Abstract

The invention relates to the technical field of polymer composite materials, in particular to an MUPO double-layer double-wave structure wall pipe which is formed by an inner layer and an outer layer through hot melting compounding, and the inner layer and the outer layer are both made of nano modified polyolefin materials. Each nano modified polyolefin material comprises the following raw materials in parts by weight: 60-70 parts of polyolefin, 5-10 parts of a composite cold-resistant elastomer toughening agent and 35-20 parts of an inorganic nano composite toughening and reinforcing material, the nano modified polyolefin material comprises the following raw materials in parts by weight: 60-70 parts of polyolefin, 5-10 parts of a composite cold-resistant elastomer toughening agent and 35-20 parts of an inorganic nano composite toughening and reinforcing material, and he composite cold-resistant elastomer toughening agent is prepared from the following ingredients in parts by weight: 80 parts of ethylene-octylene copolymer, 20 parts of EVA (Ethylene Vinyl Acetate), 3-6 parts of styrene, 3-6 parts of maleic anhydride and 1-3 parts of dicumyl peroxide. The ring stiffness, the ring flexibility, the cold resistance, the impact resistance and the like are obviously improved, and the performance requirements of the buried blow-off pipe can be met.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a MUPO double-layer double-wave structure wall pipe. Background technique [0002] Double-wall corrugated sewage pipes are mainly used in municipal drainage and sewage systems. At present, the raw materials for the production of double-wall corrugated pipes mainly include polyvinyl chloride (PVC), polyethylene (PE) and polypropylene (PP). Some domestic ordinary pipe materials may have problems such as insufficient melt strength and product ring stiffness not meeting the requirements when producing large-diameter double-wall corrugated pipes. [0003] Ring stiffness and ring flexibility are the most important performance indicators of pipes, because in the application of buried drainage pipes, pipes do not bear internal pressure or low pressure, but only bear external pressure loads (including dynamic loads and static loads). If the ring stiffness of the pipe...
