Abstract
The invention relates to novel regenerated leather, which comprises a regenerated leather body, and an adhesive layer, an allochroic coating and a protective coating which are coated and superposed on the regenerated leather body sequentially, wherein raw materials of the adhesive layer and the allochroic coating consist of 100 weight portions of PU resin with hot pressing allochroic function, 1 to 4 weight portions of crosslinking agent and 5 to 20 weight portions of PU color cream; and raw materials for the protective coating consist of 100 weight portions of PU resin used by common synthetic leather, 10 to 70 weight portions of dimethyl formamide and 10 to 70 weight portions of toluene. The novel regenerated leather has the advantages that the adhesive layer, the allochroic coating and the protective coating coated and superposed on the regenerated leather body sequentially can endow the regenerated leather with vivid leather appearance effect by coating processing, and simultaneously the adhesive layer and the allochroic coating adopt the PU resin with the hot pressing allochroic function so that the regenerated leather has branding allochroic function. The novel regenerated leather can be applied in industries of pamphlet binding, leather products, and the like, and can be branded with clear and plumpy characters or patterns easily in use.
Description
Technical field
The present invention relates to a kind of leather and fur products, specifically is a kind of regenerated bark.
Background technology
Regenerated bark also claims skin chaff paper, is to utilize the offcut that produces in process hides waste material and the leatherware process, a kind of material that processes after the recovery.Regenerated bark can present various imitation leather expression effects through operations such as embossing, stamp and PU are compound, is widely used in industries such as leatherware, furniture, book cover.
At present, through the regenerated bark compound with PU, the surface possesses the appearance of corium and the texture of corium, can substitute corium in some field, is widely used.
Adorn auspicious industry when producing this, front cover can be used corium or imitation leather in a large number.Font on the strip of paper used for sealing or pattern were printings or directly extruded in the past.The font of printing does not have concave-convex sense, directly extrudes the contrast that the font of coming does not have color again.Market a kind of PU synthetic leather with branding colour change function on sale though it has the outward appearance of imitation leather, does not have the texture of corium, and whole skin emulation effect is not good.
Summary of the invention
The purpose of this invention is to provide a kind of outward appearance and texture that had both possessed corium, also possess the novel regenerated bark of branding colour change function simultaneously.
Technical scheme of the present invention is such: a kind of novel regenerated bark; comprise the regenerated bark body; also comprise and apply superimposed adhesive linkage, discoloration coating and protective finish on the regenerated bark body successively; the primary raw material of above-mentioned adhesive linkage and discoloration coating is the PU resin with hot pressing colour change function, and the primary raw material of above-mentioned protective finish is common use for synthetic leather PU resin.
PU resin, 1-4 weight portion bridging agent and 5-20 weight portion PU that the raw material of above-mentioned adhesive linkage and above-mentioned discoloration coating all mainly has a hot pressing colour change function by 100 weight portions form with color.
The raw material of above-mentioned protective finish mainly is made up of the common use for synthetic leather PU resin of 100 weight portions, 10-70 weight portion dimethyl formamide and 10-70 parts by weight of toluene.
Above-mentioned PU resin with hot pressing colour change function is that to open up the model that luxuriant chemical industry Co., Ltd sells be the PU resin of FUD2605-1 in the Wuxi.
Above-mentioned bridging agent is that to open up the model that luxuriant chemical industry Co., Ltd sells be the bridging agent of H-501 in the Wuxi.
After adopting such scheme; a kind of novel regenerated bark of the present invention; its beneficial effect is: apply successively on the regenerated bark body and be superimposed with adhesive linkage, discoloration coating and protective finish; process by coating; can give regenerated bark leather appearance true to nature; simultaneously because adhesive linkage and discoloration coating have adopted the PU resin with hot pressing colour change function, thereby make regenerated bark have the function of branding variable color.Product of the present invention can be applied to these binding and layout, industries such as leatherware, and it is clear easily to brand out during use, plentiful font or pattern.
The specific embodiment
