Method for preparing high-performance composite wallboard by using waste construction waste or industrial waste residue

Abstract

The invention relates to a method for preparing a high-performance composite wallboard by using waste construction wastes or industrial waste residues, the composite wallboard is composed of hard layers with holes, a middle sandwich heat insulation layer and a reinforcing steel reinforcement cage, the upper and lower mesh surfaces of the reinforcing steel reinforcement cage are respectively embedded in the middle of the hard layers with the holes; comprising the following steps: step 1, preparing a base material of a hard layer with holes; step 2, assembling a mold; thirdly, a plastic core-pulling pipe is inserted, and the plastic core-pulling pipe is inserted into the mold along the hole of the plug on one side of the mold and comes out of the other end of the plug with the hollow part; and 4, pouring a hard layer base material with holes, and solidifying and demolding to form the product. According to the invention, the existing construction waste or industrial waste residue is used as the raw material to manufacture and produce the composite wallboard, so that a large amount of waste construction waste or industrial waste residue can be reasonably utilized, waste is turned into wealth, the production cost of the composite wallboard can be greatly reduced, and a good environment-friendly effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a method for preparing high-performance composite wall panels by using waste construction waste or industrial waste residue. Background technique [0002] Composite wallboard is a new generation of high-performance building interior partition produced in industrialized production. It is made of various building materials and replaces traditional bricks and tiles. , The obvious advantage of fast construction. [0003] Composite wallboards usually use ordinary portland cement, sand and fly ash or other industrial wastes such as water slag, slag, etc. The special mixing system for forced light aggregates introduces air during the mixing process to form honeycomb-shaped stable pores in the core layer to further reduce the product's bulk density, which not only reduces material costs, but also achieves ideal heat preservation and sound insulation effects.

Problems solved by technology

[0006] Although concrete-based composite wall panels have the effect of avoiding sound insulation and temperature difference and low cost, however, a large amount of additional concrete is required for pouring, which is not practical today when concrete resources are tight.
