Sour acid amides 30-40 parts, 10-15 parts, stearic acid 20-25 parts of low molecular weight polyethylene wax；
It is described improve the flexible modifying agent of large bore dual-wall polyproplyene corrugated pipe preparation method be：
1. taken raw material is added into grinder together, is polished into mixed slurry, grinder temperature control below 25 DEG C, so
Gained slurry is poured into pallet afterwards, pallet is put into X-ray production apparatus in 700- by severity control of the slurry in pallet in 5-8cm
Irradiated 10-15 minutes under the power of 900W；
2. slurry is poured into homogenizer, is stirred 25-35 minutes with the speed of 600-700rpm under normal temperature；
3. it is filling after the assay was approved, obtain final product.
Used as preferred embodiments of the present invention, described improved large bore dual-wall polyproplyene corrugated pipe is flexible modified
Agent is made up of the raw material of following weight portion：
47 parts of maleic anhydride inoculated polypropylene, 12 76 parts of nylon, 54 parts of alkali-free long glass fibres, the second of gamma-amino propyl group three
29 parts of TMOS, 19 parts of tetrapentaerythritol ester, 11 parts of chlorinated benzotriazole, double 33 parts of the stearic amides of vinyl, low molecule
12 parts of weight northylen wax, 23 parts of stearic acid.
The flexible modifying agent of large bore dual-wall polyproplyene corrugated pipe that improves of the invention is in bellows manufacturing process
It is added in proportion in polypropylene and uses, the modifying agent can effectively improves the pliability of large bore dual-wall polyproplyene corrugated pipe,
It is unlikely to fracture in the case where there is moderate finite deformation, body can be adapted to by appropriate deformation when surface subsidence,
Reduce the generation of security incident.
