technical field

The invention relates to the technical field of leather, and more specifically relates to a novel leather.

Background technique

Leather is widely used in daily life, but none of the existing leathers can send out corresponding indication signals according to the magnitude of the force, which may cause major accidents due to sudden rupture of the leather due to excessive force in some occasions.

Contents of the invention

In order to overcome the deficiencies of the prior art, the invention provides a new type of leather, which can send corresponding signals according to the magnitude of the force to improve safety.

The technical solution adopted by the present invention to solve its technical problems is:

A new type of leather, comprising a leather body layer, an indication layer that sends out corresponding indication signals according to the magnitude of the force, and a reinforcement layer for strengthening the structure, the indication layer is laid on the outer surface of the reinforcement layer, and the leather body layer is laid on the outer surface of the indicator layer.

Preferably, a thermal insulation layer is laid between the indication layer and the reinforcement layer.

Preferably, the thickness of the leather body layer is 1-5 mm.

Preferably, the indicator layer has a thickness of 0.5-1.5 mm.

Preferably, the thickness of the reinforcing layer is 0.5-1.5 mm.

Preferably, the thickness of the thermal insulation layer is 1-3 mm.

Preferably, the material of the indicating layer is piezochromic material or piezoluminescent material.

Preferably, the reinforcement layer is made of nylon.

The beneficial effects of the present invention are: by setting the indicating layer, when the leather is stressed, the indicating layer will send out corresponding indicating signals to feed back the force information, which is convenient for personnel to know the force situation of the leather at any time, and avoids sudden fracture caused by excessive force, Improved security. The invention has good application effect and is easy to popularize and use.

Description of drawings

Fig. 1 is the structural representation of the novel leather of the present invention.

Among them: 1-leather body layer, 2-indication layer, 3-reinforcing layer, 4-insulation layer.

Detailed ways

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to accompanying drawing 1, a kind of novel leather of present embodiment, comprises leather main body layer 1, the indicator layer 2 that sends corresponding indicator signal according to the magnitude of force and the reinforcement layer 3 that is used for strengthening structure, and described indicator layer 2 is laid on On the outer surface of the reinforcement layer 3 , the leather body layer 1 is laid on the outer surface of the indication layer 2 .

Based on the above-mentioned technical features of the new type of leather, by setting the indicator layer 2, when the leather is stressed, the indicator layer will send a corresponding indicator signal to feed back the force information, which is convenient for personnel to know the force of the leather at any time, and avoids sudden stress caused by excessive force. break, improving safety. The invention has good application effect and is easy to popularize and use.

In this embodiment, a thermal insulation layer 4 is laid between the indicator layer 2 and the reinforcement layer 3, which can improve the thermal insulation performance of the leather. The thickness of the thermal insulation layer 4 is 1-3 mm.

In this embodiment, the thickness of the leather body layer 1 is 1-5 mm; the thickness of the indicator layer 2 is 0.5-1.5 mm; the thickness of the reinforcement layer 3 is 0.5-1.5 mm, and the reinforcement layer 3 The material is nylon.

In this embodiment, the material of the indicating layer 2 is piezochromic material or piezoluminescent material. These two materials are existing mature materials. The piezochromic material can change different colors according to the pressure, and can be recognized by the naked eye; the piezoluminescent material has obvious changes in the luminous color according to the pressure. For example, the patent document "A static pressure piezochromic material and its preparation method" (application number: CN201910217950.2, publication number: CN109929536A) discloses a piezochromic material, which has a discoloration range coverage under a pressure of 1atm-10GPa Visible light band (blue to red fluorescence 493nm-628nm), can be recognized by naked eyes. For example: blue fluorescence (493nm) at 1atm, green (545nm) at 4.6GPa, yellow (574nm) at 7GPa, and red (628nm) at 10GPa, and the fluorescence wavelength and static pressure have a good relationship Quantitative Relationship. In addition, the patent "a piezoluminescent material and its preparation method and application" (application number: CN201811562796.4, publication number: CN109749736A) discloses such a material, explains the piezoluminescent material, and introduces some existing Some materials, specifically: piezoluminescence is a phenomenon in which the luminescent color of fluorescent materials changes significantly under the action of external stimuli such as external forces (such as grinding, pressure, scraping, etc.), heating and solvent fumigation. Piezoluminescent materials have broad application prospects in the fields of light-emitting devices, sensors, and detection. Materials with piezoluminescent properties that have been reported so far include: anthracene derivatives, tetraphenylethylene derivatives, phenothiazine derivatives, anthraquinone derivatives, and boron-containing organic compounds. Therefore, this patent can accurately judge the force of the leather according to the change of the material of the indicating layer 2 made of pressed color-changing material or piezoluminescent material, so as to avoid accidents caused by sudden breakage of the leather.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and replacements can also be made, these improvements and replacements It should also be regarded as the protection scope of the present invention.
