Embodiment 1
[0023] A polyethylene pipe for non-excavation engineering, including 100kg of high-density polyethylene, 3kg of mica, 6kg of functional modifier, 0.5kg of silane coupling agent, 3kg of color masterbatch and 3kg of anti-oxidation masterbatch.
[0024] The preparation method of the functional modifier is as follows.
[0025] S1: In container 1, add N,N-dimethylacetamide (DMAC) and polyvinylidene fluoride, heat to 80°C and stir at 120r / min for 4h.
[0026] S2: In container 2, add glycerol methacrylate and polyacrylamide, and vibrate ultrasonically for 30 minutes at a constant temperature of 35°C.
[0027] S3: Pour the solution in container 2 into container 1, stir at 80°C and 120r / min for 10 minutes, then pour all the solution into a container with 0-20°C cold water, rinse, precipitate and dry to obtain functional modification agent.
[0028] Further, the polyvinylidene fluoride is in powder form with a particle size of 800 mesh.
[0029] The preparation method of the above-me...
