A kind of outdoor yacht leather and preparation method thereof

Abstract

The invention relates to a leather for outdoor yachts and a preparation method thereof. The leather for outdoor yachts comprises a base cloth layer, a wet-process PU bottom layer, a dry-process PU surface layer and a surface treatment layer arranged in sequence. The dry-process PU surface layer comprises sequentially formed The first dry-process PU surface layer, the second dry-process PU surface layer and the third dry-process PU surface layer between the wet-process PU bottom layer and the surface treatment layer, the first dry-process PU surface layer is located on the second dry-process PU surface layer And between the surface treatment layer, the third dry PU surface layer is located between the wet PU bottom layer and the second dry PU surface layer, the wet PU bottom layer is a flame retardant PU layer, and the first dry PU surface layer is an anti-mildew PU layer. The yacht leather of the present invention not only satisfies the properties of outdoor leather such as corrosion resistance, ultraviolet resistance, and hydrolysis resistance, but also satisfies the seawater resistance, mildew-proof and antibacterial properties of yacht leather, and at the same time meets environmental protection requirements. Better aging resistance of leather.

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.
