Abstract

The invention provides a PVC pipe material. The PVC pipe material is characterized by being prepared from the following raw materials in parts by weight: 100 parts of polyvinyl chloride, 20 to 30 parts of polyfluoro tert-amino terephthalic acid 1,1'-biadamantane-3,3'-diamine amide, 10 to 15 parts of carboxyl nitrile rubber, 5 to 10 parts of surface-modified glass fiber, 5 to 10 parts of chlorinated polyethylene and 3 to 7 parts of a lubricant. The invention also discloses a preparation method for the PVC pipe material. The PVC pipe material disclosed by the invention has more excellent aging resistance and corrosion resistance, higher mechanical strength and toughness, more excellent impact resistance, better strength and toughness and longer service life, and is safer and more environmentally friendly to use.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PVC pipe and a preparation method thereof. Background technique [0002] In recent years, with the development of production and technology in the chemical and plastic industries, PVC pipes have excellent flame retardancy, wear resistance, chemical corrosion resistance, comprehensive mechanical properties, product transparency, electrical insulation and easier processing, etc. Features, are widely used in industry, construction, agriculture, daily life, packaging, electric power, public utilities and other fields. The development of PVC pipes with excellent performance meets market demand and has extensive social and economic value. [0003] The PVC pipes in the prior art have poor impact resistance due to the poor impact resistance of the pure PVC material itself, especially the poor low-temperature impact resistance, which limits its application in many fields. At ...
