Abstract

The invention discloses a glass-fiber rigid communication pipe material. The glass-fiber rigid communication pipe material comprises, by weight, 60-90 parts of PVC, 6-13.5 parts of calcium carbonate, 3-22.5 parts of glass fibers, 0.3-0.8 part of steric acid, 3.5-6 parts of Ca/Zn composite stabilizer, 0.4-0.6 part of PE wax, 0.1-0.4 part of antioxidant and 0-1 part of pigment. The glass-fiber rigid communication pipe material has the advantages that an appropriate amount of the short glass fibers are used to increase the strength of the PVC communication pipe material, conditions in the preparation process are improved strictly, and the high-strength glass-fiber rigid communication pipe material can be produced.

Description

technical field [0001] The invention relates to the field of communication pipes, in particular to a glass fiber rigid communication pipe and a preparation method thereof. Background technique [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. The material of the pipe is modified. [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 more difficult, and the dispersion and uniformity are difficult to control.
