TABLE 1 Performance test results of the polypropylene micro-foamed composites prepared in examples 1-5 and comparative examples
Comparing examples 1-5 with the comparative example, it can be seen that the tensile strength and the bending strength of the polypropylene micro-foamed composite material are not greatly changed, and the notch impact toughness is improved after the gas adsorbent and the gas barrier agent are added. The defects of surface gas marks, silver lines and the like are less and less along with the addition of the gas adsorbent and the gas barrier agent, and the foam holes are more and more uniform and compact (see figure 1). Further, the addition of the gas adsorbent and the gas barrier can regulate and control the dissolution, diffusion and migration of gas in the polymer melt, and reduce the gas migration and diffusion to the surface of the polymer, thereby achieving the purpose of improving the surface quality of the foamed product. In addition, as can be seen from fig. 2, compared with the comparative example, the polypropylene micro-foamed composite material obtained in the example has more uniform inner cells and an increased number of cells, so that the foaming uniformity (the reason for the improved notch impact toughness) and the foaming rate (the weight reduction and other foaming related properties of the composite material) of the composite material can be further improved under the formula system of the technical scheme.
