Lightweight composite solid wallboard and manufacturing method thereof

Abstract

The invention belongs to the field of building material technology, and especially relates to a lightweight composite solid wallboard and a manufacturing method thereof. The invention aims at overcoming deficiencies in the prior art, and provides the lightweight composite solid wallboard which has the advantages of lightweight, saved energy and resources, shock prevention, flame retardation and heat insulation as well as the manufacturing method thereof. The invention provides a technical scheme as follows: the lightweight composite solid wallboard is characterized in that the wallboard is composed of a first main body and a second main body whose lateral parts are connected together, wherein the first main body and the second main body are separately comprise concrete material sandwich layers which are positioned in the bodies and surface board layers which are pasted on the double sides of the concrete material sandwich layers, and the surface board layers are fiber cement board layers. The invention also provides a method for manufacturing the lightweight composite solid wallboard, and a technical scheme comprises the following steps: (1) aluminium dies are cleaned; (2) liquid for demoulding is sprayed; (3) calcium silicate boards are installed in the aluminium dies; (4) tensioning leading screws are fastened; (5) EPS particles are foamed; (6) stirring materials are added into the assembled dies; (7) moulding speed is accelerated; (8) a die vehicle is transferred to the next process; (9) the leading screw of the die vehicle which reaches the time is loosened; (10) demoulding is carried out; (12) warehousing is carried out.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a lightweight composite solid wallboard and a manufacturing method thereof. Background technique [0002] With the rapid development of urban buildings and the continuous improvement of building functions, people have higher and higher requirements for environmental protection and energy saving of wall materials. The traditional wall materials are mainly solid clay bricks, which are often called "red bricks". "Brick", because the production of solid clay bricks needs to dig the ground, so it has caused great damage to the land, especially the cultivated land. The firing process requires a lot of energy, and releases a lot of carbon dioxide and sulfur dioxide, making the atmosphere Pollution and damage to the ecological environment, this product is not only heavy, but also requires a lot of labor and takes up a lot of space. According to statistics, the cur...

Problems solved by technology

[0003] At present, the sandwich layer of wall materials of similar products is mostly hollow or with a layer of benzene board in the middle. Although this type of product has many advantages, cracks, peeling and gaps are prone to occur in the bonding joints between the sandwich layer and the panel, resulting in wall panels. Low stability and short service life
