In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer.

The energy-saving sound-insulation mesh fabric and the preparation method thereof according to the embodiment of the invention are specifically described below.
The preparation method of the energy-saving sound insulation mesh fabric mainly comprises the following steps: and preparing a first grid layer, a second grid layer and a third grid layer, and then overlapping and bonding the first grid layer, the second grid layer and the third grid layer.

The first mesh layer can be woven by basalt fibers, or glass fibers, or a mixture of basalt fibers and glass fibers. When the first grid layer is woven by mixing basalt fibers and glass fibers, the using amount of the basalt fibers and the glass fibers can be 1: 1-3; the cells of the first mesh layer may be of various regular polygons, for example: triangular, quadrilateral, hexagonal, etc. Preferably, the cells of the first mesh layer are triangular.
The second mesh layer may be woven from basalt fibers, or from glass fibers, or from a mixture of basalt fibers and glass fibers. When the second grid layer is woven by mixing basalt fibers and glass fibers, the using amount of the basalt fibers and the glass fibers can be 1: 1-3; the cells of the second mesh layer may be of various polygonal shapes, for example: triangular, quadrilateral, hexagonal, etc. Preferably, the meshes of the second mesh layer are quadrilateral or hexagonal.
The third mesh layer may be woven from basalt fibers, or from glass fibers, or from a mixture of basalt fibers and glass fibers. When the third grid layer is woven by mixing basalt fibers and glass fibers, the using amount of the basalt fibers and the glass fibers can be 1: 1-3; the cells of the third mesh layer may be of various polygonal shapes, for example: triangular, quadrilateral, hexagonal, etc. Preferably, the cells of the third mesh layer are triangular.
It should be noted that, the first mesh layer and the third mesh layer on both sides of the second mesh layer are both triangular, and when the meshes of the second mesh layer are quadrilateral or hexagonal, the noise absorption capacity of the energy-saving sound-insulation mesh cloth can be effectively improved, thereby ensuring that the mesh cloth has a good sound-insulation effect. Furthermore, the mechanical strength, toughness and the like of the mesh cloth can be improved by weaving the mesh layer with a mixture of basalt fibers and glass fibers, and the sound insulation effect of the sound insulation mesh layer can be improved by utilizing the loose texture of the basalt fibers.
The adhesive may include plastic, stabilizer and perlite powder. In detail, the coating composition can comprise the following components in parts by weight: 100-120 parts of plastic, 10-30 parts of stabilizer and 10-20 parts of perlite powder. The plastic cement can successfully bond the grid layers, the perlite powder can be uniformly attached to the grid layers, and the mechanical strength, toughness and the like of the energy-saving sound-insulation grid cloth can be further enhanced.
The perlite powder is added into the adhesive to absorb certain noise by utilizing tiny cracks in the perlite powder, so that the sound insulation effect of the energy-saving sound insulation grid layer is improved. Preferably, the particle size of the perlite powder can be 700-800 meshes, and the perlite powder is controlled and added according to the particle size, so that the perlite powder can be dispersed in the plastic more uniformly, and sufficient cracks in the perlite powder can be ensured, and the grid cloth is ensured to have a good sound insulation effect.

Note that, the first drying roller 200 and the second drying roller 300 have a heating function, for example: the surfaces of the first drying roller 200 and the second drying roller 300 may be provided as heat-generating electrode sheets, etc.; the temperature for drying may be 50-60 deg.C. When the roller type dryer 10 is used for drying, the first grid layer, the second grid layer and the third grid layer can be attached to each other more tightly after drying, and the mechanical property, the toughness and the like of the energy-saving sound-insulation grid cloth are improved.
When the energy-saving sound insulation mesh cloth is dried, the stacked mesh cloth is sequentially arranged through the first crack 110, the second crack 120 and the third crack 130, and then the drying can be completed. It should be noted that the rate of mesh fabric delivery from each nip can be adjusted according to the specific drying rate; or the mesh fabric may be passed through the drying nip of the roller dryer 10 several times, for example: 2 times, 3 times, etc.
