Abstract
The invention relates to a preparation method of an environment-friendly dry powder pointing agent taking slag powder as main raw materials, belonging to the technical field of building material preparation processes. The environment-friendly dry powder pointing agent comprises the raw materials in percentage by weight: 55-75 percent of slag powder, 2-10 percent of cement, 10-30 percent of calcite powder, 2-5 percent of re-dispersible emulsoid powder and 0.05-0.3 percent of thickening agent. The environment-friendly dry powder pointing agent has good caking property, good durability and high antiseepage grade, is not in contact with a tapestry brick, generates no cracks, and can effectively inhibit saltpetering. The invention widens a new approach for the resource utilization of the slag powder and has better social efficiency and economic benefit.
Description
Technical field
The present invention relates to a kind of is the preparation method of the environment-friendly dry powder pointing agent of main raw material with the slag micropowder, belongs to material of construction fabricating technology field.
Background technology
The tile pointing agent claims that again spackling and caulking agent are the joint fillers that is used to fill slit between ceramic tile or stone material, and the facing that provides attractive in appearance and guarantee bonding and antiseepage between the facing tile matches with finishing material such as ceramic tile, stone materials.Along with the fast development of Building Trade in China, more and more higher to the requirement of tile pointing agent, consumption is also increasing.In the raw material of jointing agent, cement is an indispensable part.Yet cement is big because of its rigidity, fragility is alkaline strong, occurs the crack and the accumulation of salt in the surface soil easily, causes infiltration and variable color.Therefore releasing and utilize industrial residue to produce the problem of jointing agent, is the needs of solid waste resource recovery and recycling economy, also is the needs of jointing agent Materials science development.Researcher is utilizing slag micropowder as main raw material at present, prepares environment-friendly dry powder pointing agent.
Summary of the invention
The purpose of this invention is to provide a kind of is the preparation method of the environment-friendly dry powder pointing agent of main raw material with the slag micropowder.
The present invention is a kind of to be the preparation method of main raw material with the slag micropowder, it is characterized in that having following process and step:
A. design determines that the raw material of jointing agent is formed and weight percent is:
Slag micropowder 55～75%;
Cement 2～10%;
Calcite in powder 10～30%;
Redispersable latex powder 2～5%;
Thickening material 0.05～0.3%;
The chemical ingredients of described slag micropowder is: (wt%)
SiO
230.5, Al
2O
313.9 CaO 40.9, MgO 8.6, Fe
2O
30.4, TiO
20.7 MnO 0.2, P
2O
50.05 S 2.5; Specific surface area 〉=500m
2/ kg;
Described cement is commercially available 42.5 grades of ordinary Portland cements;
Described calcite in powder, its fineness are 100～150 orders;
Described redispersable latex powder is any in styrene-propene yogurt rubber powder, acrylate latex powder, the vinyl acetate-ethylene latex powder; Its fineness is 100 orders;
Described thickening material is any in Natvosol, hydroxyethylmethyl-cellulose, the hydroxypropylcellulose;
B. press above-mentioned raw materials prescription weigh batching,, above-mentioned each raw material is put into mixing machine successively close, after fully mixing, promptly get the environment-friendly dry powder pointing agent that can suppress the accumulation of salt in the surface soil by the traditional technology method.
When granulated blast-furnace slag is iron work ironmaking, the waste residue that from blast furnace, produces.Granulated blast-furnace slag and cement are more approaching on main component, and its main chemical compositions is SiO
2, CaO, Al
2O
3, MgO, Fe
2O
3Deng, have the potential activity, after levigate, the slag activity is brought into play.Can be used to replace part cement.The specific surface area of the blast-furnace cinder micro-powder after levigate is generally at 400～600m
2/ kg, more less than the particle of 30 μ m, size-grade distribution is optimized, and after cement mixing, the further density of refinforced cement slurry has been improved the impermeability of cement.Slag is prepared the tile pointing agent as main raw material, can obviously suppress the accumulation of salt in the surface soil and variable color.Consider that from environment, technology, economical effectiveness equal angles it is coming that breeze is carried out recycling.
Characteristics of the present invention and advantage are as follows:
(1), the environment-friendly dry powder pointing agent cohesiveness that makes of the present invention is good, can closely contact with facing tile, do not produce the crack.Its good endurance, impervious grade height, effectively waterproof.
(2), the present invention is because to adopt ironmaking waste residue slag micropowder be main raw material, so cost is low, and production technique is simple, helps suitability for industrialized production and applies.
(3), cement industry is the industry of the unsustainable development of heavily contaminated, it is main raw material that the present invention adopts slag micropowder, can reduce the consumption of cement, prepares a kind of high-performance environmentally-friendly type dry powder pointing agent, it can effectively suppress the accumulation of salt in the surface soil.
(4), the present invention adds the thickening material of significant quantity, has water retaining function, and can strengthen anti-the contraction and splitting resistance, improves the thixotropy and the sag resistance of product, plays certain thickening power.
Embodiment
After now specific embodiments of the invention being described in.
Embodiment 1: proportioning at first in accordance with regulations takes by weighing 10kg42.5 level ordinary Portland cement, slag micropowder 60kg, calcite in powder 25.9kg, redispersable latex powder 4kg and thickening material 0.1kg, above-mentioned admixtion is put into mixing machine, after fully mixing, can obtain environment-friendly dry powder pointing agent.
Embodiment 2: proportioning at first in accordance with regulations takes by weighing 42.5 grades of ordinary Portland cements of 3kg, slag micropowder 75g, calcite in powder 19.3kg, redispersable latex powder 2.5g and thickening material 0.2g, above-mentioned admixtion is put into mixing machine, after fully mixing, can obtain environment-friendly dry powder pointing agent.
