Description

technical field

[0001] The invention belongs to the technical field of plastic materials, and in particular relates to a special material for multifunctional modified random polypropylene pipes and a preparation method and application of the special material. Background technique

[0002] Ethylene-propylene random copolymerization polypropylene (PP-R) is a kind of polypropylene, which is obtained by copolymerization of propylene and a small amount of ethylene under the action of certain temperature, pressure and catalyst. The structural characteristics make PP-R have properties that homopolypropylene (PP-H) or block graft copolymerized polypropylene (PP-B) do not have. In recent years, it has achieved rapid development in pipeline applications and other aspects. In the pipeline system mainly used at present, ethylene propylene random copolymer polypropylene (PP-R) not only has the advantages of light weight, good strength, corrosion resistance, long service life, simple and ...
