Description

Technical Field

[0001] The utility model relates to the technical field of artificial leather testing equipment, in particular to an amine resistance testing device for PVC artificial leather. Background Art

[0002] PVC artificial leather is widely used in industries such as furniture, automotive interiors, footwear, and luggage, attracting market attention due to its relatively low price and excellent physical and chemical properties. However, during actual use, PVC artificial leather comes into contact with various chemicals, particularly amine compounds. Amine compounds are highly corrosive to PVC materials, easily causing aging, discoloration, and hardening of PVC artificial leather, which in turn affects its service life and aesthetics. Therefore, testing the amine resistance of PVC artificial leather has become a key step in material quality testing.

[0003] At present, it is known through searching that a device for testing the amine resistance of PVC leather with patent number CN214703644U includes a container body, a cover body, a medicine box and a sample rack. The container body is a cylindrical structure with an upper end opening. The container body is made of a high-temperature resistant colorless and transparent material. The cover body is buckled on the upper port of the container body. A sealing ring is provided on the outer peripheral side of the lower end surface of the cover body. The medicine box and the sample rack are placed at the bottom of the container body. A vacuum valve is provided on the cover body. The structural design is simple and reasonable. The cover body and the container body are sealed by a sealing ring. The sealed connection ensures the sealing of the test device when testing the amine resistance of PVC leather samples, avoids the interaction between the amine catalyst molecules in the test device and the outside air, and ensures the accuracy of the test results; the PVC leather samples can be hung on the sample rack, thereby ensuring the overall heat transfer uniformity of the PVC leather samples and sufficient contact between the PVC leather samples and the amine catalyst molecules, further ensuring the accuracy of the amine resistance test results of the PVC leather samples; the test device has small error, high reproducibility and strong practicality in testing the amine resistance of PVC leather samples.

[0004] Although the above-mentioned comparative document can test the amine resistance of PVC leather, the test speed is slow because the reagent box adopts a fixed setting, and the internal air circulation rate is low, which makes the contact rate between the reagent and the PVC leather smaller, and the amine resistance test time of the PVC leather is greatly prolonged.
