Abstract

The utility model relates to aqueous-based polyurethane (PU) synthetic leather, which comprises a base cloth layer. The base cloth layer is covered by an aqueous-based PU foaming layer to be processed into Base, and then various required secondary processing is conducted on the Base to form various synthetic leather products. The aqueous-base PU synthetic leather is good in air permeability and pump resistance, free of yellowing, able to bear ultraviolet ray illumination, free of aging and mildew, resistant to hydrolysis, good in resistance to low temperature and flexibility, high in abrasive resistance, simple and clear in manufacturing process and remarkable in energy saving and consumption reducing, and inflaming retarding of the aqueous-base PU synthetic leather achieves advanced international standards.

Description

Water-based PU synthetic leather

Technical field

The utility model relates to synthetic leather, is specifically related to water-based PU synthetic leather.

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, as containing dimethyl formamide (being called for short DMF) in the wet type synthetic leather use solvent, can can cause poisoning via the skin absorption or by the lung suction, for by the poison control centre of tubulation, 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 dimethylbenzene 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 purpose of this utility model is in order to overcome deficiency of the prior art, provides multiple good permeability, anti-extractable good, aging, the energy-saving and cost-reducing synthetic leather of xanthochromia, UV resistant illumination not.

Technical scheme: the utility model has been made such water-based PU synthetic leather, comprises base cloth layer, applies the aqueous PU foam layer on described base cloth layer, and both are combined into bass;

Described water-based PU synthetic leather comprises base cloth layer, applies the aqueous PU foam layer on described base cloth layer, and both are combined into bass, are provided with printed layer on described bass, are processed to form the stamp synthetic leather;

Described water-based PU synthetic leather comprises base cloth layer, applies the aqueous PU foam layer on described base cloth layer, and both are combined into bass, are provided with embossed layer on described bass, are processed to form the embossing synthetic leather;

Described water-based PU synthetic leather comprises base cloth layer, applies the aqueous PU foam layer on described base cloth layer, and both are combined into bass, are provided with on described bass and rub lamina, are processed to form and rub the line synthetic leather;

Described water-based PU synthetic leather, comprise base cloth layer, on described base cloth layer, apply the aqueous PU foam layer, both are combined into bass, on described bass, lay the aqueous PU foam layer by release liners, be processed to form flower-pattern layer, and on described flower-pattern layer, directly rub line formation and rub lamina, be processed to form pattern synthetic leather;

Described water-based PU synthetic leather comprises base cloth layer, applies the aqueous PU foam layer on described base cloth layer, and both are combined into bass, are provided with the sanding layer on described bass, are processed to form the sanding synthetic leather;

Described water-based PU synthetic leather comprises base cloth layer, applies the aqueous PU foam layer on described base cloth layer, and both are combined into bass, are provided with cashmere-planted layer at described bass reverse side, are processed to form the flocking synthetic leather;

Described water-based PU synthetic leather, described aqueous PU foam layer are laid in by cylinder on the described base cloth layer.

Beneficial effect: the utility model compared with prior art, its remarkable advantage is: 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.
