Abstract
A kind of ecological property shoe lining PU removes from office, comprise Ji Bu, tack coat, water-based PU layer, aqueous foaming layer and top finishing layer, Ji Bu is the elastic non-woven cloth be made up of polyethylene layer and polypropylene layer compound, and water-based PU layer is made up of aqueous polyurethane, blowing agent and thickener.The raw material of synthetic leather of the present utility model are renewable, free from environmental pollution in production process and use procedure, can not work the mischief to the healthy and safe of people, and can degrade under field conditions (factors) after discarded, can not cause new pollution to environment.
Description
Technical field
The utility model relates to a kind of shoe lining synthetic leather, is specifically related to a kind of ecological property shoe lining PU and removes from office.
Background technology
Natural leather, also known as corium, is processed by Animal Skin, common are pig leather, ox-hide leather, sheep, horse skin leather etc.The feature of natural leather be soft, ventilative, wear-resisting, intensity is high, has the advantage of high-hygroscopicity and water vapor permeability, but resource-constrained, price and process is polluted heavy, in addition, corium out-of-shape, thickness is very uneven yet, and surface easily exists disability.
Artificial leather synthetic leather can be divided into PVC artificial leather and PU synthetic leather, and because process is not by the restriction of time, raw material, product uniformity is better, fabric width consistent, and being easy to cutting processing, is the good material of alternative natural leather in recent years.Wherein, PVC artificial leather to be mainly coated on fabric base obtained by forms such as solution, suspension, plastisol or films, and advantage is that low price, rich color, decorative pattern are various, shortcoming is that base cloth adhesive fastness is poor, is easy to peel off, and weatherability is poor, feel is stiff, flexibility difference etc.; PU synthetic leather chemically structure, closer to cortex fabric, skin sense is strong, feel good springiness, not easily hardening, become fragile, there is rich color, decorative pattern is various, durability is more of a specified duration advantage simultaneously, cost ratio PVC artificial leather wants high, more cheap than cortex fabric, can effectively replace PVC artificial leather, corium.
Superfine fiber chemical leather is third generation artificial leather, it is that the nonwoven fabric made using superfine fibre is as matrix, there is the microstructure similar to natural leather, mutually twine conjunction by fine collagenous fibres to form, adopt Synthetic Leather aftertreatment technology simultaneously, make the outward appearance similar to natural leather.Microfiber synthetic leather on outward appearance, feel and immanent structure all close to corium, the physical property such as acid-fast alkali-proof, yellowing resistance, peel strength, bursting strength are even better than corium, the industries such as high-grade clothing, shoemaking, sofa furniture, case and bag, decoration can be widely used in.It is higher that superfine fiber chemical leather is faced with production cost in Colour Difference process at present, and energy consumption is large, the problem that the relatively large grade of environmental pollution improvement's difficulty is certain and challenge.
In recent years, ecological functions Synthetic Leather is just with its advantage such as moderate cost, high physical property, multifunctionality, eco-environmental prote, the share of occupying in the application of artificial leather synthetic leather Downstream Market progressively promotes, and progressively substitutes PVC artificial leather, common PU synthetic leather and natural leather article.Ecological functions synthetic leather refers to that product both possessed eco-environmental prote, possesses again various premium properties to meet the synthetic leather product of the various demand of consumer simultaneously.
As the shoe lining of leather shoes, corium easily fades, and pollutes footgear, and artificial leather synthetic leather ventilative and hygroscopicity can be bad, and comfortableness is not high, and superfine fiber chemical leather dyeing course energy consumption is large, can give environment.
Utility model content
For the problems referred to above, the utility model provides a kind of ecological property shoe lining PU and removes from office, its object is to: the shortcoming solving various leather in prior art, a kind of shoe lining leather with fine and smooth sense of touch, ventilative, excellent moisture absorption hydrofuge, the performance such as not fade is provided.
Technical solution of the present utility model:
A kind of ecological property shoe lining PU removes from office, comprise Ji Bu, tack coat, water-based PU layer, aqueous foaming layer and top finishing layer, described Ji Bu is the elastic non-woven cloth be made up of polyethylene layer and polypropylene layer compound, and described water-based PU layer is made up of aqueous polyurethane, blowing agent and thickener.
The foaming structure of described aqueous foaming layer is honeycomb type.
The thickness of described aqueous foaming layer is 0.05mm.
Described tack coat is made up of polyvinyl alcohol.
The thickness of described tack coat is less than 0.03mm.
The beneficial effects of the utility model:
The raw material of synthetic leather of the present utility model are renewable, free from environmental pollution in production process and use procedure, can not work the mischief to the healthy and safe of people, and can degrade under field conditions (factors) after discarded, can not cause new pollution to environment.
Accompanying drawing explanation
Fig. 1: the utility model structural principle schematic diagram.
Wherein: 1 base cloth 2 water-based PU layer 3 aqueous foaming layer 4 tack coat 5 top finishing layer.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further:
As shown in Figure 1, a kind of ecological property shoe lining PU removes from office, comprise base cloth 1, water-based PU layer 2, aqueous foaming layer 3, tack coat 4 and top finishing layer 5, Ji Bu is the elastic non-woven cloth be made up of polyethylene layer and polypropylene layer compound, water-based PU layer is made up of aqueous polyurethane, blowing agent and thickener, and the foaming structure of aqueous foaming layer is honeycomb type, and the thickness of aqueous foaming layer is 0.1mm, tack coat is made up of polyvinyl alcohol, and the thickness of tack coat is less than 0.05mm.
During processing the utility model product, water-based PU layer 2 is coated in release liners, carry out Drying and cooling process, after process for cooling step, aqueous foaming layer 3 is applied with on water-based PU layer, carry out drying and processing, finally apply tack coat 4, be bonded together by roll-in mode and base cloth 1, after super-dry, cooling, utilize stripping off device by finished product synthetic leather and release liners rolling, packaging respectively, become final products.
To sum up, the utility model accomplishes the end in view.
