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 a mildew-proof and corrosion-resistant composite nano calcium silicate brick, which is prepared by mixing an ethylene-vinyl acetate copolymer with a compounded plasticizer composed of diisodecyl phthalate, [beta]-diketone and ammonium polyphosphate. The brick is improved in mechanical performance and meanwhile is enhanced in anti-aging performance and processability and can enhance flexibility of cables. The ammonium polyphosphate has the effect of a condensed phase and is mixed with magnesium hydroxide to achieve excellent flame-retarding effect. In addition, the sintered brick is high in strength, is strong in bearing capability, is low in density, is low in heat conductivity coefficient and can satisfy use requirement, is wide in application range and is good in market prospect. The sintered brick can reduce environment pollution of industrial solid waste discharge, is low in cost and less in pollution, is less in damage on human body, is good in abrasion resistance, is strong in anti-aging performance and also achieves economic and social benefit of turning waste into resources.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a mildew-resistant and anti-corrosion composite nano-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 increasin...
