The surface layer slurry and base pastes mixing can also include whipping process, and the stirring can make the surface layer
It is uniformly dispersed with base pastes, the stirring can carry out in blender.
Refering to fig. 1 to Fig. 2, the present invention also provides a kind of method for making the aqueous polyurethane waterproof cloth leather, packets
The step of including S1 to S4:
S1: a release paper is provided；S2: it is applied in the release paper and scrapes the surface layer slurry and dry to form the face
Layer；S3: painting scrapes the base pastes and forms the bottom in the surface layer；S4: it is bonded a base fabric on the bottom and dries
It is dry to be removed from office with obtaining the waterproof cloth.
In step sl, the release paper can cling slurry, but both be easy to make to separate, not with resin system
Reaction or pollution resin system are learned, in environment temperature and humidity variation, the length and width of release paper should all be remained unchanged, with
To exempt to cause release paper to wrinkle and to hang painting slurry fold, its elongation should be consistent with fiber after release paper is towed,
It is in one embodiment, described release to prevent the slurry from causing torsional deformation since drawing-off is asynchronous during the preparation process
Paper can be silicone oil paper.
It can also include vacuumize process after standing the surface layer and base pastes before carrying out step S2 and S3,
The time of repose can be 12-24 hours, such as 24 hours, the bubble in the slurry can be made gradually to suspend after standing
On the surface of the slurry, the subsequent efficiency vacuumized is improved, described vacuumize can be evacuated to the pulp surface without obvious
Stop when foaming phenomena, slurry abscess can be made more careful after standing vacuumize process.
In step S2 and S3, the surface layer slurry painting scrapes gap and can be 0.1-0.13mm, i.e. 10-13 item, such as 10
Item, 13, it can be 10-13 item that gap is scraped in base pastes painting, such as 10,13.The painting applies knife during scraping
Gap is scraped in painting can control the thickness of the waterproof cloth leather, usually be divided into 100 for one millimeter in mechanical dimension's metering
Part, length unit representated by portion therein is known as one, and one is 0.01mm, applied in the present invention scrape 1=1, gap=
0.01mm, gap is scraped in painting can control the thickness for applying and scraping, and can apply platform by electric automatization in the present invention and be adjusted control,
Input needs to apply the thickness scraped, and the painting knife automatic lifting for applying platform adjusts to the painting of needs and scrapes gap, and the cloth removes from office thickness
It can be set according to customer demand.
In step s 2, the surface layer slurry, which applies the post-baking temperature scraped, can be 120 DEG C -130 DEG C, such as 120 DEG C,
130℃。
In step s 4, the post-baking temperature of the bottom fitting base fabric can be 120 DEG C -130 DEG C, such as 120 DEG C,
130℃。
In step S2 and S4, the drying can be heated-air drying drying, using from the two sides up and down of the release paper
The mode of blowing heating carries out, such as can be in baking oven or drying room and carry out, and the length of the baking oven can be 10-20m,
Such as 15m, wherein the release paper carries out heated-air drying in the state of being in horizontal movement, the horizontal movement speed be can be
10-25m/min, such as 15m/min.After the drying, cooling treatment can also be carried out, the cooling procedure can be in cooling
It is carried out on roller.
In one embodiment, the waterproof cloth leather obtained can also be carried out stripping the post-processing such as release paper, bundling
To form finished product, it is described strip release paper, bundling operation can carry out on separate roller.
The solution of the present invention is described further combined with specific embodiments below.
