Problems solved by technology

Although the yacht leather can be used on yachts, the yacht leather is still a PVC product, and PVC leather usually has the problem of not meeting environmental protection requirements, and because the weight of the material itself is relatively large, the product weighs more than 500g per square meter, making the manufacturing process difficult. The finished product is very bulky, which also increases the weight of the yacht itself and increases the consumption during use, 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.

Abstract

The invention discloses double-sided inflatable yacht leather and a preparation method thereof, and belongs to the technical field of synthetic leathes.The yacht leather comprises a base cloth layer, resin layers and surface protection layers, the resin layers are compounded on the upper face and the lower face of the base cloth layer, the surfaces of the resin layers are coated with the surface protection layers, the resin layers are made of modified polyurethane resin, and the surface protection layers are made of polyurethane resin. The hydrolytic silyl group connected to the side chain or the tail end of the modified polyurethane resin molecule is subjected to a cross-linking reaction under the action of water and phosphoric acid to form a membrane; according to the yacht leather disclosed by the invention, the film has corrosion resistance, stability and certain elongation, and the yacht leather not only meets the corrosion resistance, ultraviolet resistance, seawater resistance, mildew resistance and antibacterial property of the yacht leather, but also meets the environment-friendly requirement.

Description

technical field [0001] The invention belongs to the technical field of synthetic leather, in particular to a double-sided inflatable yacht leather and a preparation method thereof. Background technique [0002] With the progress and development of the times, the demand for leather goods is not limited to genuine leather. Various imitation products can already replace some genuine leather products. Since the interview of artificial leather products, products with various textures and specifications have appeared on the market, and their functions have also been diversified. There are also different requirements for synthetic leather applied in different scenarios. [0003] A yacht is a consumer product for water entertainment that integrates functions such as navigation, sports, entertainment, and leisure. Yachts need a lot of leather for decoration, but due to the special environment of the yacht, the leather used on the yacht also needs to have functions such as seawater ...
