Problems solved by technology

Existing exterior walls of concrete frame structures are generally composed of independent main structures and insulation layers to meet the various functional requirements of building exterior walls. It is difficult to unify the properties such as thermal conductivity, and when affected by external environmental factors, the combination between the thermal insulation material and the main structural material is also easily affected, thereby shortening the service life of the building's exterior wall

Abstract

The invention provides a lightweight ceramic self-insulation wallboard and a preparation method and application thereof. The self-insulation wallboard comprises a heat preservation layer and a decoration layer. The heat preservation layer comprises blast furnace slag, steel slag, solid waste, a foaming agent, a fluxing agent, a foam stabilizer and a component regulator, and the decorative layer comprises blast furnace slag powder, waste ceramic powder, waste glass powder, steel slag powder and a component regulator; the decoration layer and the heat preservation layer are sintered together, and then 3D printing of a pre-selected decoration pattern is carried out after polishing. The raw materials of the lightweight ceramic self-insulation wallboard adopt the blast furnace slag, the steel slag, the solid waste and other substances, and the lightweight ceramic self-insulation wallboard has the characteristics of simple preparation method, energy conservation, waste utilization, high added value, economy and reasonability, so that the lightweight ceramic self-insulation wallboard has the characteristics of good mechanical property, low water absorption, good veneer ultraviolet aging resistance and the like; the wallboard is mainly applied to the field of self-thermal-insulation of building walls, and can also be used for heat insulation and waterproof layers of external wall heat-insulation decorative integrated plates, assembly type partition walls and roofs.

Description
