The novel antibacterial thermal-insulation brick comprises, by weight, 10 to 20 parts of industrial coal slag, 8 to 17 parts ofbuilding garbage, 5 to 12 parts of waste circuit board, 15 to 25 parts of Portland cement, 7 to 13 parts of expanded perlite, 5 to 10 parts of nut shell, 6 to 14 parts of glass bead, 13 to 21 parts offly ash, 9 to 18 parts of bentonite, 12 to 19 parts of modified diatomite, 5 to 11 parts of wood chip, 4 to 8 parts of kaolin, 5 to 10 parts of borax, 6 to 12 parts of tourmalinite powder, 1 to 4 parts of lignocelluloses, 2 to 6 parts of polyvinyl alcohol fiber, 1 to 3 part of a water reducer, and 2 to 3 parts of a foaming agent. The novel antibacterial thermal-insulation brick possesses excellent thermal insulation properties, is light in weight, is high in compression strength, and possesses antibacterial performance, and air purification performance.

Description

technical field [0001] The invention belongs to the technical field of energy-saving materials, and in particular relates to a novel antibacterial thermal insulation brick and a preparation method thereof. Background technique [0002] In buildings, the heat loss of the outer envelope structure is relatively large, and the wall accounts for a large share in the outer envelope structure. Therefore, the reform of building walls and the development of wall energy-saving technology are the most important links in building energy-saving technology, and the development of external wall insulation technology and energy-saving materials is the main way to realize building energy conservation. [0003] The commonly used perlite insulation brick is a new type of building decoration material, which has the excellent characteristics of low thermal conductivity, stable performance, light weight, fire prevention, non-toxic and tasteless, and can be widely used in office buildings, hotels,...
