Embodiment 1

[0019] Add 83 g of iron oxide powder of 325 mesh (median diameter about 47 μm), 11.6 g of glass fiber, and 870 g of pulp (17.4 g in dry weight) to 6824 g (580 g in dry weight) of calcium silicate synthetic slurry, and stir Uniform, molded and dried above 100°C.

[0020] In this example, the total weight is 692g in terms of dry weight, and the iron oxide powder accounts for 12% of the total weight; in the calcium silicate insulation board intermediate, 100 parts of calcium silicate synthetic slurry, 2 parts of glass fiber, and 3 parts of pulp.

Embodiment 2

[0022] 242 g of iron oxide powder with a median diameter of 15 μm and 22.4 g of glass fiber were added to 5271 g (dry weight 448 g) of calcium silicate synthetic slurry, stirred evenly, molded, and dried above 100 °C.

[0023] In this example, based on dry weight, the total weight is 712.4g, and iron oxide powder accounts for about 34% of the total weight; in the intermediate of calcium silicate insulation board, 100 parts of calcium silicate synthetic slurry, 5 parts of glass fiber, and 0 parts of pulp share.

Embodiment 3

[0025] Add 460 g of aluminum silicate fiber cotton to 30 times of water and stir to make a slurry, then add 172 g of 325 mesh (median diameter about 47 μm) iron oxide powder, 9.2 g of polyacrylamide, 153 g of liquid silica sol (dry weight 46 g), stirring evenly to form a slurry, molding, and drying above 100°C.

[0026] In this example, the total weight is 687.2g in terms of dry weight, and the iron oxide powder accounts for about 25% of the total weight; in the aluminum silicate fiber board intermediate, 100 parts of aluminum silicate fiber cotton, 2 parts of polyacrylamide, and 10 parts of silica sol share.

Abstract

The invention discloses a preparation method of an efficient heat-insulating material. The efficient heat-insulating material comprises a substrate material and iron oxide powder, wherein the weight of the iron oxide powder is 12-34% of the dry basis total weight of all the materials; the substrate material is a calcium silicate heat-insulating plate intermediate body, an anorthite intermediate body or an aluminium silicate fiber plate intermediate body. An experimental result shows that compared with the same type of heat-insulating material not added with the iron oxide powder, the efficient heat-insulating material provided by the invention has the advantages that the heat conduction coefficient is obviously reduced, and the heat preservation and energy conservation effects of the heat-insulating material are remarkably improved.

Description

technical field [0001] The invention relates to a high-efficiency thermal insulation material, which belongs to the field of thermal insulation and energy-saving materials. technical background [0002] Due to its excellent thermal insulation properties, thermal insulation materials have been widely used in high-temperature thermal insulation industries such as building materials, metallurgy, electric power, and chemical industry in recent years. With the development of society and economy, energy conservation and emission reduction has increasingly become a social consensus. Industrial kilns and other fields have put forward higher requirements for the thermal insulation performance of thermal insulation materials. The existing common thermal insulation materials have been difficult to meet the requirements of industrial kilns. Therefore, the preparation of thermal insulation materials with low thermal conductivity is an important development direction of thermal insulatio...
