Summary of the invention
The objective of the invention is provides a kind of intensity height according to prior art, and the good magnesia oxychloride cement aggregate of wear resisting property.
Technical scheme of the present invention is as follows: a kind of magnesia oxychloride cement aggregate, and it is formed by containing activated magnesia, magnesium chloride hexahydrate and glass, and the described mass ratio that contains magnesium oxide, magnesium chloride hexahydrate and glass in the active oxidation magnesium raw material is 1: 0.9-1.1: 0.1-1.Preferred, the described mass ratio that contains magnesium oxide, magnesium chloride hexahydrate and glass in the activated magnesia is 1: 1: 0.176.
Described glass is made up of raw glass and thin glass, and described raw glass is that glass cullet are crossed 40 mesh sieves, screen underflow mass percent≤40%; Described thin glass is that glass cullet are crossed 160 mesh sieves, screen overflow mass percent≤50%.
The granularity of described raw glass is greater than 40 orders, and the granularity of described thin glass is less than 160 orders.
The mass ratio of described thin glass and raw glass is 1: 0.01-100.Preferred, the mass ratio of described thin glass and raw glass is 1: 0.1-10.Most preferred, the mass ratio of described thin glass and raw glass is 1: 0.5.The intensity of the magnesia oxychloride cement in preferable range and wear resistance are best.
Another object of the present invention provides above-mentioned magnesia oxychloride cement aggregate processing method.
To contain activated magnesia, magnesium chloride hexahydrate and glass mixing and obtain described magnesia oxychloride cement aggregate, the wherein said mass ratio that contains magnesium oxide, magnesium chloride hexahydrate and glass in the active oxidation magnesium raw material is 1: 0.9-1.1: 0.1-1; Described glass is made up of raw glass and thin glass, and described raw glass is that glass cullet are crossed 40 mesh sieves, screen underflow mass percent≤40%; Described thin glass is that glass cullet are crossed 160 mesh sieves, screen overflow mass percent≤50%; The mass ratio of described thin glass and raw glass is 1: 0.01-100.
Glass is a kind of widely used building and finishing material, and the waste after glass uses is not fully utilized, and recovery utilization rate is not high.After the glass fragmentation, the part particle be a kind of material of well gaining in strength, and glass particle itself has very high wear resisting property in the form of sheets or bar-shaped.Segment glass is distributed in magnesia oxychloride cement inside, and brittle rupture can take place, to improve the intensity of magnesia oxychloride cement.And segment glass is distributed in the magnesia oxychloride cement surface, can strengthen the wear resistance of magnesia oxychloride cement.Utilize glass as the magnesia oxychloride cement stopping composition, not only made full use of the discarded glass resource, and can well improve the wear resistance and the intensity of magnesia oxychloride cement.
