Abstract
The utility model discloses novel environment-friendly synthetic leather. The novel environment-friendly synthetic leather comprises a degradable nonwoven fabric layer, a water-based polyurethane foaming layer which is coated on the degradable nonwoven fabric layer and a fluorine-contained water-based polyurethane layer which is transferred and coated on the water-based polyurethane foaming layer in a dry method. Compared with the prior art, the novel environment-friendly synthetic leather has the advantages of environmental protection, no pollution and good mechanical performance.
Description
Technical field
The utility model relates to the artificial leather technical field, is specifically related to a kind of novel environment friendly synthetic leather.
Background technology
Synthetic Leather is similar owing to The Nomenclature Composition and Structure of Complexes and natural leather divide mutually, now has been widely used in the goods such as footwear, bag, clothes.Early the Synthetic Leather that occurs is the solvent borne polyurethane synthetic leather, contains organic solvents such as methylformamide, toluene, MEK, and these solvents produce serious pollution to environment, have stoped development and the application of molten Ji type polyurethane synthetic leather.A lot of aqueous polyurethane synthetic leather have appearred on the existing market, comparison safety, environmental protection owing to the organic solvent that does not contain or contain minute quantity.But the mechanical strengths such as peeling off, tear of existing aqueous polyurethane synthetic leather is not as good as traditional solvent borne polyurethane synthetic leather.Thereby, promote and developing water based polyurethane synthetic leather, must increase its mechanical performance.
The utility model content
The purpose of this utility model is to overcome the defective of above-mentioned prior art, and a kind of novel environment friendly synthetic leather is provided, and this synthetic leather not only has environmental protection, free of contamination advantage, and mechanical performance also approaches with the solvent-borne type synthetic leather.
For achieving the above object, the utility model adopts following technical scheme:
A kind of novel environment friendly synthetic leather is characterized in that: the aqueous polyurethane foaming layer, the dry method that comprise the degradable nonwoven fabrics layer, are coated on the degradable nonwoven fabrics layer shift the fluorine-containing aqueous polyurethane layer that is coated in the aqueous polyurethane foaming layer.
The thickness of described fluorine-containing aqueous polyurethane layer is 1mm.
The thickness of described aqueous polyurethane foaming layer is 0.5～1mm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model selects for use degradable nonwoven fabrics as the base material of synthetic leather, and the aqueous polyurethane foaming layer of Tu Fuing, fluorine-containing aqueous polyurethane layer all do not contain organic solvent, environment-protecting asepsis thereon; And, adopt fluorine-containing aqueous polyurethane layer as the facial ornament layer of synthetic leather, and shifting cladding process by dry method makes, can make the surface of synthetic leather have good mechanical strengths such as peeling off, tear, the performance of each side such as wear-resisting, anti-solvent, hydrolysis and traditional solvent borne polyurethane synthesising leather performance are close.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of novel environment friendly synthetic leather, aqueous polyurethane foaming layer 2, dry method that it comprises degradable nonwoven fabrics layer 1, be coated on the degradable nonwoven fabrics layer 1 shift the fluorine-containing aqueous polyurethane layer 3 that is coated in the aqueous polyurethane foaming layer 2.Particularly, described degradable nonwoven fabrics layer 1 is to adopt string to make nonwoven fabric.
As preferred version of the present utility model, for strengthening the mechanical performance of synthetic leather, the thickness of described fluorine-containing aqueous polyurethane layer 3 is 1mm, and the thickness of described aqueous polyurethane foaming layer 2 is 0.5～1mm.
Above-mentioned embodiment only is preferred embodiment of the present utility model; can not limit the scope of the utility model protection with this, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
