Description

Technical Field

[0001] The utility model relates to the technical field of plastic materials, in particular to a waterproof and weather-resistant plastic. Background Art

[0002] Cables are important carriers of modern information and power transmission. The material and performance of their protective covers directly determine the transmission efficiency, service life and safety of cables. Traditional cable protective covers are mainly made of plastic, rubber, etc. However, in special environments, such as humid environments, outdoor environments or ultraviolet radiation environments, these traditional materials will degrade in performance due to water absorption, ultraviolet radiation and weather aging, which will damage the protective effect of the cables, reduce their service life, and may even cause fires or power accidents. This requires the development of a new type of plastic material with excellent waterproof, weather-resistant and anti-ultraviolet aging properties.

[0003] In the past few decades, although there have been many efforts to improve the waterproofness, aging resistance and weather resistance of cable protective sheaths by improving manufacturing processes and adding special additives, the ideal effect has not been achieved. In fact, the performance decay and aging rate of current cable protective sheaths are quite fast when exposed to moisture, high-intensity ultraviolet rays or weathering environments, which cannot meet the needs of modern power and communication industries.

[0004] On the one hand, the waterproof performance of the cable sheath is crucial to the safety and durability of the cable. If the cable sheath is not effectively waterproof, rain or moisture will penetrate into the cable, causing the cable insulation to deteriorate, which may cause the cable to short-circuit in the long run, causing serious safety problems. On the other hand, the cable sheath needs to have good UV and weather resistance. Ultraviolet rays and weather aging are the main causes of cable sheath degradation and cracking. Since cables generally need to be used in outdoor environments, the weather resistance and UV resistance of the cable sheath material are very high. If the cable sheath cannot effectively resist weather aging and UV radiation, the life of the sheath will be greatly shortened and the protection effect of the cable will be greatly reduced.

[0005] In view of this, it is indeed necessary to develop a new type of plastic for cable protective sheath, which has both excellent waterproof performance and good UV aging resistance and weather resistance. Utility Model Content

[0006] The purpose of the utility model is to provide a plastic with excellent waterproof performance, good ultraviolet aging resistance and weather resistance in view of the shortcomings of the prior art.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A waterproof and weather-resistant plastic, used for cable protective sheath, comprising:

[0009] PU plastic base layer;

[0010] An aramid fiber layer is disposed on the upper surface of the PU plastic base layer;

[0011] An aluminum-plastic film layer is arranged on the upper surface of the aramid fiber layer;

[0012] A silver halide particle layer is arranged on the outer surface of the aluminum-plastic film layer;

[0013] Wherein, a plurality of reinforcing protrusions are evenly distributed on the outer surface of the silver halide particle layer, and the tensile strength of the plastic is 180-200 MPa.

[0014] In one embodiment of the waterproof and weather-resistant plastic according to the present application, a fluorocarbon wax layer is further provided between the aluminum-plastic film layer and the silver halide particle layer.

[0015] In one embodiment of the waterproof and weather-resistant plastic according to the present application, a carbon fiber layer is further provided between the PU plastic matrix layer and the aramid fiber layer.

[0016] In one embodiment of the waterproof and weather-resistant plastic according to the present application, a graphene heat-conducting layer is further provided between the PU plastic base layer and the aramid fiber layer.

[0018] In one embodiment of the waterproof and weather-resistant plastic described in the present application, each layer is formed into an integrated structure by thermal compression bonding or magnetron sputtering.

[0019] In one embodiment of the waterproof and weather-resistant plastic according to the present application, the overall thickness of the plastic is 1 to 10 mm.

[0020] The beneficial effects of the utility model are as follows: the utility model is a waterproof and weather-resistant plastic, which is applied to a cable protective cover, comprising: a PU plastic matrix layer; an aramid fiber layer, which is arranged on the upper surface of the PU plastic matrix layer; an aluminum-plastic film layer, which is arranged on the upper surface of the aramid fiber layer; and a silver halide particle layer, which is arranged on the outer surface of the aluminum-plastic film layer; wherein a plurality of reinforcing protrusions are evenly distributed on the outer surface of the silver halide particle layer, and the tensile strength of the plastic is 180-200 MPa. Compared with the prior art, the utility model adopts PU as the plastic substrate layer. PU is a material with good waterproofness and good elasticity, and has very good aging resistance and excellent weather resistance, which can ensure the overall stability of the plastic; by setting the aramid fiber layer, the plastic can have excellent acid and alkali resistance and tear resistance, thereby improving the durability and reliability of the plastic; by setting the aluminum-plastic film layer, the plastic can be guaranteed to have excellent water-proof performance, which can effectively prevent external moisture from penetrating into the cable; by setting the silver halide particle layer, the silver halide particles are decomposed into silver and halogen under sunlight, thereby absorbing ultraviolet rays, improving the ultraviolet resistance of the plastic, effectively preventing the aging of the plastic, and improving its weather resistance; in addition, a number of reinforcing protrusions are evenly distributed on the outer surface of the silver halide particle layer, which can provide additional support when stretched, further improving the tensile strength of the plastic, ensuring that it is within the range of 180 to 200 MPa, and meeting high-intensity use requirements.

[0026] In order to make the technical solution and advantages of the utility model clearer, the utility model and its beneficial effects will be further described in detail below in combination with specific implementation methods and drawings of the specification, but the implementation methods of the utility model are not limited thereto.

