Anti-scaling PPR pipe with low-temperature toughness and preparation method thereof

Abstract

The invention provides an anti-scaling PPR pipe with low-temperature toughness and a preparation method of the anti-scaling PPR pipe, and belongs to the technical field of high polymer materials and building materials. The invention discloses an anti-scaling PPR pipe with low-temperature toughness. The anti-scaling PPR pipe comprises 10 parts of PPR resin, 4-6 parts of a nucleating agent, 8-12 parts of an anti-scaling agent, 2-4 parts of PPH resin and 6-8 parts of an elastomer. A random copolymer polypropylene, an ethylene propylene diene monomer elastomer and a pegmalan nucleating agent are blended for toughening, so that the compatibility of the toughening agent and a PPR matrix and the crosslinking degree of a chain segment are improved, and the low-temperature impact property of PPR isgreatly improved. By adding the surface-modified nano zinc oxide, the compactness of the PPR pipe is improved, and the anti-scaling performance of the PPR pipe is effectively improved. Meanwhile, byadding an nano anti-ultraviolet antibacterial agent, scaling caused by bacterium breeding can be prevented, the light resistance and aging resistance of the pipe are enhanced, and the service life ofthe PPR pipe is guaranteed. The anti-scaling PPR pipe with the low-temperature toughness is simple in process and low in cost. The method is suitable for production of the pipes.

Description

technical field [0001] The invention provides an anti-scaling PPR pipe with low-temperature toughness and a preparation method thereof, belonging to the technical field of polymer materials and building materials. Background technique [0002] As a new type of green building material, random copolymerized polypropylene (PPR) pipes are widely used in civil buildings and industrial water supply and drainage facilities. However, due to the poor heat resistance and low temperature impact resistance of PPR, especially at low temperature Under the environment, PPR pipes will be embrittled at low temperature, so in cold regions such as the north, it is very easy to limit its application due to damage during transportation, construction, and use. Contents of the invention [0003] The object of the present invention is to provide an anti-fouling PPR pipe with low temperature toughness and a preparation method thereof, so as to improve the service life of the PPR pipe and reduce th...
