[0001] The present invention relates to the technical field of sheet production and processing, and specifically to a large-sized ultra-thin composite stone and its processing technology. Background Art

[0002] Stone has become a high-grade building decoration material with its natural texture and color. With the improvement of stone mining and processing technology, the surface can be polished very brightly, and the stone slabs can also be cut very thin. Although the raw material sources of stone are abundant, the current raw material prices are still expensive, resulting in a relatively high price of stone slabs. Usually, in order to improve the sound insulation effect and quality, the thickness of the stone slabs is increased, but in this way, the stone slabs are heavy and troublesome to construct and use. Therefore, how to develop a method to reduce the weight of composite stone slabs, improve the sound insulation effect, and achieve efficient processing and production of composite stone slabs is a technical problem that we urgently need to solve.
