Outdoor yacht leather and preparation method thereof

Abstract

The invention relates to outdoor yacht leather and a preparation method thereof. The outdoor yacht leather comprises a base fabric layer, a wet-process PU bottom layer, dry-process PU surface layers and a surface treated layer which are sequentially arranged; the dry-process PU surface layers comprise a first dry-process PU surface layer, a second dry-process PU surface layer and a third dry-process PU surface layer which are sequentially formed between the wet-process PU bottom layer and the surface treated layer; the first dry-process PU surface layer is positioned between the second dry-process PU surface layer and the surface treated layer; the third dry-process PU surface layer is positioned between the wet-process PU bottom layer and the second dry-process PU surface layer; the wet-process PU bottom layer is a flame-retardant PU layer; and the first dry-process PU surface layer is an anti-mildew PU layer. The yacht leather disclosed by the invention not only meets requirements ofoutdoor leather for performance of corrosion resistance, ultraviolet resistance, hydrolysis resistance and the like, but also meets requirements of yacht leather for performance of seawater resistance, mildew prevention and bacteria resistance, meanwhile, further meets the environment protection requirement, and also has better ageing resistance than yacht leather made of a PVC material.

Description

technical field [0001] The invention belongs to the technical field of synthetic leather, and in particular relates to a leather for outdoor yachts and a preparation method thereof. Background technique [0002] Because outdoor leather is used outdoors, people have higher requirements for outdoor leather than ordinary leather. Outdoor leather requires corrosion resistance, UV resistance, hydrolysis resistance, and aging resistance. [0003] Yacht is a high-end consumer product for water entertainment that integrates navigation, sports, entertainment, leisure and other functions. A large amount of leather is used to decorate the yacht, but due to the special use environment of the yacht, the leather used on the yacht also needs to be resistant to seawater, mildew and antibacterial and other functions. [0004] Existing yacht leather commonly used is PVC products or silica gel products, such as Chinese patent CN108823992A has developed a kind of yacht leather, the yacht leath...

AI Technical Summary

Problems solved by technology

Although the yacht leather can be used on yachts, the yacht leather is still a PVC product, and PVC leather is usually unqualified for environmental protection. Therefore, countries such as Europe and the United States are gradually reducing its consumption, and PVC products also have disadvantages such as low aging resistance.

However, the price of silicone products is too high, and they are usually used in high-end yachts, so they are not suitable for large-scale promotion and use.
