Embodiment 1
[0009] Take the production of 100 energy-saving leveling putty powders as an example. The processed raw materials are selected. The proportions by weight of the ingredients are: 425# white cement 28%, gray matter calcium powder 7%, heavy calcium carbonate powder 51%, 80 mesh polystyrene Granules 9%, 2mm polypropylene fiber 0.5%, polyvinyl alcohol 0.9%, carboxymethyl cellulose 1.1%, polymer powder 2.5%.
[0010] Put about half of the amount of white cement, gray calcium powder, heavy calcium carbonate powder and polystyrene particles into the container, and stir for 10 minutes; then add polypropylene fiber, polyvinyl alcohol, carboxymethyl cellulose and polymer powder, after stirring for 10 minutes; then add the remaining white cement, gray calcium powder, heavy calcium carbonate powder and polyphenylene particles, continue stirring for 30 minutes to discharge the material, pack it into a bag after exhaust, and weigh it according to the bagging standard seal. The putty powder ...
Embodiment 2
[0015] According to the same process of the previous example, and according to the ratio range of the following preferred raw materials, the raw materials are mixed and stirred, wherein 28% of 425# white cement, 8% of gray matter calcium powder, 55% of heavy calcium carbonate powder, 55% of 70 mesh vitrified microspheres %, 0.6% of 2mm polypropylene fiber, 0.7% of polyvinyl alcohol, 0.8% of carboxymethyl cellulose, and 1.9% of polymer powder.
[0016] A kind of energy-saving leveling putty powder of the present invention is prepared according to the preparation method, and its performance indicators are as follows:
