Abstract
The utility model belongs to the technical field of the synthetic leather and specifically relates to indicate a corrosion-resistant synthetic leather comprises base member layer and surface course, and the base member layer includes non-woven fabrics fibre, PU foaming layer, the surface course includes corrosion-resistant layer, wearing layer, top layer waterproof stamp, and corrosion-resistant layer is through high temperature anti-aging processing. Base member layer non-woven fabrics fiber carries out the acupuncture processing after adopting wet process to handle, form the short-staple, the PU foamer is a polyurethane, add fire retardant and hydrosolvent misce bene back and coat on the non-woven fabrics fiber, form intensive porous structure, then evenly paste the corrosion inhibitor of the material that the principal ingredients is polytetrafluoroethylene and cover on the loose porous structure on base member layer, form the inner protective layer, later with the wearing layer coating and the corrosion inhibitor outside, adopt at last the gluing agent to glue the waterproof stamp environmental protection micropore biomembrane in top layer on the leather surface, generate a corrosion-resistant synthetic leather.
Description
Technical Field
The utility model relates to a synthetic leather field especially indicates a corrosion-resistant synthetic leather.
Background
Natural leather, because its characteristics such as soft, light, cold-proof comfortable are liked by people, in recent years, along with people's demand to leather goods is bigger and bigger, natural leather is because the restriction of its output and production technology, the phenomenon that the confession is short of asking appears, for market demand, and environmental protection principle, synthetic leather begins to replace natural leather and satisfies market demand, but current synthetic leather technique still has more not enough, for example synthetic leather is easy to wear, not corrosion-resistant etc. if can solve this kind of technical problem, the synthetic leather will receive more favour.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a corrosion-resistant synthetic leather improves the corrosion resistance of synthetic leather.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the corrosion-resistant synthetic leather comprises a base body layer and a surface layer, wherein the base body layer comprises non-woven fabric fibers and a PU foaming layer, the surface layer comprises a corrosion-resistant layer, an abrasion-resistant layer and a surface layer waterproof printing layer, and the corrosion-resistant layer is subjected to high-temperature anti-aging processing treatment.
Furthermore, the PU foaming layer is made of flame-retardant polyurethane materials, and the PU foaming layer is uniformly coated on the non-woven fabric fibers.
Furthermore, the corrosion-resistant layer is made of polytetrafluoroethylene materials subjected to high-temperature anti-aging processing, and is uniformly adhered to the loose porous structure of the substrate layer.
Further, the wear-resistant layer is water-soluble resin, and the wear-resistant layer is adhered to the corrosion-resistant layer.
Further, the surface waterproof printing is an environment-friendly microporous biological membrane.
The utility model has the advantages that:
in the practical application scenario, the non-woven fabric fibers of the base layer are subjected to needle punching processing after being treated by a wet method to form short fibers, the PU foaming agent is a polyurethane material, a flame retardant is added, and the polyurethane material is uniformly mixed with a hydrosolvent and then coated on the non-woven fabric fibers to form a dense porous structure, then an anti-corrosion agent of a polytetrafluoroethylene material with the main component subjected to high-temperature anti-aging processing is uniformly adhered on the loose porous structure of the base layer to form an inner protective layer, then the wear-resistant layer is coated on the outer side of the anti-corrosion layer, and finally, the surface layer waterproof printing environment-friendly microporous biological membrane is adhered on the surface of the leather by adopting an adhesive, so that the anti-.

Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
As shown in fig. 1, the utility model provides a pair of corrosion-resistant synthetic leather, including base member layer 1, surface course 2, be present fixed knot structure above, base member layer 1 includes non-woven fabrics fibre 11, PU foaming layer 12, surface course 2 includes corrosion-resistant layer 21, wearing layer 22, top layer waterproof stamp 23, corrosion-resistant layer 21 is through ageing processing.
In this embodiment, PU foaming layer 12 evenly coats in the loose porous structure of non-woven fabrics fibrous layer 11, and corrosion-resistant layer 21 coats in proper order on PU foaming layer 12, then wearing layer 22 glues to cover on corrosion-resistant layer 21, glues the waterproof stamp in top layer with gluing agent at last, adopts this kind of structure, with corrosion-resistant layer as for the middle level, and corrosion-resistant layer 21 is through ageing processing, can more effectual whole synthetic leather of protection, increase of service life.
As shown in fig. 1, the PU foam layer 12 is made of flame retardant polyurethane, and the non-woven fabric fibers 11 are uniformly covered with the PU foam layer 12. In this embodiment, the PU foam layer 12 is made of flame retardant polyurethane material, and the flame retardant polyurethane material is added with a flame retardant during the production process, and directly covers the porous structure of the nonwoven fabric 11, so as to increase the air permeability and flame retardancy.
As shown in fig. 1, the corrosion-resistant layer 21 is made of teflon, and the corrosion-resistant layer 21 is uniformly adhered to the loose porous structure of the substrate layer 1. In this embodiment, the corrosion-resistant layer 21 mainly comprises a polytetrafluoroethylene material, and the polytetrafluoroethylene material has good corrosion resistance, can effectively protect the substrate layer, and has good acid corrosion resistance and alkali corrosion resistance.
As shown in fig. 1, the wear-resistant layer 22 is made of water-soluble resin, and the wear-resistant layer 22 is adhered to the corrosion-resistant layer 21. In the embodiment, the leather surface can be well protected.
As shown in fig. 1, the surface waterproof stamp 23 is an environmentally friendly microporous biofilm. In this embodiment, environmental protection micropore biomembrane environmental protection is light, and microporous structure can guarantee the gas permeability of synthetic leather in waterproof, can adopt the stamp to glue glutinous technique simultaneously, can increase the surperficial line variety of synthetic leather, increases the aesthetic feeling.
