Portland cement foamed lightweight partition board and preparation method thereof

Abstract

The invention provides a Portland cement foamed lightweight partition board. The invention is characterized in that 10 Portland cement foamed lightweight partition boards (length*width*height is 2900mm*600mm*90mm) are prepared from the following raw materials by weight: 200-260kg of water, 500-550kg of 425 Portland cement, 30-50kg of calcium carbonate, 30-50kg of calcium oxide, 4-6kg of a water-proof flexibilizer, 2-5kg of a quick setting reinforcing agent, 10kg of 30-60mm anti-crack fibers and a proper amount of foam. The invention further provides a preparation method of the Portland cement foamed lightweight partition board. The Portland cement foamed lightweight partition board has the advantages of energy conservation, environment friendliness, high strength, no deformation, long service life, good heat insulating, damp-proof and fire-proof effects. The preparation method is scientific and reasonable and is low in cost and high in efficiency.

Description

technical field [0001] The invention relates to the field of building materials, and relates to a Portland cement foamed lightweight partition wall board and a manufacturing method thereof. Background technique [0002] Existing gypsum foam boards have poor durability; magnesite cement foamed lightweight partition boards have high production costs, are prone to anti-halogen and anti-alkali, warping and deformation, peeling off, and short service life; sulphoaluminate cement foaming Lightweight partition wall panels have poor compressive strength, are easy to fall off, have high surface density, and high production costs; cement-polystyrene particle-mixed partition wall panels have high surface density, high production costs, and are prone to cracking and delamination when used in areas with large temperature differences. Contents of the invention [0003] The purpose of the present invention is to substantially improve and innovate the existing technology, to provide an en...
