Example Embodiment

[0037] Example 1-12

[0038] Polylactic acid (PLA), nylon 11 (PA11) and elastomer (EGMA-g-SAN) were dried in a vacuum oven at 80°C for 24 hours. PLA / Nylon 11 and elastomer were weighed according to the mass ratio in Table 1. After mixing and stirring at room temperature, it is added to the internal mixer, the internal mixer temperature is 200°C, the screw speed is set to 100 rpm, and the material is discharged after 5 minutes of mixing.

[0039] The above-mentioned mixed samples were hot pressed into a sheet with a thickness of 1 mm in a hot press at 210° C., and standard test specimens were prepared with a standard dumbbell-shaped punching knife for performance testing. The results are shown in Table 1.

Example Embodiment

[0044] Example 13

[0045] After polylactic acid (PLA), nylon 11 (PA11) and elastomer (EGMA-g-SAN) are dried in a vacuum oven at 80°C for 24 hours, a quantitative amount of PLA and EGMA-g-SAN are first mixed and then added to the internal mixer , The internal mixer temperature is 200℃, the screw speed is set to 100rpm, and the material is discharged after 5 minutes of mixing. The sample was pulverized and mixed with a quantitative nylon 11, added to an internal mixer, the temperature of the internal mixer was 200°C, the screw speed was set to 100 rpm, and the material was discharged after banburying for 5 minutes. The mass ratio of the three raw materials used is PLA / nylon 11=55g / 45g, and EGMA-g-SAN is 6% of the total mass of PLA and nylon 11.

Abstract

The invention discloses a polylactic acid/polyamide 11 alloy material. The polylactic acid/polyamide 11 alloy material is mainly prepared by melting and blending polylactic acid, polyamide 11, and a third component by using melting and mixing equipment; based on the mass of the polylactic acid and the polyamide 11, the polylactic acid is 5 to 95 mass percent, and the polyamide 11 is 5 to 95 mass percent; and the third component is 0 to 15 percent based on the total mass of the polylactic acid and the polyamide 11, wherein 0 infinitely approaches 0 but is not 0; and the third component is an elastomer containing an epoxide group. The polylactic acid/polyamide 11 alloy material is high in hardness, modulus and tensile strength, the impact resistance is greatly improved and the polylactic acid/polyamide 11 alloy material meets the performance using requirements of a structural material.

Description

technical field [0001] The invention relates to the fields of polymer technology and ecological environment materials, in particular to a polylactic acid / nylon 11 alloy material derived from high-performance whole biomass and a preparation method thereof. Background technique [0002] Resources and the environment are major and important issues facing human beings. Traditional polymer materials are derived from non-renewable petrochemical resources. Before the depletion of non-renewable petroleum resources, renewable polymer materials, especially those derived from biomass, have attracted global attention. In the past 10 years, polylactic acid materials have received widespread interest from the industry. The reasons include: First, the raw materials for polylactic acid production are derived from plants and do not depend on petroleum. Before the depletion of non-renewable petroleum resources, renewable products must Will become a worldwide commodity. The second is that po...
