Abstract

The invention discloses an anti-cracking calcium silicate board and a preparation process thereof. The anti-cracking calcium silicate board is prepared from the following raw materials in parts by weight: 30-40 parts of alkaline residues, 4-8 parts of slaked lime, 12-16 parts of cement, 20-24 parts of quartz powder, 1-2 parts of yttria-stabilized zirconia, 0.3-0.7 part of sodium polyacrylate, 3-6 parts of beta eucryptite glass fibers, 5-7 parts of paper pulp and 1-3 parts of anhydrous sodium sulfate. According to the calcium silicate board, the beta eucryptite glass fibers and the paper pulp fibers are adopted as fiber raw materials to jointly replace traditional asbestos fibers, the calcium silicate board is non-toxic and more friendly to human bodies and the environment, meanwhile, crack propagation can be well stopped, the propagation direction can be well changed, the propagation path can be well increased, and the anti-cracking effect of the calcium silicate board is achieved.

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,...
