Abstract

The invention discloses a PP corrugated pipe modified by ethylene propylene rubber (EPR). The PP corrugated pipe modified by the ethylene propylene rubber (EPR) comprises an outer wall pipe body and an inner wall pipe body, and the outer wall pipe body is composed of, by mass, 40-60 parts of polypropylene resin, 20-30 parts of nano calcium carbonate, 10-15 parts of ethylene propylene rubber (EPR) compound modifier, 1-3 parts of a colouring agent and 1-3 parts of a defoaming agent; the inner wall pipe body is composed of, by mass, 40-60 parts of polypropylene resin, 20-30 parts of nano calcium carbonate, 10-15 parts of ethylene propylene rubber (EPR) compound modifier, 1-3 parts of the colouring agent and 1-3 parts of the defoaming agent. By means of the PP corrugated pipe modified by the ethylene propylene rubber (EPR), low-temperature brittleness of the PP corrugated pipe can be lowered, toughness of an FRPP corrugated pipe in a low-temperature environment is improved, and non-notched impact strength, elongation at break and melt flowability of the PP corrugated pipe are all remarkably improved.

Description

EP rubbers EPR Modified PP Corrugated tube
Technical field
The present invention relates to a kind of Bellows Technology field, particularly relate to the modified PP corrugated tube of a kind of EP rubbers EPR.
Background technology
PP corrugated pipe is a kind of novel light tubing with high density polyethylene (HDPE) as raw material, 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 replacement pipe of concretes and cast iron pipe, but the ring stiffness with regard to existing PP corrugated pipe product does not reaches standard-required, engineering is caused to do over again, the accidents such as schedule delays, serious wastes social resources, and the unnotched impact strength of PP corrugated tube, elongation at break, hot strength and melt flowability are not the most fine.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that the PP corrugated tube that a kind of EP rubbers EPR is modified.It solves technical problem and be the technical scheme is that the modified PP corrugated tube of a kind of EP rubbers EPR, and PP corrugated tube modified for described EP rubbers EPR includes that outer wall pipe and inner wall tube, described outer wall pipe are made up of by quality proportioning following raw material:
Acrylic resin: 40～60 parts, nano-calcium carbonate: 20～30 parts, EP rubbers EPR composite modifier: 10～15 parts, stain: 1～3 part, defoamer: 1～3 part；
Described inner wall tube is made up of by quality proportioning following raw material:
Acrylic resin: 40～60 parts, nano-calcium carbonate: 20～30 parts, EP rubbers EPR composite modifier: 10～15 parts, stain: 1～3 part, defoamer: 1～3 part；
The acrylic resin of described outer wall pipe melt index MFR at a temperature of 0～65 DEG C is: 0.1-0.3 g/10min；The acrylic resin of described inner wall tube melt index at a temperature of 0～65 DEG C is: 0.5-0.9 g/10min；Then stir processing extrusion molding with mixer.
It is also preferred that the left the stain in described outer wall pipe raw material uses black masterbatch.
It is also preferred that the left the stain in described inner wall tube raw material uses blue masterbatch.
It is also preferred that the left described nano-calcium carbonate particle diameter is 50～95nm.
The invention has the beneficial effects as follows, use the PP corrugated tube modified for EP rubbers EPR that this dispensing is made, can effectively reduce PP corrugated tube black brittleness, significantly improve FRPP corrugated tube toughness at low ambient temperatures, its unnotched impact strength, elongation at break, hot strength, melt flowability is all significantly increased；The composition material of outer wall pipe uses acrylic resin so that the ring flexibility of outer wall pipe increases, toughness is more preferable, can be widely used for without the buried draining of compression molding material, blow-off line；Using mixer to stir processing extrusion molding, plasticizing effect is good, can improve pipe finished quality, and yield rate is high, tubing intensity enhancing, and production efficiency is high；Inside and outside wall tubing has higher melt strength and rigidity, has both good shock resistance simultaneously so that PP corrugated pipe ring rigidity modified for EP rubbers EPR is higher, crushing resistance more preferable, tubing weight is lighter；Cheap, be suitable to industrial mass production and use, there is considerable economic worth.
Detailed description of the invention
The present invention is described in further details by detailed description below.
The PP corrugated tube that a kind of EP rubbers EPR is modified, PP corrugated tube modified for described EP rubbers EPR includes that outer wall pipe and inner wall tube, described outer wall pipe are made up of by quality proportioning following raw material:
Acrylic resin: 40～60 parts, nano-calcium carbonate: 20～30 parts, EP rubbers EPR composite modifier: 10～15 parts, stain: 1～3 part, defoamer: 1～3 part；
Described inner wall tube is made up of by quality proportioning following raw material:
Acrylic resin: 40～60 parts, nano-calcium carbonate: 20～30 parts, EP rubbers EPR composite modifier: 10～15 parts, stain: 1～3 part, defoamer: 1～3 part；
The acrylic resin of described outer wall pipe melt index MFR at a temperature of 0～65 DEG C is: 0.1-0.3 g/10min；The acrylic resin of described inner wall tube melt index at a temperature of 0～65 DEG C is: 0.5-0.9 g/10min；Then stir processing extrusion molding with mixer.
