Description
Technical field
The present invention relates to a kind of cement and preparation method thereof, more particularly to a kind of anhydrous rapid-hardening magnesia oxychloride cement and its
Preparation method.
Background technology
Magnesia oxychloride cement its be first by Sweden's scholar's Sorel 1867 invention a kind of air hardening cementitious materials, it
By light-burned MgO, MgCl2And H2O three reconciles to be formed according to a certain ratio, and magnesia oxychloride cement has fast solidifying, preferably
Wearability, alkalescent and low-corrosiveness, prominent caking property, good anti-flammability, the advantages that preferable thermal insulation, have fine
Application prospect, but it is not that quickly, and can not lack the participation of this component of water that it, which condenses hardening, and this causes chlorine oxygen magnesium
Cement is initially located in moist or solution state from hardening is condensed, and causes it not to be suitable for some and need to dry to coagulate under anhydrous condition
The material of solidification is tied, so as to limit its application.
The content of the invention
It is an object of the invention to provide a kind of anhydrous rapid-hardening magnesia oxychloride cement and preparation method thereof, of the invention is made
Standby magnesia oxychloride cement need not add water and can be hardened with quick condense, and add the application side of magnesia oxychloride cement concrete
To, in the case where not adding water component rapid condensation harden, disclosure satisfy that it is many need dried over anhydrous environment condense constrictive type
The demand of material.
The purpose of the present invention is achieved through the following technical solutions：
A kind of anhydrous rapid-hardening magnesia oxychloride cement, by weight percentage, its component is the magnesia oxychloride cement:Magnesia (activity
85 powder for 65%) 12.7% ~ 16.5% (active quantities), Magnesium dichloride hexahydrate 22.1% ~ 35.9%, perlite 2.5% ~ 3.9%, sand
Stone (calcium carbonate) 37.9% ~ 58.0%, cosolvent 2.2% ~ 8.7%.
A kind of described anhydrous rapid-hardening magnesia oxychloride cement, the filler are sandstone (calcium carbonate), and perlite is used with.
A kind of described anhydrous rapid-hardening magnesia oxychloride cement, the magnesia are 85 powder that activity is 65%.
A kind of described anhydrous rapid-hardening magnesia oxychloride cement, the cosolvent are one in calcium hydroxide or sodium hydroxide
Kind.
A kind of preparation method of anhydrous rapid-hardening magnesia oxychloride cement, methods described include following preparation process：
（1）Weighed according to magnesia oxychloride cement each component weight percent content；
（2）The load weighted magnesia of content, magnesium chloride, perlite, sandstone and cosolvent by weight percentage is added together simultaneously
It is well mixed；
（3）Well mixed compound is added into ball milling in ball mill；
（4）The good magnesia oxychloride cement ball milling material of ball milling is added in mould and is compacted；
（5）Natural curing can be extremely stripped.
Advantages of the present invention is with effect：
The magnesia oxychloride cement of the present invention has water-tolerant, and moderate strength, in the case where not adding water component, rapid condensation is hard
Change, disclosure satisfy that many demands for needing dried over anhydrous environment to condense hardening profiles, e.g., fireworks big gun is stifled etc..With latent well
Scape before application.
