Abstract

The invention relates to the technical field of building materials and aims to provide high-strength and high-toughness colored self-leveling cement. The high-strength and high-toughness colored self-leveling cement is formed by compounding Portland cement and sulfate aluminum cement to serve as a gelled material and is prepared by mixing the following raw material components: the Portland cement, the sulfate aluminum cement, quartz sand, natural colored sand, toner, mineral waste residue, fly ash, dispersible latex, a stabilizing agent and a defoaming agent. According to the high-strength and high-toughness colored self-leveling cement disclosed by the invention, the Portland cement and the sulfate aluminum cement are compounded to serve as the gelled material; self-leveling cement mortar has the advantages of good workability, high strength, small shrinkage, high toughness, low possibility of cracking and good wear resistance; the natural colored sand is used as a main aggregate, and inorganic toner is adopted as a coloring material; the self-leveling cement mortar is abundant and diversified in color, stable in luster and high in decorativeness. Equipment for preparing the product is lower in requirement and simple in operation, and is suitable for large-scale production.

Description

A kind of high-strength and high-ductility colour self-leveling cement
Technical field
The invention belongs to building material technical field, and in particular to a kind of high-strength and high-ductility colour self-leveling cement.
Background technology
Self-leveling cement is a kind of novel environment friendly product of high-tech, is into the dry-mixed type powdery being grouped into by various active Material, job site uses by mixing water.Launched using scraper when pouring, can be obtained using the flow leveling of gravity flowing levelling mortar High flat surfaces or surface layer.Setting rate is fast, and people's walking can be gone up after general 24 hours, and the paving of follow-up finish coat can be carried out immediately If or gravity flow self-leveling floor milled processed works, quick construction, simplicity.
In recent years, with China's expanding economy, what at this stage most of self-leveling cement was present is dried contraction soon, intensity Slow, season cracking is lifted, worn no resistance, the problems such as color and luster is degenerated, become increasingly conspicuous.To meet people for high-quality life water Flat requirement, it would be highly desirable to develop new self-leveling cement to solve the above problems.
The content of the invention
The technical problem to be solved in the present invention is to overcome deficiency of the prior art, there is provided a kind of high-strength and high-ductility is colored Self-leveling cement.
To solve technical problem, the solution of the present invention is:
A kind of high-strength and high-ductility colour self-leveling cement is provided, be using portland cement and sulphate aluminium cement it is compound as Binder Materials, and it is blended by the raw material components of following mass percents:
In the present invention, the portland cement be strength grade be 42.5Mpa Portland cement, the sulphur aluminic acid Salt cement is the common sulphate aluminium cement that strength grade is 42.5Mpa;According to the preferred white cement of requirement to color.
In the present invention, the quartz sand is the mountain silica sand that mesh number is 40~120 mesh;The mesh number of the natural colour sand is 10~40 mesh.The addition of natural colour sand essentially consists in the Natural color for lifting Self-leveling, Self-leveling color is more enriched and stable.
In the present invention, the slag refers to the slag for producing the raw material of ordinary cement;The flyash refers to coal Flyash in the waste solid of power plant emission.
In the present invention, the toner is the inorganic toner of iron oxide, and the addition of the serial toner essentially consists in lifting Self-leveling The stability of middle color and luster, while addition respective color toner can be needed according to different color, meets colorful gravity flow terrace and applies Work demand.The polymer dispersion powder is the polyvinyl acetate rubber powder that can be dissolved in water, and the addition of polymer dispersion powder is main It is to improve the adhesive strength of cement mortar and substrate, while the cohesive force of mortar can be lifted, finally with lifting Self-leveling Crack resistance and wearability.The stabilizer is hydroxypropyl methyl cellulose ether, can prevent cement mortar bleeding, laminated segregation, Increase the good workability of mortar acquisition and stability, and the pliability of mortar, durability is improved.The defoamer is have Machine silicon defoaming agent, improves can strength of cement mortar, and hardened mortar surface pinhole is less and smooth.
In the present invention, the preparation method of the colored self-leveling cement of described high-strength and high-ductility, is closed by the quality proportioning System is weighed after each component, successively by portland cement, sulphate aluminium cement, flyash, slag, natural colour sand, toner, quartz Sand, polymer dispersion powder, stabilizer, defoamer input mixer in, mix 5~10min, mixer rotating speed be 2000~ 2500rad/min。
Compared with prior art, the invention has the beneficial effects as follows:
(1) present invention is compound as Binder Materials, self-leveling cement mortar using portland cement and sulphate aluminium cement Workable, intensity is high, shrinks little, and toughness is high, and not easy to crack, wearability is good.
(2) present invention adopts natural colour sand as main aggregate, while using inorganic toner as coloured material, Self-leveling Cement mortar rich color is various, color stability, ornamental strong.
(3) a kind of preparation method of high-strength and high-ductility of the invention colour self-leveling cement, equipment requirement is relatively low, operation letter It is single, it is adaptable to mass produce.
