Abstract

The present invention relates to a composite powder body air-hardening acid-resistante cement. It is made up by using powder body materials of 20-70% of powdered sodium silicate whose modulus (silicon-sodium ratio) M is equal to 2.3-3.0, 0-8% of additive, 10-30% of siliceous lime, 0-30% of fly ash, 0-30% of combination clay and 0-30% of porcelain powder through a certain combination process. Said product can be directly mixed with various acid-resistant aggregates, and can be made into the acid-resisting concrete, acid-resisting mortar and acid-resisting daub, etc.

Description

Composite granule air-setting acid-proof cement and preparation method thereof
Technical field:
The present invention relates to a kind of cement and compound method thereof, relate in particular to air-setting acid-proof cement of unsetting acid resisting materials such as a kind of acid resisting concrete, acid resisting mortar and acid resistant adhesive mortar and preparation method thereof.
Background technology:
The acid-proof cement that uses in unsetting acid resisting material such as acid resisting concrete, acid resisting mortar and acid resistant adhesive mortar is powders mixtures such as cast stone, quartz, flyash, in fact just the weighting agent of wedding agent.Also will add a certain amount of modified liquid water glass (water glass) for preparing in advance during use is mixed together with acid-resisting aggregate and could becomes goods.This method complex process, the transportation of material and storage inconvenience, the quality guaranteed period is short, causes environmental pollution easily.Therefore, very need a kind of powder type air-setting acid-proof cement that just can make goods that directly cooperates in the engineering with acid-resisting aggregate.
Summary of the invention:
The objective of the invention is to: traditional acid-proof cement must be used with liquid modifying water glass, and in fact it is a kind of acid-resistant powder, only plays filling effect.In order to change complicated construction technology, improve the various performances of goods, in acid-resistant powder, add powdery sodium silicate and admixture (or directly using modified powdery sodium silicate), active SiO 2, composite granule air-hardening cement such as bonding clay (white clay), flyash.After this product adds various acid resisting materials, just can make unsetting acid resisting material as long as add a certain amount of water.
The present invention is achieved in that and will touches the powdery sodium silicate 20～70% of number (silicon sodium ratio of water glass) M=2.3～3.0; Admixture (as tripoly phosphate sodium STPP) 0～8%; Silicon ash (active SiO 2) 10～30%; Bonding clay 0～30%; Porcelain powder (or glass-cermic powder) 0～30%; Flyash 0～30%; Also can not add flyash, make the present invention behind the various oven dry powder uniform mixing.The present invention can with acid-resisting aggregate (above-mentioned gross weight) 3～4: 6～7, amount of water is that unsetting acid resisting materials such as acid resisting concrete, acid resisting mortar and acid resistant adhesive mortar are made in 18～25% mixing of gross weight respectively. after replacing with modified powdery sodium silicate as powdery sodium silicate, other powder composition constant rate mixes product of the present invention then.Be about to touch the modified powdery sodium silicate 20～70% of several M=2.3-3.0; Silicon ash 1～30%; Bonding clay 0～30%; Porcelain powder (or glass-cermic powder) 0～30%; Flyash 0～30% (can not add), by the gross weight of said ratio can with acid-resisting aggregate weight proportion 3～4: 6～7,18～25% water that add above-mentioned material gross weight then stir into indefinite form acid resisting materials such as acid resisting concrete, acidproof mortar, acid resistant adhesive mortar.
The invention has the advantages that: owing to contained composite granule air-setting wedding agents such as modified powdery sodium silicate, silicon ash, bonding clay and flyash in the powder thing of the present invention, avoided the formulated of modified water glass, so just make transportation, store conveniently, avoided the environmental pollution of water glass simultaneously.The long quality-guarantee period of this product (above 1 year), easy to use, construction technology is simple, and accelerating construction progress improves the quality of products effectively.Because of can directly adding various acid-resisting aggregates, this product is mixed with indefinite form acid resisting materials such as acid resisting concrete, acidproof mortar, acid resistant adhesive mortar; Replace traditional acid-proof cement with product of the present invention, preparation the said products needn't add liquid water glass (water glass); Adopt the composite granule wedding agent, the use properties of product is greatly improved; So, be the renewal product of ambiguity binder for fire-resistant materials.
Embodiment:
