Abstract

The invention discloses a toughened and modified PVC (polyvinyl chloride) plastic pipe and a preparation method thereof. The toughened and modified PVC plastic pipe is prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 15 to 35 parts of high-cis butadiene rubber, 0.5 to 1.5 parts of coupling agents and 0.2 to 0.6 part of inorganic fillings. The toughened and modified PVC plastic pipe is obtained by using an extrusion forming or injection molding forming preparation process. By using a molecular structure design method, the high-cis butadiene rubber is used as toughening materials to be uniformly added into the PVC resin, so that the low-temperature brittleness of the polyvinyl chloride plastic pipe is improved, and the mechanical intensity and the heat-resistant performance are enhanced.

Description

technical field [0001] The invention relates to the field of polymer compound compositions, in particular to a toughened modified PVC plastic pipe and a preparation method thereof. Background technique [0002] Plastic pipes have the advantages of light weight, high strength, simple manufacturing methods, low economic cost, convenient processing and use, corrosion resistance, and long life. The main application pipes in the field. As an important part of the field of new chemical materials, the research and development of modified plastic pipes has become one of the key scientific and technological fields. [0003] Polyvinyl chloride (PVC) plastic pipe is an important polymer material that is widely used in many plastic pipes. PVC plastic pipe has excellent physical and chemical properties such as good flame retardant effect, strong acid and alkali resistance, high structural strength, and good electrical insulation. However, since the PVC resin material itself is a kind ...
