Description
Technical Field
The invention belongs to the technical field of plastering gypsum additives.
Background
The plastering gypsum is a plastering material widely applied to the wall surface of a building, and the technical requirements of the plastering gypsum are specified by the national standard plastering gypsum (GB/T28627-2012). In recent years, plastered gypsum is increasingly used. In the existing plastering gypsum, on one hand, the consumption of natural gypsum or desulfurized gypsum is large, the production cost is high, and on the other hand, the plastering gypsum has poor water resistance and weather resistance, so that the plastering gypsum can only be used indoors and cannot be used in environments with high humidity such as kitchens, toilets and the like.
In the ore dressing operation and smelting industry, a large amount of phosphorus slag can be generated, the utilization rate of the phosphorus slag is limited, a large amount of phosphorus slag is discarded, resources are wasted, and the environment is polluted. Therefore, some enterprises are continuously invested in, develop the gypsum powder capable of effectively utilizing the solid waste phosphorus slag, and the gypsum powder is used for producing plastering gypsum to meet the requirements of the building field. However, in the prior art, the plastering gypsum produced by using the gypsum powder of the solid waste phosphorous slag generally has the problems of unstable quality, low strength, poor water resistance and weather resistance, limits the application range of the plastering gypsum, and has adverse effect on the quality of the wall surface of a building.
In addition, in the prior art, when the plastering gypsum mortar is prepared, the gypsum powder and various additives are weighed on site, the used raw materials are various, the batching is complex, the operation is troublesome, and the difficulty is brought to the site raw material management. In addition, in the plastering gypsum formula in the prior art, the addition amount of the additive is less, when plastering gypsum mortar is prepared, the loss of the additive is easily caused by each operation link, the slurry hanging on the inner wall of a container and the like, and even if the loss is very small, the quality of the plastering gypsum is greatly fluctuated.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provide the high-strength water-resistant plastering gypsum synthesis agent which can effectively improve the strength, water resistance and weather resistance of solid waste phosphorite slag plastering gypsum, and has stable and reliable product quality and low manufacturing cost.
The purpose of the invention is realized by the following technical scheme:
a high-strength water-resistant plastering gypsum synthesis agent comprises, by mass, 270-330 parts of a gypsum reinforcing agent, 180-220 parts of a gypsum water-resistant agent, 12-18 parts of a gypsum retarder, 35-45 parts of a water-retaining agent, 35-45 parts of a lubricant, 55-70 parts of a shrinkage-resistant agent, 0-20 parts of an anti-sagging agent, 10-20 parts of a gypsum air-entraining agent, 135-165 parts of an expanding agent and 45-55 parts of other fillers.
The application of the high-strength water-resistant plastering gypsum synthetic agent is that the high-strength water-resistant plastering gypsum synthetic agent is added into phosphorus slag gypsum powder, and the addition of the high-strength water-resistant plastering gypsum synthetic agent is 10-20% of the mass of the phosphorus slag gypsum powder.
In the formula of the invention, the gypsum reinforcing agent can improve the strength and the surface hardness of the plastering gypsum. The gypsum water-resistant agent can form a hydrophobic film on the surface of the mortar to achieve a waterproof effect, and also has a certain air-entraining function, micro-bubble blocking pore channels are formed in the mortar to prevent water molecules from entering the mortar, so that the water resistance is further improved. The gypsum retarder can reduce the setting speed of gypsum. The water-retaining agent can prevent the plastering gypsum from drying and cracking due to too fast water loss after being plastered on the wall body, and the plastering gypsum mortar can reach necessary viscosity, thereby improving the construction efficiency. The lubricant is a thixotropic lubricant, can prolong the opening time of the plastering gypsum mortar, improve the construction lubricity, improve the thixotropy, the anti-sagging property and the yield value of the plastering gypsum mortar and reduce the resistance during flowing. The antishrinking agent is effective in controlling the dry shrinkage of the gypsum product. The anti-sagging agent can improve the anti-sagging performance of the plastering gypsum. The air entraining agent for gypsum can make plastering gypsum mortar generate micro bubbles, reduce apparent density and workability of mortar. The expanding agent can make the plastering gypsum mortar generate certain volume expansion.
The gypsum reinforcing agent, the gypsum water-resistant agent, the gypsum retarder, the water-retaining agent, the lubricant, the anti-shrinkage agent, the anti-sagging agent, the air entraining agent and the expanding agent are all mature products sold in the market directly, and other fillers usually adopt fly ash.
The invention has the following advantages:
1. the high-strength waterproof plastering gypsum synthesis agent disclosed by the invention can be directly added into industrial phosphorite slag solid waste gypsum powder to prepare plastering gypsum mortar, is convenient to use, solves the problems that the operation is complex and troublesome because gypsum powder and various additives with various types need to be temporarily weighed and proportioned in the prior art, and also solves the problem of unstable quality of plastering gypsum caused by adding and producing complex additives.
2. The plastering gypsum prepared by the high-strength waterproof plastering gypsum synthesis agent has high strength, excellent waterproof performance and good durability, is used for walls of toilets, kitchens and the like, does not absorb moisture and go moldy, and solves the problem that the existing plastering gypsum can only be used for indoor rooms and can not be used for plastering walls of toilets, kitchens, outdoors and the like due to poor strength and poor water resistance.
3. The high-strength waterproof plastering gypsum synthesis agent disclosed by the invention is large in dosage when preparing plastering gypsum mortar, can be added to 10-20% generally, and cannot cause obvious influence on the quality of plastering gypsum even if a small amount of loss is generated in the batching process.
4. The method realizes effective utilization of industrial phosphorite slag solid waste gypsum powder, changes waste into valuable, is green and environment-friendly, has low manufacturing cost, and better meets the commercialization requirement of urban plastering materials.
