Cement brick embedded with metal beads and preparation method thereof

Abstract

The invention particularly relates to a cement brick embedded with metallic beads and a preparation method thereof, and belongs to the preparation technical field of building and ornament materials. The cement brick embedded with the metallic beads comprises a surface layer, a transition layer and a bottom layer. The surface layer, the transition layer and the bottom layer are formed by preparing water soluble resin and cement at a specific ratio, and the dry shrinkage value of the transition layer is ranged between that of the bottom layer and that of the surface layer. The problem that cracks occur due to the fact that the dry shrinkage values are greatly different from one another when the surface layer and the bottom layer are directly bonded is solved. Hence, the surface layer and the bottom layer can be better bonded. When the surface layer is prepared, a small amount of PLA-PEG is added to be matched with the water solubility epoxy resin for use, the surface layer is made more smooth, the color is brighter, and the anti-cracking, the waterproof and acid-resisting capacity is obviously improved. Materials of the surface layer, the transition layer and the bottom layer are limited specifically, and the surface tension between the surface layer, the transition layer and the bottom layer is matched with each other so that a superior bonding effect can be achieved. Meanwhile, the thickness proportion of the surface layer, the transition layer and the bottom layer is adjusted, and the overall strength can be further improved.

Description

technical field [0001] The invention particularly relates to a low-cost, high-performance cement brick embedded with metal beads and a preparation method thereof, belonging to the technical field of preparation of building decoration materials. Background technique [0002] With the development of the country's economic life, the materials used in interior and exterior design have involved various industries such as steel, non-ferrous metals, chemicals, textiles, wood, ceramics, plastics, and glass. People's emphasis and emphasis on the spirit of the theme of interior and exterior design also requires new materials with great personality and moderate cost to realize. As far as wall and floor decoration is concerned, there are many types of materials that can be used, such as ceramic glazed tiles, marble, and granite facing tiles. However, the above-mentioned materials are difficult to make new breakthroughs in decorative effects, and the cost is high. It is quite necessary ...
