Wood fiber composite wallboard for prefabricated building and preparation method thereof

Abstract

The embodiment of the invention discloses a wood fiber composite wallboard for prefabricated buildings and a preparation method thereof. The composite wallboard includes an inner ply, an interlayer, an outer ply, and a support frame; the contact surface between the interlayer and the inner ply It is formed as a plane, and the contact surface between the interlayer and the outer plate is formed as a wave surface, and a plurality of water-absorbing bumps protrude from the interlayer; the interlayer contains at least wood fiber material. The preparation method includes placing the support frame in a mold; pouring concrete into the mold; pressing the outer panel embryo with a pressing plate, and then placing the steam pre-curing at a temperature of 40-50°C for 0.5-1h; The surface of the body is poured with materials for preparing the interlayer and then molded; the surface of the interlayer is poured with concrete until it is preliminarily formed in the mold, and then the concrete is cured to obtain the wood fiber composite wallboard for the prefabricated building. The effect of anti-seepage and good temperature difference resistance has been realized.

Description

technical field [0001] The embodiment of the present invention relates to the field of wallboards for prefabricated buildings, in particular to a wood fiber composite wallboard for prefabricated buildings and a preparation method thereof. Background technique [0002] Prefabricated building refers to the type of building that is formed after the production and processing of building components and accessories, and then transported to the construction site for direct installation of components. Since it does not need to be produced on the construction site, it can realize large-scale production in factories, which not only greatly reduces the generation of construction waste, but also effectively improves the construction efficiency of buildings. [0003] In the prior art, components such as wall panels in prefabricated buildings are mainly PC components (ie prefabricated concrete components). When they are used as wall panels, they need to be assembled because they are prefa...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, components such as wall panels in prefabricated buildings are mainly PC components (ie prefabricated concrete components). When they are used as wall panels, they need to be assembled because they are prefabricated panels. Therefore, in the later stage It is easy to cause some problems such as leakage due to difficult or poor treatment of the seam, which leads to certain defects in its waterproof performance, and the difference in temperature will further increase its defects in waterproof performance
