Description

PVC pipe formed by extrusion of soft and hard materials

Technical Field

The utility model belongs to the pipeline field, in particular to PVC pipe of soft or hard material extrusion.

Background

At present, two types of PVC pipes are mainly used in the market, one type is a PVC hose, and the other type is a PVC hard pipe, and the PVC pipes are generally applied to different occasions according to the performance requirements. The hardness of the PVC hose is generally 0-70 ℃, the PVC hose has good toughness and bending property, but the PVC hose has poor rigidity and is easy to deform; the rigid PVC pipe has good rigidity and strong deformation resistance, but the toughness and the bending property are poor, so that the use flexibility of the rigid PVC pipe is limited. Therefore, at present, the two pipelines cannot have toughness and rigidity, and the use is greatly limited. In order to solve the problems, at present, a PVC steel wire pipe is provided, wherein steel wires are embedded in a PVC hose, the PVC hose has the toughness of the hose, the rigidity of the pipe can be improved, and the deformation resistance of the pipe can be improved.

Detailed Description

To facilitate understanding of those skilled in the art, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, 2 and 3, a PVC pipe of soft or hard material extrusion, including inlayer body 2 and outer body 1, inlayer body 2 and outer body 1 are the soft material of PVC, and the embedding has spiral heliciform spirochaeta 3 between inlayer body 2 and the outer body 1, and spirochaeta 3 is the modified hard material of PVC, and inlayer body 2, outer body 1 and spirochaeta 3 extrusion are as an organic whole. The production can be carried out by the following steps: firstly, stirring and preparing PVC soft materials for the use of the inner-layer pipe body 2 and the outer-layer pipe body 1; secondly, stirring the PVC hard material for the spiral body 3; and step three, putting the PVC soft material and the PVC hard material into an extruder, and extruding the inner layer pipe body 2, the outer layer pipe body 1 and the spiral body 3 by the extruder through a die to be integrally formed. Inner tube body 2 and outer body 1 are the soft material of PVC, have the characteristics that toughness is good, bending property is good, and spirochaeta 3 has the rigidity supporting effect for the modified hard material of PVC for the PVC pipe has had toughness and rigidity concurrently, and does not use the steel wire, does not fear sour, alkaline environment, makes this PVC pipe can the wide application, can regard as the pipe that uses of engineering pipe, high temperature resistant pipe, bathroom water pipe, bathroom accessory pipe.

Further, the outer surface of the spiral body 3 is provided with ribs 31, and the ribs 31 are distributed on the surface of the spiral body 3. The ribs 31 are provided in a plurality, each rib 31 extending axially along the spiral body 3. Because what spirochaeta 3 and inlayer body 2 and outer body 1 adopted is different materials, the setting of burr 31 can make spirochaeta 3 and inlayer body 2 and outer body 1's combination more inseparable, promotes structural strength for the stability of PVC pipe is higher.

Further, the cross section of the spiral body 3 is circular, elliptical, triangular or square. The spiral bodies 3 with different cross sections are adopted, the structural strength is different, and the spiral bodies 3 with different cross sections can be adopted according to the requirement.

Further, the hardness of the inner layer tube body 2 and the outer layer tube body 1 is 50-60 degrees in Rockwell hardness, and the hardness of the spiral body 3 is 110-125 degrees in Rockwell hardness. Through optimization selection, the hardness selection enables the toughness and rigidity of the whole PVC pipe to be optimized.

Furthermore, the pipe diameter of the PVC pipe is 8-100mm, and the pipe wall thickness is 1.5-6 mm. The two ends of the PVC pipe are flat and straight openings. The PVC pipe with the specifications can exert the performance to a better level.

The above embodiments are preferred implementations of the present invention, and are not intended to be limiting, and any obvious replacement is within the scope of the present invention without departing from the inventive concept of the present invention.
