Low-thermal-conductivity heat preservation method, low-thermal-conductivity material and preparation method thereof
The invention relates to the technical field of thermal insulation material preparation, in particular to a low-thermal-conductivity thermal insulation method which comprises the following steps: covering the surface of a low-thermal-conductivity thermal insulation material with aluminum foil or tin foil, and reducing the actual thickness of the thermal insulation material; the low-thermal-conductivity thermal insulation material comprises the following components in parts by weight: 40-60 parts of vermiculite, 5-15 parts of floating beads, 3-8 parts of clay powder, 5-10 parts of alumina powder, 10-15 parts of silica powder, 10-15 parts of perlite and 3-8 parts of aluminate cement. The vermiculite is flaky vermiculite, the particle size of the vermiculite is smaller than or equal to 1.5 mmm, the particle size of the floating beads is 20-40 meshes, the particle size of the clay powder is 120-250 meshes, the particle size of the alumina powder is 160-320 meshes, the particle size of the silica powder is 180-1000 meshes, the particle size of the perlite is smaller than or equal to 1 mm, and the specification of the aluminate cement is CA-80. And the low-aluminum thermal insulation material is adopted, so that the corrosion resistance is improved while the thermal insulation effect is good, and the later maintenance cost of the electrolytic cell is greatly saved.
本发明涉及保温材料制备技术领域，具体涉及低导热保温方法，在低导热保温材料表面覆盖铝箔或锡箔，并减少保温材料的实际厚度；低导热保温材料，按照重量份数，包括：蛭石40～60份，漂珠5～15份，粘土粉3～8份，氧化铝粉5～10份，硅微粉10～15份，珍珠岩10～15份，铝酸盐水泥3～8份；所述蛭石规格为片状蛭石，且粒径小于等于1.5mmm，漂珠粒径为20～40目，粘土粉粒径为120～250目，氧化铝粉粒径为160～320目，硅微粉粒径为180～1000目，珍珠岩粒径为小于等于1mm，铝酸盐水泥规格为CA‑80。采用低铝保温材料，保温隔热效果良好的同时，提升了抗侵蚀性能，大大节约了电解槽后期的维护成本。
