Every 1t of PVC is produced, 1.5-1.9 t of carbide slag can be discharged at the same time. Because the carbide slag has large yield and strong alkalinity, if the carbide slag is not recycled and is stacked or buried in the open air, a large amount of land resources are occupied, and secondary pollution is generated to peripheral soil and water bodies.

Detailed Description
Hereinafter, the alkali-return-resistant finishing integrated material and the wall color finishing method according to the present invention will be described in detail with reference to the accompanying drawings and exemplary embodiments.
One aspect of the invention provides an alkali return resistant plastering and decorating integrated material. In an exemplary embodiment of the alkali-return-resistant plastering and decorating integrated material, the material can comprise, by weight, 100-240 parts of carbide slag, 40-150 parts of cement, 680-790 parts of sand, 10-20 parts of filler, 0.01-0.1 part of air entraining agent, 0.2-2.0 parts of thickening and water retaining agent, 1.0-4.0 parts of water repellent and 0.1-10.0 parts of color pigment. Further, the material comprises, by weight, 100-240 parts of carbide slag, 40-50 parts of cement, 680-790 parts of sand, 10-20 parts of filler, 0.01-0.1 part of air entraining agent, 0.2-2.0 parts of thickening and water retaining agent, 1.0-4.0 parts of water repellent and 0.1-10.0 parts of color pigment.
Above, in one aspect, the material of the present invention has excellent alkali-return resistance. The alkali-return resistance of the material can be realized by the carbide slag containing specific components and the water repellent together. Specifically, the main components of the carbide slag can generate carbonation reaction in the air, the generated product calcium carbonate can block a channel for the soluble alkali generated in the cement hydration process to migrate to the surface of the facing material, and the distribution of the internal pore structure of the facing material can be changed, so that the migration channel of the soluble alkali is more complicated, and the effect of inhibiting alkali return is finally achieved. In addition, the water repellent with the component content can optimize the internal pore structure of the material, so that water vapor molecules can freely enter and exit, and macromolecular water molecules cannot pass through, thereby enhancing the water repellent effect of the material and avoiding the occurrence of alkali return.
On the other hand, the material has the performance of finishing the integration of plastering, water proofing, decoration and protection by one-time construction due to the contained components and the specific content proportion among the components. The material can be constructed on the wall surface at one time, and integrates the steps of leveling, waterproofing, decoration protection and the like to be completed in one step, so that the maintenance period of waiting of each layer is avoided, the time is greatly shortened, the labor cost is saved, and hollowing and cracking caused by inconsistent shrinkage or expansion stress among the layers are avoided.
In another aspect, the material of the present invention has good air permeability, and the air permeability coefficient of the material of the present invention is above 1.5Ln/min (pressure/min).
In the embodiment, the air entraining agent is added in an amount of 0.01-0.1 part, and a proper amount of bubbles can be introduced into the material, so that the workability of the freshly-mixed material can be further improved, the friction force in the material is reduced, and the freeze-thaw resistance and the durability of the hardened material are remarkably improved. The air entraining agent added in an amount exceeding the upper limit of the range can cause the material structure of the invention to be loose and the strength to be seriously reduced. Lower limits below the above range will affect the workability of the material, and affect the long-term durability and stability of the structure. Further, the addition amount of the air-entraining agent may be 0.05 part.
In the embodiment, the addition amount of the thickening water-retaining agent is 0.2-2.0 parts, so that the thickening water-retaining agent can play roles in thickening, water retaining, sagging resistance, construction performance improvement and the like in the material. The addition amount of the thickening and water-retaining agent exceeding the upper limit of the range causes the material of the invention to be difficult to construct and increases the difficulty of manual or mechanical operation. When the lower limit is lower than the lower limit, the cohesive force of the fresh mixing material is reduced, and the fresh mixing material is easy to fall down and fall off after being hung on a wall. Further, the addition amount of the thickening water retention agent can be 1.2 parts.
In the embodiment, the addition amount of the water repellent is 1.0-4.0 parts, so that the internal pore structure of the mortar can be optimized, water vapor molecules can freely enter and exit, and water molecules of macromolecules cannot pass through, the water repellent effect of the mortar is enhanced, and the occurrence of alkali return is avoided. If the addition amount of the water repellent exceeds the upper limit of the above range, the material is difficult to stir uniformly, the early hydration degree is slow, and the strength is low. Below the lower limit, the water absorption of the material increases and the durability decreases. Furthermore, the adding amount of the water repellent is 2.2 parts.
