Description
Technical field
The present invention relates to tubing technical field, and in particular to a kind of PPR pipe and its preparation with excellent low temperature toughness
Method.
Background technology
Atactic copolymerized polypropene（PPR）Tubing is that the third generation of the MODIFIED PP tubing of European early 1990s exploitation is produced
Product.PPR is obtained, wherein the ethene containing about 3% with atactic copolymerized polypropene as base-material after modified treatment.PPR pipe is with stainless
It is erosion, non-leakage, non-scaling, not only heat-resisting but also pressure-resistant, can with building with the longevity many advantages, such as, be increasingly subject to the favor of people.But
It is that PPR pipe can occur low temperature brittleness, at low ambient temperatures, PPR pipe is damaged easily in transportation, this great system
About use of the PPR pipe in extremely frigid zones.
Elastomer has elasticity very high, and its glass transition temperature is very low, can significantly improve the black brittleness of PPR.But simultaneously
What is brought is declining to a great extent for PPR rigidity, intensity and heat distortion temperature.Inorganic rigid particle has strengthening action, and it can same bullet
Gonosome coordination plasticizing PPR, the tubing for preparing can also be kept while with preferable low-temperature flexibility it is original rigidity,
Intensity.But, the compound system of elastomer, inorganic rigid particle and PPR is often difficult to obtain single, stably phase, institute
Obtained PPR pipe is then had too many difficulties to cope with pressure-resistant aspect.
Beta-crystalline polyacrylic has the advantages that elastic modelling quantity and yield strength is low, impact strength and heat distortion temperature are high, Gao Han
Amount Beta-crystalline polyacrylic is the ideal style of polypropylene toughening, and addition beta nucleater is to obtain having for the generally acknowledged row of high content beta crystal
The approach of effect.But from the point of view of practical situations, polyacrylic beta-crystalline form content is but unable to reach expection, the low temperature of PPR pipe
Toughness also cannot effectively improve.In sum, it is highly desirable to research and develop a kind of good low-temperature flexibility, rigidity and intensity
The high, PPR pipe of good pressure-resistant performance.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of PPR pipe with excellent low temperature toughness,
