Abstract

The invention discloses a modified fiber reinforced PVC plastic pipe and a preparation method thereof. The prepared modified fiber reinforced PVC plastic pipe is prepared from, by weight, 100 parts of PVC, 1-15 parts of modified fiber material, 0.001-0.005 part of adhesive, 0.05-0.25 part of filler, 0.01-0.05 part of auxiliary and 0.02-0.15 part of coupling agent. The preparation method includes the steps of preparation of the modified fiber material, mixing and extrusion forming. The tensile properties, mechanical strength, toughness and bending resistance of the prepared modified fiber reinforced PVC plastic pipe are remarkably improved.

Description

technical field [0001] The invention relates to the field of plastic pipes, in particular to a modified fiber reinforced PVC plastic pipe and a preparation method thereof. Background technique [0002] Plastic pipe is a new generation of building materials emerging with the continuous improvement of chemical technology. It is especially suitable for the construction of various pipe networks. It has outstanding characteristics such as small flow loss energy, good durability and anti-aging performance, and convenient construction and laying. And has obvious cost advantages. [0003] Polyvinyl chloride (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. It is one of the most widely used plastic pipes on the market. However, the tensile level and toughness of PVC plastic pipes are poor. When PVC plastic pipes are subjected to large tens...
