Abstract

The invention belongs to the field of building materials and provides a preparation method of flexible decorative bricks. The preparation method comprises the steps of 1) taking desert aeolian sand as a raw material, scrubbing, drying and then screening to obtain raw sand of 20-200 meshes; 2) laminating and coloring the raw sand to obtain color sand with different colors; 3) adding an adhesive, an ultraviolet absorber, a waterproofing agent and a flame retardant into the color sand and uniformly stirring; (4) placing a mixture into a mold frame, molding by rolling, and curing at room temperature. According to the preparation method provided by the invention, the aeolian sand is taken as the raw material, so that the sources are rich and the waste is turned into treasure; a reactive laminating technology is adopted for performing raw sand treatment and coloring, so that the color sand with different specifications and rich colors can be obtained, and a direction is provided for product diversification; a polyurethane type high molecular polymer is adopted for product binding, and the ultraviolet absorber, the waterproofing agent and the flame retardant are used for assistance so as to enable the obtained products to have excellent physical and chemical properties; the products have the advantages of simple process, and can be prepared by molding by rolling and curing at normal temperature, thereby meeting the requirements for mass production.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a preparation method of building covering materials and the prepared materials. Background technique [0002] Flexible facing brick is a newly developed wall decoration material in recent years. It is a renewable new type of ecological building decoration material that uses colored inorganic mineral powder as the main raw material, adds a small amount of water-based polymer as a modifier, and is cross-linked and formed by microwave irradiation at a certain temperature. The product has good strength and elasticity, light weight, strong appearance, good durability, rich colors and textures, low energy consumption, health and environmental protection, and convenient construction. It can be widely used in the walls of commercial and civil buildings. Surface decoration, especially as an external thermal insulation finish layer has irreplaceable advantages. Compared with...
