washed by clear water；
Step 2, the CTcP plates after washing are put into electrolytic cell by electrolysis, form electrolytic graining, after electrolysis again
Washed, and be put into oxidation trough and aoxidized, formed oxide layer；
Step 3, will obtain the CTcP plates of oxide layer again by carrying out ink-receptive process after washing after oxidation, wash laggard
Row drying, is then coated and secondary drying again, sets photosensitive layer；
Step 4, the CTcP plates that step 3 is obtained apply up-protective layer；
Step 5, the CTcP plates that step 4 is obtained are removed air guide particle manipulation, obtain air guiding layer；
Step 6, the CTcP plates obtained after finally the 4th time is dried are tested, shear and packed, finished product.
The number of times being electrolysed in described step two is 3 times.
The number of times washed in described step three is 4 times.
The membrane left rate 88-91% being coated in described step three.
Need to carry out a real-time detection per half an hour when being dried in described step three.
The gross thickness of described photosensitive layer is 2.4g/cm2。
Photosensitive layer coated on both sides has binder, and the two sides of photosensitive layer is tight with hydrophilic layer and protective layer respectively by binder
Cohere.
Beneficial effect：Compared with prior art, its advantage is the present invention：
1st, present invention reduces time for exposure and imaging time, be in turn ensure that while improve the time for exposing and being imaged
The press resistance rate high of plate, while in turn ensure that high-quality picture and text output.The present invention does not use the film in preparation process, this
Sample can improve efficiency 60%, and due to eliminating film and its image displaying function, reducing examination print waste paper, ink, fountain solution makes
Consumption, improves the utilization rate of printing machine and Postpress and Print Finishing, saves print preceding and printing time, personnel cost
Substantially reduce.
2nd, the present invention increased yield rate in preparation process, product is cut out, and improve the accuracy of size, save
About cost, while employing processless CTP technology in Project Product production process, it is to avoid the use of a large amount of chemical liquids
And discharge, be conducive to the physical and mental health of employee.
