Abstract

The invention relates to the field of plastic pipes, and discloses a heat-preservation plastic pipeline. The wall of the heat-preservation plastic pipeline comprises an outer fiber layer, an outer polyethylene fiber layer, a foamed plastic layer and an inner polyethylene fiber layer from outside to inside in sequence, wherein the outer fiber layer is made of carbon fiber or aramid fiber or glass fiber. According to the heat-preservation plastic pipeline, a four-layer composite structure is adopted, the foamed plastic layer is arranged between the inner polyethylene fiber layer and the outer polyethylene fiber layer, and therefore thermal insulation properties of the pipeline are improved; the outer fiber layer is arranged outside the outer polyethylene fiber layer, so that the pipeline is prevented from fractures or frost cracks, and the pipeline can be adapted to temperature changes; the outer fiber layer, the inner polyethylene fiber layer and the outer polyethylene fiber layer are respectively of a longitudinally and transversely staggered net structure, and therefore bearing capacity can be improved.

As preferably, fibrous outer is the staggered reticular structure of long grain fiber and traverse fiber, between adjacent long grain fiber, is spaced apart 50um-100um, between adjacent transverse fiber, is spaced apart 50um-100um.Adopt mesh structure, increase bearing capacity, between adjacent long grain fiber, be spaced apart 50um-100um, between adjacent transverse fiber, be spaced apart 50um-100um, between the reticulated work of formation, space is little like this, and bearing capacity is large.
As preferably, polyvinyl fiber skin is the staggered reticular structure of long grain fiber and traverse fiber, between adjacent long grain fiber, is spaced apart 50um-100um, between adjacent transverse fiber, is spaced apart 50um-100um.Adopt mesh structure, increase bearing capacity, between adjacent long grain fiber, be spaced apart 50um-100um, between adjacent transverse fiber, be spaced apart 50um-100um, between the reticulated work of formation, space is little like this, and bearing capacity is large.
As preferably, polyvinyl fiber internal layer is the staggered reticular structure of long grain fiber and traverse fiber, between adjacent long grain fiber, is spaced apart 50um-100um, between adjacent transverse fiber, is spaced apart 50um-100um.Adopt mesh structure, increase bearing capacity, between adjacent long grain fiber, be spaced apart 50um-100um, between adjacent transverse fiber, be spaced apart 50um-100um, between the reticulated work of formation, space is little like this, and bearing capacity is large.
As preferably, foam layer is phenolic foam.Phenolic foam thermal insulation property is fine.
The present invention, owing to having adopted above technological scheme, has significant technique effect:
The present invention adopts four layers of composite structure, between polyvinyl fiber internal layer and polyvinyl fiber skin, be provided with one deck foam layer, improved the thermal insulation property of pipeline, at polyvinyl fiber skin, be provided with fibrous outer, prevent fracture or bursting by freezing, variation that can adaptive temperature, fibrous outer and polyvinyl fiber internal layer and polyvinyl fiber skin all adopt the reticular structure of fir traversed by mistake, can increase bearing capacity.
