An ultra-quiet polypropylene piping material

Abstract

The invention relates to the technical field of polypropylene pipeline materials, and discloses a polypropylene pipeline material with ultra-quiet effect. In parts by weight, the raw materials include: 80-90 parts of polypropylene grafted with metal organic framework materials; lubricant 1~ 3 parts; 0.5~1 part of antioxidant; 0.2~0.5 part of ultraviolet absorber. In the present invention, the metal organic framework material is grafted on the polypropylene matrix, and its hollow porous structure can increase the reflection area of ​​the material to sound waves, thereby effectively improving the sound absorption performance of the polypropylene material, so that the obtained pipeline material has an ultra-quiet effect; At the same time, metal-organic framework materials have good mechanical properties, which can improve the high temperature resistance and mechanical properties of pipeline materials; the functional groups on the organic ligands of metal-organic frameworks can further react with various functional components such as antibacterial components. The functional components are modified on the polypropylene matrix, so as to improve the various functions of the pipeline material.

Description

technical field [0001] The invention relates to the technical field of polypropylene pipe materials, in particular to a polypropylene pipe material with ultra-quiet effect. Background technique [0002] In recent years, with the continuous improvement of people's living standards in our country, the majority of residents have higher and higher requirements for the quality of the living room environment, and the noise problem of building drainage pipes has attracted more and more attention. According to the provisions of the national standard GBJ118-2010: (taking residences as an example) the noise in the bedroom at night shall not exceed 30dB, and the maximum shall not exceed 40dB. In actual tests, the noise generated by most drainage pipes and fittings is far greater than 40dB. In engineering examples, there is no shortage of noises from pipelines that disturb residents' sleep and produce annoyance effects, as well as neurasthenia and other non-specific diseases caused by ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the limited noise effect of the pipe when adding inorganic fillers such as talcum powder and barium sulfate in the prior art to improve the mute effect of the polypropylene pipe material; and due to the dispersion of the inorganic filler and the compatibility with the polypropylene matrix Poor performance, resulting in many internal defects of the pipe, which will reduce the mechanical properties of the pipe, which is not conducive to the application of the pipe. A polypropylene pipe material with ultra-quiet effect is provided, and the metal organic framework material is grafted on the polypropylene matrix. In general, metal-organic framework materials with hollow porous structures can effectively improve the quiet effect of polypropylene materials, and at the same time can make pipes have good mechanical properties, so that polypropylene pipe materials can meet the requirements of pipes in various complex environments
