Nano-grade modified sintered brick and production method thereof

Abstract

The invention discloses a nano-grade modified sintered brick and a production method thereof. The brick is prepared from the raw materials of, by weight, 2-4 parts of nano-grade alumina, 10-15 parts of sculpture clay, 8-12 parts of sea mud, 5-10 parts of polyvinyl acetate, 4-6 parts of tung oil, 3-6 parts of waste syrup, 1-2 parts of sodium lauroyl sarcosinate, 3-5 parts of fir balsam, 4-8 parts of asbestos fiber, 6-8 parts of an additive, a proper amount of water, and the like. According to the invention, waste brick slag is adopted as a main raw material, such that clay resource is saved, production cost is reduced, a waste brick slag treatment problem is solved, and environment pollution caused by the waste brick slag is avoided. The sintered brick provided by the invention has the advantages of high strength, high bearing capacity, low density, low heat conductivity coefficient, wide application range, and good market prospect. The sintered brick meets the requirements of users. The added polyurethane elastomer has excellent wear resistance and oil resistance, and is a polar polymer which can be organically combined with polypropylene, such that polypropylene mechanical performances can be improved. The added fluororubber has the characteristics of high-temperature resistance, oil resistance and the like. With the other fillers other physical performances and processing performances can be enhanced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a nano-modified sintered brick and a production method thereof. Background technique [0002] At present, most bricks are prepared by sintering clay. However, with the increase of clay mining, clay resources are increasingly scarce, which not only increases the mining cost, but also has a serious impact on the ecological environment. Therefore, it is urgent to optimize and improve the existing bricks. There are 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 reached 150,000 tons in 2007, ranking first in the world. The demand for zirconia as a functional material and structural material is also increasing, and its production process cost is low, bu...

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)
