Embodiment 1

[0039] In parts by weight, the composition forming the bottom layer includes 100 parts of PVC resin powder, 50 parts of DOP plasticizer, 20 parts of ESPO plasticizer, 1.0 part of AC foaming powder, 100 parts of ground calcium carbonate, 2.0 parts of barium zinc heat stabilizer and 1.0 parts of lubricant.

[0040] In parts by weight, the composition forming the surface layer includes 100 parts of PVC resin powder, 60 parts of DOP plasticizer, 6 parts of ESPO plasticizer, 2.0 parts of barium zinc heat stabilizer and 20 parts of light carbonic acid calcium.

[0041] The bottom layer and the surface layer with a thickness of 0.22 mm are sequentially arranged on the base fabric by calendering technology, and the structural film layer with the bottom layer and the surface layer is sent to a foaming furnace for foaming to form a foam layer with a thickness of 0.25 mm. And the expansion ratio is 1.3 (thickness of the foam layer=thickness of the bottom layer×expansion ratio). Surface t...

Embodiment 2

[0044] The difference from Example 1 is that in the process of forming the surface layer, the running speed of the control roller is 18m / min.

Embodiment 3

[0046] The difference from Embodiment 1 is that: before setting the bottom layer, a glue layer is set on the surface of the base cloth, and the glue layer is arranged between the base cloth and the bottom layer. During the formation of the top layer, the rotational speed of the control roll was 12.5 m / min.

Abstract

The invention provides a leather and a production method thereof. The production method comprises the following steps: setting a water-based surface treating agent on the surface of a semifinished leather and drying, controlling the drying temperature of the water-based surface treating agent to be 100 DEG C to 130 DEG C and / or the drying speed to be at 10-18 m / min to form a surface treated layer. By using the production method, the surface treated layer is dried thoroughly, and the surface treated layer is more scratching-resistant and difficultly has a blushing phenomenon.

Description

technical field [0001] This application relates to the field of leather, in particular, to a kind of leather and its manufacturing method. Background technique [0002] The solvent in the water-based treatment agent is water. Compared with the oil-based treatment agent, the water-based treatment agent has no adverse effects on the health of workers during the coating process, and has no pollution to the atmospheric environment. The hidden danger of explosion is improved, and the safety is improved. [0003] It is precisely because of the above-mentioned advantages that water-based treatment agents are widely used in the surface treatment of leather. However, the surface of the leather treated with a water-based treatment agent is prone to scratch resistance and even whitening. Therefore, there is an urgent need for a method for improving the scratch resistance of the leather surface treated with an aqueous treatment agent. Contents of the invention [0004] The main pur...
