Abstract
The invention relates to a printed synthetic leather and a method for manufacturing the printed synthetic leather. The printed synthetic leather comprises a base cloth layer; the base cloth layer is coated with a water PU (polyurethane) foaming layer; and the surface of the water PU (polyurethane) foaming layer is printed directly to form a printed layer. The method for manufacturing the printed synthetic leather comprises the following steps: preparing a slurry; feeding the slurry into a foaming machine; adjusting the proportion of the slurry amount to the air intake to determine the size of needed foam holes; feeding a piece of base cloth, heating to iron, feeding, and putting into a baking oven to finish processing the base cloth; and finally printing directly on the surface of the synthetic leather taken out of the baking oven. The printed synthetic leather manufactured by adopting the method has good breathability and extraction resistance, can resist the irradiation of ultraviolet light, hydrolysis, cold bending and wear, can not become yellow, age and mildew and reaches the international advanced flame resistance standard. The process for manufacturing the printed synthetic leather is simple and has the advantages of saving energy and reducing consumption.
Description
Technical field
The present invention relates to a kind of synthetic leather and manufacturing approach thereof, be specifically related to a kind of stamp 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 cause poisoning, for by the poison control centre of tubulation via skin absorbs or 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 xylene 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 stamp 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 technique is simple and clear, saving energy and reduce the cost.
Technical scheme: stamp synthetic leather of the present invention, comprise base cloth layer, on said base cloth layer, apply the aqueous PU foam layer, and the direct surface stamp forms printed 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 stamp 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) together, normal temperature and pressure stirred 10-50 minute down, joined slurry and accomplished with said raw materials mix;
(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 10-30 rice/minute;
(6) direct printing on outlet synthetic leather surface.
Beneficial effect: the present invention compared with prior art; Its remarkable advantage is: stamp 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, ABRASION RESISTANCE is high, manufacturing technique is simple and clear, obviously energy-saving and cost-reducing.
