Specific implementation mode

It is below in conjunction with the accompanying drawings and real in order to be more clearly understood that the above objects, features, and advantages of the utility model Example is applied to be described further the utility model.It should be noted that in the absence of conflict, embodiments herein and reality The feature applied in example can be combined with each other.

Many details are elaborated in the following description in order to fully understand the utility model, still, this practicality Novel to implement using different from other modes described here, therefore, the utility model is not limited to be described below The limitation of the specific embodiment of specification.

Embodiment 1, as shown in Figure 1, Figure 2, Figure 3 shows, the utility model aim to solve the problem that existing PVC hose stretch-proof and shock resistance The problem of intensity, for this purpose, the present embodiment provides provide a kind of novel PVC hose, the novel PVC hose package that the present embodiment is provided Include the isolation internal layer 1 set gradually from inside to outside, PVC plastic internal layer 2, braiding internal layer 3, layer of polyurethane 4, woven outer layer 5, PVC Plastic outer layer 6 and isolation outer layer 7, wherein the material of isolation internal layer 1 and isolation outer layer 7 is fluororesin, in the present embodiment, The thickness that internal layer 1 and isolation outer layer 7 is isolated is smaller, is similar to one layer of thin coating, using fluororesin as inner surface and outer Surface is primarily due to fluororesin with excellent high and low temperature resistance, dielectric properties, chemical stability, weatherability, non-ignitable The characteristics such as property, non-stick and low friction coefficient form certain isolation in this way, using its excellent performance, avoid tradition The technical issues of high temperature bonding of PVC hose, black brittleness are easily destroyed, in addition, making to preferably be matched with PVC plastic With fluororesin used in the present embodiment is polytetrafluoroethylene (PTFE).

Braiding internal layer 3 and woven outer layer 5 include the web 31/51 in criss-cross weave diamondwise aperture, wherein compile The material for knitting the web 31 of internal layer 3 is terylene, and terylene is an important kind in synthetic fibers, is China's polyester fiber Trade name.Be with p-phthalic acid (PTA) or dimethyl terephthalate (DMT) (DMT) and ethylene glycol (EG) it is raw material through esterification Or prepared by transesterification and polycondensation reaction fiber-forming polymer -- polyethylene terephthalate (PET), through spinning with after Fiber made of reason.Terylene has many advantages, such as that intensity is high, elasticity is good, is disposed in hose, is conducive to improve tensile strength.

Woven outer layer 5 further includes the connection fiber 52 being arranged along hose axis, and connects fiber 52 and be arranged in web 51 On, tool is said, is provided with four connection fibers 52 altogether in woven outer layer 5, angle is 90 degree between connecting fiber 52, in this implementation In example, in order to improve tensile strength again, in the present embodiment, connection fiber 52 and the tie point of web 51 are not at web The point of intersection of 51 diamond shape through-holes, such setting are conducive to further increase intensity.In the present embodiment, the fibre of woven outer layer 5 It is polyamide fibre to tie up net 51 and connect the material of fiber 52, and polyamide fibre is also known as nylon, in the present embodiment, using polyamide fibre as woven outer layer Material mainly utilize its anti-flammability other than the advantage high using its intensity, elasticity is good because once hose occurs Therefore fire, is acted on woven outer layer typically since outside, equally, in order to further increase tensile strength,.

In order to further improve tensile resistance and impact strength, the present embodiment traditional PVC plastic bed of material it Between also added layer of polyurethane 4, the material of layer of polyurethane 4 is polyurethane, and polyurethane resin 4 having high intensity, anti-as a kind of Tearing, the characteristics such as wear-resisting high molecular material, there is excellent gumminess simultaneously, PVC plastic internal layer 2 can be made, in braiding Layer 3, woven outer layer 5 and PVC plastic outer layer 6 form globality structure, and then improve its performance.
