Background technology
At present, synthetic leather product becomes following popular trend gradually, and synthetic leather has been widely used in producing in the products such as case and bag, clothes, footwear, furniture.But simultaneously along with the raising of socioeconomic development and people's living standard, people require also more and more higher for the added value of these necessity for life.
Traditional synthetic leather is all at wet method bass surface laminating one deck dry coating, road process after coating surface carries out, make surface give the texture of skin, but the third dimension of the decorative pattern on its surface is poor, gauffer is larger, without pendency sense, overall sense of touch differs greatly compared with corium.
Utility model content
Technical problem to be solved in the utility model is exactly the deficiency overcoming existing product, a kind of Ecology Leather of high corium content is provided, not only apparently exactly likes corium, also there is texture and the comfort level of corium, physical and mechanical properties is obviously better than corium, and price is starkly lower than corium.
For realizing above-mentioned object, the utility model provides following technical scheme:
An Ecology Leather for high corium content, described Ecology Leather comprises base cloth layer, and the upper surface of described base cloth layer is coated with wet method bass coating, and described wet method bass coating is fitted with dry coating by polyurethane resin; The lower surface of described base cloth layer is bonded with corium powder cloth layer, and described corium powder cloth layer is bonded by the corium bisque of corium powder pressing and fibrous face to form, and the described fibrous face of corium powder cloth layer and the lower surface of base cloth layer are bonded into one.
Further, the fibrous face of described corium powder cloth layer is bonded into one by the lower surface of polyurethane resin and base cloth layer.
In order to the outward appearance and the sense of touch that make Ecology Leather have corium, the thickness of described corium powder cloth layer is 0.8-1.0mm; The mass percent of corium powder is contained for being not less than 40% in described Ecology Leather.Ecology Leather of the present utility model is made to have outward appearance and the sense of touch of corium, in the quality of performance with improving product in appearance.If can't meet the quality requirement of the thickness of corium powder cloth layer and corium powder, then the ecological skin prepared does not have outward appearance and the sense of touch of corium, and namely its third dimension is poor, gauffer is comparatively large, without pendency sense; If exceeded, then high the and bad mechanical property of production cost.
The upper surface of base cloth layer is coated with wet method bass coating formation wet method bass, and bass is benchmark in a wet process, is combined by polyurethane resin in its wet method bass coating with dry coating, at its base cloth layer by polyurethane resin bonding corium powder cloth layer.Corium powder cloth layer contains highdensity corium powder, has the institutional framework of corium, thus gives the variation of ecological epidermis sight, namely gives the texture of the perfect dermal incision of ecological skin, pendency, excellent mechanical performance.Line is rubbed to corium powder cloth layer, then after carrying out the process of mill skin to shaping Ecology Leather, makes this Ecology Leather have sense of touch and the sophistication of corium.So the utility model mainly improves the perfect adaptation being traditional synthetic leather and corium powder fabricbase.
Compared with the prior art, Advantageous Effects of the present utility model is:
1, the utility model has selected the corium powder cloth layer formed containing highdensity corium bisque and fibrous face, this corium powder cloth layer thickness is 0.8-1.0mm, there is institutional framework and the outward appearance of corium, and by rubbing line preliminary treatment to corium powder fabricbase, the pliability of adjustment corium powder fabricbase.
2, to be fitted one deck corium powder cloth layer by polyurethane resin at base cloth layer lower surface, make Ecology Leather integral thickness reach about 1.6mm, wherein the mass content of corium powder reaches more than 40%.Not only make the three-dimensional enhancing of the apparent decorative pattern of Ecology Leather, and all suitable with corium on suspension sense, the otch and dangle sense and thick and heavy sense of gauffer.
3, the physical and mechanical properties of Ecology Leather that four-layer structure of the present utility model is composited obviously is better than corium, and price is starkly lower than corium, and it is practical, can be applicable to high-grade sofa, seat etc., can meet the inexpensive demand of consumer greatly.
Detailed description of the invention
As shown in Figure 1, a kind of Ecology Leather of high corium content, described Ecology Leather comprises base cloth layer 1, and the upper surface of described base cloth layer 1 is coated with wet method bass coating 2 and forms wet method bass, and described wet method bass coating 2 is fitted with dry coating 3 by polyurethane resin; The lower surface of described base cloth layer 1 is bonded with corium powder cloth layer 4, described corium powder cloth layer 4 is bonded by the corium bisque of corium powder pressing and fibrous face to form, and the fibrous face of described corium powder cloth layer is bonded into one by the lower surface of polyurethane resin and base cloth layer.
In order to the outward appearance and the sense of touch that make Ecology Leather have corium, the thickness of described corium powder cloth layer is 0.8-1.0mm; The mass percent of corium powder is contained for being not less than 40% in described Ecology Leather.
In the utility model, wet method bass coating, dry coating etc. are all nouns named in method general in Synthetic Leather, wherein wet method bass is the intermediate products without any lines formed after base cloth top layer has been coated with one deck PU by wet processing, and directly polyamide or polyurethane is coated onto on base cloth in dry coating.And be wet method bass coating (polyurethane) is coated to by wet processing the wet method bass that base cloth layer is formed in the utility model, be more directly coated with one deck dry coating (polyamide or polyurethane) in wet method bass coating.
The present embodiment is only for the elaboration of this new technique content; but flesh and blood of the present invention is not limited in described in above-described embodiment; those of ordinary skill in the art can and any change based on connotation of the present invention and distortion should be known, protection domain of the present utility model should be belonged to.
