High-temperature amorphous nano refractory thermal insulation material and preparation method thereof
The invention discloses a high-temperature amorphous nano refractory thermal insulation material and a preparation method thereof. The high-temperature amorphous nano refractory thermal insulation material comprises 10-40% of nano silicon dioxide, 5-25% of nano quartz sand, 10-45% of nano aluminum hydroxide, 15-80% of nano artificial powder, 20-40% of water glass, 5-15% of perlite, 15-70% of nano calcium carbonate and 2-10% of an inorganic forming agent. The nano artificial powder is artificial stone powder with high temperature resistance and weathering resistance and is prepared by homogenizing and grinding magnesium oxide and calcium oxide in water, and the weight ratio of the magnesium oxide to the calcium oxide to the water is 20: 15: 350; the inorganic forming agent is high-silica chopped fiber. The preparation method has the beneficial effects that the raw materials are easy to obtain, the preparation process is simple, construction is convenient, industrial production and application are facilitated, the long-term hot surface use temperature of the material can reach 1100-1300 DEG C, and the material is an amorphous material at normal temperature and can also be made into a plate, brick or strip shape, so that the nano refractory thermal insulation material can be widely applied to thermal equipment.
