Background
In recent years, the heat-insulating and decorating integrated plate has been widely applied to the field of buildings due to the advantages of convenient installation and construction, controllable product factory prefabrication quality and the like. The structure mainly comprises; the facing layer and the insulating layer. The insulation materials used in the method can be roughly classified into A-class fireproof insulation materials (mostly rock wool), B-class fireproof insulation materials and fireproof insulation materials (such as EPS and XPS). In recent years, after a building fire caused by heat-insulating materials occurs, a heat-insulating and decorating integrated plate taking rock wool as a grade A fireproof heat-insulating material as a heat-insulating layer gradually becomes the mainstream of the market.
However, rock wool is soft in texture and high in water absorption rate, so that when the rock wool is used as a heat insulation layer material of the heat insulation and decoration integrated plate, a plurality of problems commonly exist and are troubling integrated plate production enterprises and Party A. One is that the processing technology of the plate is complex, the double surfaces of the rock wool material need to be adhered with the composite calcium silicate plate to increase the integral strength, and the problem that the heat insulation layer is separated from the finish coat due to insufficient bonding strength exists; secondly, the rock wool material has high water absorption rate, so that the heat insulation performance is seriously influenced after water absorption; thirdly, because of the rock wool material reason, the dead weight increases after absorbing water, has the hidden danger of droing.
Based on the above problems, a novel structure form of an integrated heat-insulation and decoration plate and a simple, efficient, safe and reliable preparation method are urgently needed.

Detailed Description
The following description of the embodiments refers to the accompanying drawings, which are included to illustrate specific embodiments in which the invention may be practiced.
As shown in fig. 1 and fig. 2, the embodiment discloses a preparation method of a heat preservation and decoration integrated plate, the preparation method of the heat preservation and decoration integrated plate is used for manufacturing the heat preservation and decoration integrated plate, and the preparation method comprises the following steps:
step 110, arranging the facing layer 1 in a reverse direction and laying the facing layer on the bottom of the mold.
In this step, the material of the facing layer 1 is first arranged in reverse and laid on the bottom of the mold, thereby forming the facing layer 1. Wherein, the facing layer 1 can be made of prefabricated calcium silicate board.
And 120, paving an organic-inorganic composite material raw material composition above the facing layer 1, and forming an insulating layer 2 connected with the facing layer 1 into a whole after shaping.
In the step, an organic-inorganic composite material raw material composition is laid above the finishing layer 1, and the organic-inorganic composite material raw material composition is molded after pressurization and heating to form an insulating layer 2, so that the insulating layer 2 formed after molding is connected with the finishing layer 1 into a whole.
