Abstract

The invention discloses an anti-cracking calcium silicate board and a preparation process thereof, which is prepared from the following raw materials in parts by weight: 30-40 parts of alkali slag, 4-8 parts of slaked lime, 12-16 parts of cement, and 20-24 parts of quartz powder , 1-2 parts of yttria-stabilized zirconia, 0.3-0.7 parts of sodium polyacrylate, 3-6 parts of β-eucryptite glass fiber, 5-7 parts of pulp, and 1-3 parts of anhydrous sodium sulfate. The calcium silicate board of the present invention uses β-eucryptite glass fiber and pulp fiber to replace the traditional asbestos fiber on the fiber raw material, which is non-toxic, more friendly to the human body and the environment, and can well prevent the crack from expanding and change the expansion. direction, increase the expansion path, and achieve the anti-cracking effect of the calcium silicate board.

Description

technical field [0001] The invention belongs to the technical field of calcium silicate boards, and in particular relates to an anti-cracking calcium silicate board and a preparation process thereof. Background technique [0002] Calcium silicate board is a new type of inorganic building decoration material. Because of its high strength, light weight, good processability and non-combustibility, it is widely used in ship bulkheads, suspended ceilings and non-load-bearing buildings. Walls, and other places with fire protection requirements. As a new green and environmentally friendly building material, in addition to the functions of traditional gypsum boards, it also has the advantages of superior fire resistance, moisture resistance, and long service life. It is widely used in suspended ceilings and partition walls of industrial and commercial engineering buildings, home decoration, and furniture linings. , billboard lining board, ship partition board, warehouse shed board,...
