Abstract
The invention provides cloth for PU synthetic leather and a preparation method thereof. The cloth comprises a yarn layer and a fluffing layer, wherein the fluffing layer is coated with PU slurry; the PU slurry is prepared from, by weight, 80-100 parts of wet polyurethane resin, 70-100 parts of organic solvent, 10-35 parts of filler and 6-12 parts of penetrant. According to the preparation method, the fluffing layer of the cloth is directly coated with the PU slurry, the cloth is put into a solidification tank for solidification and then washed, water in the washed cloth is squeezed through a pressing wheel, and then the cloth is dried, cooled and rolled. According to the cloth, the PU slurry permeates into the fluffing layer, the fluffing layer is filled fully like leather, original soft cloth fluff gaps are filled up, and the filling layer is provided with a large number of air holes according to the principle of the wet process.
Description
Technical field
The invention belongs to PU technical field of synthetic leather, be specifically related to cloth material of a kind of PU use for synthetic leather and preparation method thereof.
Background technology
Synthetic Leather is generally made up of polyurethane dry method surface layer, polyurethane wet middle level and cloth material three-decker.The synthetic leather of common manufacture, although the similar corium of superficial makings, in feel, has plentiful, solid unlike corium, and band has the feel of a resiliency.It just looks like the oranges and tangerines pinching cotton that traditional PU synthetic leather is pinched, full not substantial.Inside traditional synthetic leather production technology, cloth material is after extruding washing, at the boiling hot cloth wheel of 160 ~ 180 DEG C, carry out dry, and control the humidity of cloth material, then on cloth, apply PU slurry, enter coagulating basin and solidify, by washing by DMF (dimethyl formamide) wash-out, extruded by the moisture of product through pinch roller, the baking oven entering 140 ~ 160 DEG C is dried again, and cooling rolling cost finished product is for subsequent use.Through washing, after coating, the feel of semi-finished product (i.e. cloth material) is as one piece of hardboard.This is because cloth material is after the fluffing of cloth factory, cloth gross density is low, through washing, owing to compressing and washing by running roller, has been flattened by cloth hair lower for original density ratio, and make cloth gross density high, the gap between cloth hair is little.Further, traditional washing and pressing technique cause PU slurry to apply permeability reduction.Wash the dry humidity be originally to control in cloth material, general cloth material is after this step, control when the humidity of 40%, the permeability of PU slurry is best, the thickness of infiltration only has 0.1 millimeter, dry energy consumption more further to increase, the highest permeability can only reach 0.15 ~ 0.2 millimeter.
Summary of the invention
For solving the problem of the resiliency feel difference of existing synthetic leather, the present invention proposes a kind of cloth material of PU use for synthetic leather, this cloth material PU slurry penetration is to playing batt, form the plentiful filling being similar to leather effect, by originally soft cloth hair fill gaps, and by the principle of wet processing, make packed layer have a large amount of air-vents.
Technical scheme of the present invention is achieved in that
A kind of cloth material of PU use for synthetic leather, described cloth material comprises thread layers and plays batt, described batt applied atop has PU slurry, calculate according to parts by weight, described PU slurry comprises following component composition: the wet polyurethane resin of 80 ~ 100 parts, the organic solvent of 70 ~ 100 parts, the stuffing of 10 ~ 35 parts, the bleeding agent of 6 ~ 12 parts.
Further, the thickness of described batt account for the thickness of described cloth material 50% and more than.
Further, described organic solvent is selected from one or more of dimethyl formamide, ethyl acetate and butyl acetate.
Further, described wet polyurethane resin is the solvent type polyurethane resin of molecular weight between 100,000 ~ 400,000.
Further, described filler is selected from calcium carbonate, lignocellulose or diatomite, and described bleeding agent is selected from polyether polyester modified organic silicon oxygen alkane or alkyl-modified organosiloxane.
Further, described polyether polyester modified organic silicon oxygen alkane is polyether-modified dimethyl silicone polymer.
The preparation method of PU slurry is: the bleeding agent first taking the wet polyurethane resin of 80 ~ 100 parts, the organic solvent of 70 ~ 100 parts, the stuffing of 10 ~ 35 parts and 6 ~ 12 parts, then mixes.
Bleeding agent mainly improves the seepage velocity of slurry, and osmotic evenness.
Another object of the present invention is to provide a kind of preparation method of cloth material of PU use for synthetic leather, comprises the following steps:
Directly apply PU slurry rising above batt of cloth material, then enter coagulating basin and solidify, then wash, and then through pinch roller, the moisture in the cloth material after washing is extruded, and then dry, then cool rolling.
Further, PU slurry according to the viscosity of production line speed control built in 4000 ~ 10000CPS, and is done to adjust coating thickness 0.8 ~ 1.1mm at any time.
The cloth material of the PU use for synthetic leather that the present invention prepares can continue to apply common wet method layer in thread layers in thread layers again by conventional wet technique as required, also this step can be skipped, enter next step, mill skin is carried out to the batt that rises after coating, makes the back side of product attractive in appearance smooth.
The cloth material of PU use for synthetic leather the present invention prepared carries out common dry process production line and carries out dry method veneer transfer membrane, that is:
Coating dry method surface layer slurry in release liners, enter 120 ~ 130 DEG C of baking ovens to dry, apply the dry method tack coat slurry of the second layer again, enter 90 ~ 100 DEG C of baking ovens, part organic solvent evaporation, then use laminating wheel that PU facial mask and above-mentioned semi-finished product are carried out compound, produce the PU synthetic leather product being rich in lines, corium feel.
Beneficial effect of the present invention:
1, the cloth material of PU use for synthetic leather of the present invention, PU slurry penetration, to playing a batt, is formed and is similar to the plentiful filling of leather effect, by originally soft cloth hair fill gaps, and by the principle of wet processing, makes packed layer have a large amount of air-vents.
2, the cloth material preparation of PU use for synthetic leather of the present invention eliminates washing cloth of conventional wet technique, and controls the step of the humidity of cloth by scalding wheel, directly uses the coating of dry cloth.Have two reasonable effects like this, the impact that the thickness of first cloth material can not be plated, same cloth material thickness is thicker through process of the present invention and the process through traditional handicraft.It two is that feel is then full, and soft, the feel that there will not be traditional handicraft to cause is as one piece of hardboard.
