Problems solved by technology

However, the football special leather also does not carry out surface treatment on the PU surface layer, so the wear resistance and scratch resistance cannot be guaranteed, and the base fabric needs to be treated with calcium nitrate treatment solution before coating, the preparation method is complex and the steps are cumbersome.

Embodiment 1

[0038] The football leather provided in this embodiment comprises a base cloth layer, a dry-process PU bottom layer, a dry-process PU middle layer, a water-based non-yellowing PU surface layer and a surface treatment layer arranged in sequence, and the dry-process PU bottom layer of the football leather , The raw material formula of the dry-process PU middle layer and the surface treatment layer is shown in Table 1-2.

[0039] In this example, the base fabric layer is 250g white warp-knitted fabric from Jiangsu Beltford New Material Co., Ltd.

[0040] In this example, the raw materials of the water-based non-yellowing PU surface layer are composed of the following components: 100 parts of Huafon’s JF-PDY-877HY water-based aliphatic PU resin, 8 parts of Maicai’s S19-LR08 water-based color paste, and 0.8 parts of Effie Luo's leveling agent and 0.4 part of Effie's thickener.

[0041] The football leather is prepared through the following steps:

[0042] (1) According to the for...

Abstract

The invention relates to football leather and a preparation method thereof. The football leather comprises a base cloth layer, a dry-method PU bottom layer, a dry-method PU middle layer, a water-based non-yellowing PU surface layer and a surface treatment layer which are arranged in sequence, wherein PU resin in the water-based non-yellowing PU surface layer is specific water-based aliphatic PU resin, so that the yellowing resistance problem is solved, the adhesive force of the water-based non-yellowing PU surface layer and the PU middle layer is good, the separation phenomenon of the existing water-based PU resin layer and the PU middle layer is greatly reduced, and yellowing is avoided; and meanwhile, the specific surface treatment layer, the PU bottom layer, the PU middle layer and the base cloth layer are matched for use, so that the football leather not only meets the wear resistance, ultraviolet resistance, hydrolysis resistance and aging resistance of the football leather, but also meets the oil stain resistance, environment friendliness and other properties; and particularly, raw materials of the surface treatment layer are brushed on the PU surface layer, and resin and a cross-linking agent are subjected to a cross-linking reaction to form a dense film after high temperature treatment, so that the water resistance and wear resistance of the football leather are further improved.

Description

technical field [0001] The invention belongs to the technical field of synthetic leather, and in particular relates to a football leather and a preparation method thereof. Background technique [0002] In recent years, the application field of synthetic leather has been continuously expanded, and the development of ball leather products has become more and more extensive, such as basketball leather, football leather, volleyball leather, etc. Different ball leather products require different physical properties, such as basketball leather. Elasticity, mechanical strength, chemical resistance, moisture absorption and perspiration, anti-slip properties, etc.; volleyball leather requires fine leather surface, plump and elastic, uniform thickness, small elongation and basically the same longitudinal and transverse directions, lighter than basketball leather It is softer, not loose or cracked, and has good wear resistance and water resistance; while football leather is slightly th...
