Abstract
The invention discloses a method for preventing the ultraviolet irradiation from changing the color of marble. The method comprises the following steps of: applying a coating on the front side of the marble, and controlling the coating thickness to be 0.01 to 0.1mm. According to the formula, the coating consists of the following components in part by weight: 40 to 60 parts of film-forming substance, 20 to 30 parts of zinc-cerium composite powder nano-slurry and 4 to 10 parts of aid. A method for preparing the coating comprises the following steps of: when the coating is prepared, adding the film-forming substance into a reactor; and adding the aid under stirring, adding the zinc-cerium composite powder nano-slurry, and uniformly stirring to obtain the coating. By compounding of two materials, namely CeO2 and ZnO in the zinc-cerium composite powder nano-slurry, the respective disadvantages of the two materials in use can be overcome; CeO2 can remarkably improve the ultraviolet shielding performance of materials; and ZnO has the ultraviolet shielding performance, and can also inhibit the catalytic oxidation performance of CeO2. Through the detection, a yellowing phenomenon is avoided after marble slabs are pasted for one year, and the ultraviolet shielding rate is over 90 percent.
Description
Technical field
The present invention relates to the treatment process of a kind of construction and decoration, particularly relate to a kind of method of preventing UV-irradiation to make the marble slab variable color with marble slab.
Background technology
Marble is meant the various carbonate rocks that have decoration functions and also can polish, polish, the silicates rock of compound carbonate.The marble quality is fine and smooth, decorative pattern is changeable, beautiful in colour, be easy to processing and polishing, but hardness is low, and wear resistance has high compression strength and good physical and chemical performance than granite difference.Marble is high retaining indoor hardware fitting, and the finishing of saloon bar and villa all can't do without the marble used.The Along with people's growth in the living standard, common other suite finishing also likes use marble, to improve the quality of fitting up.Even white marmorean metope and the ground furniture that is equipped with white become after the model of letter extremely.
But the yellowing phenomenon often appears in marble ground, metope, has greatly influenced whole fitting-out work quality.Especially exterior wall is used marble slabs, because the irradiation of UV-light, makes marble variable color after after a while, yellowing.Generally speaking, the exterior wall of common marble finishing the variable color situation will occur through behind the 2-3, and some high-grade marbles also have similar phenomenon through the longer time, and this brings serious prestige problem for finishing enterprise.Do not find the special treatment measures that make the marble slab variable color to UV-irradiation at present as yet.
