Background
The putty powder is one kind of building decoration material and has talcum powder and glue as main components. The putty is a base material for repairing and leveling the wall surface, and lays a good foundation for the next step of decoration (painting and wallpaper pasting). The putty is divided into an inner wall and an outer wall, and the putty for the outer wall has large adhesiveness, high strength and slightly low environmental protection index because the putty for the outer wall resists wind, wind and sun. The interior wall putty has better comprehensive index, is healthy and environment-friendly, so the interior wall is not externally used, and the exterior wall is not internally used. Typically, the putty is gypsum or cement based so that the surface roughness is easier to bond firmly. However, during construction, a layer of interface agent is coated on the base layer to seal the base layer and improve the adhesion of the wall surface, so that the putty can be better bonded on the base surface.

Especially, most of the buildings adopt reinforced concrete integral filling structures or light materials produced by industrial bottom slag at present. The wall surface must be finished and smoothed before being painted, which requires the use of a large amount of putty powder. However, the cement filling structure and the wall surface are smooth, so that the difficulty of combining the putty powder with the wall surface is high. The adhesive force and the washing resistance of the putty powder need to be improved so as to ensure the construction quality of the putty powder.
The putty powder in the prior art has the problems of environmental pollution, low strength, poor water resistance and the like, so that the further market promotion strength of the putty powder is influenced.

In the prior art, putty powder is one of building decoration materials, and the main components are talcum powder and glue. The putty is a base material for repairing and leveling the wall surface, and lays a good foundation for the next step of decoration (painting and wallpaper pasting). The putty is divided into an inner wall and an outer wall, and the putty for the outer wall has large adhesiveness, high strength and slightly low environmental protection index because the putty for the outer wall resists wind, wind and sun. The interior wall putty has better comprehensive index, is healthy and environment-friendly, so the interior wall is not externally used, and the exterior wall is not internally used. Typically, the putty is gypsum or cement based so that the surface roughness is easier to bond firmly. However, during construction, a layer of interface agent is coated on the base layer to seal the base layer and improve the adhesion of the wall surface, so that the putty can be better bonded on the base surface.
With the improvement of living standard, people have higher and higher requirements on the environment of a living room, and the level of indoor decoration and decoration is higher and higher. Especially, most of the buildings adopt reinforced concrete integral filling structures or light materials produced by industrial bottom slag at present. The wall surface must be finished and smoothed before being painted, which requires the use of a large amount of putty powder. However, the cement filling structure and the wall surface are smooth, so that the difficulty of combining the putty powder with the wall surface is high. The adhesive force and the washing resistance of the putty powder need to be improved so as to ensure the construction quality of the putty powder.
The further market promotion strength of the common putty powder on the market is influenced due to the problems of poor environmental protection, low strength, poor water resistance and the like.
In order to solve the technical problems, the invention provides the putty powder with high water resistance for the interior and exterior walls, the putty powder contains raw materials, sulphoaluminate cement and black cement are used as main materials, the effect of ensuring the strength of the putty powder for a long time is mainly achieved, the water resistance of quartz sand is very good, and a great amount of practices show that 80-mesh quartz sand is necessarily adopted to be compatible with other components, the water resistance effect is affected if the mesh size is too large or too small, the later service life and the service performance are affected if the water resistance is not good, and the later-stage service life and the later-stage service performance are affected if the mesh size is too large or too small.
The grade of the black cement is not particularly limited, and the black cement is within the scope of the present invention.
In other components added in the preparation of the putty powder, calcium chloride has a hardening acceleration effect, lithium chloride plays a role in curing, zinc stearate is a heat stabilizer, cellulose is added to increase viscosity, sodium hexametaphosphate plays a role in dispersing, talcum powder, wollastonite powder and titanium dioxide are added to serve as reinforcing fillers, and the concrete selection of the water reducing agent can be an FD-N-S early-strength water reducing agent or a UNF-4 early-strength water reducing agent, and is not particularly limited.
The heavy calcium powder is an excellent filler, and the reasonable compatibility of the heavy calcium powder and other components can improve the compressive strength, the flatness, the water absorption and the water-resistant effect of the putty powder.
In addition, in order to improve the solubility of the putty powder, increase the flexibility and simultaneously ensure the required viscosity, the putty powder also additionally adds the double-flying powder, the rubber powder and the sierozem powder, and after the three components are added, the putty powder shows super-strong cohesiveness.
