Abstract

The invention discloses a preparation method of a light-weight wall brick. The preparation method comprises the following three steps of: mixing, forming and solidifying; the wall brick is prepared from the following raw materials in parts by weight: 100 parts of cement, 20-25 parts of composite fillers, 3-5 parts of phosphate, 8-10 parts of reinforcing fibers, 0.8-1 part of expandable hollow polymer microspheres and 50-55 parts of water. The preparation method disclosed by the invention is simple, easy to operate and low in energy consumption; the light-weight wall brick prepared through the method has the advantages of low density, excellent mechanical property and sound insulation, heat insulation and flame retardant effect and is suitable for the preparation of a non-bearing wall in the field of buildings.

Description

technical field [0001] The invention belongs to the technical field of building filling materials, and in particular relates to a preparation method of lightweight wall bricks. Background technique [0002] A complete house has, in addition to load-bearing walls and beam structures, non-load-bearing walls for separation. The non-load-bearing wall itself is relatively light, in addition to having a certain strength, it also needs to have excellent sound insulation and heat insulation functions, and it also needs to have flame retardant properties. [0003] In order to obtain lightweight walls, porous building materials are generally used at present, mainly foamed concrete and foamed bricks. Foamed concrete materials have high cost, low strength, cracking, large shrinkage rate, and high water absorption rate; the existing foamed bricks are also made by adding foamed materials, which have the problems of complicated preparation and poor foaming uniformity, which lead The mech...
