Composited nano sintered calcium silicate brick and production method of same

Abstract

The invention discloses a composited nano sintered calcium silicate brick and a production method of same. The composited nano sintered calcium silicate brick is prepared from following raw materials, by weight, precipitated barium sulphate, ultrafine barium sulfate, modified nano titanium dioxide, fly ash, hydrated lime, silicone lime, antimonous oxide, polyvinyl chloride resin, dioctyl sebate, dimethyl terephthalate, an anti-oxidant 616, tetrabromophthalic anhydride and polyvinyl chloride resin and the like. In the invention, by means of a synergistic effect between the added antimonous oxide and chlorine in the polyvinyl chloride resin, the polyvinyl chloride is enhanced in flame retarding performance. The dioctyl sebate, the dimethyl terephthalate, the anti-oxidant 616 and the tetrabromophthalic anhydride form a compounded plasticizer is matched with the polyvinyl chloride resin, so that positive effect of the plasticizer achieved maximum value. The brick is improved in low temperature resistance and meanwhile is reduced in usage quantity of the plasticizer, thereby enhancing flexibility.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composite nanometer sintered calcium silicate 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 ...

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)
