Decorative high-performance wallboard based on formwork back marking process and preparation method thereof

Abstract

The invention discloses a decorative high-performance wallboard based on a formwork back marking process, and the decorative high-performance wallboard is characterized in that the decorative high-performance wallboard comprises a decorative board and a large-cavity wallboard, wherein the hollow rate of the large-cavity wallboard is greater than and equal to 65% and prepared by fiber-reinforced cement-based composite materials through a grouting extrusion process. The invention further discloses a preparation method for the decorative high-performance wallboard based on the formwork back marking process. The decorative board of the decorative high-performance wallboard is quickly fixed on the side of a mold through electromagnetic force, so the problem of fixing the decorative board quickly when a formwork mold uses the back marking process; and the problems of sliding, incomplete spicing and slurry dripping of the decorative board when the fiber-reinforced cement-based composite material is grouted and extruded are effectively solved, and meanwhile, the large cavity wallboard adopts the grouting extrusion process to improve the bonding strength of the decorative board and the large cavity wallboard effectively.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a decorative high-performance wallboard based on a vertical formwork reverse technology and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the requirements for the performance and decorative effect of buildings are also getting higher and higher. There are more and more high-performance cement-based materials in the field of building materials, but most of the high-performance cement-based materials still use the traditional cast-in-place process, which cannot give full play to the advantages of high-performance cement-based materials. Quality issues still exist, affecting the compactness, mechanical properties and long-term durability of cement substrates. In addition, cast-in-place concrete wall panels and prefabricated wall panels have the problem of being heavy, and the adhesion to the decorative pan...

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly overcomes the deficiencies in the prior art. Aiming at this, the present invention provides a decorative high-performance wallboard based on the vertical formwork reverse technology, which is characterized in that the decorative high-performance wallboard is made of Composed of decorative panels and large cavity wall panels, the large cavity wall panels are made of fiber reinforced cement-based composite materials through grouting extrusion molding, and the decorative panels are fixed by the electromagnetic force between the electromagnet and the metal sheet, forming a reaction during grouting extrusion. The decorative high-performance wallboard prepared by this method has high strength, compact structure, good durability and its own decorative effect. It successfully solves the problems of slippage and uneven splicing of large-cavity wallboards. At the same time, the bonding strength, safety and durability of the decorative panel and the large cavity wallboard are effectively improved, and the problems of easy falling off of the decorative panel, heavy weight of the wallboard and poor durability are solved.
