Abstract
Description
Technical Field
[0001] The utility model relates to the field of PE tarpaulins, in particular to a heat-insulating and moisture-proof PE tarpaulin. Background Art
[0002] Tarpaulin (also known as waterproof cloth) is a high-strength, flexible, and waterproof material. PE tarpaulin is typically made from HDPE (high-density polyethylene), a material with a high operating temperature, excellent hardness, mechanical strength, and chemical resistance. PE tarpaulin is a woven PE fabric coated on both sides with a PE film and is commonly used for temporary storage of goods to protect against rain and dust.
[0003] Although the PE tarpaulins currently used for temporary covering of goods have certain moisture-proof properties when in use, they are relatively poor in waterproofness. As a result, when the PE tarpaulins are used to cover the goods, external rainwater can easily enter the goods, causing the goods to be eroded and damaged by external rainwater when stacked. At the same time, since the thermal insulation performance of the PE tarpaulins with the above structure is also relatively poor, the goods are also easily affected by the external ambient temperature when stacked, causing deformation and damage. In addition, when the PE tarpaulins with the above structure are used to cover relatively sharp objects, the PE tarpaulins with the above structure are easily damaged during use due to the poor wear resistance and puncture resistance of the PE tarpaulins themselves, resulting in a short service life of the PE tarpaulins. Utility Model Content
[0004] The technical problem to be solved by the present invention is to provide a thermal insulation and moisture-proof PE tarpaulin that can significantly increase the waterproof and thermal insulation performance of the PE tarpaulin, avoid the influence of external rain and external ambient temperature on the covering material, and significantly increase the wear resistance and puncture resistance.
[0005] The utility model is achieved through the following technical solution: the utility model proposes a heat-insulating and moisture-proof PE tarpaulin, comprising a base fabric layer, super-hydrophobic layers are distributed and installed on the upper and lower sides of the base fabric layer, a wear-resistant mesh is installed on the outer side of the super-hydrophobic layer, a heat-insulating layer is installed in the middle part of the base fabric layer, a lower reinforcing pad is installed on the lower side of the heat-insulating layer, an upper reinforcing pad is installed on the upper side of the heat-insulating layer, the bottom ends of the upper reinforcing pads are evenly provided with sockets, and an inserting platform is installed on the upper end of the lower reinforcing pad facing the sockets, and a PVC waterproof membrane is respectively installed between the base fabric layer and the upper reinforcing pad and the lower reinforcing pad.
[0006] By adopting the above technical solution, under the action of the super-hydrophobic layer, the PVC waterproof film and the thermal insulation layer, the waterproof and thermal insulation performance of the PE tarpaulin during use is significantly improved, which not only avoids the erosion of the stacked goods by external water vapor, but also avoids the influence of the external ambient temperature on the stacked goods, so that the storage quality of the goods covered by the PE tarpaulin is improved. At the same time, under the action of the wear-resistant mesh surface, the upper reinforcement pad and the lower reinforcement pad, the wear resistance and puncture resistance of the PE tarpaulin are improved, avoiding the disadvantage of the PE tarpaulin being easily scratched during use.
[0007] Furthermore, a connecting edge is installed on the periphery of the base fabric layer, and threading rings are evenly distributed on the connecting edge.
[0008] By adopting the above technical solution, the threading ring can cooperate with the external strap to achieve reliable binding and fixation at the edge of the PE tarpaulin.
[0009] Furthermore, the connecting edge and the base fabric layer are an integrated structure, and the base fabric layer is formed by interlaced weaving of PE flat yarns.
[0010] By adopting the above technical solution, the structural strength and protective performance of the PE tarpaulin can be effectively ensured.
[0011] Furthermore, the threading ring is a ring structure that is thin in the middle and thick at both ends, and the threading ring is plugged into the connecting edge.
[0012] By adopting the above technical solution, the threading ring can be reliably installed and fixed on the connecting edge.
[0013] Furthermore, the upper reinforcement pad and the lower reinforcement pad are both made of elastic rubber, and the socket matches the size of the socket.
[0014] By adopting the above technical solution, the puncture-proof performance of the PE tarpaulin can be significantly improved under the action of the upper reinforcement pad and the lower reinforcement pad.
[0015] Furthermore, the thermal insulation layer is bonded to the upper reinforcement pad and the lower reinforcement pad, and the thermal insulation layer is made of EPS foam material.
[0016] By adopting the above technical solution, the EPS foam has good thermal insulation performance, so that the influence of the external ambient temperature on the covered goods can be avoided under the action of the PE tarpaulin.
