Abstract

The invention relates to a PP double-walled corrugated pipe. The corrugated pipe comprises an outer wall pipe and an inner wall pipe, and is integrally formed through a double-cone double-screw extruder; the outer wall pipe is prepared from the following raw materials in parts by weight: 50-60 parts of polypropylene resin, 4-7 parts of reclaimed materials, 20-40 parts of a fixed filler, 4-5 parts of stearic acid, 3-5 parts of a drying agent, 2-5 parts of a dyeing agent, and 5-10 parts of talcum powder; the inner wall pipe is prepared from the following raw materials in parts by weight: 45-65 parts of polypropylene resin, 4-7 parts of reclaimed materials, 20-40 parts of a fixed filler, 4-5 parts of stearic acid, 3-5 parts of a drying agent, 2-5 parts of a dyeing agent, and 5-10 parts of talcum powder. The inner pipe material and the outer pipe material of the double-walled corrugated pipe prepared from the ingredients are high in melt strength and rigidity, so that the double-walled corrugated pipe is higher in rigidity, better in pressure resistance and lighter in weight of pipe materials; polypropylene resin raw materials are adopted in the constituent materials of the outer pipe, so that the ring flexibility of the outer pipe is improved, and the toughness is better.

Description

A kind of PP double-wall corrugated pipe
Technical field
The present invention relates to a kind of double-wall corrugated pipe.
Background technology
A kind of novel light tubing that double-wall corrugated pipe is is raw material with high density polyethylene (HDPE), has the features such as lightweight, high pressure resistant, good toughness, fast, the life-span length of construction, and the structural pipe wall design of its excellence, compared with the tubing of other structures, cost is substantially reduced.And due to easy to connect, reliable, at home and abroad it is used widely.A large amount of pipe of concretes and cast iron pipes of substituting, but the accident such as the ring stiffness with regard to existing double-wall corrugated pipe product does not reach standard-required, causes engineering to do over again, schedule delays, serious wastes social resources.Therefore find out and a kind of produce saving, colory double-wall corrugated pipe formula has become the trend of a kind of necessity.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of ring stiffness, ring are flexible, the PP double-wall corrugated pipe that lightweight, intensity is high.
In order to solve above-mentioned technical problem, the invention provides a kind of PP double-wall corrugated pipe, described corrugated tube includes outer wall pipe and inner wall tube, and described corrugated tube is one-body molded by bipyramid double screw extruder, being made up of the raw material of following weight parts of described outer wall pipe: acrylic resin: 50～60 parts, reworked material: 4～7, fixing inserts: 20～40 parts, stearic acid: 4～5 parts, desiccant: 3～5 parts, stain: 2～5 parts, Pulvis Talci: 5～10 parts；Being made up of the raw material of following weight parts of described inner wall tube: acrylic resin: 45～65 parts, reworked material: 4～7, fixing inserts: 20～40 parts, stearic acid: 4～5 parts, desiccant: 3～5 parts, stain: 2～5 parts, Pulvis Talci: 5～10 parts;The melt index MFR at the temperature of 0～230 DEG C of the acrylic resin of described outer wall pipe is: 0.3-0.4g/10min；The acrylic resin of described inner wall tube melt index at the temperature of 0～230 DEG C is: 0.8-1.0g/10min.
Stain in described outer wall pipe raw material adopts black masterbatch.
Stain in described inner wall tube raw material adopts blue masterbatch.
Described fixing inserts is calcium powder, and described calcium powder is 1000-1250 order.
Compared with prior art, the present invention has the advantage that
PP double-wall corrugated pipe provided by the invention, adopt double-wall corrugated pipe that this dispensing makes inside and outside it tubing there is higher melt strength and rigidity, have both good shock resistance simultaneously, make that double-wall corrugated pipe ring stiffness is higher, crushing resistance better, tubing weight is lighter, and the composition material of outer tube adopts acrylic resin raw material, the ring flexibility making outer tube increases, toughness better, can be widely used for without the buried draining of compression molding material, blow-off line.
Described corrugated tube is one-body molded by bipyramid double screw extruder, and it is energy-conservation, and plasticizing effect is good so that produce double-wall pipe tubing uniform, and stable yield can improve pipe finished quality, and yield rate is high, tubing intensity enhancing, and production efficiency is high.
