Problems solved by technology

Although oily wax leather has many advantages, it is deeply loved by people, but the existing oily waxy leather still has the following deficiencies: the first: certain water absorption and oil absorption are arranged, that is, water repellency is relatively poor, causing oily waxy leather to meet It is easy to change color in water and oil; second: its surface is prone to scratches and has poor scratch resistance, resulting in uneven leather surface
[0003] At present, there are very few reports about using two-layer leather to make high-grade waxy leather, so the applicant provides a flat waxy waxy leather made of two-layer leather to overcome the above shortcomings

Embodiment 1

[0034] The preparation method of the two-layer plane waxy oily wax skin specifically includes the following steps:

[0035] Step 1: Take the processed and dyed split skin, dry the split skin once, and vibrate to soften it to obtain vibrated soft skin. When vibrating, the vibrating value is set to 6, and the speed is 0.6cm / s;

[0036] Step 2: Grind the leather once, and use 180 # 、220 # Sand the bottom with 180 # 、280 # Grind the surface with sandpaper to get a buffed leather;

[0037] Step 3, Roller coating: Roll the paint onto the surface of the first-time grinding leather obtained in Step 2, and roll-coat it twice continuously to obtain a roll-coated leather. The ratio of rolling speed to conveyor belt speed during rolling coating is 20:10, and rolling twice The amount of wet coating applied is: 10g / SF for the first time and 6g / SF for the second time. The coating includes the following components in parts by mass: 600 parts of water, 400 parts of water-based polyacrylate...

Embodiment 2

[0047] The preparation method of the two-layer plane waxy oily wax skin specifically includes the following steps:

[0048] Step 1: Take the processed and dyed split skin, dry the split skin once, and vibrate until softened to obtain vibrated soft skin. When vibrating, the vibrating value is set to 7, and the speed is 0.7cm / s;

[0049] Step 2: Grind the leather once, and use 180 # 、220 # Sand the bottom with 180 # 、280 # Grind the surface with sandpaper to get a buffed leather;

[0050] Step 3, Roller coating: Roll the paint onto the surface of the first-time grinding leather obtained in Step 2, and roll-coat it twice continuously to obtain a roll-coated leather. The ratio of rolling speed to conveyor belt speed during rolling coating is 20:10, and rolling twice The amount of wet coating applied is: 8g / SF for the first time and 4g / SF for the second time. The coating includes the following components in parts by mass: 550 parts of water, 350 parts of water-based polyacrylat...

Embodiment 3

[0060] The preparation method of the two-layer plane waxy oily wax skin specifically includes the following steps:

[0061] Step 1: Take the processed and dyed split skin, dry the split skin once, and vibrate to soften it to obtain vibrated soft skin. When vibrating, the vibrating value is set to 6, and the speed is 0.5cm / s;

[0062] Step 2: Grind the leather once, and use 180 # 、220 # Sand the bottom with 180 # 、280 # Grind the surface with sandpaper to get a buffed leather;

[0063] Step 3, Roller coating: Roll the paint onto the surface of the first-time grinding leather obtained in Step 2, and roll-coat it twice continuously to obtain a roll-coated leather. The ratio of rolling speed to conveyor belt speed during rolling coating is 20:10, and rolling twice The amount of wet coating applied is: 12g / SF for the first time and 8g / SF for the second time. The coating includes the following components in parts by mass: 650 parts of water, 450 parts of water-based polyacrylate...

Abstract

The invention relates to a kind of planar waxy split leather and a manufacturing method thereof and belongs to the technical field of leathers. The manufacturing method of the planar waxy split leather comprises the following steps of selecting a split leather subjected to processing and dyeing treatment, conducting primary drying, vibration softening, primary leather buffing, roll coating, primary knurling, secondary leather buffing, water wax spraying, secondary drying, water wax rolling, tertiary drying, dye spraying and secondary knurling, and then obtaining the planar waxy split leather. The planar waxy split leather has good color fastness good water repellency and wet-dry friction resistance and is soft in hand feel and free of oily feel.

Description

technical field [0001] The invention belongs to the technical field of leather, and in particular relates to a two-layer plane waxy oily wax leather and a preparation method thereof. Background technique [0002] Oil wax leather is a kind of high-end leather material, which has an antique effect, is soft and elastic, has high tension, and generally has a thickness of 1.5-2.0mm. At present, the production process of oil wax leather is generally as follows: polishing the top layer of cowhide → oiling → waxing, so that the surface of the cowhide forms a special luster effect. Although oily wax leather has many advantages, it is deeply loved by people, but the existing oily waxy leather still has the following deficiencies: the first: certain water absorption and oil absorption are arranged, that is, water repellency is relatively poor, causing oily waxy leather to meet It is easy to change color when it is water and oil; second: its surface is prone to scratches and has poor s...
