Problems solved by technology

The demand for zirconia as a functional material and structural material is also increasing, and its production process cost is low, but the disadvantage is that it produces a large amount of waste (about 5m3 of dilute lye and acidic silicon slag are discharged per 1 ton of zirconia products) 1t)

Abstract

The invention discloses an outer ultraviolet-resistant polyethylene wallboard prepared from waste brick dregs and a production method of the wallboard. The wallboard is prepared from raw materials in parts by weight as follows: 70-75 parts of the waste brick dregs and the like. The outer wallboard takes ceramic waste as a main raw material, the clay resource is saved, the production cost is reduced, the problem about treatment of the ceramic waste is also solved, and environmental pollution caused by the ceramic waste is avoided; laminated dihydroxy composite metal hydroxide adopts a multi-level overlapped laminated structure comprising main laminated bodies, namely, double metal hydroxide laminates, and interlamination objects, namely, anions, and the laminated dihydroxy composite metal hydroxide has the excellent physical shielding effect on ultraviolet rays and can effectively improve the ultraviolet aging resistance.

Description

Technical field [0001] The invention relates to the technical field of building materials, and more specifically to a waste brick slag UV-resistant polyethylene exterior wall board and a production method thereof. Background technique [0002] At present, most bricks are made by clay sintering. However, as the amount of clay mining increases, clay resources are increasingly scarce, which not only increases mining costs, but also has a serious impact on the ecological environment. Therefore, it is urgent to optimize and improve the current situation. Some brick-making methods to change the status quo. [0003] Decomposing zircon sand with sodium hydroxide is the main production process for producing zirconium oxychloride and zirconium dioxide in my country. my country's annual production capacity of zirconium oxychloride in 2007 has reached 150,000 tons, ranking first in the world. The demand for zirconium dioxide as a functional material and structural material is also increasing...
