Abstract

The invention relates to building materials, the invention particularly discloses a light thermal insulation material. The light thermal insulation material is prepared from the following components in parts by mass: 25 to 40 parts of cement, 5 to 15 parts of superfine slag powder, 1 to 5 parts of polyphenyl granules, 10 to 25 parts of metakaolin, 1 to 10 parts of fiber, 5 to 15 parts of tile slate tailings and 5 to 10 parts of an alkaline excitant. The preparation method of the light thermal insulation material comprises the following steps: 1, preparing materials, namely sieving tile slate tailings and the superfine slag powder to enable the tile slate tailings and the superfine slag powder to meet the particle size requirement; adopting hemp ropes, and preparing hemp rope fine fibers from the hemp ropes through shearing; 2, carrying out dry mixing on cement, superfine slag powder, polyphenyl granules, metakaolin, fibers, tile slate tailings and the alkaline excitant to obtain a mixture. The light thermal insulation material is light in weight, high in strength and suitable for popularization.
