Abstract

The invention discloses a composite stone material and a preparation method of the same. The composite stone material includes a stone material base layer and a sheet material layer, wherein the composite stone material includes the following raw materials, by weight: 20-40 parts of a stone material, 2-20 parts of inorganic micro powder, 2-20 parts of emulsion, 0.1-1.0 part of an additive and 4-8 parts of a binder. The preparation method includes the steps of: uniformly stirring the inorganic micro powder, the additive and other components according to certain process, and performing die-filling, allowing the materials to stand to foam the materials, maintaining the materials, and drying, cutting and polishing the materials to obtain the light-weight energy-saving sheet material; and binding the stone material to the light-weight heat-preservation sheet material through the binder, wherein the stone material is the decorative surface layer and the light-weight heat-preservation sheet material is a lining layer, to produce the composite stone material when the binder is hardened. The preparation method is simple. The composite stone material is excellent in comprehensive mechanical performance and is low in heat conductive coefficient, has a heat-preservation and -insulation effect, is green, energy-saving and environment-friendly, and can be widely used in various indoor and outdoor decoration projects having strict energy-saving demand.

Description

technical field [0001] The invention relates to a composite stone material with thermal insulation effect and a preparation method thereof, belonging to the technical field of building energy-saving decorative materials. Background technique [0002] Stone is a kind of decorative building material, and there are more and more applications of using stone on the wall by wall-mounted installation methods. Although stone has good decorative properties, the thermal conductivity of stone itself is relatively high. For buildings with high energy-saving requirements, there is a disadvantage of high building energy consumption. Therefore, while pursuing the decorative effect, how to improve the thermal insulation effect of stone materials and reduce the energy consumption of buildings is also a technical problem urgently needed to be solved by those skilled in the art. Contents of the invention [0003] Aiming at the above defects in the prior art, the present invention proposes a...
