Description

Technical Field

[0001] The utility model belongs to the field of rubber industry, and particularly relates to a device for simulating accelerated aging of rubber tape products resistant to medium. Background Art

[0002] As one of the earliest products in the rubber industry, adhesive tape products utilize a fabric skeleton, exhibiting both elasticity and flexibility. Some adhesive tape products come into contact with media such as oils, acids, and alkalis under operating conditions, placing higher performance requirements on these products. Adhesive tape products offer excellent elasticity, a wide operating temperature range, ease of cutting and splicing into various shapes, adaptability, and simplified manufacturing. While maintaining the integrity of the tape's form, exposure to hot air or the working environment can weaken the skeleton due to absorption of the media and heat. The surface rubber layer ages, losing its protective function, weakening the bond between the skeleton and the rubber, or reducing the tensile strength of the skeleton. This can lead to failure of the tape product, resulting in accidents and significant losses to production and daily life. Therefore, simulating aging tests under harsh conditions is necessary to estimate the service life of adhesive tape products, which has positive implications for social, economic, production, and daily life. How to simulate the usage status of adhesive tape products under non-operating conditions and estimate their service life is a major challenge that the adhesive tape products industry currently wants to overcome.
