The invention solves the deficiencies of the existing water pipes in flame retardancy, heat resistance and strength.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, and in particular relates to a water pipe used in pipeline engineering and a preparation method thereof. Background technique [0002] With the intensification of urbanization, the construction of pipeline engineering is also in full swing. As an important part of pipeline engineering, water pipes are responsible for transporting water bodies. Existing water pipes generally use PVC materials, but the flame retardant performance of PVC water pipes is not high enough, and a large amount of black smoke and toxic gases will be emitted when burning, such as carbon monoxide, benzene, naphthalene and other aromatic compounds, which seriously endanger people's health, and even Threat to people's lives. In addition, the PVC water pipes on the market have poor pressure resistance, and are prone to water leakage, water seepage, rupture, etc., which greatly reduces the service life of PVC pipes and li...
