Abstract
Handled the invention discloses a kind of production method for frivolous synthetic leather of breathing freely, including by the impregnation of warp knit fleece impregnating groove, impregnation material removes；The step of coagulating basin and rinsing bowl progress curing process and washing process, drying and shaping, surface grinding；The impregnation material is made of modified PU resins, solvent dimethylformamide and colorant, the innovative point of the present invention is to add neopelex in modified PU resins, and neopelex is combined with polyurethane material can react and be connected in resin structure.Due to the interface work effect of neopelex, resin foam structure can be improved in process of setting;It can make resin foam structure uniformly and fine and smooth, the film forming of resin is improved into flesh, the speed of resin surface solidification can also be alleviated significantly, form it into the abscess of strip, skin is ground finally by by synthetic leather surface, open the strip perforate of abscess, the passage of finally formed ventilative hydrofuge so that the synthetic leather resin after shaping has excellent ventilative hydrofuge performance.
Description
Technical field
The present invention relates to leather technology field, more particularly to a kind of production method for frivolous synthetic leather of breathing freely.
Background technology
The similar corium performance that synthetic leather is made of synthetic leather base cloth, adhesive layer and surface layer resin it is high-grade artificial synthesized
Leather.Certainly, synthetic leather base cloth has many excellent performances, such as good ventilative and hygroscopicity, excellent physicochemical property,
Such as pulling force, tear resistance, these physical property are already higher than corium, but synthetic leather base cloth is after surface laminating process is carried out, first
The performance of first air-moisture-permeable just exhausts, secondly because of surface layer and synthetic leather bass integraty is bad causes surface plastic cement sense to be compared
Weight.
The content of the invention
The purpose of the present invention is to solve shortcoming existing in the prior art, and the one kind proposed is breathed freely frivolous synthetic leather
Production method.
To achieve these goals, present invention employs following technical solution：A kind of producer for frivolous synthetic leather of breathing freely
Method, it is characterised in that comprise the following steps：
S1：The warp knit fleece of grammes per square metre 325-355g/m2 is passed through into impregnating groove, the impregnating groove with the linear velocity of 10-12m/min
It is interior to expect equipped with the impregnation material that viscosity is 100-150cps, the impregnation by modified PU resins, solvent dimethylformamide and colorant
Composition, its weight ratio are 100：200：5 modification PU resins：Solvent dimethylformamide：Colorant, the modified PU resins include
The raw material composition of following weight percentage:The polyurethane material 8%- synthesized by isocyanates with polyalcohol and its compounding aid
10%；Polyol mixture 17%-22%；Neopelex 0.4%-0.9%；Chain extender 2.2%-
3.7%；Solvent dimethylformamide 58%-72%；
S2：The warp knit fleece that impregnating groove is come out is by a coating head for being equipped with 1.3-1.5mm gaps, by warp knit fleece
Excessive impregnation material removes；
S3：Warp knit fleece after S2 is handled passes sequentially through coagulating basin and rinsing bowl carries out curing process and washing process, leads to
The linear velocity of supersolidification groove is 8-10m/min, and the linear velocity by rinsing bowl is 12-14m/min, and dimethyl is housed in coagulating basin
Formyl amine aqueous solution, mass concentration 25-30%, 24-30 DEG C of temperature, rinsing bowl is interior to be equipped with clear water, 28-32 DEG C of temperature；
S4：Warp knit fleece after S3 is handled carries out drying and shaping under the conditions of being 120-140 DEG C in temperature and semi-finished product is made；
S5：Semi-finished product made from S4 are passed through into the decorticating mill equipped with sand paper and carry out surface grinding, are got product.
It is further improved to be：The polyol mixture is more by mercaptoethanol, epoxychloropropane and polyethylene glycol
First alcohol is with any mixing ratio carries out more alcoholization reactions in alkaline solution and obtains.
It is further improved to be：The chain extender is 4 one butanediols (BDO), 1,6 one hexylene glycols, glycerine, trihydroxy methyl third
Alkane, diethylene glycol (DEG) (DEG), triethylene glycol, neopentyl glycol (NPG), sorbierite, diethylaminoethanol (DEAE) it is one or two kinds of with
On the mixture that is mixed with any mixing ratio.
It is further improved to be：The modified PU resins are prepared in accordance with the following steps：
1）, by above-mentioned 17%-22% polyols mixture, solvent dimethylformamide 58%-72% and 0.4%-
0.9% neopelex and 1.1%-1.95% chain extenders are added separately in reaction kettle in order, are mixed 25
~30 minutes, and control 30~60 DEG C of temperature；
2）The polyurethane material of above-mentioned weight 8%-10% is thrown to reaction kettle in batches, and the temperature of stringent control reaction system is small
In 100 DEG C；After viscosity reaches setting value, remaining 1.1%-1.95% chain extenders and polyurethane material are added, the reaction was continued,

Test data
One piece of leather produced using the embodiment of the present invention 1, embodiment 2, embodiment 3 and common leather are respectively taken, marks A respectively
Group, B groups and C groups and D groups, four block leathers are the circular leather that radius is 5cm, and it is 3cm plastic cups to take two rim of a cup radiuses, mouth
Counterpart is placed, and the plastic cup of top is connected by gas-guide tube with scavenger fan output terminal, and the plastics cup sidewall of lower section is provided with radius
The circular hole of 1cm, for being vented, places the pressure gauge of same specification in two plastics, then respectively by A groups, B groups, C groups and D groups
In leather be placed between two plastic cup rims of a cup, read the numerical value of two pressure gauges respectively, and calculate pressure difference, data are as follows：
| Top pressure gauge reading（Pa） | Pressure below meter reading（Pa） | Pressure difference（Pa） | |
| A groups | 600 | 325 | 275 |
| B groups | 602 | 427 | 175 |
| C groups | 601 | 400 | 225 |
