preparation example Construction

[0045] see figure 1 , the present invention also provides a preparation method of the above-mentioned imitation stone concrete decorative board, comprising the following steps.

[0046] Step S1, coating the inner wall of the mold with a release agent and drying it. Step S1 is a pretreatment step of the mould.

[0047] This is conducive to the demoulding of the subsequent imitation stone concrete decorative board. If the step S2 is performed before the release agent is dried, the release agent may float up, thereby affecting the smooth progress of the release agent and the strength of the imitation stone concrete decorative board.

[0048] Preferably, the mold is a glass panel mold. The use of the mold can make the gloss of the decorative layer very high, and the surface of the obtained decorative layer is similar to a polished stone surface, and can replace stone for interior and exterior wall decoration of buildings.

[0049] Step S2, spraying the raw material of the deco...

Embodiment 1

[0063] The stone-like concrete decorative board includes a concrete structure layer, an interface layer and a decorative layer arranged in sequence.

[0064] The raw material of the concrete structure layer is super high strength concrete. The interface layer is crack-resistant fiber mesh cloth. The decoration layer includes a mortar structure layer and a plurality of decoration parts distributed on the outer surface of the mortar structure layer, and at least part of the outer surface of the mortar structure layer is exposed. The raw materials of the mortar structure layer are calculated in parts by weight, including 850 parts of white cement, 650 parts of 20-40 mesh quartz sand, 250 parts of 40-70 mesh quartz sand, 100 parts of 325 mesh quartz sand, and 90 parts of polycarboxylate superplasticizer , 0.2 parts of cellulose ether, 105 parts of water and 5.5 parts of titanium dioxide. The raw materials of the decoration part are calculated in parts by weight, including 850 pa...

Embodiment 2

[0071] The stone-like concrete decorative board includes a concrete structure layer, an interface layer and a decorative layer arranged in sequence.

[0072] The raw material of the concrete structure layer is super high strength concrete. The interface layer is steel mesh. The decoration layer includes a mortar structure layer and a plurality of decoration parts distributed on the outer surface of the mortar structure layer, and at least part of the outer surface of the mortar structure layer is exposed. The raw materials of the mortar structure layer are calculated in parts by weight, including 900 parts of white cement, 700 parts of 20-40 mesh quartz sand, 300 parts of 40-70 mesh quartz sand, 150 parts of 325 mesh quartz sand, and 110 parts of polycarboxylate superplasticizer , 0.3 parts of cellulose ether, 110 parts of water and 6 parts of iron yellow. The raw materials of the decoration part are calculated in parts by weight, including 900 parts of white cement, 700 par...

Abstract

The present invention discloses imitation stone concrete decorative boards and a preparation method thereof. The imitation stone concrete decorative boards and preparation method thereof comprises concrete structure layers, interface layers and decorative layers. The interface layers are in mesh structures and arranged on the concrete structure layers. The decorative layers are arranged on the interface layers, the decorative layers comprise mortar structure layers and a plurality of decorative parts distributed on the outer surface of the mortar structure layers, and the mortar structure layers at least expose parts of the outer surfaces. The raw materials of the mortar structure layers and the raw materials of the decorative parts comprise the following raw materials in parts by weight: 800-950 parts of cement, 600-900 parts of quartz sand at 20-40 meshes, 200-350 parts of quartz sand at 40-70 meshes, 80-130 parts of a water reducing agent, 0.1-0.6 part of cellulose ether, 90-135 parts of water and 5-15 parts of pigments. The pigments in the raw materials of the mortar structure layers and raw materials of the decorative parts are all one of iron black, iron yellow and titanium white. The pigments in the raw materials of the mortar structure layers and the raw materials of the decorative parts are not the same kind. In the imitation stone concrete decorative boards, the decorative layers obtained by using the raw materials of the decorative layers are strong in strength and thus good in durability. Besides, the decorative layers use different colors to embellish with each other to form the decorative board effects of imitation granite.

Description

technical field [0001] The invention relates to a stone imitation 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. The most important problem for the current concrete decorative board to replace stone is how to improve its durability and realize the aesthetics of the natural texture of stone. Contents of the invention [0003] Based on this, it is necessary to provide a stone imitation concrete decorative panel with good durability and imitation stone veneer and a preparation method thereof. [000...