[0027] Example 1

[0028] like Figure 1 As shown, the waterproof and weather-resistant plastic provided in this embodiment is applied to a cable protective cover, comprising: a PU plastic base layer 1;

[0029] Aramid fiber layer 2, arranged on the upper surface of the PU plastic base layer 1;

[0030] An aluminum-plastic film layer 3 is arranged on the upper surface of the aramid fiber layer 2;

[0031] A silver halide particle layer 4 is arranged on the outer surface of the aluminum-plastic film layer 3;

[0032] There are a number of reinforcement protrusions 41 evenly distributed on the outer surface of the silver halide particle layer 4, and the tensile strength of the plastic is 180-200 MPa, preferably 200 MPa.

[0033] In this embodiment, the layers are bonded together by heat pressing or magnetron sputtering to form an integrated structure. This ensures that the layers of plastic material are tightly bonded, avoids the possibility of interlayer peeling, and improves the mechanical strength and durability of the plastic as a whole. Among them, the heat pressing and magnetron sputtering methods belong to the prior art in this field and will not be described in detail here.

[0034] In this embodiment, the overall thickness of the plastic is 1-10 mm, for example, 1 mm, 3 mm, 5 mm, 8 mm or 10 mm; the specific thickness of the plastic can be adjusted as needed.

[0035] Among them, the utility model provides a waterproof and weather-resistant plastic for cable protective sheaths, which adopts a multi-layer structure design, and each layer brings unique protection characteristics to the cable protective sheath, ensuring the long-term stability and reliability of the cable. Specifically, the advantages of the utility model include but are not limited to the following points:

[0036] 1) Excellent waterproof and weather resistance: PU plastic is used as the base material, which has excellent waterproofness and good elasticity, and also exhibits excellent aging resistance and weather resistance. This design choice ensures the overall stability of the plastic, and its performance can be maintained even in harsh external environments.

[0037] 2) Enhanced durability and reliability: By introducing the aramid fiber layer, the plastic of the utility model not only greatly improves the acid and alkali resistance and tear resistance, but also enhances the overall structural strength of the plastic. The addition of aramid fiber provides an additional protective layer for the cable protective cover, enhancing its ability to resist external physical damage.

[0038] 3) Excellent water-proof performance: The aluminum-plastic film layer placed on the aramid fiber layer provides a solid waterproof barrier for the cable protective cover. This layer can not only effectively prevent water penetration, but also protect the internal cable from moisture and water intrusion, ensuring the performance and safety of the cable.

[0039] 4) Highly effective UV resistance: The silver halide particle layer, especially its ability to decompose into silver and halogen under sunlight, provides the plastic with strong UV resistance. This not only extends the service life of the cable protective cover, but also effectively avoids material aging and performance degradation that may be caused by long-term UV exposure.

[0040] 5) Improved tensile strength: Several enhanced protrusions are evenly distributed on the outer surface of the silver halide particle layer. These designs can provide additional support when the plastic is stretched, thereby significantly improving the tensile strength of the plastic. This feature ensures that the plastic can still maintain its integrity and functionality when facing high-strength stretching or stress, meeting high-standard usage requirements.

[0041] In summary, the utility model achieves all-round protection for the cable protective cover through an innovative multi-layer structure design, especially in terms of waterproofness, weather resistance, durability and tensile strength compared with the existing technology.

[0042] Example 2

[0043] like Figure 2 As shown, different from Example 1, a fluorocarbon wax layer 5 is further provided between the aluminum-plastic film layer 3 and the silver halide particle layer 4 in this embodiment. By further providing a super-hydrophobic fluorocarbon wax layer 5, the waterproof performance of the entire plastic can be further improved.

[0044] The other structures are the same as those in Example 1 and will not be described in detail here.

[0045] Example 3

[0046] like Figure 3 As shown, different from Example 1, a carbon fiber layer 6 is further provided between the PU plastic matrix layer 1 and the aramid fiber layer 2 in this embodiment. By further providing the carbon fiber layer 6, the tear strength of the plastic can be further improved, and the service life of the plastic can be increased.

[0047] The other structures are the same as those in Example 1 and will not be described in detail here.

[0048] Example 4

[0049] like Figure 4As shown, unlike Example 1, a graphene thermal conductive layer 7 is further provided between the PU plastic matrix layer 1 and the aramid fiber layer 2 in this embodiment; by providing the graphene thermal conductive layer 7, the heat inside the cable can be quickly transferred to the external environment, thereby improving the thermal conductivity of the cable. Among them, the thermal conductivity of the graphene thermal conductive layer 7 in this embodiment is 2000-2500 W / m·K. The thermal conductivity of commonly used thermal conductive materials such as copper is about 400 W / m·K, while the thermal conductivity of silver is about 430 W / m·K. Therefore, the thermal conductivity of the graphene used in this application is significantly better than these traditional metal thermal conductive materials.

[0050] The other structures are the same as those in Example 1 and will not be described in detail here.

[0051] Example 5

[0052] like Figure 1 As shown, different from Example 1, the upper surface of the PU plastic matrix layer 1 of this embodiment is provided with a plurality of first protrusions and a plurality of second protrusions, the first protrusions and the second protrusions are spaced and alternately arranged, and the height ratio of the first protrusions to the second protrusions is 1.5: 1. By providing the first protrusions and the second protrusions of different heights and controlling the appropriate height ratio, the contact area between the PU plastic matrix layer 1 and the adjacent layers can be effectively increased, and the connection strength between the layers can be improved.
