Abstract

The invention relates to the technical field of building materials, and particularly provides a composite material and a preparation method, a modification method and application thereof. The preparation method of the composite material comprises the steps that liquid metal and/or metal alloy are/is adopted to soak the lightweight aggregate, filtering is conducted, filter residues are collected, and the composite material is obtained. The composite material prepared through the method can form an effective air diaphragm, the sound barrier effect is greatly enhanced, metal tin coagulated on the surface of the material is in irregular orientation, the heat conduction efficiency in all directions can be greatly improved, and good heat conduction and sound insulation effects are achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composite material and its preparation method, modification method and application. Background technique [0002] Floor heating is the abbreviation of floor radiant heating. It uses the whole ground as a radiator, heats the whole ground evenly through the heat medium in the radiant layer of the floor, and supplies heat to the room through the heat transfer mode of radiation and convection through the ground to achieve the purpose of comfortable heating. [0003] The structure and characteristics of each layer of traditional floor heating from bottom to top are: [0004] (1) Structural layer: reinforced concrete floor; [0005] (2) Thermal insulation reflective layer: used to insulate heat transfer downward; apply reflective film on top to prevent downward radiation heat transfer; [0006] (3) Steel mesh: radiate heat evenly to avoid failure caused by excessive loca...
