Description
Technical Field
The invention relates to a manufacturing method of a heat-insulation decorative plate with a mechanical connection structure, which is applied to the field of production of heat-insulation decorative plates.
Background
China is in the prosperous period of buildings, the building construction area built every year is as high as 20-30 hundred million square meters, and exceeds the sum of the annual building areas of all developed countries. More than 80% of buildings are high energy consumption buildings, and the energy consumption accounts for more than 40% of the total social energy consumption and is the top of various energy consumptions. Therefore, building energy conservation becomes one of the mainstream of the world energy conservation and surge, and the building energy conservation technology becomes an important content of the development of the building technology in the world nowadays. One important aspect of building energy conservation is the thermal insulation of building walls. The heat-insulating decorative board is a novel heat-insulating decorative material developed in recent years, and has a large number of applications in the market due to the characteristics of good decorative effect, good heat-insulating property, simple and rapid construction and the like. The related industry standards are also exported one after another, including product standards JG/T287-2013 and JGJ/T350-2015. The existing heat-insulating decorative board is generally a two-layer structure formed by a heat-insulating layer 2 ' and a surface board layer 1 ' or a three-layer structure formed by a bottom board layer 3 ', a heat-insulating layer 2 ' and a surface board layer 1 ', all layers of the heat-insulating decorative board are bonded together by adopting an adhesive, and the heat-insulating decorative board is fixed on a base wall body 4 ' by adopting an installation mode which is mainly pasted and assisted by anchoring during installation, namely, the heat-insulating decorative board is pasted on a wall surface by adopting bonding mortar firstly, then the anchoring part 5 ' is arranged on the side surface of the heat-insulating decorative board by adopting, one end of the anchoring part is fixed on the wall body, and the other end of the anchoring part is connected with the heat. The other end of the anchoring piece and the anchoring part of the heat-insulation decorative plate are generally in two types, one is directly inserted into the heat-insulation layer or between the bottom plate layer and the heat-insulation layer (as shown in figure 1), the other is that the side surface of the panel layer is provided with an installation groove, and then the other end of the anchoring piece is inserted into the installation groove (as shown in figure 2). The first anchoring mode is easy to loose due to low strength of the heat-insulating layer, and cannot achieve the anchoring effect; the second anchoring mode is that a groove is formed in the panel, and because the groove is limited by the thickness of the panel, the groove formed in the side surface of the panel is easy to break, and the anchoring piece inserted in the mounting groove still has the problems of low anchoring force and unreliable connection between the anchoring piece and the panel. And the panel layer and the heat-insulating layer are usually bonded by adopting an organic adhesive, so that the panel layer and the heat-insulating layer are separated and the panel layer falls off in case of any condition of aging of the heat-insulating layer material, aging of the organic adhesive, great reduction of the strength of the adhesive caused by improper proportioning of the adhesive or exceeding of the application time of the adhesive beyond the operational time requirement in the production process, and the like. Especially when taking place the conflagration, in case the heat preservation is burnt out, there will not any connection between panel layer and the bottom plate layer, also easily causes the panel layer to drop, causes very big difficulty for the fire rescue.
Therefore, it is desirable to provide a method for manufacturing a thermal insulation decorative board with a mechanical connection structure, which can manufacture a thermal insulation decorative board with a mechanical connection structure that can safely and reliably connect a panel layer, a thermal insulation layer, and a floor layer, and which is simple in manufacturing process without modifying existing equipment and production lines.
