Abstract

The invention discloses a novel heat-isolation, heat-insulation and energy-saving material and a preparation method thereof. The novel heat-isolation, heat-insulation and energy-saving material is prepared from the following raw materials in parts by weight: 22 to 48 parts of slate, 15 to 21 parts of building gypsum, 3 to 6 parts of converter ore slag, 12 to 15 parts of waste rock wool, 22 to 30 parts of floating bead, 11 to 15 parts of sepiolite, 4 to 10 parts of volcanic ash, 4 to 9 parts of hollow inorganic fiber, 10 to 13 parts of modified starch, and 2 to 7 parts of liquefied resin. The novel heat-isolation, heat-insulation and energy-saving material has the advantages that by using the building gypsum, the converter ore slag and the waste rock wool as the main materials, the cost isreduced; by assisting with the slate, the floating bead, the sepiolite and the volcanic ash, the strength and heat insulation property are improved; by adding the hollow inorganic fiber, the fiber layer can be formed, so that the heat insulation property and toughness are improved; by adding the liquefied resin and the modified starch, the components in the material can be firmly bonded together,so that the strength is higher.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to a novel thermal insulation and energy-saving material and a preparation method thereof. Background technique [0002] Insulation materials are generally materials with a thermal coefficient less than or equal to 0.2. The development of thermal insulation materials is rapid, and the use of good thermal insulation technology and materials in industry and construction can often achieve twice the result with half the effort. Although organic thermal insulation materials are widely used in the market at present, although they have low thermal conductivity, their strength is low and they are not waterproof enough. Inorganic thermal insulation materials with cement as the binder have high thermal conductivity and high strength, but the energy-saving effect is not good. However, some insulation materials made of inorganic materials have complicated manu...
