Embodiment 1
[0026] An environmentally friendly waterproof plugging material, made of the following raw materials in parts by weight: 50 parts of silicate, 15 parts of aluminate, 40 parts of redispersible rubber powder, 15 parts of quartz sand, 20 parts of paris plaster powder, 1 part of coagulant, 1 part of additive. The silicate is ordinary Portland cement, the aluminate is calcium aluminate, the retarder is citric acid, and the additive is modified graphene powder.
[0027] The modified graphene powder is prepared according to the following steps:
[0028] Step 1, weigh each raw material component according to the following mass ratio: calcium carbonate 1g, ammonium persulfate 0.2g, graphene powder 10g, water to 1L;
[0029] Step 2, mix the weighed calcium carbonate, water, and graphene powder, react at 85°C for 0.5h under stirring, then add the weighed ammonium persulfate, reflux in a water bath at 95°C for 20min, cool to room temperature, filter, and dry Dry solid to obtain modified...
