Flexible stone and manufacturing method thereof

Abstract

The invention discloses a flexible stone and a manufacturing method thereof. The flexible stone comprises the following raw materials: 20 to 40 percent of cement, 2 to 15 percent of latex powder, 0.3 to 2 percent of organic silicon water repellent, 0.1 to 2 percent of fiber and the balance of filler such as waste building cement blocks, waste blocks of a stone plant, cinder, waste powder of a ceramic plant, quartz sand and the like. The manufacturing method comprises the following steps of: crushing the filler, mixing the crushed filler and other raw materials, and adding 15 to 30 percent of water into the mixture to obtain composite slurry; and coating, pouring or extruding the composite slurry on a stone texture die, solidifying the composite slurry at normal temperature and then releasing a solidified object from the die to obtain the flexible stone. The flexible stone has light weight, surface density of less than 8kg / m<2> and extremely good stone simulating effect. The flexible stone can be stuck by using polymer cement mortar without dry-hanging assembly, and is particularly suitable for decoration of an outer wall. The used raw materials have no harm to the human body, have no radioactive hazard, do not generate volatile gas, and are also suitable for indoor decoration. The flexible stone makes full use of building wastes, and is economic and environment-friendly.

Description

technical field [0001] The invention relates to a building decoration material and a manufacturing method thereof, in particular to a flexible imitation stone decorative surface material and a manufacturing method thereof. Background technique [0002] As a decorative material, natural stone has the characteristics of natural color and texture, and is more and more popular among people. It is widely used in the decoration of building facades and residential lobbies. [0003] However, natural stone is self-heavy, and there are many dangers in the application of building exterior walls, especially high-rise building exterior walls. If a fire breaks out in a building, the high temperature generated by the fire will soften or even melt the stainless steel plate or other metal structure on which the stone slab is installed, and the strength will be significantly reduced, making it unable to support the heavy stone slab. Like this, slate can form " slate rain " and falls from hig...

AI Technical Summary

Problems solved by technology

This increases the difficulty of design and construction, resulting in the high cost of natural stone for exterior wall decoration

[0004] The biggest problem with natural stone as interior decoration is that natural stone has a certain degree of radioactivity, which will affect human health. At the same time, due to its weight, installation is also difficult

[0005] The mining of natural stone will greatly destroy surface resources; during processing and production, a large amount of dust will be generated, which will also adversely affect the health of production personnel

Moreover, the mining of natural stone raw materials will also cause certain adverse effects on the environment.

[0006] However, although the existing artificial stone overcomes the radioactive defect of natural stone, its self-weight is also relatively large, and its weather resistance is poor, so it is not suitable for exterior wall decoration, and its installation process is the same as that of natural stone.

[0007] Regardless of whether it is natural stone or existing artificial stone, it is difficult to recycle after being discarded, forming a large amount of construction waste, which is not good for the environment
