Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, and more specifically, to a masterbatch performance detection device. Background Art

[0002] Masterbatch is a granular aggregate obtained by uniformly loading an extraordinary amount of modified chemical additives in a carrier resin. Compared with adding modified chemical additives directly to the product: the masterbatch has a good dispersion effect, which can make the performance of the product uniform. The carrier resin of the masterbatch has good compatibility with the product resin, which makes the performance of the product with the masterbatch added better. The masterbatch is safe to use and has comprehensive functions. By adding different chemical additives, the masterbatch has the advantages of good impact resistance, good tensile resistance, and good flame retardant effect. Flame retardant masterbatch is added with flame retardant during the manufacturing process of the masterbatch, so that the masterbatch has the property of significantly delaying the spread of flame. The flame retardant masterbatch needs to be tested for its performance after granulation. At present, the flame retardant effect is judged by igniting the masterbatch and observing its combustion morphology. However, this detection method has low accuracy. Due to the small volume of a single masterbatch, if a single masterbatch is ignited, the burning time is very short and the observation effect is very poor. If the produced masterbatch is first melted into a sheet structure to form a thin-walled structure similar to a plastic product, the sheet product can not only detect the flame retardant effect of the masterbatch, but also the tensile resistance and impact resistance, etc., and the accuracy of the test results will be greatly improved.
