Wall putty powder is compared, and the present invention has highly dynamic cracking resistant, while by being modified processing to flyash, being effectively increased
The specific surface area of flyash improves its physical property；By the way that modified coal ash is added as raw material, energy conservation and environmental protection reduces
Environmental pollution, while using the volcano ash effect of flyash, be conducive to the mechanical performance for improving powder of lacquer putty for use on.
In addition, as can be seen that the present invention passes through hypersthene and fire from the data comparison of embodiment 7 and comparative example 1-4
Mountain stone cooperates, and plays synergistic effect, can effectively improve its dynamic cracking resistance.
1 testing result table of table
| Group | Dynamic cracking resistance/mm | Adhesive force grade |
| Embodiment 7 | 0.08 | 5B |
| Comparative example 1 | 0.20 | 4B |
| Comparative example 2 | 0.21 | 3B |
| Comparative example 3 | 0.17 | 2B |
| Comparative example 4 | 0.19 | 3B |
Note: corresponding adhesive force grade classification in table 1 are as follows: 5B- falls off without exterior wall, 4B- exterior wall falls off, and the gross area is less than
5%, 3B- exterior wall fall off the gross area between 5%-15%, 2B- exterior wall fall off the gross area between 15%-35%, 1B-
Exterior wall fall off the gross area between 35%-65%, OB- exterior wall fall off the gross area greater than 65%.
As can be seen that putty powder for exterior wall prepared by the present invention has highly dynamic cracking resistant, the present invention from result above
It is cooperated by hypersthene and pelelith, plays synergistic effect, its dynamic cracking resistance can be effectively improved,
Solves the excessive dynamic cracking resistance that the inorganic powdered fillers such as attapulgite, bentonite, calcium carbonate are added and are easy to cause putty layer
Property decline the problem of；Meanwhile by the way that modified coal ash is added as raw material, energy conservation and environmental protection reduces environmental pollution, utilizes fine coal
The volcano ash effect of ash is conducive to the mechanical performance for improving powder of lacquer putty for use on, has a vast market foreground.
Better embodiment of the invention is explained in detail above, but the present invention is not limited to above-mentioned embodiment party
Formula within the knowledge of one of ordinary skill in the art can also be without departing from the purpose of the present invention
