Description
Technical field
The present invention relates to leather field, relate in particular to the preparation method of the large bottom material of a kind of latex.
Background technology
In the ox-hide course of processing, can produce a large amount of scurf, generally process by burning, but burning can produce flue gas, has contaminative; And directly bury, because it cannot be degraded, also easily produce and pollute.
For this reason, someone proposes to recycle the scurf exploitation large end of latex.The so-called large end of latex,, refer to that a kind of application ox-hide wet blue bits are main raw material(s), the novel material obtaining after process for processing, and its wear resistance is better than true ox-hide, and the physicalies such as resistance to complications, tensile strength and true ox-hide compare favourably.The large end of this latex, is of many uses, except as footwear use, can also serve as the finishing material such as floor and use.
At present, conventional latex product preparation method comprises: selection, pulverize fine grinding, mix and blend, vacuum hydro-extraction, roll forming, plate press-dehydrating, drying and other steps; Described roll forming comprises doffer water squeezing and swift water squeezing two steps.But existing latex product preparation method is only better to producing the latex product effect of thickness below 2.5 millimeters; For the large bottom material of latex, because its hide fiber is tiny, thickness is larger, and the difficult dehydration of existing technique especially easily damages material structure when doffer roll forming; Cause material tensile strength low, the serious quality problems such as easy to crack, scrap material.In addition, traditional plate press-dehydrating technique, is generally voltage stabilizing 280 bar, approximately 60 seconds clamping times.Adopt this voltage stabilizing technique that the large bottom material density of latex is increased, surface has formed layer protecting film, and when the large bottom material process of latex baking oven, the moisture in material is just difficult for coming out.
In view of this, be very necessary to develop a kind of roll forming effective, be convenient to the large bottom material production technique of latex of drying and dehydrating.
Summary of the invention
The defect existing for prior art, the object of the invention is to, and develops a kind of good forming effect, the preparation method of the fast large bottom material of latex of dewatered drying.
For reaching above object, the present invention adopts following technical scheme.
A preparation method for the large bottom material of latex, is characterized in that, comprising:
The first step: skin is broken selected;
Second step, pulverizes, and to the broken further pulverizing of the skin after selected, and pulverizes while the stirring that adds water, until the broken weight of skin accounts between the 3.5-4.0% of total proportion;
The 3rd step, fine grinding, to broken the milling of skin after pulverizing, until the broken particle fiber that becomes 1mm-2mm of skin;
The 4th step, mix and blend, stirs broken the skin after the fine grinding agitator that adds, and stirs while add tannin extract, lipid material and staining agent, in whole whipping process, maintains the temperature between 28 ℃-35 ℃;
The 5th step, bonding and vacuum hydro-extraction first adds glue in the broken material of the good skin of mix and blend, makes the pH value of the broken material of skin between 4-6, then dewaters under-0.04Mpa vacuum at relative vacuum degree;
The 6th step, leather compression moulding, comprising: dull and stereotyped water squeezing and two operating processes of large roller roll extrusion water squeezing;
The 7th step, second dehydration, comprises altogether: travelling belt dehydration, felt dehydration and three flow processs of plate press-dehydrating;
The 8th step, dry, the leather of the mode that adopts steam drying after to moulding is further dry, and here, the temperature of described steam is between 150 ℃-200 ℃;
The 9th step, product finishing, revises the leather of compression moulding, obtains finished product;
The tenth step, packing warehouse-in.
As with improvement, described second dehydration adopts the mode of plate extrusion water; The pressure of this plate extrusion water adopts the progressively mode of pressurization, that is, not supercharging under 10 seconds inherent standard barometric points, is then pressurized to 180 bar in 10 seconds gradually, more then in 20 seconds, keeps the pressure of 180 bar constant, release in last 9 seconds.
As with improvement, after the 8th step is dry, be also provided with radiating and cooling step.
As with improvement, described the 4th step, the formula that mix and blend adopts is: scurf 500KG, glue 205KG, sodium bicarbonate 25KG, tannin extract 25KG, defoamer 15KG, stablizer 6KG, resin 50KG.
As with improvement, described the 9th step product finishing comprises: the first small step, finishing corner; The second small step, linear measure; The 3rd small step, flattens; The 4th small step, mill skin; The 5th small step, bundling, section; The 6th small step, product examine.
Adopt the large bottom material preparation method of latex provided by the invention, there is following beneficial effect.
One,, in leather compression moulding process, adopt dull and stereotyped water squeezing to replace traditional doffer water squeezing; After transformation, effectively provide dehydrating effect like this, even in the not good situation of a upper operation dehydration, also can not destroy material.
Two, in the time of second dehydration, adopt the mode of progressively pressurization to replace traditional lasting voltage regulation way, not only making the second dehydration time die-off by original 60 seconds is 49 seconds, shorten process period, and the large bottom material surface density that the dewatering type of progressively pressurization has effectively avoided traditional quick boosting mode to cause is large, the difficult defect of dewatering; The large bottom material of latex is more easily dried in follow-up drying operation, greatly shortened the whole process period of the large bottom material of latex, production efficiency significantly promotes.
Three, formula is improved, effectively improved the dehydrating effect of the large bottom material of latex.
Accompanying drawing explanation
Figure 1 shows that the large bottom material preparation flow of latex provided by the invention figure.