[0017] Furthermore, the PVC waterproof membrane is bonded to the super-hydrophobic layer, and the super-hydrophobic layer is a micro-nanopore Janus membrane.
[0018] By adopting the above technical solution, the straight-through channels of the hydrophilic layer of the micro-nanoporous Janus membrane have strong capillary force, and the water evaporation interface is pushed to the hydrophilic / hydrophobic interface inside the pore, thereby shortening the vapor transmission path to the maximum extent. Under the action of surface tension and wall effect, water presents a concave liquid surface in the pore, and the thin water layer formed near the wall has an effect similar to a "nano fireplace". Water molecules can obtain thermal energy more quickly and convert into a gaseous state at a faster rate, thereby promoting the evaporation process of water. Therefore, under the action of the super-hydrophobic layer, external water vapor can be effectively isolated, so that the moisture-proof performance of the PE tarpaulin is further improved.
[0019] Furthermore, the wear-resistant mesh surface is bonded to the super-hydrophobic layer, and the wear-resistant mesh surface is woven with polyester yarn.
[0020] By adopting the above technical solution, the polyester yarn has good wear resistance, thereby improving the wear resistance of the PE tarpaulin.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] The utility model installs a PCV waterproof membrane and a thermal insulation layer on the inner side of the base fabric layer, and installs a super-hydrophobic layer on the outer side of the base fabric layer, so that the waterproof and thermal insulation performance of the PE tarpaulin during use is significantly improved, which not only avoids the erosion of the stacked goods by external water vapor, but also avoids the influence of the external ambient temperature on the stacked goods, so that the storage quality of the goods covered by the PE tarpaulin is improved. At the same time, under the action of the wear-resistant mesh surface, the upper reinforcing pad and the lower reinforcing pad, the wear resistance and puncture resistance of the PE tarpaulin are improved, so that the disadvantage of the PE tarpaulin being easily scratched during use is avoided, and the service life of the PE tarpaulin is increased.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0031] like Figure 1-Figure 3 As shown, a heat-insulating and moisture-proof PE tarpaulin in this embodiment includes a base fabric layer 11, and super-hydrophobic layers 9 are distributed and installed on the upper and lower sides of the base fabric layer 11. The super-hydrophobic layer 9 adopts the double-sided film principle, which can reduce the adhesion of water on the surface of the base fabric layer 11 and increase the evaporation area of water, thereby improving the waterproof performance of the base fabric layer 11. A wear-resistant mesh surface 3 is installed on the outside of the super-hydrophobic layer 9. The wear-resistant mesh surface 3 can increase the wear resistance of the whole PE tarpaulin to a certain extent, and prevent the outside of the PE tarpaulin from being easily worn when in use. A thermal insulation layer 5 is installed in the middle of the base fabric layer 11. The design of the thermal insulation layer 5 ensures the thermal insulation performance of the whole PE tarpaulin, so that the PE tarpaulin can be effectively isolated from the external temperature when in use. A lower reinforcing pad 8 is installed on the lower side of the thermal insulation layer 5, and an upper reinforcing pad 4 is installed on the upper side of the thermal insulation layer 5. The ends are evenly distributed with sockets 6, and the upper end of the lower reinforcement pad 8 is installed with an insertion platform 7 opposite to the socket 6. PVC waterproof membranes 10 are respectively installed between the base fabric layer 11 and the upper reinforcement pad 4 and the lower reinforcement pad 8. The PVC waterproof membrane 10 utilizes the good waterproof performance of the PVC material to improve the overall waterproof performance of the PE tarpaulin. Under the action of the super-hydrophobic layer 9, the PVC waterproof membrane 10 and the thermal insulation layer 5, the waterproof and thermal insulation performance of the PE tarpaulin during use is significantly improved, which not only avoids the erosion of the stacked goods by external water vapor, but also avoids the influence of the external ambient temperature on the stacked goods, so that the storage quality of the goods covered by the PE tarpaulin is improved. At the same time, under the action of the wear-resistant mesh surface 3, the upper reinforcement pad 4 and the lower reinforcement pad 8, the wear resistance and puncture resistance of the PE tarpaulin are improved, avoiding the disadvantage of the PE tarpaulin being easily scratched during use.
