[0002] PVC pipe is a commonly used communication pipe, but PVC material is a brittle material, which is not resistant to high temperature, has poor weather resistance, high melt viscosity, and difficult plasticization processing, which limits the application of PVC in engineering. Pipe material modification research

[0003] Through long-term research, it has been proved that glass fiber reinforced PVC materials can improve the bending strength, tensile strength and impact strength of PVC composite materials. Although glass fiber PVC materials have good mechanical properties, they can be widely used as structural materials. , but the processing of glass fiber PVC material is difficult, and the dispersion and uniformity are difficult to control

[0004] Although glass fiber can effectively improve the strength of PVC composite materials, at the expense of its toughness, because the intermolecular force of PVC is very strong, the material will deform after being impacted, and the molecular structure will be easily destroyed.

[0005] At present, the common method of enhancing the toughness of PVC pipes is to add various plasticizers to the base material, which has the following problems: plasticizers are low-molecular compounds, and if the amount added is not enough, the plasticizers cannot be well dissolved in the base material In addition, during the processing of composite materials, plasticizers are easily volatilized by heat, which reduces the toughness of PVC materials; if too much plasticizer is added, the intermolecular force of PVC composite materials is further reduced, making it Rigidity and strength are greatly reduced, so in industrial production, rigid PVC products generally do not add plasticizers
