Fruit shell-type heat-insulating lightweight aggregate and preparation method thereof

Abstract

The invention discloses a fruit shell-type heat-insulating lightweight aggregate and a preparation method thereof. The fruit shell-type heat-insulating lightweight aggregate comprises an aggregate material, a shell material and a liquid material in a mass ratio of 1: (5-8): (3-5), wherein the aggregate material is polyphenyl particles or graphite-modified polyphenyl particles; the shell material comprises fireproof powder, floating beads and cement in a mass ratio of 1: (0.5-2): (4-6); and the liquid material comprises a hydrophilic modifier, a butylbenzene polymer emulsion and water in a mass ratio of 1: (15-25): (15-25). The fruit shell-type heat-insulating lightweight aggregate and the preparation method thereof belongs to the technical field of heat-insulating energy-saving materials for buildings; and specifically, the heat-insulating particles, i.e., lightweight aggregate, in the heat-insulating material to compounding, wrapping and enclosing so as to improve strength, enhance adhesion stress, reduce heat conduction coefficient, improve fireproof performance and lower water absorption rate.

Description

technical field [0001] The invention belongs to the technical field of building thermal insulation and energy-saving materials, and specifically refers to a shell-type thermal insulation lightweight aggregate and a preparation method thereof. Background technique [0002] With the rapid development of industry and economic development, the world's demand for energy is also increasing. In the increasing total energy consumption, building energy consumption is particularly large, accounting for about 11-25% of the total energy consumption. %, a large number of data and experiments have shown that the fastest and most effective way is to use thermal insulation and energy-saving materials. At present, in my country's building insulation market, polystyrene particle insulation mortar, polystyrene particle insulation board, polymer insulation board and inorganic insulation mortar, inorganic insulation board, expanded perlite insulation board, etc. have been widely used as building...
