Abstract
The invention relates to embossed synthetic leather and a preparation method of the embossed synthetic leather. The embossed synthetic leather comprises a base cloth layer; an aqueous PU (polyurethane) foaming layer is coated on the base cloth layer, and the aqueous PU foaming layer is directly embossed to form an embossed layer. The preparation method of the embossed synthetic leather comprises the steps of: preparing slurry, feeding the slurry into a foaming machine and determining size of a required foam hole by adjusting the ratio of the slurry and air inflow, then feeding base cloth into the foaming machine, finishing processing of bass by procedures such as warming, ironing, loading material, feeding into an oven and the like, finally directly embossing on the surface of the discharged synthetic leather out of the oven, enabling the synthetic leather to enter the oven again, and performing cold pressing on the synthetic leather and discharging the synthetic leather from the oven. The embossed synthetic leather manufactured according to the method disclosed by the invention is good in air permeability, good in withdrawing resistance without yellowing, good in resistance to ultraviolet light without aging and mildewing, high in hydrolysis resistance, hardy twisting resistance and abrasive resistance, simple and clear in manufacturing technology, and obvious in energy conservation and consumption reduction, and the fire resistance can be up to advanced international standards.
Description
Technical field
The present invention relates to a kind of synthetic leather and manufacturing approach thereof, be specifically related to a kind of embossing synthetic leather and manufacturing approach thereof.
Background technology
At present, the synthetic leather product becomes following fashion trend gradually, and synthetic leather has been widely used in products such as producing case and bag, clothes, footwear, car interior trim.In the manufacture process of known artificial synthetic leather no matter the manufacturing of base material or musculus cutaneus all used a large amount of solvents; It can cause serious environmental to pollute; Use like the wet type synthetic leather and to contain dimethyl formamide (being called for short DMF) in the solvent, can absorb or can cause poisoning, for by the poison control centre of tubulation via skin by the lung suction; According to stipulating that factory must be provided with the equipment of gas collection and utilization washing and exhaust-gas treatment; Factory and government also must monitor and write down its processing procedure at any time, so its waste water and treatment of waste gas quite waste time and energy, careless slightlyly will cause serious pollution effect.
The manufacture process of the synthetic leather of another kind of dry type is to utilize resin-coated method; The butanone of its use (being called for short MEK) can cause the acute toxic hepatitis of human body; And xylenes has highly combustibility; Can be lighted by heat, spark, flame easily, very easily produce fire, all can pollute air, water.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome deficiency of the prior art the embossing synthetic leather and the manufacturing approach of a kind of good permeability is provided, anti-extractable is good, xanthochromia, UV resistant illumination are aging, manufacturing process is simple and clear, saving energy and reduce the cost.
Technical scheme: embossing synthetic leather of the present invention, comprise base cloth layer, on said base cloth layer, apply the aqueous PU foam layer, and direct embossing forms embossed layer on said aqueous PU foam layer.
Said aqueous PU foam layer is to be laid on the said base cloth layer through cylinder.
The manufacturing approach of embossing synthetic leather of the present invention,
(1) choosing raw material by weight ratio is: 100 parts of water-based PU resins, water 1-20 part, fiber powder 1-8 part;
(2) said raw material is mixed, normal temperature and pressure stirred 10-50 minute down, joined slurry and accomplished;
(3) the said slurry of joining is dropped into frothing machine, adjust the said inlet amount of slurry and the air inflow of frothing machine of joining, according to volume ratio 1: 1-1: 3, obtain the size of required abscess;
(4) drop into said base cloth layer, this base cloth layer of heating is to 60-100 ℃, and the deep layer material loading is passed through on this base cloth layer surface of plating then again, gets into baking oven at last;
(5) said oven temperature is controlled at 80-130 ℃, speed is decided according to required product thickness, be controlled at 3-12 rice/minute;
(6) direct embossing on outlet synthetic leather surface, and then get into baking oven, control oven temperature be at 120-160 ℃, the outlet of colding pressing at last, according to required product THICKNESS CONTROL speed 5-20 rice/minute.
Beneficial effect: the present invention compared with prior art; Its remarkable advantage is: embossing synthetic leather good permeability, anti-extractable be good, not xanthochromia, UV resistant illumination do not wear out, do not go mouldy, fire-retardant reach international advanced standard, hydrolysis, cold-resistant tortuous, wearability is high, manufacturing process is simple and clear, obviously energy-saving and cost-reducing.
