Abstract: A nano protection coating for jewelry and method are disclosed which is formed from the listed materials by weight: aminopropyltriethoxysilane 0.5~3, Al 2 O 3 1~5, SiO 2 15~25, isopropyl alcohol 20~30, H 2 O 35~42. The producing method for nano protection coating of jewelry comprises the following steps: firstly, 1-~15 (weight units) of isopropyl alcohol is put into the SiO 2 nano powder and mixed evenly, then the Al 2 O 3 powder and aminopropyltriethoxysilane are put in, finally, the surplus isopropyl alcohol & the water are put in and mixed evenly until the coating liquor is produced. Secondly, the surface of the jewelry is cleaned. Thirdly, the coating liquor is sprayed onto the surface of the jewelry. Fourthly, the surface of the jewelry is dried, and then a strong solid protection coating is produced on the surface of the jewelry. Provided is a coating for jewelry, which has the effect of high rigidity, nice protection, and not easy to be damaged, and also provided is a simple and low cost method for jewelry coating.

Abstract translation: 公开了一种用于首饰和方法的纳米保护涂层，其由所列材料重量组成：氨基丙基三乙氧基硅烷0.5〜3，Al 2 O 3 1〜5，SiO 2 15〜25，异丙醇20〜30，H 2 O 35〜42。 首饰纳米保护涂层的制备方法如下：首先，将1〜15（重量单位）异丙醇放入SiO2纳米粉末中均匀混合，然后放入Al2O3粉末和氨基丙基三乙氧基硅烷， 将剩余的异丙醇和水均匀混合均匀，直至制成涂布液。 其次，清洁珠宝的表面。 第三，将涂布液喷到珠宝表面上。 第四，首饰的表面被干燥，然后在珠宝表面上产生强固体保护涂层。 提供一种用于首饰的涂层，其具有高刚性，良好的保护性和不易损坏的效果，并且还提供了用于珠宝涂层的简单且低成本的方法。