[0032] like Figure 1 、 Figure 2 and Figure 4As shown, in this embodiment, a connecting edge 1 is further installed on the periphery of the base fabric layer 11, and threading rings 2 are evenly distributed on the connecting edge 1. The threading ring 2 can cooperate with the external strap to realize the reliable binding and fixation of the edge of the PE tarpaulin. This design can facilitate the flexible covering of goods of different heights by the PE tarpaulin when in use. The connecting edge 1 and the base fabric layer 11 are an integrated structure. The base fabric layer 11 is woven with PE flat wires, which can effectively ensure the structural strength and protective performance of the PE tarpaulin. The threading ring 2 is a ring structure that is thin in the middle and thick at both ends. The design of the threading ring 2 can effectively prevent the external strap from pulling and damaging the PE tarpaulin during use. The threading ring 2 is plugged into the connecting edge 1 to realize the reliable installation and fixation of the threading ring 2 on the connecting edge 1.
[0033] like Figure 2 、 Figure 3 and Figure 5 As shown, in this embodiment, the upper reinforcing pad 4 and the lower reinforcing pad 8 are both made of elastic rubber, and both the upper reinforcing pad 4 and the lower reinforcing pad 8 are thin sheet structures. Without significantly increasing the overall weight of the PE tarpaulin, the overall puncture resistance of the PE tarpaulin can be improved. The size of the insert sleeve 6 is matched with the insert platform 7. Under the action of the upper reinforcing pad 4 and the lower reinforcing pad 8, the puncture resistance of the PE tarpaulin can be significantly increased. The thermal insulation layer 5 is bonded to the upper reinforcing pad 4 and the lower reinforcing pad 8. The thermal insulation layer 5 is made of EPS foam material. EPS foam has good thermal insulation performance, so that it can avoid the influence of the external ambient temperature on the covered goods under the action of the PE tarpaulin.
[0034] like Figure 1-Figure 3As shown, in this embodiment, the PVC waterproof membrane 10 is bonded to the super-hydrophobic layer 9, and the super-hydrophobic layer 9 is a micro-nano-porous Janus membrane. The straight-through pores of the hydrophilic layer of the micro-nano-porous Janus membrane have a strong capillary force, and the water evaporation interface is pushed to the hydrophilic / hydrophobic interface in the pore, which shortens the vapor transmission path to the maximum extent. Under the action of surface tension and wall effect, water presents a concave liquid surface in the pore, and the thin water layer formed near the wall has an effect similar to a "nano-fireplace". Water molecules can obtain thermal energy faster and convert into a gaseous state at a faster rate, thereby promoting the evaporation process of water. Studies have shown that as the pore size of the micro-nano-porous Janus membrane decreases, the curvature of the concave liquid surface increases, and the proportion of the thin water layer increases, thereby enhancing the micro-scale heat transfer at the wall and promoting the evaporation of water. During the evaporation process, when water molecules change from liquid to gas, they need to absorb a certain amount of heat. This heat is called evaporation enthalpy. The magnitude of the evaporation enthalpy depends on the state transition of the water molecules involved. Energy changes include the internal energy of liquid water molecules, surface tension, and latent heat of water vapor. The pore walls of the Janus membrane's hydrophilic layer are rich in hydroxyl groups, which can bind to nearby water molecules, disrupting hydrogen bonds between the main water molecules and promoting the formation of intermediate water. This weakens the interaction between water molecules, reduces the heat required for evaporation, and significantly reduces the evaporation enthalpy (to only 30% of the evaporation of pure water). Furthermore, Janus membranes with small pores and low contact angles have more active sites for binding with water molecules, resulting in a lower evaporation enthalpy. Fluid dynamics simulations show that as the pore size decreases, the formation of microscale eddies is suppressed, inhibiting the back-mixing of intermediate water and promoting water evaporation. Therefore, the superhydrophobic layer 9 effectively isolates external water vapor, further improving the moisture-proof performance of the PE tarpaulin. The wear-resistant mesh 3 is bonded to the superhydrophobic layer 9 and is woven from polyester yarn, which has excellent wear resistance, thereby improving the wear resistance of the PE tarpaulin.
[0035] The specific implementation process of this embodiment is as follows: when in use, the PE tarpaulin only needs to be covered on the upper side of the stacked goods with the help of external straps, and the PED tarpaulin can be put into use. During use, under the action of the super-hydrophobic layer 9, the PVC waterproof membrane 10 and the thermal insulation layer 5, the waterproof and thermal insulation performance of the PE tarpaulin during use is significantly improved, which not only avoids the erosion of the stacked goods by external water vapor, but also avoids the influence of the external ambient temperature on the stacked goods, so that the storage quality of the goods covered by the PE tarpaulin is improved. At the same time, under the action of the wear-resistant mesh surface 3, the upper reinforcement pad 4 and the lower reinforcement pad 8, the wear resistance and puncture resistance of the PE tarpaulin are improved, avoiding the disadvantage of the PE tarpaulin being easily scratched during use, so that the service life of the PE tarpaulin is increased.
[0036] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
