Fabricated composite light heat preservation and sound insulation wallboard and manufacturing method thereof

Abstract

The invention discloses a fabricated composite light heat preservation and sound insulation wallboard and a manufacturing method thereof, relates to the technical field of wallboard manufacturing, and aims to solve problems of high manufacturing cost, heavy weight and poor sound insulation effect of wallboards in the prior art. The manufacturing method comprises the following steps that a plurality of long boards, short boards, top boards and bottom boards are manufactured, a plurality of long boards and a plurality of short boards are enclosed to form a frame, and the top board and the frame as well as the bottom board and the frame are connected through mortise and tenon joint structures to form a box body; after the box body is manufactured, expanded slurry is poured into the box body, the expanded slurry is subjected to an expanded reaction and then is fully bonded with the interior of the box body, the whole box body is filled with the expanded slurry, an internal heat-preservation and sound-insulation layer is formed, and the heat-preservation and sound-insulation wallboard is manufactured after reaction is completed and curing is conducted. The manufacturing method is advantaged in that expanded slurry is expanded to form a heat preservation and sound insulation layer, so the wallboard prepared from the phosphogypsum with lower cost is lower in cost, lighter in weight per unit volume and better in sound insulation effect.

Description

technical field [0001] The invention relates to the technical field of wallboard manufacture, and more specifically relates to the technical field of an assembled composite lightweight thermal insulation wallboard and a manufacturing method thereof. Background technique [0002] Wall panels are divided into two categories: interior wall panels and exterior wall panels. There are three types of interior wall panels: horizontal wall panels, vertical wall panels and partition wall panels. The horizontal wall panels and vertical wall panels are both load-bearing wall panels. For non-load-bearing wall panels, the inner wall panels should have the functions of sound insulation and fire prevention; the outer wall panels include front outer wall panels, gable panels and eave wall panels, and the front outer wall panels are self-supporting wall panels, gable wall panels and eave wall panels The panels are load-bearing wall panels, and the exterior wall panels should have the function...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the problems of high production cost, heavy quality and poor sound insulation effect of the wallboard itself in the prior art, the present invention provides an assembled composite lightweight thermal insulation and sound insulation wallboard and its manufacturing method , the frame, top plate and bottom plate are jointly made into a box body, and puffed slurry made of phosphogypsum is injected into the box body, and the puffed slurry is expanded to form a thermal insulation layer, so that phosphogypsum with lower cost can be used. Moreover, the cost of the wall panel is lower, the weight per unit volume is lighter, and the sound insulation effect is better.
