preparation example Construction

[0026] The present invention also protects a method for preparing the above-mentioned sweat-resistant leather, which includes the following steps:

[0027] Add acrylic resin and treatment agent to leather powder, stir and mix evenly, and place it at 50°C-70°C for a period of time to obtain the first intermediate product; add cotton powder or fiber powder, aluminum salt to the first intermediate product , cyclohexasiloxane, dimethylisosorbide, binder and solvent, stir evenly, and dry at 60°C-80°C for a period of time to obtain the second intermediate product; press the second intermediate product under a certain pressure, sweat-resistant layer;

[0028] bonding the sweat-resistant layer to one side of the leather layer through an adhesive;

[0029] The surface of the sweat-resistant layer is coated with silica gel, and the silica gel layer is obtained after drying.

Embodiment 1

[0035] In Example 1, the sweat-resistant layer is made by the following method: grind leather and cotton into powder, add acrylic resin and treatment agent to the leather powder, stir and mix, and place it at 60°C for a period of time to obtain the first Intermediate product: add cotton powder, aluminum chloride hydrate, cyclohexasiloxane, dimethyl isosorbide, binder and solvent to the first intermediate product, stir evenly, and dry at 70°C for 2 hours to obtain the second intermediate product product; the second intermediate product is pressed under a certain pressure into an elastic leather-like layer to obtain a sweat-resistant layer. The treatment agent is made by the following method: add starch, deionized water, and hydrogen peroxide into the reaction container, and keep it warm at 92°C for 1.5 hours to obtain a degraded starch solution; add glutaraldehyde and p-toluene sulfonate to the degraded starch solution acid, control the reaction temperature at 78°C, and react f...

Embodiment 2

[0036]In Example 2, the sweat-resistant layer is made by the following method: the leather and the fiber are powdered separately, acrylic resin and a treatment agent are added to the leather powder, stirred and mixed, and left for a period of time under an environment of 50° C. to obtain the first Intermediate product: add fiber powder, aluminum chloride hydrate, cyclohexasiloxane, dimethyl isosorbide, binder and solvent to the first intermediate product, stir evenly, and dry at 60°C for 1 hour to obtain the second intermediate product product; the second intermediate product is pressed under a certain pressure into an elastic leather-like layer to obtain a sweat-resistant layer. The treatment agent is made by the following method: add starch, deionized water, and hydrogen peroxide into the reaction vessel, and keep it warm at 90°C for 2 hours to obtain a degraded starch solution; add glutaraldehyde and p-toluenesulfonic acid to the degraded starch solution to control The reac...

Abstract

The invention discloses sweat-resistant leather and a preparation method thereof. The sweat-resistant leather comprises a leather base layer, a bonding layer, a sweat-resistant layer and a silica gelsurface layer which are connected in sequence, and the sweat-resistant layer is prepared from the following components: leather powder, a treating agent, acrylic resin, cotton powder or fiber powder,hydrated aluminum chloride, cyclohexasiloxane, dimethyl isosorbide, an adhesive and a solvent. The preparation method of the sweat-resistant leather comprises the following steps: adding the acrylic resin and the treating agent into the leather powder, performing uniform mixing under stirring, and allowing the mixed material to stand for a period of time to obtain a first intermediate product; adding the cotton powder or the fiber powder, the hydrated aluminum chloride, the cyclohexasiloxane, the dimethyl isosorbide, the adhesive and the solvent into the first intermediate product, performinguniform stirring, and performing drying for a period of time to obtain a second intermediate product; pressing the second intermediate product to obtain the sweat-resistant layer; bonding the sweat-resistant layer to one surface of the leather layer through an adhesive; and coating the surface of the sweat-resistant layer by silica gel, and performing drying to obtain the silica gel layer. The sweat-resistant leather provided by the invention can prevent stink caused by sweat.

Description

technical field [0001] The invention belongs to the technical field of leather, and in particular relates to a sweat-resistant leather and a preparation method thereof. Background technique [0002] Leather is a common item in people's daily life, whether it is shoes, belts, clothes, cars, etc. all need leather. And along with the raising of people's living standard, corium is more and more widely used in above-mentioned daily necessities. But whether it is real leather or artificial leather, there is the defect of not being resistant to sweat. When it is prepared into leather shoes and belts, it is easy to cover sweat and produce stink. Contents of the invention [0003] Based on this, it is necessary for the present invention to provide a kind of sweat-resistant leather that can prevent sweat from covering up and producing stink. [0004] The invention also provides a preparation method of the sweat-resistant leather. [0005] In order to realize the purpose of the pr...
