| titleOfInvention | Hot melt adhesive thermal stability testing method and device |
| abstract | The invention discloses a hot melt adhesive thermal stability testing method, which comprises the following steps: 1) preparing a hot melt adhesive to be tested; 2) heating the hot melt adhesive to be molten, and observing the color and appearance changes of the hot melt adhesive; 3) under the condition of melting, putting the hot melt adhesive into a thermal stability testing device for filtering; 4) and cooling the filtered hot melt adhesive, and then performing a softening point test and a thin consistency test. The filtering step is added before the testing of the thin consistency and the softening point, so that the influence of carbide in the hot melt adhesive is eliminated, and the error of the testing result is effectively reduced; the carbide in the hot melt adhesive can be separated in the filtering process, and the carbide amount can be accurately obtained after collection and weighing, so that the thermal stability of the hot melt adhesive can be conveniently quantized and compared; the method is simple to operate, overcomes subjective errors caused by observation of different people in the existing method, quantifies the test result and has high precision. |
