Building putty is a very important supporting material for architectural coatings. For a long time, in my country's construction projects, architectural putty mainly refers to the inner wall putty, and the development of the external wall putty products is relatively small. The relevant standards of domestic external wall putty are still brewing. At present, there are some single -group powder -shaped products on the external wall putty, but in order to achieve the intensity required for the external wall putty, it is generally mixed with a large amount of cement. Therefore, its construction performance is poor, the batch is difficult, and the cost is relative to the inner wall. Putty is much higher. Therefore, it is urgent to develop a single -group dry powder outer wall putty with high intensity, good construction performance, and quality and cheap.
Gyeong and coal ash is a solid waste produced by the thermal power plant. It is an artificial volcanic gray material. At normal temperature, react with CA (OH) 2 reaction to generate compounds with gel and gel. We used flour ash as an active filler to successfully develop a high -quality and cheap dry powder outer wall putty.
In order to achieve the early intensity required for the external wall put, the grinding composite high calcium flour coal ash was selected.
The active filler uses an important role in inspiring the activity of flour ash, but also its own solidification of alkaline active substances contributed to the initial intensity of putty.
The composite excitation agent is used as a composite excitation agent.
The base material of the base material of the base material of the base material is imported with decentralized latex powder. It is made by the spraying of the tanniene -lyerene polymer emulsion with the spray. Latex powder can improve the initial adhesion, water retention, water resistance, and improve construction performance.
Other fillers are to improve the color of putty, increase the density and intensity of putty, and other fillers need to be added.
Water retention agent
The main component of the water preservation agent is cellulose ether. It can improve construction performance and benefit the hydration reaction of the active ingredients in the ash.
The process of taking dry powder on the exterior wall of the exterior wall with powder and coal ash is relatively simple. After weighing all raw materials according to the formula, it is put into the dry powder mixture in turn, and the finished product is fully mixed and evenly mixed.
