Abstract

The invention provides a waterproof coating for Aga soil and a preparation method of the waterproof coating. The waterproof coating for the Aga soil is prepared from the following raw materials in percentage by mass: 50-80% of organic silicon, 2-5% of a silane coupling agent, 0.1-1% of silane coupling agent modified nanoparticles, 0.05-0.1% of a catalyst and the balance of a low-boiling-point organic solvent. According to the present invention, the waterproof coating is used for coating the surface of the Aga soil to form the waterproof coating layer with a micro-nano structure, and the waterproof coating layer has hydrophobicity and gas permeation, has good long-term effect, and has no significant influence on the original appearance and the original texture of the Aga soil.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, and in particular relates to a waterproof coating and a preparation method thereof, in particular to a waterproof coating for Arga soil and a preparation method thereof. Background technique [0002] Aga soil is a unique building material in Tibet, and its main components are siliceous limestone with calcium carbonate, silicon dioxide and a moderate amount of clay. Important Tibetan ancient buildings, such as Potala Palace, Sakya Monastery, Norbulingka, Guge Ancient City, etc., are generally constructed of Aga soil for roofs, walls and floors. Its main manufacturing process is to mix different grades of Aga raw soil with water to form a slurry, and repeatedly ram it with a special pestle. After the slurry is completely congealed, it is polished with pebbles, and then repeatedly polished with sheepskin dipped in ghee. The surface of the rammed Aga soil is smooth and beautiful, with st...
