Embodiment 1

[0025] A preparation process of an anti-dye powder paste comprises: materials and processes;

[0026] The materials include the following:

[0027] S1. Raw materials: cementitious materials, fillers, additives, auxiliary materials and water; activated calcium carbonate, bentonite, polyvinyl alcohol, cellulose ether, sodium hexametaphosphate and water;

[0028] S2. The proportion of the cementitious material is 5%, the proportion of the filler is 95%, the proportion of the auxiliary agent is 9.3%, and the proportion of the auxiliary material is 2.2% %, and the proportion of the water is 55%.

[0029] The cementitious material is an emulsion, and the emulsion has many characteristics such as high bonding strength, water resistance and environmental protection.

[0030] The fillers are heavy calcium carbonate, light calcium carbonate and talc, the content of the heavy calcium carbonate is 65%, the content of the light calcium carbonate is 10%, and the talc is The proportion of...

Embodiment 2

[0043] A preparation process of anti-dye powder paste comprises the following steps:

[0044] The first step: select the emulsion as the cementitious material, and the amount of the cementitious material is 10%, and then add the filler to mix and stir evenly, and the time is 5-10min;

[0045] The second step: the auxiliary agent is added to the first step, and then mixed and stirred for 10 to 15 minutes;

[0046] The third step: add the auxiliary materials into the second step, and then mix and stir until there is no agglomeration, resulting in putty powder;

[0047] Step 4: Mix and stir the putty powder and water until the putty powder becomes a powder paste.

[0048] The type and amount of cementitious material have the most obvious influence on the bonding strength and water resistance of putty. The bonding strength of putty increases with the increase of the amount of cementitious material. However, if the amount is too large, it will affect the sandability, and it is not...

Embodiment 3

[0050] A preparation process of anti-dye powder paste comprises the following steps:

[0051] The first step: select the emulsion as the cementitious material, and then add the filler to mix and stir evenly, the time is 5-10min;

[0052] The second step: adding the auxiliary agent into the first step, and then mixing and stirring for 10 to 15 minutes, and the proportion of suspending agent-bentonite in the auxiliary agent is 0.7%;

[0053] The third step: add the auxiliary materials into the second step, and then mix and stir until there is no agglomeration, resulting in putty powder;

[0054] Step 4: Mix and stir the putty powder and water until the putty powder becomes a powder paste.

[0055] According to the content of different anti-settling agents to observe the state of the putty, it is found that when the content is low, delamination is easy to occur in a short time, and when the content is too large, although there is no delamination, the cost is too high, which affe...

Abstract

The invention provides a preparation process of dye-resistant powder paste. The preparation process of the dye-resistant powder paste comprises the following steps: preparing materials and working procedures; the material comprises the following raw materials: S1, a cementing material, a filler, an auxiliary agent, an auxiliary material and water; the coating is prepared from activated calcium carbonate, bentonite, polyvinyl alcohol, cellulose ether, sodium hexametaphosphate and water. S2, the doping amount of the cementing material accounts for 5%, the doping amount of the filler accounts for 95%, the doping amount of the auxiliary agent accounts for 9.3%, the doping amount of the auxiliary material accounts for 2.2%, and the doping amount of the water accounts for 55%. The preparation technology of the dye-resistant powder paste has the advantages of being excellent in performance, good in water resistance and batch scraping performance, stable in quality, low in cost and the like, particularly has the characteristics of being good and the like, and has the advantages of being firm in bonding strength and firm in adhesive force.

Description

technical field [0001] The invention belongs to the technical field of powder paste preparation technology, and particularly relates to a preparation process of anti-dye powder paste. Background technique [0002] Putty powder has been widely used in recent years, and the variety of putty powder is now very complete, such as ordinary interior and exterior wall putty, water-resistant interior wall putty, exterior wall putty, and high-viscosity strength putty for the surface of old tiles. The performance of the putty can meet the quality requirements of the corresponding national standards or industry standards and the requirements of the mandatory national standard GB18582-2001. Among them, the exterior wall putty has high requirements for corrosion resistance due to its long-term outdoor environment. The existing method for preparing exterior wall putty powder with high corrosion resistance is usually divided into mixed solids and mixed liquids for deployment in different pr...
