Abstract

The invention belongs to the field of construction materials and specifically relates to a method for preparing a flexible veneer sheet from modified mineral powder. The method provided by the invention comprises the following steps: pulverizing and calcining minerals such as colored sand and quartz stone, and then spraying substances such as castor oil on the surface of the mineral powder to obtain a modifier; performing aging and rolling to obtain the modified mineral powder; and taking the modified mineral powder, redispersible latex powder and a fireproof emulsion as main raw materials toprepare the flexible veneer sheet. After the mineral powder is modified, the friction resistance and the fluidity of the mineral powder are improved, and the compatibility between the mineral powder and the emulsion as well as the redispersible latex powder also can be improved; and after the modified mineral powder is added into the flexible veneer sheet, the rupture strength and the friction resistance of the flexible veneer sheet can be improved, so that the method provided by the invention has wide application prospects.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a method for preparing a flexible decorative sheet with modified mineral powder. Background technique [0002] Flexible facing sheet (i.e. flexible facing brick) is a new type of interior and exterior wall decorative surface material made of inorganic materials as the main base material and polymer redispersible emulsion powder after special processing. It has certain flexibility, Ceramic texture, energy-saving and environment-friendly new decorative material for facings, has the advantages of rich color, thin thickness, light weight, good durability, and convenient construction. High-rise building exterior wall decoration and interior decoration. Because its color, structure and shape can be specially formulated according to the requirements of users, and the construction is simple and durable, especially its appearance and surface shape are very similar to traditi...
