Stone is a non-renewable resource. In order to implement sustainable development in the field of building materials, it is necessary to carry out feasible protection for the existing stone. At present, the performance of the protection materials is relatively single. How to give consideration to both waterproof and anti-corrosion and anti-pollution properties is the focus of this study. Using tetraethyl orthosilicate (TEOS) as silicon source and adding appropriate modifier (silicone oil), the modified silicon stone protective material was prepared by sol-gel method. The ratio ranges of water, ethanol, hydrochloric acid and TEOS were determined by experiments, which were 1:1, 1: 1 ∼ 1: 2, 1: 10 ∼ 1: 20 respectively, the reaction temperature was 60°C, and the reaction time was 3.5h. Under the experimental conditions, adding modifier hydroxyl silicone oil (0.2%) can improve the anti-corrosion and stain resistance of stone protection materials.
