Technique of manufacturing artificial cultured stone

Abstract

The invention discloses a production process for an artificial cultural stone, comprising the following steps: preparation of a die, preparation of slurry, preparation of stuffing, die-coloring, guniting or grouting, filler-filling, secondary guniting or grouting, vibration and shaping, ustulation and shaped product-packing. The invention has the advantages that the artificial cultural stone manufactured according to the technical scheme of the invention has a surface with high density, low water absorption, a good weatherability, a high strength surface, a strong anti-ultraviolet ability, good forest resistance, good anti-aging property and a uniform and coordinated color; the artificial cultural stone can floats in the water due to the hard surface and a low specific gravity in the middle; the pasting surface pasting to the building surface is rough which is in favor in pasting, therefore, the pasting is more stable and dose not exfoliate easily; the invention also has a good heat-insulation and a preservation which can replace the insulating layer, thus not only reducing the building cost, but also conforming with the requirement of the national environmental protection and energy conservation.

Description

technical field [0001] The invention relates to a production process of synthetic stone, in particular to a production process of light artificial cultural stone that can float on the water surface. Background technique [0002] With social progress and economic development, as well as urban construction and people's increasing demand for beautification of the living environment at home, in order to meet this growing demand, many construction industries often use stone with natural stone patterns as buildings. It is used for surface and interior decoration, but natural stone resources are limited, and its excessive mining has brought many unfavorable factors to the surrounding environment of the mining area, such as the felling of mountain vegetation, which causes the mountain rock and soil layer to be soft, causing mudslides and so on. Therefore, in recent years, a kind of artificial cultural stone has appeared to replace natural stone as building decoration and decoration....

[0002] With social progress and economic development, as well as urban construction and people's increasing demand for beautification of the living environment at home, in order to meet this growing demand, many construction industries often use stone with natural stone patterns as buildings. It is used for surface and interior decoration, but natural stone resources are limited, and its excessive mining has brought many unfavorable factors to the surrounding environment of the mining area, such as the felling of mountain vegetation, which causes the mountain rock and soil layer to be soft, causing mudslides, etc.

Therefore, in recent years, a kind of artificial cultural stone has appeared to replace natural stone as building decoration and decoration. This artificial cultural stone is artificially made of cement, sand, ceramsite and other materials through a certain process into artificial cultural stone with natural stone texture. The production process of this kind of cultural stone is generally to mix cement, sand, ceramsite (or perlite) and water with a mixer and then pour it directly into the mold. The proportion of cultural stone is difficult to control. It is heavy, which brings inconvenience to transportation and handling. At the same time, it is difficult to attach to the surface of the building, and it is easy to fall off, which brings certain safety hazards.

If you want to achieve a very light specific gravity, even close to the specific gravity of water, then a large amount of ceramsite must be added to the filling material. Even in this way, the specific gravity of water cannot be achieved, and the filling material is poured in the mold because the specific gravity of cement is too small. , the air bubbles in the filler cannot be eliminated through vibration, which makes the surface of the cultural stone form honeycomb holes, resulting in unclear stone patterns that the cultural stone should have. It can be said that it is not a cultural stone at all, and its strength is correspondingly reduced.

At present, none of the cultural stone manufacturers at home and abroad can produce cultural stones that can float on the water and have no honeycomb holes on the surface, which is very strong.
