Abstract

The invention discloses an energy-saving heat insulation material prepared from waste tea leaf residues and a preparation method of the material. The energy-saving heat insulation material comprises,by weight, 15-23 parts of cement, 30-42 parts of waste tea leaf residues, 12-17 parts of itaconic acid, 7-10 parts of sodium polystyrene sulfonate, 8-12 parts of ethylene diamine tetra(methylene phosphonic acid) sodium, 14-18 parts of polysilicic acid aluminum ferrous chloride and 85-150 parts of water. The energy-saving heat insulation material has the advantages of good heat insulation effect, good escherichia coli resisting effect, good staphylococcus aureus resisting effect, excellent flame resistance, high mechanical strength, high water resistance and the like. By optimizing a preparation process, product quality can be effectively improved, and the energy-saving heat insulation material has good economic and social values.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to an energy-saving thermal insulation material prepared by using waste tea leaves 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. However, conventional energy-saving thermal insulatio...
