Abstract

The utility model discloses a high-strength composite leather, comprising a leather base layer, a bonding layer and a fabric layer, wherein the bonding layer is located above the leather base layer, the fabric layer is located on the bonding layer, the leather base layer and the fabric layer are mutually fixed via the bonding layer, and the thickness ratio of the leather base layer to the fabric layer is 1: 1. The high-strength composite leather disclosed by the utility model has the following advantages that the leather with composite layers is formed by coating the bonding layer on a natural imitative leather material or an artificial leather which is manufactured by wastes and bonding the fabric layer, thus greatly enhancing the tensile strengths and shear strengths of the natural imitative leather material and the artificial leather, and improving the tear-resistant performance. The composite leather is environment-friendly leather without hexavalent chromium and formaldehyde, has the advantages of being non-toxic, capable of being recycled, easy to decompose and the like, and does not generate toxic gas or pollute water sources.

Description

The compound leather of a kind of high strength

Technical field

The utility model relates to a kind of leather, relates in particular to the compound leather of a kind of high strength.

Background technology

At present, when making leather,, just inevitably produce some and retain waste material, these are retained waste material utilize again,, produce multifunctional natural simulated leather material through multiple physics and chemical treatment for thickness and width to leather are regulated.

But above-mentioned natural simulated leather material and dermatine, its hot strength and shear strength are all more weak, therefore in use, are easy to torn, and therefore just press for a kind of composite leather of research and development, can overcome the shortcoming of above-mentioned leather.

The utility model content

The technical problem that the utility model will solve provides and a kind ofly can remedy the natural simulated leather material that utilizes the waste material manufacturing and the defective that dermatine is torn easily, hot strength is high, shear strength the is high compound leather of high strength.

In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: provide a kind of high strength compound leather; Comprise leather substrate, tack coat and precoat, said tack coat is positioned at above the leather substrate, and said precoat is positioned at above the tack coat; Said leather substrate and precoat interfix through tack coat, and said leather substrate is 1: 1 with the thickness ratio of precoat.

In order to prevent the precoat easy abrasion, the utility model is further optimized, and also includes the lining protective layer, and said lining protective layer is positioned at above the precoat.

Wherein, said lining protective layer is PU coating or PVC coating.

Wherein, the material of said leather substrate is natural leather or dermatine.

Wherein, the material of said precoat is bafta or chemical fibre or nonwoven.

For solving the problems of the technologies described above; Another technical scheme that the utility model adopts is: provide a kind of high strength compound leather; Comprise leather substrate, tack coat and precoat, said tack coat is positioned at above the leather substrate, and said precoat is positioned at above the tack coat; Said leather substrate and precoat interfix through tack coat, and said leather substrate is 2: 1 with the thickness ratio of precoat.

Wherein, said material protective layer is PU coating or PVC coating.

The beneficial effect of the utility model is; The utility model is through coating tack coat at natural simulated leather material or dermatine with the waste material manufacturing; And the bed of material above fitting; Form the leather of composite bed, strengthened the hot strength and the shear strength of natural simulated leather material and dermatine greatly, improve its tear resistance.Composite leather non-hexavalent chromium, formaldehydeless has nontoxic, recyclable utilization again, is prone to advantages such as decomposition, does not produce poison gas or polluted source.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.

Fig. 1 is the compound leather structural representation of the utility model high strength A;

Fig. 2 is the compound leather structural representation of the utility model high strength B.

Wherein, 1: leather substrate; 2: tack coat; 3: precoat; 4: the lining protective layer.

The specific embodiment

By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.

Embodiment 1

Please consult Fig. 1 in the lump; As shown in the figure; The embodiment of the compound leather of the utility model high strength comprises following components, by the leather substrate 1 that natural simulated leather material or dermatine constitute, is positioned at the tack coat 2 above the said leather substrate 1; This tack coat 2 can be by one or more combinations of polyurethane binder, acrylate adhesives, hot-melt adhesive; Be positioned at the precoat 3 above the above-mentioned tack coat 2, said precoat 3 is bonded as an integral body through the leather substrate 1 that acts on of tack coat 2, and the material of precoat 3 can adopt bafta or chemical fibre or nonwoven; Said leather substrate 1 is 1: 1 with the thickness ratio of precoat 3, and promptly leather substrate 1 has identical thickness with precoat 3.

Said structure; The utility model is coated tack coat 2 at natural simulated leather material or dermatine with the waste material manufacturing, and the bed of material 3 above fitting, and forms the leather of composite bed; Strengthen the hot strength and the shear strength of natural simulated leather material and dermatine greatly, improved its tear resistance.

In the present embodiment, on precoat 3, further apply one deck lining protective layer 4, this lining protective layer 4 is PU coating or PVC coating, and the compound leather of the utility model high strength is using or adding man-hour, and lining protective layer 4 can prevent precoat 3 wearing and tearing.

Embodiment 2

Please consult Fig. 2 in the lump; As shown in the figure, the embodiment of the compound leather of the utility model high strength comprises following components, the leather substrate 1 that is made up of natural simulated leather material or dermatine; Be positioned at the tack coat 2 above the said leather substrate 1; This tack coat 2 can be positioned at the precoat 3 above the above-mentioned tack coat 2 by one or more combinations of polyurethane binder, acrylate adhesives, hot-melt adhesive, and said precoat 3 is bonded as an integral body through the leather substrate 1 that acts on of tack coat 2; The material of precoat 3 can adopt bafta or chemical fibre or nonwoven, and said leather substrate 1 is 2: 1 with the thickness ratio of precoat 3.

The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
