Description

一种户外游艇用革及其制备方法Leather for outdoor yacht and preparation method thereof 技术领域Technical field

本发明属于合成革技术领域，具体涉及一种户外游艇用革及其制备方法。The invention belongs to the technical field of synthetic leather, and specifically relates to an outdoor yacht leather and a preparation method thereof.

背景技术Background technique

户外革由于是在户外使用，人们对户外革的要求相对普通用革更高，户外革要求耐腐蚀、耐紫外、耐水解、耐老化等。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.

游艇，是一种集航海、运动、娱乐、休闲等功能于一体的水上娱乐用高级消费品。游艇中通过大量的皮革来装饰，但是由于游艇的特殊使用环境，所以，用于游艇上的皮革还需要耐海水、防霉抗菌等功能。Yacht is a high-end consumer product for water entertainment that integrates navigation, sports, entertainment, and leisure functions. Yachts are decorated with a large amount of leather, but due to the special use environment of yachts, the leather used on yachts also needs functions such as seawater resistance, mildew resistance and antibacterial.

现有的游艇革常用的是PVC产品或硅胶产品，如中国专利CN108823992A开发了一种游艇革，该游艇革，包括底层和发泡层，所述底层原料包括PVC树脂粉100份，邻苯二甲酸二异癸60-90份，羟基锡酸锌6-10份，氢氧化铝25-40份，紫外吸收剂0.5-2份，热稳定剂2-4份，防胺剂1-3份，防霉剂0.2-0.8份；]所述发泡层原料包括PVC树脂粉100份，邻苯二甲酸二异癸60-90份，羟基锡酸锌2-4份，氢氧化铝50-75份，热稳定剂1-4份，防霉剂0.2-0.5份，发泡剂1-6份，整泡剂1-2份。该游艇革虽然可用于游艇上，然而该游艇革仍然是PVC产品，而PVC革通常存在环保不合格，所以，欧美等国家正在逐渐减少其用量，并且PVC产品还存在耐老化性较低等缺点。而硅胶产品价格又太高，通常用于高档游艇中，不适合大规模推广使用。Existing yacht leathers are commonly used PVC products or silicone products. For example, Chinese patent CN108823992A has developed a yacht leather. The yacht leather includes a bottom layer and a foamed layer. The bottom layer raw materials include 100 parts of PVC resin powder and phthalate. 60-90 parts of diisodecyl formate, 6-10 parts of zinc hydroxystannate, 25-40 parts of aluminum hydroxide, 0.5-2 parts of ultraviolet absorber, 2-4 parts of heat stabilizer, 1-3 parts of anti-amine agent, Antifungal agent 0.2-0.8 parts;] The foam layer raw materials include 100 parts of PVC resin powder, 60-90 parts of diisodecyl phthalate, 2-4 parts of zinc hydroxystannate, and 50-75 parts of aluminum hydroxide , 1-4 parts of heat stabilizer, 0.2-0.5 parts of antifungal agent, 1-6 parts of foaming agent, 1-2 parts of foam stabilizer. Although the yacht leather can be used on yachts, the yacht leather is still a PVC product, and PVC leather is usually environmentally unqualified. 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. . The price of silica gel products is too high, and is usually used in high-end yachts, not suitable for large-scale promotion.
