Reinforced protective material for pipe and preparation method thereof

Abstract

The invention relates to a reinforced protective material for pipe. The material comprises the following components by weight: 100 parts of copolymerization grade polypropylene, 20-40 parts of nano ceramic powder liquid, 5-10 parts of a cold resistant plasticizer, 4-6 parts of a coupling agent, 4-6 parts of a reinforcing agent and 4-8 parts of a stabilizing agent. The material can improve the surface hardness of the pipe, so that the pipe hardly scratches in the use process, and gains good anti-cracking performance. The invention also provides a preparation method of the material.

Description

technical field [0001] The invention relates to a pipe reinforced protective material and a preparation method thereof, belonging to the technical field of pipes. Background technique [0002] The laying link often plays an important role in the cost and energy consumption of plastic pipeline projects. The basis of trenchless laying technology is to lay the pipeline to the required underground line position by using the trenchless method. The most widely used trenchless technology for laying concrete pipes and steel pipes is the pipe jacking method. In the laying of plastic pipes The most widely used non-excavation technology is the horizontal directional drilling method, because the non-excavation laying needs to pull or push the plastic pipe into the hole drilled at the bottom or into the old pipe to be repaired. During this process, the surface of the pipe will inevitably be damaged. It is likely to be directly contacted with sharp stones to form a concentrated load in t...

The most widely used method in the trenchless laying of concrete pipes and steel pipes is the pipe jacking method. In the laying of plastic pipes The most widely used non-excavation technology is the horizontal directional drilling method, because the non-excavation laying needs to pull or push the plastic pipe into the hole drilled at the bottom or into the old pipe to be repaired. During this process, the surface of the pipe will inevitably be damaged. Damage, it is likely to directly contact sharp stones, etc. to form a concentrated load in the pipe wall, thereby damaging the high stress concentration, resulting in potential use risks, while the surface of ordinary polyethylene pipes is easy to scratch, and the cracking resistance performance when subjected to point loads also limited
