[0026] Example 1:
[0027] A new type of energy-saving and environmentally-friendly waterproof plaster and its preparation method. Taking 100kg of dry powder of new-type energy-saving and environmentally-friendly waterproof plaster as an example, the content of each component is as follows:
[0028]
[0029] Natural gypsum is made of natural gypsum stone through calcination, grinding, whitening, roasting and other technological processes, and the screening fineness is 160 mesh;
[0030] Quartz sand is natural quartz stone that has been crushed, finely ground, and screened with a fineness of 60 mesh;
[0031] The ash slag is the waste slag of the power plant boiler. After desulfurization, it is magnetically separated by a magnetic separator, and then processed by fine grinding. The screening fineness is 60 mesh;
[0032] Calcium increasing agent, the main components of calcium hydroxide and calcium oxide, the proportion of calcium hydroxide and calcium oxide is 1:0.2;
[0033] The waterpr...
