Description

Technical Field

[0001] The utility model relates to a garden hose, in particular to a foamed PVC garden hose. Background Art

[0002] At present, garden hoses are mainly directly extruded and formed from ordinary PVC materials. Therefore, from the cross-section, the wall structure is a single-layer wall. In order to safely withstand water pressure and ensure the use quality of the garden hose with this single-layer wall structure, the wall thickness is often designed to be relatively large, which not only increases the production cost of materials, but also increases the overall weight and transportation cost. At the same time, the garden hose with a single-layer wall design is also easily affected by low-temperature environments and suffers from fatigue aging damage of the material, so its low-temperature resistance is poor, greatly affecting the service life and being not conducive to green environmental protection and saving social resources. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a foamed PVC garden hose that can reduce the weight of the hose, lower the material cost and transportation cost, and enhance the low-temperature resistance.

[0004] The technical problem of the utility model is realized through the following technical solutions:

[0005] A foamed PVC garden hose has a multi-layer composite integrated wall, and the multi-layer composite integrated wall is composed of a general-purpose PVC soft glue inner layer, a foamed PVC soft glue inner layer, a composite fiber layer, a foamed PVC soft glue outer layer, and a general-purpose PVC soft glue outer layer that are sequentially wrapped from the inside out.

[0006] The thickness of the general-purpose PVC soft glue inner layer accounts for 5%-50% of the overall thickness of the wall.

[0007] The thickness of the foamed PVC soft glue inner layer accounts for 5%-50% of the overall thickness of the wall.

[0008] The thickness of the foamed PVC soft glue outer layer accounts for 5%-40% of the overall thickness of the wall.

[0009] The thickness of the general-purpose PVC soft glue outer layer accounts for 5%-40% of the overall thickness of the wall.

[0010] The composite fiber layer is woven by winding yarns in a mesh pattern, and the composite fiber layer is made of polyester material or nylon material or aramid material.

[0011] The general-purpose PVC soft glue inner layer and the foamed PVC soft glue inner layer are compounded into one to form the inner layer of the wall.

[0012] The foamed PVC soft glue outer layer and the general-purpose PVC soft glue outer layer are compounded into one to form the outer layer of the wall.

[0013] Compared with the prior art, the utility model mainly designs a foamed PVC garden hose with a multi-layer composite integral pipe wall. The multi-layer composite integral pipe wall is composed of a general PVC soft glue inner layer, a foamed PVC soft glue inner layer, a composite fiber layer, a foamed PVC soft glue outer layer, and a general PVC soft glue outer layer wrapped in sequence from the inside to the outside. Compared with the traditional single-layer pipe wall, it has the advantages of reducing the weight of the hose, lowering the material cost and transportation cost, and enhancing the low-temperature resistance performance, etc., so it is beneficial to environmental protection and saving social resources.

[0018] Next, the embodiments of the utility model will be further described in detail with reference to the above drawings.

[0019] As Figures 1 to 4 shown, 1. Inner pipe wall, 11. General PVC soft glue inner layer, 12. Foamed PVC soft glue inner layer, 2. Composite fiber layer, 3. Outer pipe wall, 31. Foamed PVC soft glue outer layer, 32. General PVC soft glue outer layer.

[0020] A foamed PVC garden hose mainly relates to a water pipe for garden greening irrigation; wherein, the foamed PVC garden hose has a multi-layer composite integral pipe wall as shown in Figure 1 , Figure 2 shown. The multi-layer composite integral pipe wall is composed of a general PVC soft glue inner layer 11, a foamed PVC soft glue inner layer 12, a composite fiber layer 2, a foamed PVC soft glue outer layer 31, and a general PVC soft glue outer layer 32 wrapped in sequence from the inside to the outside.

[0021] Moreover, the general PVC soft glue inner layer 11 and the foamed PVC soft glue inner layer 12 are integrally combined to form the inner pipe wall 1; the foamed PVC soft glue outer layer 31 and the general PVC soft glue outer layer 32 are integrally combined to form the outer pipe wall 3.

[0022] The thickness of the general PVC soft glue inner layer 11 accounts for 5%-50% of the overall wall thickness; the thickness of the foamed PVC soft glue inner layer 12 accounts for 5%-50% of the overall wall thickness; the thickness of the foamed PVC soft glue outer layer 31 accounts for 5%-40% of the overall wall thickness; the thickness of the general PVC soft glue outer layer 32 accounts for 5%-40% of the overall wall thickness.

[0023] The composite fiber layer 2 is usually woven by winding yarns in a mesh pattern, such as Figure 3 , Figure 4 shown in these two weaving methods; of course, in actual manufacturing, it includes but is not limited to these two methods; at the same time, the materials selected for the composite fiber layer 2 include but are not limited to polyester, nylon, aramid, etc.
