Abstract

The utility model provides a paper for water type printing plate paper, which comprises a paper base layer, a water-resistant bottom material layer, a back material layer, zinc oxide, white material, polyvinyl alcohol, and a water type printing layer. The water-resistant bottom material layer and the back material layer are arranged on the upper surface and the lower surface of the paper base layer and are connected with the paper back layer. The zinc oxide, the polyvinyl alcohol the white material which contains porcelain clay, calcium carbonate, and barium sulfate, and the water type printing layer with plus material of urea aldehyde resin are arranged on the bottom material layer. The utility model has the advantages of low cost, the simplification of process, the shortening of plate-making time, and the improvement of work efficiency.

Description

The water-based Paper for printing

The utility model relates to a kind of offset plate paper, particularly be a kind of water-based Paper for printing.

Existing being used in China's hectographic printing is the printing plate rolled tin.The technological process of its hectographic printing is to need through cleaning glass, be coated with light-sensitive surface on the printing plate rolled tin, take a picture and handle, and colour-separation drafting is proofreaied and correct, and sample, last machine printing are pressed in printing down.Technological process is long, and complicated, and hand labour is many, and labour intensity is also big, thereby long, time-consuming many, weak point such as cost is high, production efficiency is low of the cycle that exists.

In view of above reason, the purpose of this utility model is in order to provide a kind of cost low, can to simplify working process, shorten the plate-making time, increasing work efficiency laborsaving, timesaving water-based Paper for printing.

The purpose of this utility model is achieved like this: paper substrate is arranged in the utility model, place the paper substrate above and below and the anti-water-bed bed of material that is attached thereto, the back of the body bed of material respectively, place the water-based printing layer (referring to Fig. 1) of lining of white material, polyvinyl alcohol, the pollopas of comprising zinc oxide, contain china clay on the initial bed, calcium carbonate, barium sulfate, paper substrate adopts machine-made paper to get final product.

Zinc oxide in the lining in the water-based printing layer, white material are filler, and polyvinyl alcohol, pollopas are adhesive, can replace traditional offset printing liquid medicine with clear water during use.What white material adopted is inorganic filler, better with china clay with regard to its printing character, the space of a whole page cleaning when forme of making prints, not dirty version is also wider to the affine adaptability of plate-making material commonly used.The utility model has adopted the water-based printing layer, and the anti-in addition water-bed bed of material can remedy the wearing and tearing of water-based printing layer.Printing effect is good.The back of the body bed of material adopts filler, can prevent curl, keeps its planarization.

The utility model distortion is little, wear-resistant, does not split not crape, forms the firmly set of oleophilic substance of calligraphy and painting, and the blank parts of not having a calligraphy and painting is not stain by printing ink in printing process.Cost is low, simplifies working process, and shortens the plate-making time, has improved operating efficiency, and is time saving and energy saving.The alternative imported product of the utility model water-based Paper for printing, for country saves a large amount of foreign exchanges, can be country again and save a large amount of non-ferrous metals and other raw material, provide a kind of quick, easy, economic new way to duplicating scientific and technological data, teaching material, file etc., particularly substitute offset printing liquid medicine, meet current environmental consciousness with clear water.The utility model wide accommodation can be used for the method plate-making of static printing, can be used for telex, carbon paper typewriting manifolding again, and ballpoint pen, pencil, drawing prepared Chinese ink, retouching paint, pad-ink etc. are directly made a plate.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is a structure enlarged drawing of the present utility model.

Referring to Fig. 1, the water-based printing layer 1 that contains lining that connects successively, the anti-water-bed bed of material 2, paper substrate 3 are arranged, the back of the body bed of material 4 in the utility model.Fine and smooth and the many concave points of water-based printing laminar surface, its surface area is big, and the oleophilic substance that helps to form calligraphy and painting keeps certain moisture in space of a whole page blank parts firmly and when water-wet is executed in printing.In the water-based printing layer zinc oxide of comprising is arranged, contain the white material of china clay, calcium carbonate, barium sulfate, polyvinyl alcohol, the lining of pollopas etc.In the anti-water-bed bed of material zinc oxide is arranged, white material, polyvinyl alcohol, Ludox etc.Zinc oxide, white material, polyvinyl alcohol, pollopas etc. are arranged in the back of the body bed of material.

Claims (1)

1, water-based Paper for printing, it is characterized in that having in the Paper for printing paper substrate (3), the anti-water-bed bed of material (2) that places the paper substrate above and below respectively and be attached thereto, the back of the body bed of material (4) place the water-based printing layer (1) of lining of white material, polyvinyl alcohol, the pollopas of comprising zinc oxide, contain china clay on the initial bed, calcium carbonate, barium sulfate.
