In the technique scheme, the preparation technology of papery watertight composition is: select for use the needle slurry to add water, with the beater making beating, it is standby to put into stock tank; Reuse broad-leaved slurry, add water, with the beater making beating, also put into stock tank, after two kinds of slurries mix in stock tank, add super-fine active calcium carbide, the plain waterproofing agent of fluorine, fully stir a period of time, manufacture paper with pulp into semi-finished product paper with fourdrinier then, semi-finished product paper again through the aqueous solution drill traverse of the plain waterproofing agent of fluorine wet after, after the oven dry of coating machine drying cylinder becomes the waterproof paper finished product.

It is the existing following shortcoming of single ply waterproofing paper that this utility model has solved the prior art watertight composition:

Because require the long-time waterproof of waterproof paper of watertight composition, it is thicker that the requirement paper is oozed in its resistance to compression, wood fiber density is big, generally reaches 26-32 to restrain/every square metre, makes waterproof paper more crisp, weak strength, and:

1) waterproof paper is crumpled very big sound;

2) edge ftracture easily, damaged, intensity difference;

3) and contact skin, comfortableness is poor.

Bottom of the present utility model adopts the double-decker of papery watertight composition+papery bottom, has solved the problem that above-mentioned prior art exists.Papery bottom of the present utility model is selected a kind of special paper on the market for use, and its grammes per square metre is covered with many trickle holes above every square metre of 14-16 gram, and suppleness, wet strength are all stronger, remedy the shortcoming that above-mentioned prior art exists with this.

The utility model has the advantages of and be:

1) because bottom adopts the double-decker of papery watertight composition+papery bottom, the papery bottom is not done water-proofing treatment, its intensity of double-deck bottom has increased, the wood fiber of the papery bottom of the water vapour that sees through by waterproof paper during use below can be not moistening, and because above be covered with many holes, water vapour can be discharged from hole, so the papery bottom still keeps dry, intensity can not reduce, and has highly-breathable;

2) because bottom adopts double-decker, pliability, suppleness characteristic that its papery bottom itself is had, with the papery watertight composition bonding after, can not send the sound during use, the indecency and embarrassment in avoiding using;

3) characteristic of papery bottom strengthens product edge suppleness, and not easy to crack, the baby uses also more safe and reliable, comfortable;

4) surface layer of the present utility model adopts textile surface layer, and textile material is a pure natural plant fiber, does not contain Chemical fiber component, papery watertight composition and papery bottom are that pure wood pulp is made, and also are pure plant fiber, do not contain Chemical fiber component, therefore can both in the Nature, degrade, can not produce environmental pollution;

5) the newly-increased more soft papery bottom of this utility model, though solved owing to the thickness of waterproof paper, edge cracking that hardness brings, problem such as the sound is arranged, but examining and filtering this utility model bottom is that double-decker and waterproof paper itself also have certain rigidity, may cause that like this both sides hardness increases, and in use causes the discomfort of user medial thigh skin easily.For this reason, this utility model will design narrowlyer slightly than textile surface layer and papery bottom dual-side as the width of its dual-side of waterproof paper of watertight composition, and wideer slightly than water accepting layer.Like this, just make the dual-side that contacts with the baby along partly having textile surface layer and extremely softish papery bottom bonding, dual-side is along very soft, and the edge contacts with baby's medial thigh skin and just do not have sense of discomfort.

6) layer structure of this utility model uniqueness can be widely used in baby diaper, diaper, adult nursing sanitary belt, medical pad, list, pet pads, woman with fields such as nursing towels.

The accompanying drawing marking explanation:

1---surface layer 2---water accepting layer 3---papery watertight composition

4---papery bottom 5---adhesive-layer

The specific embodiment:

Referring to Fig. 1, this high papery baby diaper of breathing freely is made up of surface layer 1, water accepting layer 2 and bottom, and bottom adopts papery watertight composition 3 to add the double-decker of papery bottom 4, between each layer by adhesive-layer 5 connections.Papery watertight composition 3 dual-side width are less than surface layer 1 or papery bottom 4 dual-side width, greater than water accepting layer 2 dual-side width.Be furnished with some trickle air-vents on the papery bottom, surface layer adopts textile material surface layer.Water accepting layer adopts the fine hair wood pulp.

The preparation technology embodiment of papery watertight composition is as follows:

1, selects needle slurry 560-600 kilogram (over dry) for use, add 1500 kg of water, with the mill beater 85-90 degree of pulling an oar, it is standby to put into stock tank, reuse 440-480 kilogram broad-leaved slurry, over dry, add 1200 kg of water, with the mill beater 34-39 degree of pulling an oar, put into stock tank, in the stock tank that mixes two kinds of slurries, add the super-fine active calcium carbide (for conventional papermaking filler) of 160-180 kilogram, add the plain waterproofing agent of 15-20 kilogram fluorine again and fully stirred 1 hour, the fourdrinier of reuse 1880 is manufactured paper with pulp into semi-finished product paper.2, semi-finished product paper is through the coating machine coating, and the raw material of coating is the aqueous solution (1 to 12) of the plain waterproofing agent of fluorine, soaks through the drying cylinder oven dry, and dryer temperature is controlled at 100-169 degree best results, makes finished product waterproof, grease proofing biological antibiotic paper.The waterproof effect that fluorine class material produces is that everybody generally acknowledges.

Waterproof, grease proofing mechanism: utilize water and oil surface tension waterproof, grease proofing, the surface tension of (when temperature 20 is spent) water is 72,8 under given conditions.The critical surface tension force of Plant fiber's cellulose fiber is 200 for (vcdyne/cm).Its critical surface tension is greater than water or oil surface tension, thereby can be by water or oil immersion profit.

Its critical surface tension of paper is lower than water and oil surface tension after waterproof, the anti-oil processing.After the processing, the interfacial tension of fabric face is low more, and then to refuse water, oil repellent good more.

Paper waterproof, anti-oil processing are a kind of process for treating surface, be to realize synchronously, promptly use chemicals (realizing) evenly to be coated with at fiber surface by the perfluor alkyl ethide acrylic polymer, the water and oil repellant layer that alkyl outwards aligns and play the effect of waterproof and oilproof, make it to have low boundary (table) surface tension, cause water and oil can not its surface of moistening.And can make paper keep original porosity, suppleness, air permeability, outward appearance and wet strength thereof.

Common tissue paper does not reach the effect of long-time waterproof and oilproof because paper sheet thickness is all smaller, and void ratio is bigger yet by waterproof, anti-oil processing.And the combination that this utility model utilizes needle slurry and broad-leaved to starch two kinds of fibers in the time of the manufacturing paper with pulp of body paper, add again as super-fine active calcium carbide and repair the fiber holes gap structure as filler (can improve the paper interfacial structure), the paper hole is diminished, strengthen the density and the intensity of paper.Do waterproof again, prevent that oil processing could realize long-time waterproof and oilproof.

Ventilative principle: (average grain 0.02～0.04um) is as filler to add super-fine active calcium carbide in paper making, make between high polymer and the filler and form hole, these holes are less than 2um, can stop water droplet (average diameter 100um) but can allow water vapour molecule (average diameter 0.0004) pass through, reach waterproof and breathable.
