Technical Field

[0001] The present application relates to the field of tarpaulins, and in particular to a durable PE tarpaulin and a production process thereof. Background Art

[0002] Tarpaulin is a high-strength waterproof material with good toughness and softness. It is often used as canvas. It is made of polyester with polyurethane coating or polyethylene plastic. Tarpaulin usually has sturdy rings at the corners or edges to facilitate rope binding, hanging or covering.

[0003] PE tarpaulin is a polyethylene tarpaulin. During production, the selected materials are fed into a textile machine for spinning, the polyethylene is stretched and rotated to form a limit line, and then the limit line is fed into a weaving machine to weave the tarpaulin.

[0004] Most of the existing PE tarpaulins are single-layer. Although they have waterproof functions, they are all single-layer. When using, when the tarpaulin needs to be moved, the tarpaulin may be scratched by sharp objects, making the tarpaulin unusable. At the same time, when fixing the tarpaulin, excessive pulling on the tarpaulin may affect the service life of the tarpaulin. Summary of the invention

[0005] The purpose of the present application is to solve the problem raised in the above-mentioned background technology that when the tarpaulin needs to be moved, the tarpaulin may be scratched by sharp objects, making the tarpaulin unusable, and at the same time, when the tarpaulin is fixed, excessive pulling on the tarpaulin may affect the service life of the tarpaulin. The present application provides a durable PE tarpaulin and its production process.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions: A durable PE tarpaulin comprises a polyethylene tarpaulin layer 1, a polyethylene tarpaulin layer 2 is arranged on the polyethylene tarpaulin layer 1, a reinforced heat insulation component is arranged between the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2, a reflective layer is sprayed on the polyethylene tarpaulin layer 2, a safety warning strip is fixed to the edge of the reflective layer, and auxiliary fixing components are arranged at the edges of the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2.

[0007] By adopting the above technical scheme, the reinforced insulation component is fixed on the polyethylene tarpaulin layer one, and then the polyethylene tarpaulin layer two is covered on the reinforced insulation component and the polyethylene tarpaulin layer one, and then the auxiliary fixing component is fixed on the reinforced insulation component in the sandwich layer between the polyethylene tarpaulin layer one and the polyethylene tarpaulin layer two. When using the tarpaulin, the tarpaulin is directly laid on the position to be covered, and then fixed to the anchor point by the auxiliary fixing component, and the reinforced insulation component is supported by the auxiliary fixing component, and then the polyethylene tarpaulin layer one and the polyethylene tarpaulin layer two are supported by the reinforced insulation component, so as to strengthen the strength of the tarpaulin, further reduce the possibility of water leakage of the tarpaulin, and at the same time reduce the possibility of wrinkles and water accumulation in the tarpaulin, and reduce the possibility of excessive pulling of the tarpaulin when fixing the tarpaulin.

[0008] Furthermore, the reinforced insulation component includes a flexible metal mesh arranged between polyethylene tarpaulin layer one and polyethylene tarpaulin layer two, the flexible metal mesh is fixedly connected to polyethylene tarpaulin layer one and polyethylene tarpaulin layer two, and a plurality of evenly distributed filling blocks are arranged on the flexible metal mesh, and the filling blocks are evenly distributed in the gaps of the flexible metal mesh and fixedly connected to the flexible metal mesh.

[0009] By adopting the above technical solution, firstly, filling blocks are filled in the gaps of the flexible metal mesh, and the filling blocks fill the holes on the flexible metal mesh. Then, the second polyethylene tarpaulin layer is laid on the flexible metal mesh and the first polyethylene tarpaulin layer, thereby improving the overall strength of the tarpaulin, reducing the possibility of collapse and accumulation of water on the surface when the tarpaulin is covered, and reducing the possibility of sharp objects scratching the entire tarpaulin.

[0010] Furthermore, the filling block is a heat-insulating filling block, and the filling block is glass fiber.

