Examples
Embodiment 1
[0038] After drying polylactic acid, polycarbonate and high-efficiency comb-type compatibilizer in a vacuum oven at 80°C, 100°C, and 50°C for 24 hours, 30g of polylactic acid, 70g of polycarbonate, and 5g of high-efficiency comb-type compatibilizer, After mixing and stirring at room temperature, add it to the internal mixer at one time. The temperature of the internal mixer is 240 ° C, the screw speed is set at 50 rpm, and the melt blending is performed for 5 minutes to obtain a high-vegetative high-performance polylactic acid alloy material.
[0039] The polylactic acid alloy material prepared in Example 1 was hot-pressed into sheets in a hot press at 240°C, and a standard test sample was prepared with a standard dumbbell-shaped punching knife for performance testing. The results are shown in Table 1.
Embodiment 2
[0041] After drying polylactic acid, polycarbonate and high-efficiency comb-type compatibilizer in a vacuum oven at 80°C, 100°C, and 50°C for 24 hours, 50g of polylactic acid, 50g of polycarbonate, and 5g of high-efficiency comb-type compatibilizer, After mixing and stirring at room temperature, add it to the internal mixer at one time. The temperature of the internal mixer is 240 ° C, the screw speed is set at 50 rpm, and the melt blending is performed for 5 minutes to obtain a high-vegetative high-performance polylactic acid alloy material.
[0042] The polylactic acid alloy material prepared in Example 2 was hot-pressed into sheets in a hot press at 240°C, and a standard test sample was prepared with a standard dumbbell-shaped punching knife for performance testing. The results are shown in Table 1.
Embodiment 3
[0044] After drying polylactic acid, polycarbonate and high-efficiency linear compatibilizer in a vacuum oven at 80°C, 100°C, and 50°C for 24 hours, 50g of polylactic acid, 50g of polycarbonate, and 5g of high-efficiency linear compatibilizer were mixed at room temperature After mixing and stirring, add it to the internal mixer at one time. The temperature of the internal mixer is 240 ° C, the screw speed is set at 50 rpm, and the melt blending is performed for 5 minutes to obtain a high-vegetative high-performance polylactic acid alloy material.
[0045] The polylactic acid alloy material prepared in Example 3 was hot-pressed into sheets in a hot press at 240°C, and a standard test sample was prepared with a standard dumbbell-shaped punching knife for performance testing. The results are shown in Table 1.
