Title:
AGING-RESISTANT RUBBER TUBING FOR PHYSICAL TRAINING, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/134093
Kind Code:
A1
Abstract:
An aging-resistant rubber tubing for physical training, comprising an inner core layer (1), a braided layer (2), and an elastic outer layer (3) which are sequentially arranged. A mixed layer (4) is arranged in the braided layer (2); the mixed layer (4) comprises an adhesive layer and a tourmaline powder layer; the tourmaline powder layer is a mixture of tourmaline powder and rare earth elements. By adding a negative ion additive, the rubber tubing can generate negative ions, thereby realizing the purposes of inhibiting bacterial growth, and purifying air; the layers are provided, the inner core layer (1), the braided layer (2), and the elastic outer layer (3) all have elasticity, and particularly, cooperation of an elastic wire in the inner core layer (1) with an elastic sleeve (12) and an elastic inner layer (13) can enable the overall stress distribution to be more balanced; moreover, an adhesive having high ductility in the prior art is used as the adhesive layer, thereby ensuring that the rubber tubing can be extended by 1 to 5 times under the action of external force, and can be quickly retracted after the external force is eliminated; after high-strength stretching, the elastic force can be uniformly dispersed in the rebound process, and the service life is effectively prolonged.
