Description

Technical Field

[0001] The utility model relates to the technical field of space cloth structures, in particular to a wear-resistant space composite material. Background Art

[0002] The structure of the space cloth includes a middle layer of wire drawing mesh (space base cloth) and a mask layer laminated on both sides of the wire drawing mesh layer. The mask layer can improve the wear resistance and bending resistance of the surface of the space cloth. During lamination, since the width of the mask layer is smaller than that of the wire drawing mesh, the paste between the two is easily squeezed out and contaminates the wire drawing layer and laminating equipment, affecting the quality of the space cloth; it will also reduce the peel strength of the edge of the space cloth, reducing the available width of the space cloth, and not meeting the size specifications after cutting, reducing the product yield. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a wear-resistant space composite material with no glue overflowing at the edge.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a wear-resistant space composite material, comprising a first surface film layer, a second surface film layer, a space base fabric, a second bottom film layer and a first bottom film layer, which are sequentially stacked from top to bottom with their center lines aligned;

[0005] The width of the first mask layer and the width of the space base fabric are both greater than the width of the second mask layer;

[0006] The width of the first bottom film layer and the width of the space base fabric are both greater than the width of the second bottom film layer.

[0007] Wherein, the width of the first mask layer is 20 to 30 mm wider than the width of the second mask layer.

[0008] Wherein, the width of the first bottom film layer is 20 to 30 mm wider than the width of the second bottom film layer.

[0009] Wherein, both sides of the second mask layer and the second base film layer are provided with a paste layer.

[0010] Wherein, the width of the space base fabric is greater than the width of the first surface film layer and the first bottom film layer.

[0011] Wherein, the width of the space base fabric is 20 to 40 mm wider than the width of the first mask layer.

[0012] Wherein, the width of the space base fabric is 20 to 40 mm wider than the width of the first bottom film layer.

[0013] The beneficial effect of the utility model is that the wear-resistant spatial composite material of the utility model is provided with an intermediate layer (a second surface film layer and a second bottom film layer) and a surface layer (a first surface film layer and a first bottom film layer) on both sides of the spatial base cloth in sequence, and the widths of the spatial base cloth and the surface layer are both greater than the width of the intermediate layer, so that the paste used for bonding each layer is always located between the spatial base cloth and the surface layer during extrusion, preventing the paste from overflowing from the edge of the spatial cloth and sticking to the equipment, thereby avoiding the problems of sticking materials and rotten edges during the processing, and the need to frequently stop the machine to wipe the large cylinder, thereby improving production efficiency and yield rate.

[0017] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0018] Please refer to Figure 1 , a wear-resistant space composite material, comprising a first face film layer, a second face film layer, a space base fabric, a second bottom film layer and a first bottom film layer, which are sequentially stacked in a center line aligned from top to bottom;

[0019] The width of the first mask layer and the width of the space base fabric are both greater than the width of the second mask layer;

[0020] The width of the first bottom film layer and the width of the space base fabric are both greater than the width of the second bottom film layer.

[0021] From the above description, it can be seen that the beneficial effects of the utility model are: the wear-resistant space composite material of the utility model is stacked in sequence from top to bottom with the first mask layer, the second mask layer, the space base cloth, the second bottom film layer and the first bottom film layer aligned in the center line, and the width of the first mask layer and the width of the space base cloth are both greater than the width of the second mask layer; the width of the first bottom film layer and the width of the space base cloth are both greater than the width of the second bottom film layer, so that the paste used for laminating each layer is always located between the space base cloth, the first mask layer and the first bottom film layer during extrusion. Preventing the paste from overflowing from the edge of the space cloth and sticking to the equipment, thereby avoiding the problems of sticky materials and rotten edges during the processing process, as well as the need to frequently stop the machine to wipe the equipment, thereby improving production efficiency; it also avoids a large amount of cutting caused by insufficient peeling strength at the edge of the space cloth, so that the available space cloth meets the size specifications and improves the yield rate.

[0022] Traditionally, a single-layer thick calendered film is used for lamination. The thick calendered film is prone to air spot problems. During lamination, the air spots are easily converted into semi-perforations by heat. Some semi-perforations are small or hidden and difficult to detect, increasing the risk of air leakage in finished product processing. The utility model uses two layers of film without reducing the original weight, which can avoid the semi-perforation anomalies caused by the air spot problem caused by the thick calendered film and reduce the risk of air leakage in the subsequent finished product.

[0023] Furthermore, the width of the first mask layer is 20 to 30 mm wider than the width of the second mask layer.

[0024] Furthermore, the width of the first bottom film layer is 20 to 30 mm wider than the width of the second bottom film layer.

[0025] From the above description, it can be seen that if the width of the first surface film layer and the first bottom film layer is too wide, the production cost will increase; if the width is too narrow, the squeezed paste cannot be completely covered.

[0026] Furthermore, paste layers are provided on both sides of the second surface film layer and the second bottom film layer.

[0027] From the above description, it can be seen that coating both sides of the second surface film layer and the second bottom film layer with paste can ensure the peeling strength and avoid insufficient peeling caused by a small area not being coated with paste or too little paste, resulting in delamination when the finished product is inflated.

[0028] Furthermore, the width of the space base fabric is greater than the width of the first surface film layer and the first bottom film layer.

[0029] From the above description, it can be seen that the width of the spatial base cloth is greater than the width of the first surface film layer and the first bottom film layer. On the one hand, it can prevent the film from sticking to the roller after heating, which causes trouble in cleaning the machine; on the other hand, if the film width is greater than the width of the spatial base cloth, the bottom film will be bonded together after heat sealing, and the upper and lower layers of mesh cloth will be difficult to separate, and the three-dimensional structure effect of the spatial composite material cannot be achieved.

[0030] Furthermore, the width of the space base fabric is 20 to 40 mm wider than the width of the first mask layer.

[0031] Furthermore, the width of the space base fabric is 20 to 40 mm wider than the width of the first base film layer.

[0032] Furthermore, the first mask layer, the second mask layer, the first bottom film layer and the second mask layer are all made of PVC material.

[0033] Please refer to Figure 1Embodiment 1 of the utility model is: a wear-resistant space composite material, comprising a first face mask layer 1, a second face mask layer 2, a space base fabric 3, a second bottom film layer 4 and a first bottom film layer 5 which are stacked in sequence with center lines aligned from top to bottom, and a paste layer 6 is provided on both sides of the second face mask layer 2 and the second bottom film layer 4; the width of the first face mask layer 1 is 1880 mm; the width of the second face mask layer 2 is 1850 mm; the width of the space base fabric 3 is 1920 mm; the width of the second bottom film layer 4 is 1850 mm; the width of the first bottom film layer 5 is 1870 mm.

[0034] In summary, the wear-resistant space composite material provided by the utility model has the following advantages:

[0035] 1. Through the specific layer structure and layer width, the paste used for laminating each layer is always located between the space base cloth, the first surface film layer and the first bottom film layer during extrusion, avoiding the problems of sticking, rotten edges and equipment downtime for wiping caused by paste overflow, avoiding large-scale cutting, and improving production efficiency and yield rate.

[0036] 2. The utility model changes to two-layer film without reducing the original weight, which can avoid the half-perforation anomaly caused by the air spot problem caused by calendering thick film, and reduce the risk of air leakage in the subsequent finished product.

[0037] 3. Apply paste on both sides of the second mask layer and the second base film layer to avoid insufficient peeling due to a small area not being coated with paste or too little paste being applied, which will cause delamination when the finished product is inflated.

[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
