At present, the base treatment link often relies on manual leveling, which has low precision and is prone to cause large errors in the flatness of the base surface, thereby causing the wallboards installed subsequently to warp, hollow, etc. At the same time, incomplete cleaning of the base surface will seriously affect the bonding strength of the wallboard and the base due to the residual dust, oil stains, etc.

[0003] In terms of the use of interface agents, traditional interface agents are mostly single components, which have limited bonding performance with the base and the wallboard, poor water resistance and weather resistance, and are prone to interface layer peeling after long-term use, resulting in wallboard loosening. In addition, the preparation process of traditional interface agents is simple, and the raw material ratio is unreasonable, which further limits the performance of the interface agents. During the pretreatment of decorative wallboards, insufficient cutting accuracy will cause large gaps at the splicing positions of the wallboards, affecting the decoration effect, and the use of wallboards with defects will reduce the stability of the overall installation structure. During the installation of wallboards, the bonding materials used have uneven performance, and the application method is not standardized, resulting in insufficient bonding strength and easy displacement and peeling of the wallboards.