In this embodiment, the mass ratio of the carbide slag to the cement may be 0.7 to 1.5 or 4.8 to 6.0. The air permeability and strength of the material of the invention can be affected by the ratio of the carbide slag to the cement. In order to meet different facing requirements of a wall, for example, when good air permeability is needed but the strength requirement is not high, the mass ratio of the carbide slag to the cement can be set to be 4.8-6.0, for example, 4.8-5.2. When the facing material with good strength requirement but low air permeability requirement is required, the mass ratio of the carbide slag to the cement can be set to be 0.7-1.5. For example, the mass ratio of the carbide slag to the cement may be set to 1.0 to 1.4. Furthermore, in order to enable the material to have both good strength and good air permeability, the mass ratio of the carbide slag to the cement can be 0.9-1.1. Furthermore, the mass ratio of the carbide slag to the cement can be 1: 1.
In this embodiment, the carbide slag may be dry carbide slag or wet carbide slag. The moisture content of the wet carbide slag can be 5-40%. For example, it may be 20% to 35%. The dry carbide slag can be obtained by drying for 24 hours or more than 24 hours at the temperature of 105 +/-5 ℃, cooling to room temperature, and then grinding for 10 minutes or more than 10 minutes by using a ball mill.
In this embodiment, the carbide slag may include, by weight, 81.20% -87.19% of CaO and Fe2O37.89％～9.99％，SiO22.58％～5.24％，Al2O30.58％～3.40％，SO30.35％～0.91％，TiO20.34-0.83 percent of MgO, 0.05-0.14 percent of MgO. Further, the material can comprise 83.19% of CaO and Fe by mass percentage2O39.99％，SiO23.24％，Al2O31.40％，SO30.71％，TiO20.63％，MgO 0.14％。
In this embodiment, the cement may be one or a combination of two or more of portland cement, oil well cement, white portland cement, aluminate cement, and sulphoaluminate cement.
In this embodiment, the color pigment may be one or a combination of two or more of inorganic iron oxide red, iron oxide yellow, iron oxide black, iron oxide brown and titanium dioxide. The alkali-return-resistant plastering and decorating integrated material is mainly suitable for the colored veneer of a wall. The colored wall body has excellent performances of stain resistance, good look and the like, and the white wall body in practical application is not suitable for large-scale popularization because of the limitation of no stain resistance, aesthetic factors and the like.
In this embodiment, the filler may be one or a combination of two or more of limestone powder, fly ash, slag powder, silica fume and metakaolin.
In this embodiment, the air-entraining agent may be one or a combination of two or more of alkyl sulfonate, alkyl benzene sulfonate, rosin soap and modified products, alkylphenol ethoxylates, polyethers, sodium saturated or unsaturated fatty acids, and protein hydrolysates.
In this embodiment, the thickening and water-retaining agent may be one or a combination of two or more of polyvinyl alcohol, cellulose ether and its derivatives, polyacrylic acid, water-soluble starch, carboxymethyl cellulose, polyacrylamide, and polyvinyl pyridine.
In this embodiment, the water repellent may be one or a combination of two or more of stearate, organosilicon water repellent, sodium silicate, polysiloxane, and sodium methylsiliconate.
In another aspect of the invention, a method for decorating a wall in color is provided. In an exemplary embodiment of the wall color finishing method, the finishing method may stir the alkali-return resistant finishing integrated material as described above to a uniform non-blocking state; curing, scraping and smearing the cured plastering and decorating integrated material on the wall body in batches, and smearing the plastering and decorating integrated material after the preset thickness is reached to finish the colorful wall facing.
Further, the finishing method can comprise the steps of stirring the plastering and decorating integrated material to be uniform and free of agglomeration, and curing the plastering and decorating integrated material for 5-10 min for reuse. Scraping and coating the stirred plastering and decorating integrated material on a pretreated (cleaned adhesive and wetted by water) outer wall in a mechanical spraying or manual construction mode, leveling the material by using a spatula until the thickness reaches a certain thickness (1-2 cm), and modeling the wall by using a special tool when the plastering and decorating integrated material begins to be initially set after 4-6 hours.
In an exemplary embodiment of the wall color finishing method of the present invention, the predetermined thickness may be 1cm to 2 cm. For example, the predetermined thickness may be 1.8 cm.
