Abstract

The invention relates to a transparent hydrophobic protective agent for cultural relic protection as well as a preparation method and a use method thereof, and the transparent hydrophobic protective agent for cultural relic protection is prepared from the following raw materials: 50-150 parts of methyltrimethoxysilane, 20-80 parts of dimethyldimethoxysilane, 10-40 parts of 3-glycidoxypropyltrimethoxysilane, 4-15 parts of tetrabutyl titanate, 25-75 parts of a solvent, 10-40 parts of deionized water and 1-4 parts of a catalyst. The solvent is one or a combination of more of methanol, ethanol, 1-propanol, 2-propanol, acetone and diacetone alcohol; and the catalyst is one or a combination of more of glacial acetic acid, hydrochloric acid, nitric acid and phosphoric acid. The invention also provides a preparation method and a use method of the transparent hydrophobic protective agent for cultural relic protection. The protective agent is low in viscosity, good in permeability and good in weather resistance, has good binding power, adhesive force and compatibility with a cultural relic substrate after being coated on the surface of the cultural relic, has reversibility, is non-toxic and environment-friendly, and does not change the appearance of the cultural heritage.

Description

Technical field [0001] The present invention relates to a coating for cultural relics, specifically a cultural relics protecting a transparent hydrophobic protectant. The invention also relates to the preparation method and method of use of the cultural relics protection of transparent hydrophobic protectants. Background technique [0002] The cultural relics are the relics or relics left in the process of transforming the objective world and subjective world. It is historical, national cultural heritage, and a social civilization and national spirit of physical chemical carrier. The cultural relics are non-renewable cultural resources, and they have received much attention from the general attention of countries around the world, and has received much attention with social development and civilization. The cultural relics as a special protective object, and its protection is imminent. [0003] The cultural relics protect the coating differs from ordinary anti-corrosion coatings....
