Wall material and preparation method thereof

Abstract

The invention provides a wall material and a preparation method thereof and relates to the field of building materials. The wall material is prepared from raw materials in parts by weight as follows: ceramic polishing residues, feldspar, calcined talc, red mud, dickite, barium carbonate, silicon carbide, waste polystyrene boards, ceramic fiber, sepiolite, expanded glass beads, phenolic foam, glass wool, nano calcium carbonate powder, boron carbide, a binder and water. The preparation method comprises the steps as follows: (1) raw material weighing; (2) crushing; (3) wet ball milling; (4) screening and drying; (5) placement in a kiln; (6) sintering; (7) cutting. The problems that existing wall building materials have defects in fireproof performance, thermal insulation performance and compressive strength and cannot meet the comprehensive performance requirement of high-standard buildings for the wall materials are solved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a wall material and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of people's living standards, people have higher and higher requirements for building materials, especially wall materials in building materials. However, in the existing wall materials, there are low compressive strength, Poor fire resistance and general thermal insulation effect. [0003] In the Chinese patent document published on February 17, 2016, a wall building material and its preparation method (authorized announcement number CN103896619B), the wall building material includes the following raw materials in parts by weight: 50-80 parts of ceramic polishing slag, 0-30 parts of feldspar, 2-10 parts of calcined talc, 10-20 parts of red mud, 0-10 parts of lithium feldspar, 0-15 parts of dikaiite, 0.5-2 parts of silicon carbide, 1.5-3 p...
