Abstract
The invention discloses a heat preservation material with an anti-corrosion function, which belongs to the field of inorganic heat preservation materials, and comprises inorganic acid, acid salt, natural mineral powder, porous carbon materials, waste lithium iron phosphate anode material acid leaching residues, foam stabilizer, and a component A and a component B which are prepared from hydroxide, alkaline oxide, silicate, titanium dioxide, carbonate, foam stabilizer and deionized water.
Description
Technical Field
The invention relates to a heat preservation material, a preparation method and a use method thereof, in particular to a heat preservation material with an anti-corrosion function, and belongs to the field of inorganic heat preservation materials.
Background
The heat insulating material is one with heat coefficient lower than or equal to 0.12W/m.k and may be used widely in house, building, aviation, chemical pipeline, heating pipeline, etc. Compared with an organic heat-insulating material, the inorganic heat-insulating material has the characteristics of better heat resistance, incombustibility and the like, and if the inorganic heat-insulating material is applied to the heat insulation of an outer wall, the ultraviolet resistance of the inorganic heat-insulating material is better than that of the organic heat-insulating material, and the inorganic heat-insulating material can be used for the heat insulation of the outer wall for a long time in places with strong ultraviolet radiation such as a plateau, ocean and the like; in the aspect of heat preservation of chemical pipelines and heating pipelines, the inorganic heat preservation material has better high temperature resistance and aging resistance effect than the inorganic heat preservation coating.
Patent CN108003410a discloses a heat-insulating building material, which contains high polymers such as rubber and hydroxypropyl cellulose, so that the heat-insulating material is not resistant to ultraviolet rays and high temperature in the use process and is easy to age. In addition, the heat insulation material is combined with metal without chemical bonds, and cannot provide good anti-corrosion protection for metal parts used outdoors.
Disclosure of Invention
In view of the above, the invention provides a heat insulating material with an anti-corrosion function, and a preparation method and a use method thereof, so that the heat insulating material has the anti-corrosion function on a metal structure while providing heat insulating performance.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
a heat insulation material with an anti-corrosion function comprises a component A and a component B in a mass ratio of 0.5-1:1;
the component A comprises the following raw materials in parts by weight:
20-60 parts of inorganic acid and acid salt;
10-20 parts of natural mineral powder;
0-5 parts of porous carbon material;
2-10 parts of acid leaching residues of waste lithium iron phosphate anode materials;
0.1-1 part of foam stabilizer;
10-30 parts of deionized water;
the component B comprises the following raw materials in parts by weight:
15-35 parts of hydroxide and alkaline oxide;
10-20 parts of silicate;
1-3 parts of titanium dioxide;
