The data in Table 3 shows that the heat distortion temperature of the SAS/PBAT composite material prepared by each embodiment of the invention is more than 79 ℃, and the impact strength is more than 10KJ/m 2 The color difference delta E is less than 1.8, and simultaneously, the high weather resistance, heat resistance and high toughness properties are satisfied.
The results of comparative examples 1-2 show that the SAS resin with lower or higher acrylonitrile mass content is selected to be blended with the PBAT resin, and because the chain segment polarity is not matched, the melt is unstable during shearing blending, even if MABS and PMMA which can react with the PBAT are added to play a two-phase compatibility role, the reaction efficiency is lower, and the corresponding assessment performance index condition of the prepared SAS/PBAT composite material is still poorer; the result of comparative example 3 and comparative example 1 shows that PMMA resin selected by PMMA-1 has small melt index, larger viscosity and higher PBAT processing matching degree under the preferable T content proportion, PMMA can react with PBAT to generate more intermediate products, the composite material is compatibilized, and the composite material can show better performance index.
Comparative example 4 comparative example 1 shows that ABS, which does not contain methyl methacrylate segments, does not work synergistically with PMMA (methyl methacrylate polymer) and that the composite properties are not ideal. Comparative examples 5-6 comparative example 1, the results demonstrate that the addition of MABS and PMMA alone does not achieve the effect of fusing the SAS/PMMA composite and does not achieve a synergistic effect.
