Abstract

The invention provides a waterproof isolation plate. The waterproof isolation plate uses industrial solid waste alkaline residues as a main raw material and achieves the purposes of excellent waterproof performance and high strength through the cooperation of the alkaline residues, an aggregate forming agent, lime and cellulose. The aggregate forming agent provided by the invention has a gelling property, and in the process of hardening, the strength of the alkaline residues is excited, and the strength of the obtained isolation plate is improved; the lime can improve the tensile strength of the alkaline residues and the aggregate forming agent, and can also react with a part of raw aluminum oxide or silicon oxide in the aggregate forming agent to generate substances with hydraulic performance so as to realize cementation, so the strength of the isolation plate is further improved; and the cellulose can improve the toughness and strength of the isolation plate. According to the waterproof isolation plate provided by the invention, through the interaction of all the components, the obtained waterproof isolation plate has good impact resistance, bending resistance, small drying shrinkage rate and good waterproof performance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a waterproof isolation board and a preparation method thereof. Background technique [0002] Partition wall panels are prefabricated slats for walls used in non-load-bearing parts of buildings. Commonly used partition boards in the prior art include glass fiber reinforced cement strips, glass fiber reinforced lime hollow strips, pressurized aerated concrete strips, steel wire reinforced cement strips, light concrete strips, and composite sandwich lightweight Batten and more. Glass fiber reinforced cement lightweight porous partition wall panels are referred to as GRC lightweight partition wall panels. The hollow slats are made of glass fiber roving and its mesh cloth as reinforcing materials, light inorganic composite materials such as perlite and ceramsite as light aggregates, and external admixtures such as fly ash and slag. It has the characteristics ...
