A kind of fiber-reinforced cement-based foam insulation board manufacturing process

Abstract

The invention discloses a technical method for manufacturing a fiber reinforced cement based foam insulation board. The method comprises the following step: charging, namely, placing a prefabricated cement based foam insulation base board which is cut to reach thickness as requirement on a conveying platform of a flow production line; forwards conveying along with the conveying platform, wherein the surface of the base board is sequentially treated by dedusting, mortar spreading, mesh spreading and pressing, mortar coating and scraping, and synchronous cutting when the base board on the conveying platform is forwards conveyed. The method is characterized in that the mortar is directly input to the surface of the base board through a discharging control device during mortar spreading, and the mesh is pressed into the mortar spread on the surface of the base board; then a scraping plate which is transversely arranged along the conveying platform is operated to automatically scrape and level the passing mortar. According to the method, the mesh of the cement based foam insulation board can be combined and spread; in addition, the method has the advantages of being simple and quick tospread the mortar, reliable, high in spreading quality, thin and full in a mortar layer, simple in processes, high in efficiency, and high in product quality.

Description

technical field [0001] The invention belongs to the technical field of production of building thermal insulation materials, and in particular relates to a manufacturing process for a fiber-reinforced cement-based foam thermal insulation board. Background technique [0002] The fiber-reinforced modified foamed cement-based foam insulation board includes the insulation board substrate and the fiber reinforced layer arranged on the surface of the insulation board substrate. The insulation board substrate is made of cement foam board, that is, a foaming agent is added to the cement to make the interior The formation of fine pores, which has the function of heat preservation. However, the strength of the cement foam board is low, so in order to improve the strength, on the basis of the cement foam board, the fiber-reinforced modified foamed cement-based foam insulation board is obtained by compounding the grid cloth on its surface, which can greatly improve the strength of the ce...

Problems solved by technology

[0006] The second is to use the method of soaking to realize the laying of slurry. The process is more complicated, and the slurry is easy to fall, and the cement board does not need to lay the mesh cloth on the surrounding sides and will also be soaked and scraped, resulting in waste and reduced efficiency.
