Abstract

The invention relates to the field of polymer composite materials, in particular to an ultra-high molecular weight polyethylene reinforced modified polypropylene straight-wall pipe which is formed by an inner layer and an outer layer through hot melting compounding, corrugations of the outer layer are of a polygonal n-shaped waveform structure, and the outer layer and the inner layer are both made of ultra-high molecular weight polyethylene reinforced modified polypropylene composite materials. The ultra-high molecular weight polyethylene reinforced modified polypropylene composite material comprises the following raw materials: PPR, PPB, ultra-high molecular weight polyethylene, linear polyethylene LLDPE, a compatible flexibilizer, a beta nucleating agent, a molten fat regulator, nanoscale talcum powder, 1250-mesh talcum powder, white carbon black, diffusion oil, a silane coupling agent, a light stabilizer, an antioxidant 1010 and an antioxidant 168. The ring stiffness, the ring flexibility, the impact resistance and the high and low temperature performance are improved.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to an ultra-high molecular weight polyethylene reinforced modified polypropylene straight-wall pipe. Background technique [0002] At present, the raw materials used in the production of double-wall corrugated pipes in my country are mainly polyvinyl chloride (PVC), polyethylene (PE) and polypropylene (PP). The advantage of the PVC double-wall corrugated pipe is that the rigidity of the PVC material is high, and the elastic modulus of the material is larger than that of the polyethylene material. Therefore, a smaller moment of inertia can be used to achieve the same ring stiffness, and a smaller wall thickness can be used if the same wave design is used. Therefore, within a certain range, the PVC double-wall corrugated pipe is economically advantageous, but due to the poor fluidity and thermal stability of the PVC material, it is difficult to produce large-diameter double...