In order to improve the excellent compatibility among the components, the components are preferably prepared according to the following mixture ratio: 780 parts of sulphoaluminate cement 770-activated carbon, 12-18 parts of black cement, 180 parts of 80-mesh quartz sand-activated carbon, 13-14 parts of calcium chloride, 7-7.5 parts of lithium chloride, 5-6 parts of talcum powder, 5-7 parts of zinc stearate, 5-6 parts of hydroxypropyl methyl cellulose, 5-7 parts of a water reducing agent, 4-5 parts of wollastonite powder, 1.2-1.5 parts of titanium dioxide, 7-10 parts of sodium hexametaphosphate, 72-78 parts of heavy calcium powder, 42-48 parts of calcium carbonate powder, 2.2-2.8 parts of rubber powder and 6-8 parts of sierozem powder.
More preferably, 775 parts of sulphoaluminate cement, 16 parts of black cement, 160 parts of 80-mesh quartz sand, 13 parts of calcium chloride, 7 parts of lithium chloride, 5 parts of talcum powder, 6 parts of zinc stearate, 6 parts of hydroxypropyl methyl cellulose, 6 parts of a water reducing agent, 4.5 parts of wollastonite powder, 1.3 parts of titanium dioxide, 8 parts of sodium hexametaphosphate, 75 parts of heavy calcium powder, 46 parts of calcium carbonate powder, 2.5 parts of rubber powder and 7 parts of sierozem powder.
It should be noted that 5-7 parts of diatom ooze is creatively added into the formula of the putty powder, the diatom ooze can improve the weather resistance of the putty powder, so that the putty powder is not easy to mildew and crack, and after the diatom ooze is added and matched with main materials of black cement and sulphoaluminate cement together, the curing performance of the putty powder can be obviously improved, and the stability of the putty powder is enhanced. The putty powder has the advantages that 5-8 parts of magnetic conduction filler can be added, the phenomenon of cracking caused by too large temperature difference change can be avoided due to the addition of the magnetic conduction filler, the weather resistance of the putty powder is further improved, the magnetic conduction filler has the effect of absorbing electromagnetic radiation, some magnetic particles in the air can be adsorbed, a certain radiation absorption effect is realized in a relatively large environment with radiation, the radiation damage to human bodies is avoided, and the putty powder is more green and environment-friendly.
The magnetic conductive filler adopted by the invention can be iron powder, magnetic powder and the like, and any product capable of adsorbing magnetic substances is within the protection scope of the invention.
The putty powder prepared after compatibility can have good construction performance only if the addition amount of each component shows certain regularity, and in addition, a key factor which needs to be considered when the addition amount is optimized is the problem of addition cost because, for example, the addition amount of cement has a relatively proper addition range after practice, the putty powder is more easy to crack under the condition that the cement is excessively added, the strength of the putty powder is not remarkably increased, the effect is basically balanced, the addition amount of the cement is increased at the moment, rather, the cement is not economical, and the product quality is influenced to a certain extent.
Similarly, in the process of blending, granular materials such as quartz sand, double flying powder, rubber powder, heavy calcium powder and the like are easy to be bonded due to mutual contact and permeation of the surfaces under the hydration action of the surfaces, so that the granular materials are easy to agglomerate together, and the strength of the putty powder is very unfavorable after the agglomeration is formed, so that the problem that the agglomeration of the putty powder is influenced due to the fact that the addition amount of the granular materials is not too large is also considered fully, and the addition amount of other components is also controlled within a proper range because the components have a certain interaction relationship.
The putty powder has the most remarkable advantage of high water resistance, so that the putty powder achieves excellent water resistance by selecting specific components and matching with specific addition, and each component can form stronger association with water molecules after reasonable compatibility to form a space net structure so as to achieve good water resistance.
In other components for reinforcing, filling and binding, the addition amount needs to be paid attention, and if the addition amount is too large, the strength of the putty powder per se can be unstable, so that the addition amount needs to be reasonably controlled.
In a word, in the preparation process, in order to obtain the putty powder with high water resistance for both internal and external walls, the applicant determines the regulation and control of the whole formula after a large amount of practice, and needs to pay attention to the selection of each component and the control of the specific addition amount, so as to ensure the excellent quality of the putty powder.
The invention provides the putty powder for the interior and exterior walls with high water resistance and a preparation method thereof, and the preparation method specifically comprises the following steps:
