Running belt finished product or semi-finished product and manufacturing method thereof

Abstract

The invention provides a finished or semi-finished running belt and its preparation method, which mainly uses sub-micron or nano-powders with high thermal diffusivity and low thermal conductivity, first disperses the surface active agent, and then adds it to the polymer in a gradually quantitative manner. Propylene (PP), polyethylene (PE), polyamide (PA), polyurethane (PU), polyvinyl chloride (PVC), artificial rubber or natural rubber or their solvents, using a mixing mixer Fully and uniformly mix high thermal diffusivity and low thermal conductivity sub-micron or nano-powders in the base material or solvent, and then after pasting, covering or impregnating pressure-absorbing woven fabrics, knitted fabrics or non-woven fabrics, and finally drying and curing, Manufactured into a running belt with multiple functions such as heat dissipation and prolonging service life.

Description

technical field [0001] The present invention relates to sports equipment, in particular to a method for making a treadmill belt of a treadmill and products thereof. Background technique [0002] General electric treadmills are classified according to the nature and occasion of use: Home Use, Commercial, and Light Commercial. The ones for home use are suitable for sports at home, and the product material specifications are based on an average of 4 people in a family. Each person uses the use intensity of no more than 1 hour at a time to plan manufacturing. Commercial fitness centers open to the general public, large health clubs. Its use intensity is for business purposes, and the use time can reach more than 12 hours a day, and it can run continuously for a long time. Light-duty commercial use is for a specific majority of people, and the use intensity is lower than that of commercial use, but much higher than that of domestic use. It is suitable for closed community bui...

Problems solved by technology

And special materials that are wear-resistant, corrosion-resistant, and slip-resistant should be used to avoid sweat dripping on the pedals during exercise. If special materials are not used, it will be easy to corrode, wear, paint, and rust, which will cause future maintenance costs increase and the safety of athletes

In the past, there has been long-term dynamic friction between the running belt and the running board used in commercial high-end treadmills, which caused the temperature of the running belt to rise above 85°C, because the temperature rise was higher than that used in running belts. The glass transition point (Tg) of the reinforced woven fabric made of polyester (PET) fiber, so that the reinforced woven fabric made of polyester fiber is deformed and destroyed, and the aggregation of the reinforcing material is caused by thermal degradation. The polyester woven fabric and the base material polyvinyl chloride (PVC) will delaminate and reduce the interface strength, which will lead to damage or even breakage of the running belt, especially for commercial high-end treadmills that run for a long time under high load.