[0012] Furthermore, a wear-resistant layer is provided at the bottom of the second polyethylene tarpaulin layer, the wear-resistant layer is fixedly connected to the second polyethylene tarpaulin layer, and the wear-resistant layer is a wear-resistant rubber block.

[0013] By adopting the above technical solution, when using the tarpaulin, one side of the wear-resistant layer is facing the object. When the tarpaulin is pulled, the wear-resistant layer and the object rub against each other, thereby reducing the friction between the object and the second polyethylene tarpaulin layer when using the tarpaulin, thereby reducing the possibility of damage to the second polyethylene tarpaulin layer.

[0014] Furthermore, a plurality of evenly distributed anti-skid grooves are provided at the bottom of the wear-resistant pad.

[0016] Furthermore, the reflective layer is a reflective paint layer.

[0017] By adopting the above technical solution, reflective paint is sprayed on the side of the polyethylene tarpaulin layer 1 away from the polyethylene tarpaulin layer 2 to form a reflective paint layer, so that when the tarpaulin is in use, ultraviolet rays can be reflected, reducing the possibility of rapid aging of the tarpaulin due to ultraviolet radiation.

[0018] Furthermore, the auxiliary fixing assembly includes a plurality of connection blocks 1 arranged on the edge of the flexible metal mesh, the connection block 1 is rotatably connected to the connection block 2, and the connection block 2 is fixed with a fixing hook.

[0019] By adopting the above technical solution, the fixing hook is directly hung on the anchor point that needs to be fixed, and the flexible metal net is pulled by the fixing hook, thereby reducing the possibility of excessive pulling of the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2 when fixing the tarpaulin, and reducing the possibility of affecting the service life of the polyethylene tarpaulin layer 2 and the polyethylene tarpaulin layer 1 due to excessive pulling.

[0029] When producing the PE tarpaulin, firstly, two PE tarpaulins are produced as the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2, then the reinforced insulation component 5 is fixed on the polyethylene tarpaulin layer 1, and then the polyethylene tarpaulin layer 2 is covered on the reinforced insulation component 5 and the polyethylene tarpaulin layer 1, and then the auxiliary fixing component 6 is fixed on the reinforced insulation component 5 in the sandwich between the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2, and then the reflective layer 4 is sprayed on the surface of the polyethylene tarpaulin layer 2, and finally the safety warning strip is pasted. When using the tarpaulin, the tarpaulin is directly laid at the position to be covered, and then the auxiliary fixing component 6 is used to fix it at the anchor point, and the auxiliary fixing component 6 is used to support the reinforced insulation component 5. The reinforced insulation component 5 is then used to support the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2. When a sharp object cuts through the polyethylene tarpaulin layer 1 or the polyethylene tarpaulin layer 2, the reinforced insulation component 5 blocks the sharp object to reduce the possibility of the sharp object cutting through the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2 at the same time. The reinforced insulation component 5 is used to support the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2, and the reinforced insulation component 5 is fixed to the fixed anchor point by the auxiliary fixing component 6, so that the strength of the tarpaulin can be strengthened, and the possibility of water leakage of the tarpaulin can be further reduced. At the same time, the possibility of wrinkles and water accumulation in the tarpaulin can be reduced, and the possibility of excessive pulling on the tarpaulin when the tarpaulin is fixed can be reduced.

[0030] Reference Figure 2 , Figure 3 and Figure 4 The reinforced insulation component 5 includes a flexible metal mesh 51 arranged between the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2. The flexible metal mesh 51 is fixedly connected to the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2. A plurality of evenly distributed filling blocks 52 are arranged on the flexible metal mesh 51. The filling blocks 52 are evenly distributed in the gaps of the flexible metal mesh 51 and are fixedly connected to the flexible metal mesh 51.

