Cement-based mortar photosensitive uvioresistant protective agent and preparation method thereof
The invention discloses a cement-based mortar photosensitive uvioresistant protective agent. The cement-based mortar photosensitive uvioresistant protective agent comprises the following components in parts in proportion: 10-15 parts of a 2, 4-dihydroxybenzophenone light absorbing dye solution, 5-10 parts of copper sulfate, 1-2 parts of sodium hydroxide, 5-10 parts of thiourea, 8-10 parts of a stannous chloride ethanol solution and 53-71 parts of a gelatine solution, wherein the total number of all the components is 100 parts. Besides, the invention discloses a preparation method of the protective agent. The protective agent and the preparation method thereof disclosed by the invention have the advantages that a light absorbing dye for absorbing ultraviolet rays and a reducing agent are adopted; besides, bivalent tin ions and gelatin form a glue film which is difficult to dissolve into water, so that erosion of the ultraviolet rays to a polymer in waterproof mortar is effectively blocked, the inner layer of the waterproof mortar is protected, the mortar protects macromolecular polymers and pigments from being directly radiated by the ultraviolet rays, the occurrence of phenomena that the surface of the mortar is pulverized, the crust of the mortar is peeled and the pigments fade can be eliminated, and the service life of the waterproof mortar is greatly prolonged.
