Concrete decorating plate and preparation method thereof

Abstract

The invention provides a concrete decorating plate and a preparation method thereof. The concrete decorating plate comprises a concrete structure layer, an interface layer and a decorating layer. Raw materials of the concrete structure layer comprise ultrahigh strength concrete and phase change and energy storage particles, and the mass ratio of the phase change and energy storage particles to the ultrahigh strength concrete is 2%-10%; the interface layer is of a net-shaped structure and is arranged on the concrete structure layer; the decorating layer is arranged on the interface layer and the concrete structure layer, and raw materials of the decorating layer comprise, by weight, 300-550 parts of cement, 700-950 parts of 20-40-mesh quartz sand, 240-310 parts of 40-70-mesh quartz sand, 15-22 parts of a water reducing agent, 0.1-0.7 part of cellulose ether and 190-240 parts of water. According to the concrete decorating plate, the concrete structure, the interface layer and the decorating layer matched with the concrete structure layer and the interface layer are adopted, the strength of the concrete decorating plate is improved, and then the thickness of the concrete decorating plate is decreased; the phase change and energy storage particles are added into concrete, phase change heat absorption or heat release is generated by the phase change and energy storage particles, the cold and heat resistance of the concrete decorating plate is improved, an environment temperature adjusting effect is achieved, and then the durability of the concrete decorating plate is improved.

Description

technical field

[0001] The invention relates to a concrete decorative board and a preparation method thereof. Background technique

[0002] Among the decorative panels of existing buildings, especially public buildings, stone decorative panels are mainly used. However, the collection, transportation and processing of stone materials are difficult and costly; and stone materials are non-renewable resources, and mining seriously damages the ecological environment. Therefore, concrete-based decorative panels have become a key research object in the field of decorative panels. However, due to the harsh service environment of concrete decorative panels, the main problem of the current concrete decorative panels is that the durability is not ideal, and problems such as falling off and damage are prone to occur, which in turn affects its performance. Contents of the invention

[0003] Based on this, it is necessary to provide a durable concrete decorative panel and a preparatio...