[0031] First, the flexible metal mesh 51 is placed on the polyethylene tarpaulin layer 1, and then the flexible metal mesh 51 and the polyethylene tarpaulin layer 1 are fixedly connected by an adhesive, and then the filling blocks 52 are filled in the gaps of the flexible metal mesh 51, and the filling blocks 52 fill the holes on the flexible metal mesh 51, and then the polyethylene tarpaulin layer 22 is laid on the flexible metal mesh 51 and the polyethylene tarpaulin layer 1, and then fixed by an adhesive, and the flexible metal mesh 51 is sandwiched between the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 22, and the holes of the flexible metal mesh 51 are filled by the filling blocks 52, so that the overall strength of the tarpaulin can be improved, and the possibility of collapse and accumulation of water on the surface when the tarpaulin is covered can be reduced, and the possibility of sharp objects scratching the entire tarpaulin can be reduced.

[0032] Reference Figure 3 and Figure 5 The filling block 52 is a heat-insulating filling block 52, and the filling block 52 is glass fiber. When the filling block 52 is placed in the flexible metal mesh 51, the glass fiber is used as the heat-insulating filling block 52, and the glass fiber filling block 52 supports the holes of the flexible metal mesh 51. By making the filling block 52 with glass fiber and supporting the flexible metal mesh 51 with the filling block 52, the heat-insulating effect can be achieved, and the gap between the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2 can be reduced.

[0033] Figure 2 and Figure 3 The bottom of the polyethylene tarpaulin layer 2 is provided with a wear-resistant layer, which is fixedly connected to the polyethylene tarpaulin layer 2 and is a wear-resistant rubber block. The wear-resistant layer is provided at the bottom of the polyethylene tarpaulin layer 2 and is made of rubber. When the tarpaulin is used, one side of the wear-resistant layer faces the object. When the tarpaulin is pulled, the wear-resistant layer and the object rub against each other. By fixing the wear-resistant layer at the bottom of the polyethylene tarpaulin layer 2, the friction between the object and the polyethylene tarpaulin layer 2 when the tarpaulin is used can be reduced, thereby reducing the possibility of damage to the polyethylene tarpaulin layer 2.

[0034] Reference Figure 2 and Figure 3A plurality of evenly distributed anti-skid grooves are provided at the bottom of the wear-resistant pad 53. Evenly distributed anti-skid grooves are provided on the wear-resistant layer, and the area of ​​the wear-resistant layer is increased by using the anti-skid grooves. When the wear-resistant layer contacts with an object, the contact area with the object is increased. By providing evenly distributed anti-skid grooves on the wear-resistant layer, the contact area between the wear-resistant layer and the object can be increased, and the possibility of sliding between the object and the wear-resistant layer after the tarpaulin is fixed can be reduced.

The reflective coating is sprayed on the side of the polyethylene tarpaulin layer 1 away from the polyethylene tarpaulin layer 2 to form a reflective coating layer. The reflective coating layer is UV500 reflective coating, which has good ultraviolet reflection and flexibility. By spraying the reflective coating on the polyethylene tarpaulin layer 1 to form a reflective coating layer, the ultraviolet rays can be reflected when the tarpaulin is used, reducing the possibility of the tarpaulin being irradiated by ultraviolet rays and aging quickly.

When fixing the tarpaulin, the fixing hook 63 is directly hung on the anchor point to be fixed, and the flexible metal mesh 51 is pulled by the fixing hook 63, so that the flexible metal mesh 51 supports the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2. By using the fixing hook 63 to drive the connecting block 2 62, the connecting block 2 62 pulls the connecting block 1 61, and the connecting block 1 61 pulls the flexible metal mesh 51, so that the flexible metal mesh 51 supports the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2, thereby reducing the possibility of excessively pulling the polyethylene tarpaulin layer 1 and the polyethylene tarpaulin layer 2 when fixing the tarpaulin, and reducing the possibility of affecting the service life of the polyethylene tarpaulin layer 2 and the polyethylene tarpaulin layer 1 due to excessive pulling.
