Problems solved by technology

In order to solve this problem, people have changed the elastic rubber pad between the glass substrate and the table to a conductive rubber material, but the effect is not ideal because the conductivity is still too large.
In addition, the dust generated in the leather processing process (such as leather grinding, etc.) is absorbed by the leather material, thus affecting the adhesion of the coating
During the use of leather materials, static electricity will be generated due to friction and other reasons, and it will also absorb pollutants such as dust, which will affect the aesthetics and hygienic performance of leather.

Embodiment 2

[0012] Example 2: first put the raw skin in the drum and soak it in water for 12 hours. After the raw skin is fully softened, adjust the liquid ratio to 2.0 and then add sodium sulfide so that the concentration of sodium sulfide is 5 grams per liter, and continue to soak in the drum. After turning for 1.8 hours, add 3.8% of the weight of the raw hide with a mass concentration of 30% sodium hydroxide, continue to turn for 1 hour, then wash with water, deash, and soften; secondly, adjust the liquid ratio to 1.0, and add the raw hide to the softened raw hide 14% salt by weight rotated for 10 minutes, then added 1.2% of the mass concentration of raw hide weight from the shaft hole as 98% sulfuric acid and 1.6% of the raw hide weight by 37% acetic acid and rotated for 1.5 hours, and tanned with iron tanning agent at room temperature 3 hours, stand still for 12 hours, planing, shaving, weighing, retanning with acrylic resin retanning agent for 5 hours, adjust the liquid ratio to 1.5,...

Embodiment 3

[0013] Example 3: first place the raw skin in the drum and soak it in water for 18 hours. After the raw skin is fully softened, adjust the liquid ratio to 1.3 and then add sodium sulfide so that the concentration of sodium sulfide is 8 grams per liter, and continue to soak in the drum. After turning for 1.6 hours, add 4.2% of the weight of raw hide with a mass concentration of 30% sodium hydroxide, continue to turn for 1 hour, then wash with water, deash, and soften; then adjust the liquid ratio to 1.2, and add raw hide to the softened raw hide 10% by weight of salt and rotated for 10 minutes, then add 1.4% of the mass concentration of raw hide weight as 98% sulfuric acid and 1.2% of raw hide weight from the shaft hole as 37% acetic acid and rotate for 1.0 hour, and tan with iron tanning agent at room temperature 3 hours, stand still for 12 hours, planing, shaving, weighing, retanning with acrylic resin retanning agent for 6 hours, adjust the liquid ratio to 1.1, and then add 1...

Embodiment 4

[0014] Example 4: First put the raw skin in the drum and soak it in water for 24 hours. After the raw skin is fully softened, adjust the liquid ratio to 1.7 and then add sodium sulfide so that the concentration of sodium sulfide is 9 grams per liter, and continue to soak in the drum. After turning for 2 hours, add 4.5% of the weight of raw hide with a mass concentration of 30% sodium hydroxide, continue to turn for 1 hour, then wash with water, deash, and soften; secondly, adjust the liquid ratio to 1.5, and add raw hide to the softened raw hide 15% by weight of salt and rotated for 10 minutes, then add 1.5% of the weight of the raw hide from the shaft hole with a mass concentration of 98% sulfuric acid and 2% of the weight of the raw hide with a mass concentration of 37% acetic acid, rotate for 0.8 hours, and tan with an iron tanning agent at room temperature 3 hours, stand still for 12 hours, planed, shaved, weighed, and then retanned with acrylic resin retanning agent for 4 ...

Abstract

An antistatic leather and a preparation method thereof, the leather material includes a leather body, and a layer of conductive film coating is coated on the outer surface of the leather body. The present invention coats the conductive film coating with good conductivity on the surface of the leather body, which improves the surface conductance of the leather material; and the leather contains a large amount of conductive mechanisms such as electrons and ion groups. When the electric field acts on the leather material, the charged ions will Across the potential barrier, conduction occurs; the above two mechanisms can act simultaneously to achieve the purpose of antistatic.

Description

technical field [0001] The invention relates to a leather, in particular to an antistatic leather and a preparation method thereof. Background technique [0002] Leather is a natural polymer material known and used earlier by humans. The main component is collagen fibers. Leather materials have the following advantages: easy to process and shape, and can be processed into various finished products with large width and uniform thickness; , Corrosion resistance, low density, high elasticity, heat resistance, cheap price and so on. It is because of these advantages that it is widely used in daily life and industrial and agricultural production to provide convenient conditions. [0003] The problem of electrostatic breakdown has plagued the microelectronics and LCD industries. The so-called electrostatic breakdown problem means that a large amount of static electricity generated during production cannot be released. When the voltage reaches a certain level, it will cause elect...
