Embodiment Construction

[0036] Stone composite panel of the present invention, as figure 1 As shown, it is composed of a stone panel 1 and a base plate 3 including cement components, through a bonding layer 2 including viscosity-modified cement as a bonding material, and then pressed and composited. Composite panels. The stone constituting the panel 1 can be granite, marble or marble decorative board, its surface 11 is polished, and its back side 12 will be roughened, or several lengths and widths are engraved on the back side 12 and are (0.5~0.8 )mm groove line.

[0037] At the same time, prepare the mixed cementitious material that constitutes the bonding layer 2, including high-strength and fast-hardening 2.5Mpa cement, as the main material, such as sulphoaluminate cement, and add a polyacrylate aqueous solution with a weight of 40% to 50% of the cement. , the concentration of the aqueous solution is 2% to 5%, and it is stirred into a slurry, so that the viscosity-modified cement slurry can incr...

Abstract

The invention relates to a fiber cement-stone compound plate and a product thereof. The product comprises a panel 1 and a cement-containing base material plate 3, and the compound plate is formed by bonding through a bonding layer 2 constituted by polyacrylic ester-modified cement slurry and performing pressure forming, wherein the preparation of the base material plate 3 is as follows: sequentially injecting materials of various layers into a mold frame for respectively forming a bottom layer, a lower interlayer, a middle layer, an upper interlayer and a surface layer, wherein the bottom layer and the surface layer are made of modified cement, the upper and the lower interlayers are of glass fiber nets, the components of the middle layer comprise cement, light ceramsite, fiber and polyacrylic ester emulsion or the middle layer is made of foam cement mortar with gas content of 20%-50%; and the thickness of the base material plate 3 is 12mm-16mm, and the base material plate is further bonded with the panel made of stone for forming the compound plate. The product is high in bending strength and flexural strength, low in thermal expansion coefficient and hygroscopic expansion coefficient, heat-insulating, weather-resistant, simple and convenient to mount and suitable for various floors.

Description

technical field [0001] The invention relates to a stone composite board, in particular to a production method and a product of a composite board made of cement and stone. Background technique [0002] Stone, especially its board, in order to maintain its rigidity and high strength and improve its bending resistance, the way of stone composite board is often used. But there are many types and methods of compounding. Combining with organic materials, the performance is improved a lot, but the cost is increased; using inorganic cementitious materials, especially cement, to modify the cost is greatly reduced, but the performance is difficult to ideal. The cost of using metal to strengthen, such as aluminum honeycomb panel-stone composite panel, is still higher than that of inorganic composite materials. When choosing composite materials, the thermal expansion coefficient and the similarity of the wet expansion coefficient of the two should also be considered. Although reports...
