Light heat-preservation type outer wall building board

Abstract

The invention provides a light heat-preservation type outer wall building board. The light heat-preservation type outer wall building board comprises a heat-preservation layer, a cement-based protective layer, bonding layers and a heat-preservation transition layer, wherein the bonding layers are arranged on the two sides of the heat-preservation layer; a plurality of stopping convex ribs protruding towards the heat-preservation layer are arranged on the bonding layers; the stopping convex ribs arranged on the bonding layers on the two sides of the heat-preservation layer are distributed in astaggered mode in the height direction of the light heat-preservation outer wall building board; the heat-preservation layer is filled with rock wool and an XPS extruded sheet; the rock wool and the XPS extruded sheet are arranged at intervals through partition plates; the rock wool is limited and stopped in the height direction through the stopping convex ribs arranged in the staggered mode in the height direction; the rock wool and the XPS extruded sheet are arranged in the heat-preservation layer, so that the heat-preservation and fireproof performance of the building board can be improved;the XPS extruded sheet can improve the supporting performance of the heat-preservation layer of the building board in the horizontal direction; and the arranged partition plates can ensure that two heat-preservation cavities are independent of each other, and the two materials are prevented from moving in the heat-preservation layer.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a lightweight thermal insulation exterior wall building board. Background technique [0002] During the construction of the exterior wall of the building, a layer of insulation board needs to be attached to realize the thermal insulation and cold insulation effect of the exterior wall, and ensure the performance of the exterior wall of the building and the indoor temperature of the building. The existing thermal insulation building panels are usually equipped with rock wool, which realizes heat preservation and fire prevention. If the rock wool is not fixed well inside the building panels of the outer wall, the installation position inside the building changes, which will seriously affect the performance of the building panels. Insulation and fire performance. Moreover, rock wool material has good fire resistance performance, but rock wool material is a flexible materi...

AI Technical Summary

Problems solved by technology

The existing thermal insulation building panels are usually equipped with rock wool, which realizes heat preservation and fire prevention. If the rock wool is not fixed well inside the building panels of the outer wall, the installation position inside the building changes, which will seriously affect the performance of the building panels. Insulation and fire resistance performance, moreover, rock wool material has good fire resistance performance, but rock wool material is a flexible material, and the filling and setting in the building board has poor support performance for the building board in the horizontal direction, which affects the overall strength of the building board
