Abstract
The invention relates to flocking synthetic leather and a manufacturing method thereof. The flocking synthetic leather comprises a basic cloth layer, wherein a water-based PU (Poly Urethane) foaming layer is coated on the front side of the basic cloth layer, and a flocking layer is formed by directly flocking on the back side of the basic cloth layer. The manufacturing method of the flocking synthetic leather comprises the following steps: preparing slurry and putting the slurry into a foaming machine; confirming the size of foamed holes by adjusting the ratio of slurry to air inflow; putting in the basic cloth; finishing the processing for the base by performing the processes of heating and ironing, loading material, feeding into oven, and the like; and lastly, performing flocking treatment on back side of the discharged synthetic leather. The flocking synthetic leather manufactured according to the manufacturing method provided by the invention has the advantages of excellent air permeability, excellent extraction resistance, being free from yellowing, ultraviolet radiation resistance and being free from aging and mildewing, flame retardance reaching international advanced standard, hydrolysis resistance, cold winding resistance and high abrasive resistance. The manufacturing method is simple and clear and the energy-saving and consumption-reducing effects are obvious.
Description
Technical field
The present invention relates to a kind of synthetic leather and manufacturing approach thereof, be specifically related to a kind of flocking 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 flocking 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: flocking synthetic leather of the present invention, comprise base cloth layer, at said base cloth layer front surface coated aqueous PU foam layer, and at the said base cloth layer back side direct flocking forms cashmere-planted layer.
Said aqueous PU foam layer is to be laid on the said base cloth layer through cylinder.
The manufacturing approach of flocking 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 product thickness, be controlled at 3-12 rice/minute;
(6) the outlet synthetic leather is carried out back side flocking and handle the back.
Beneficial effect: the present invention compared with prior art; Its remarkable advantage is: flocking 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.
