Drainage pipe for municipal construction and preparation method thereof

Abstract

The invention discloses a drainage pipe for municipal construction, belongs to the technical field of municipal pipelines, and solves problems of easy fracture of existing pipe materials and poor tensile strength, impact strength and fracture tensile properties of drainage pipes. The technical main points are as follows: the drainage pipe comprises the following raw materials in parts by weight: 100-120 parts of PVC resin, 28-42 parts of micro-silica, 15-30 parts of nylon fiber, 7-11 parts of an anti-aging agent, 6-10 parts of a heat stabilizer, 6-10 parts of a lubricant, 4-8 parts of a filling agent, 5-9 parts of a toughening agent, and 5-9 parts of a colorant. The nylon fiber is adopted to strengthen the drainage pipe, the impact resistance of the pipe material is improved due to good toughness, the point load and the uneven settlement of the foundation can be effectively resisted, the environment cracking resistance is improved, the external force impact on the drainage pipe can beeffectively resisted, the installation and transportation is convenient, and the safety of the pipeline operation is improved.

Description

technical field

[0001] The invention relates to the technical field of municipal pipelines, in particular to a drainage pipe for municipal construction and a preparation method thereof. Background technique

[0002] Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, commonly known as "sewage pipes", which are usually called municipal drainage pipes in engineering. According to the current situation of facilities under municipal roads in my country, different pipelines are generally set up, such as electricity, communication , gas, water supply and drainage pipes, etc., and the drainage pipes consider the rain and sewage diversion measures, that is, the rainwater is generally discharged into the river nearby, and the sewage is discharged into the sewage treatment plant, so the municipal drainage pipes include rainwater and sewage pipes.
