Embodiment 1

[0037] Preparation of polyester elastomer:

[0038] Raw materials and consumption used in table 1. embodiment 1

[0039]

[0040]

[0041] In a 100ml four-necked bottle, add 1,3-PDO, 1,4-BDO, SuA, SeA, IA according to the amount in Table 1, and put the mixture under N 2 Stir mechanically under atmosphere and heat to 180°C, and keep at 180°C for 2h. Then cool to room temperature, add 0.1wt% tetrabutyl titanate as a catalyst, then gradually increase the temperature to 220°C, pre-condense at -0.06MPa for 1 hour, and then polycondense at -0.1MPa until the product has a climbing effect. Small molecules such as propylene glycol and butanediol produced in the transesterification reaction were distilled under reduced pressure, and finally the product bio-based polyester PPBSIS was obtained.

[0047]

[0048]

[0049] In a 100ml four-necked bottle, add 1,2-PDO, 1,4-BDO, and AA according to the dosage in Table 2. Put the mixture in N 2 Mechanically stirred and heated to 160°C under atmosphere, and kept at 160°C for 2h. Then the temperature was raised to 180°C and kept at 180°C for 2h. Then cool to room temperature, add 0.2wt% tetrabutyl titanate as a catalyst, then gradually increase the temperature to 220°C, pre-condense at -0.06MPa for 1 hour, and then polycondense at -0.1MPa until the product has a climbing effect. Small molecules such as 1,2-propanediol and butanediol produced in the transesterification reaction were distilled under reduced pressure, and finally the product bio-based polyester PPBA was obtained. Since the obtained product is a saturated system rubber without double bonds, the color of the product is relatively light, and the...

Abstract

The invention provides a rubber-plastic blended composite material of polyester elastomer toughened and modified carbon dioxide-based plastic, and a preparation method thereof. According to the invention, a polyester elastomer is adopted to perform toughening modification on carbon dioxide-based plastic, so the strength loss of the carbon dioxide-based plastic is reduced as much as possible while the toughness of the carbon dioxide-based plastic is improved; and meanwhile, the molecular chain structure of a polyester product is controlled by designing and screening the types and proportions of different polyester monomers, so that the two materials have good compatibility, therefore, the polyester elastomer has a better toughening effect on the carbon dioxide-based plastic; besides, the bio-based polyester elastomer is used as a degradable material, and the prepared bio-based polyester elastomer modified carbon dioxide-based plastic is also environment-friendly degradable plastic and has higher value in the aspect of environmental protection.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a rubber-plastic blending composite material of toughened modified carbon dioxide-based plastics, in particular to a rubber-plastic blended composite material of polyester elastomer toughened modified carbon dioxide-based plastics and its preparation method. Background technique [0002] At present, in the field of plastics, carbon dioxide-based plastics are a new type of environmentally friendly plastics, and they are widely concerned with carbon dioxide as raw materials. They have extremely broad application prospects in the future and are in line with the concept of sustainable development. However, in the current application process of carbon dioxide-based plastics, their high brittleness and insufficient toughness have become important problems hindering their application. [0003] Among all the current research on plastics, there has never been any research on ...
