When the folding handcart is folded, the front-rear arm assembly can close, thereby forming a shape similar to a suitcase, which greatly improves neatness of product storage; and the push rod can be erected to serve as a towing handle for dragging, thereby enhancing the convenience of product handling.

The invention relates to the technical field of polymer composite materials, in particular to a TPE-PP composite material for a folding joint of a pet trolley and a preparation method of the TPE-PP composite material. The problems that an existing joint material is insufficient in fatigue resistance and limited in environmental adaptability are solved. The composite material adopts a three-layer structure: a base layer takes high-crystallinity polypropylene as a matrix, and glass fiber reinforcement and elastomer toughening are assisted, so that high rigidity and high strength are realized; the functional layer is composed of a fatigue-resistant thermoplastic elastomer composite system and contains strengthening components such as nano SiO2 so as to disperse stress and prevent crack propagation; the surface layer is a functional layer and contains polytetrafluoroethylene micro powder to provide self-lubricating property, a silver-loaded zinc zeolite antibacterial agent to endow antibacterial and mildew-proof properties, and an anti-ultraviolet additive to improve weather resistance. The three layers form an interpenetrating network structure through co-extrusion and are crosslinked through electron beam irradiation, so that the interlayer binding force is improved. The material can remarkably prolong the service life of the folding joint of the pet trolley and improve the use safety and environmental adaptability.
