Reinforced protective material for pipe and preparation method thereof

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.
