Problems solved by technology

However, the exterior wall decorative panels are not perfect. Based on the durability and weather resistance requirements of the building's exterior wall protection and decoration and the application in different regional environments, there are currently many expansion and contraction deformations after water absorption, large deformation rates after freeze-thaw cycles, There is a risk of warping. In recent years, in practical applications, insufficient adhesion strength of the finish coating and delamination and peeling of the coating after freeze-thaw cycles have sometimes occurred.
In addition, based on the high weather resistance requirements of exterior wall finishes, most of the exterior wall decoration panels are currently finished with fluorocarbon coatings, which not only imitate the smooth finish of aluminum plates, but also have relatively single finish effects, especially difficult to meet People are particularly fond of the effect of exterior wall stone (granite, marble, etc.)
In addition, with the increasing number of high-rise buildings in my country's cities in recent years, the full implementation of external wall insulation systems and the implementation of national resource protection policies, natural stone is also due to its heavy texture, high cost, difficult processing, complex installation process, and installation. The application is limited by factors such as difficulty and natural radiation, but the decorative effect of natural stone is still favored and desired by builders.

Abstract

The invention provides an outer wall stone-simulated decorative plate and a manufacturing method of the outer wall stone-simulated decorative plate. The defects that a regular outer wall decorative plate is single in decoration effect, large in water absorbing rate, prone to expansion by being wet, deforming and tilting and insufficient in stability of anti-freezing-and-thawing cycle are overcome. The outer wall stone-simulated decorative plate is low in water absorption and resistant to freezing and thawing. In addition, the technologic manner which includes optimizing a base plate, sanding and polishing the base plate, enhancing the waterproof performance, coating interface undercoat, coating stone-simulated paint, drying by roasting, protection coating of a hood face and drying by roasting is ascertained. The decorative face of the outer wall stone-simulated decorative plate can simulate the outer effect of a granite stone material with high fidelity and the outstanding features of light weight, high strength, low water absorption, resistance to the freezing and thawing cycle, high weather resistance and durability are achieved. The defects of a traditional outer wall decorative plate are overcome and the requirement for effectiveness of application of a building outer wall can be better met.

Description

technical field [0001] The invention relates to an exterior wall decorative board, in particular to a low water absorption, freeze-thaw resistant exterior stone imitation decorative board and a manufacturing method thereof, belonging to the technical field of building decoration materials. Background technique [0002] As a new material for building exterior wall decoration and protection, exterior wall decorative panels have been favored by the market for their excellent performances such as "light weight, high strength, stability and weather resistance, waterproof and durable, low-carbon energy saving, convenient installation, efficient construction, and neat finishes". There are more and more applications in building exterior wall decoration. However, the exterior wall decorative panels are not perfect. Based on the durability and weather resistance requirements of the building's exterior wall protection and decoration and the application in different geographical environ...
