Abstract
The present invention relates to a preparation technique of a modified rubber sheet (4). The rubber sheet is processed by a corona discharge plasma under the state of normal pressure in atmosphere, and paint is coated on the surface of the rubber sheet; afterwards, drying is carried out. Equipment used in the present invention comprises a rubber sheet roller (1), a guide roller (3), a conductive body thread (2), an upper scraping roller (6), a lower scraping roller (7), a baking oven (8), a press roll (9), a drive roller (10), a driving belt (11) and an electric motor (12); the outer circle of the guide roller (3) is coated with a layer of dielectrics; the guide roller (3) is a conductive body. The rubber sheet processed by the technique of the present invention is suitable for the writing and the copying of the rubber sheet of a projector, and an ordinary aquosity pen can be used for writing; the writing performance can be kept for a long term, and the rubber sheet can be repeatedly used. The modified rubber sheet can be used for a typesetting system of a computer laser printer.
Description
The present invention is a kind of technology of preparing of modified film, be specially adapted to that projector uses write, duplicate film and Computerized laser type printer composing system.
At present for writing that multiple projector uses, duplicate film, great majority are that the indusrial polyester film is directly cut out and formed, and because of its surface tissue influence, can only could write thereon with special oil pike, and common free ink pen all can not be used, to making the film use that inconvenience be arranged more.Have in the prior art and a kind ofly can write by the use pen, but this function only can be kept and just can disappear in 2～3 months through plasma body simply dealt film.By retrieval with the invention correlation technique JP60～141727 " manufacturing of blur prevention hyalosome ", its technological process is under vacuum state, a kind of plastics are carried out Low Temperature Plasma Treating, then make surperficial saponification, be coated with one deck promoting agent then with highly basic.This technology is different with purpose of the present invention, and is also inequality to the treating processes of process object.
The objective of the invention is under atmospheric normal pressure condition, utilize corona discharge plasma to handle film, be coated with tailor-(made) coating then, make the film modification, not only can write thereon by enough ortho-water pens, and this writing quality can also keep for a long time, and film can be reused.
Special character of the present invention is to adopt under atmospheric normal pressure condition corona discharge plasma technical finesse film then to be coated with tailor-(made) coating, carries out drying then, makes the film surface modification.
Special character of the present invention is that discharge gap voltage is 7～15 kilovolts, the plasma electrically source frequency is 10～500 kilohertzs, and the treatment time is 2～6 seconds, and film at the uniform velocity passes through plasma slab, one deck tailor-(made) coating is executed on the surface then, and is dry under 120 ℃～130 ℃ temperature condition.
Be used for equipment of the present invention, have film roller (1), several guide rollers (3), on scrape roller (6), down scrape roller (7), baking oven (8), pressure roller (9), drive roll (10), pulley belt (11), electric motor (12).Electric motor (12) drives drive roll (10) by pulley belt (11) and rotates, frictional force transmission between pressured roller of film (4) (9) and drive roll (10), its special character are that film (4) is through plasma slab, by tailor-(made) coating (5), pass through baking oven (8) at last.Guide roller (3) is an electrical conductor, and relative with each guide roller (3) should have several electrical conductor silks (2).
Be used for equipment of the present invention, its special character is that the distance between guide roller (3) and electrical conductor silk (2) is adjustable.
Be used for equipment of the present invention, its special character is that the cylindrical of guide roller (3) is surrounded by one deck dielectric medium.
The invention has the advantages that, handle through corona discharge plasma, then surface coated tailor-(made) coating (5), the dry then modified film that obtains can be write by enough ortho-water pens, and this writing quality can keep for a long time, and film is reusable.In addition, the film after the modification can also be used for duplicating, and Computerized laser type printer composing system can obtain the positive of printing down, directly makes a plate, and has significantly reduced operation and cost, and is simple and easy to do, the efficient height, and quality is good.

Embodiment: under atmospheric normal pressure condition, adopt corona discharge plasma to handle film, discharge gap voltage is 11～12 kilovolts, the plasma electrically source frequency is 10～11 kilohertzs, treatment time is 4～5 seconds, film (4) at the uniform velocity passes through plasma slab, (this tailor-(made) coating weight percent is: polyvinyl alcohol 3～5 through tailor-(made) coating (5) coating then, trimethylol melamine 0.3～0.5, alizarin assistant 0.048～0.09, hydrochloric acid 0.0083～0.083, water 94.4～96.64, but normal temperature prolonged preservation use down) enter the far infrared baking oven at last, under 120～130 ℃ of temperature condition, dry.
Be used for equipment of the present invention, have film roller (1), 35～54 electrical conductor silks (2), 7～9 guide rollers (3), on scrape roller (6), down scrape roller (7), baking oven (8), pressure roller (9), drive roll (10), pulley belt (11), electric motor (12).Electric motor (12) drives drive roll (10) by pulley belt (11) and rotates.Film (4) at first passes through plasma slab by the frictional force transmission between drive roll (10) and pressure roller (9), then by tailor-(made) coating (5) coating, enters far infrared baking oven (8) oven dry at last.Guide roller (3) is an electrical conductor, and guide roller (3) is corresponding with electrical conductor silk (2), and distance between the two is adjustable, and the cylindrical of guide roller (3) is surrounded by one deck dielectric medium (13).
Claims (1)
1, a kind of preparation method of modified film, under atmospheric normal pressure condition, adopt corona discharge plasma to handle film, discharge gap voltage is 7～15 kilovolts, the plasma electrically source frequency is 10～500 kilohertzs, film at the uniform velocity passes through plasma slab, surface coated tailor-(made) coating then, and carry out drying, it is characterized in that the tailor-(made) coating weight percent is: polyvinyl alcohol 3～5, trimethylol melamine 0.3～0.5, alizarin assistant 0.048～0.09, hydrochloric acid 0.0083～0.083, water 94.4～96.64, drying temperature are 120～130 ℃.
