Problems solved by technology

[0002] The existing commonly used formwork for building exterior wall insulation is FS composite thermal insulation external formwork. The structure of FS composite thermal insulation external formwork is divided into three layers. The middle layer is XPS insulation layer, the lower layer is thin bonding mortar, and the upper layer is two layers of bonding mortar. A layer of thermal insulation mortar is sandwiched; however, during use, hollowing often occurs between the XPS thermal insulation layer and the upper and lower layers of mortar. Once external forces occur, such as strong winds, the XPS thermal insulation layer and bonding mortar are easy to peel off, causing damage to the building. People and objects under the objects pose a great safety hazard

Abstract

The invention relates to the field of building thermal insulation materials and particularly relates to an external building wall thermal insulation board and a preparation method thereof. The preparation method of the external building wall thermal insulation board comprises forming sawtooth grooves in bilateral sides of an extruded plate; paving adhesive mortar on one side of the extruded plate and embedding the adhesive mortar into the sawtooth grooves to increase the binding force between the extruded plate and the adhesive mortar; conserving until the adhesive mortar is completely harden; sequentially paving thermal insulation mortar and adhesive mortar on the other side of the extruded plate, enabling the thermal insulation mortar and the extruded plate to be directly in contact to enable the thermal insulation effect to be obvious, reducing energy consumption, saving production costs and improving the production efficiency and the product yield; conserving until the motor is complete harden to obtain the finished external building wall thermal insulation board. The external building wall thermal insulation board obtained from the preparation method has the advantages of being tight in interlayer connection, greatly reducing empty drums, being good in performance stability and having the service life as the building.
