Description

Technical Field

[0001] This utility model relates to the field of crosslinking degree detection technology, specifically to an auxiliary fixture for detecting the crosslinking degree of micro-crosslinked polyolefin materials. Background Technology

[0002] Micro-crosslinked polyolefin materials are a class of high-performance polymer materials obtained through mild crosslinking modification. They combine the basic mechanical properties of polyolefins with the improved heat resistance and solvent resistance brought about by the crosslinking structure, and are widely used in pipes, films, cable insulation layers, and other fields. The degree of crosslinking, as a key indicator characterizing the extent of crosslinking in a material, directly affects the material's mechanical strength, aging resistance, and processing stability. Therefore, accurate measurement is necessary in material production, application, and quality testing.

[0003] Currently, the degree of crosslinking of micro-crosslinked polyolefin materials is mainly detected using solvent extraction, differential scanning calorimetry (DSC), and mechanical property testing methods. Among these, solvent extraction has become the mainstream method in the industry due to its simplicity and intuitive results. Its principle is to remove linear molecules and low-crosslinking components from the material by immersing it in a solvent; the remaining gel content is the core characterization parameter for the degree of crosslinking. During the testing process, the sample must be fixed in a container to prevent floating, tangling, or agglomeration, ensuring thorough and uniform extraction.

[0004] In practice, staff need to place the sample into a stainless steel wire mesh bag, and then immerse the bag and sample in solvent using the wire. However, this structure is extremely unstable in securing the sample, making it easy for it to slip into the flask. This makes the sample difficult to remove later. Also, due to the presence of the wire, the stopper cannot completely seal the opening of the flask, causing the boiling solvent to evaporate. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary fixture for detecting the degree of crosslinking of micro-crosslinked polyolefin materials. This fixture aims to improve the existing crosslinking degree detection process, which is prone to the steel wire suspending the sample slipping into the flask. At the same time, due to the presence of the steel wire, the stopper cannot completely seal the opening of the flask, resulting in the evaporation of boiling solvent.
