Embodiment 1

[0026] Decorative layer formula: 600 parts of dam cement, 820 parts of quartz sand with a particle size of 20-40 mesh, 230 parts of river sand with a particle size of 70-140 mesh, 210 parts of river sand with a particle size of 325 mesh, 50 parts of water reducing agent, and 140 parts of water , 1.9 parts of pigment iron oxide brown.

[0027] Preparation: Stir and mix the decorative layer formula evenly and spread it on the mold, and the decorative layer is formed after the uniform distribution;

[0028] Application: Lay interface layer grid cloth on the finished decorative layer, and then evenly distribute ultra-high-strength concrete on the structural layer (its main component is similar to the decorative layer) on the grid cloth, lightly vibrate for 5-15s and lay flat The back bolts are pre-buried, and the curing is carried out after the cloth is finished. After the curing reaches the demoulding strength, the demoulding is carried out, and the high-strength concrete decorat...

Abstract

The invention relates to external wall decoration of a building and specifically relates to a decorative layer for a brown high-strength concrete decorative hanging plate. According to the scheme, the decorative layer is prepared from the following raw materials in parts by weight: 400-800 parts of cement, 710-950 parts of 10-40-mesh sand, 160-240 parts of 70-140-mesh sand, 110-260 parts of 325-mesh sand, 45-110 parts of a water reducer, 120-160 parts of water and 0-4 parts of pigment iron oxide brown. On the basis of the prior part, the matching form of cement base stock and multi-level specific sand is adopted, and the decorative layer can be tightly connected with the structural layer of an external wall hanging plate, so that the connecting strength can be greatly increased and the stripping can be avoided.

Description

technical field [0001] The invention relates to building exterior wall decoration, in particular to a decorative layer of a brown high-strength concrete decorative hanging board. Background technique [0002] Among the existing building exterior wall decorative hanging panels, stone decorative hanging panels occupy a considerable market share. However, the collection, transportation, and processing of stone are difficult, the preparation process is complicated, and the cost is high; and stone is a non-renewable resource, and mining seriously damages the ecological environment. With the improvement of people's concept of ecology and environmental protection, as well as the enhancement of resource conservation and protection awareness, concrete-based imitation stone decorative hanging panels have also become a key research object in the field of decorative panels, and various types of panels have been developed. The product. However, concrete decorative hanging boards have v...
