Abstract

The invention discloses a green energy-saving heat preservation material and a preparing method thereof. The preparing method includes the following steps that 1, the temperature in a reaction tank is adjusted to 80 DEG C-110 DEG C, 12-18 parts of kieselguhr, 7-15 parts of alumina silicate fibers, 2-6 parts of flyash, 5-10 parts of magnesium carbonate, 4-9 parts of sepiolite fibers, 2-6 parts of hydrogenated acrylonitrile butadiene rubber are added, and the components in the reaction tank are stirred evenly; 2, 6-12 parts of brominated maleic rosin epoxy resin, 4-10 parts of copal, 6-14 parts of polyacrylate emulsion and 2-6 parts of bagasse cellulose xanthate are added and stirred; 3, the mixed material obtained in the step 2 is transferred into a pressing mold, and the mold is pressurized to prepare the green energy-saving environment-friendly material. The heat preservation performance, fracture resistance and water resistance of the green energy-saving heat preservation material are improved, and the green energy-saving heat preservation material can be used for heat preservation of buildings, building materials and mechanical equipment.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, and in particular relates to a green energy-saving thermal insulation material and a preparation method thereof. Background technique [0002] Common thermal insulation materials, inorganic materials include expanded perlite, aerated concrete, rock wool, glass wool, etc., organic materials include polystyrene foam, polyurethane foam, etc. The thermal insulation performance of these materials is mainly determined by the thermal conductivity of the material (the index is thermal conductivity). The more difficult the heat conduction of the material (that is, the smaller the thermal conductivity), the better its thermal insulation performance. Generally speaking, the common feature of thermal insulation materials is that they are light, loose, porous or fibrous, and use the air that does not flow inside to block heat conduction. Among them, inorganic materials have the characteristics of...
