The invention relates to the technical field of buildings, and particularly provides a stone protective agent as well as a preparation method and application thereof. According to the first aspect, the invention provides a stone protective agent which at least comprises the following preparation raw materials in parts by weight: 15-20 parts of alkyl alkoxy silane, 2-14 parts of amino alkoxy silane, 20-30 parts of ethyl silicate and 20-50 parts of a hydrocarbon solvent. The stone protective agent prepared by the invention can form a layer of reticular structure with a complex shape like a treeroot outside the stone from outside to inside, so that the stone has excellent functions of water resistance, acid and alkali resistance, aging resistance and the like, moisture can be effectively blocked, and the problems of spots and whitening are prevented.
本发明涉及建筑技术领域，更具体地，本发明提供了一种石材保护剂及其制备方法和应用。本发明第一方面提供一种石材保护剂，按重量份计，制备原料至少包括：15～20份烷基烷氧基硅烷、2～14份氨基烷氧基硅烷、20～30份硅酸乙酯、20～50份碳氢溶剂。本发明制备得到的石材保护剂能够从外向内在石材外部形成一层像树根形状复杂的网状结构，从而使得石材具有较为优异的防水、抗酸碱、耐老化等功能，可有效地阻断水分，防止长斑、白化现象的发生。
