Abstract

The invention provides a non-excavating enhanced and modified polypropylene draining pipe. The pipe consists of the basic materials of, by weight, 100 parts of PPB resin, 30-40 parts of PPH resin, 0-0.8 parts of an antioxidant, 0-0.6 parts of a processing agent, 0-1 parts of an ultraviolet stabilizer. The pipe has the advantages of good toughness and high tensile strength, is helpful for non-excavating constructions of the underground draining pipelines, and improves the use security of the pipelines.

Description

Non-excavation enhancing modified Vestolen PP 7052 draining blow-off pipe
Technical field
The present invention relates to a kind of plastic conduit, particularly a kind of non-excavation enhancing modified Vestolen PP 7052 draining blow-off pipe.
Background technology
Progress and development of city along with science and technology; Various pipelines have been given play to increasing effect in urban construction; Particularly plastic lined piping is used in the city because of its well-known advantage that has is progressively replacing conventional line, and along with the rise of no-excavation construction method, plastic lined piping becomes the new lover of non-excavating construction with its excellent flexibility; And the tensile strength of polypropylene pipe is lower, need improve tensile property.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned technology, propose a kind of good toughness, non-excavation enhancing modified Vestolen PP 7052 draining blow-off pipe that tensile strength is high.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is such.This non-excavation enhancing modified Vestolen PP 7052 draining blow-off pipe is made up of 100 parts of PPB resins, 30~40 parts of PPH resins, 0~0.8 part in oxidation inhibitor, 0~0.6 part of processing aid, 0~1 part of UV light stabilizing agent the basic material of weight part.
Wherein said oxidation inhibitor is 2,4, the 6-tri-butyl-phenol.
Wherein said UV light stabilizing agent is UV284, i.e. 2-hydroxyl-4-methoxyl group 5 diphenylsulfone ketones.
Wherein said processing aid can be this area processing aid commonly used, and the example of the processing aid of suitable indefiniteness has dispersion agent (like OPE) etc.
By metering raw material being added forcing machine during production, is the non-excavation enhancing modified of the present invention Vestolen PP 7052 draining blow-off pipe through extruder for shaping.
Advantage of the present invention is: tubing good toughness, tensile strength are high, help the non-excavating construction of underdrainage blowdown pipeline, improve the safety in utilization of pipeline.
Specific embodiments
Non-each basic weight of material part of excavation enhancing modified Vestolen PP 7052 draining blow-off pipe is: 100 parts of PPB resins, 40 parts of PPH resins, 0.6 part in oxidation inhibitor, 0.3 part of processing aid, 1 part of UV light stabilizing agent.
Its production technique is following: by metering raw material being added forcing machine, is the non-excavation enhancing modified of the present invention Vestolen PP 7052 draining blow-off pipe through extruder for shaping.
This non-excavation enhancing modified Vestolen PP 7052 draining blow-off pipe physical and mechanical properties is following:
The coefficient of sliding friction 0.23~0.28 tensile strength (23 ℃ ± 2 ℃) 24.5~29.7MPa, flexural strength (23 ℃ ± 2 ℃) 35.2~37.6MPa.
