Embodiment 1～22

[0057] The content of each component in the AXS / PBAT alloys of Examples 1-22 is shown in Table 1.

[0058] Its preparation method is:

[0059] According to Table 1, AXS resin, PBAT resin, compatibilizer, coupling agent, lubricant, and other auxiliary agents are mixed and added to the main feeding port of the twin-screw extruder, and the hemp fiber is added to the main feed port of the twin-screw extruder. The side feeding port is melted and granulated to obtain a reinforced AXS / PBAT alloy with low temperature impact resistance.

[0060] The feeding speed of the twin-screw extruder is 200-350rpm; the temperature of each section of the twin-screw extruder from the feeding port to the machine head is 120-160°C in the first zone, 170-210°C in the second zone, and 170-210°C in the third zone. 170-210°C, 170-210°C in the fourth zone, 170-210°C in the fifth zone, 190-230°C die temperature, 100-500r / min main machine speed, vacuum degree ≤0.1MPa.

Abstract

The invention discloses a low-temperature impact-resistant enhanced AXS / PBAT alloy and a preparation method and application thereof. The low-temperature impact-resistant enhanced AXS / PBAT alloy is prepared from the following components in parts by weight: 35 to 70 parts of AXS resin, 15 to 45 parts of PBAT resin, 5 to 30 parts of fibrilia, 0.5 to 10 parts of compatilizer, 0.5 to 5 parts of coupling agent, 0.5 to 5 parts of lubricant and 0.1 to 5 parts of other auxiliary agents, the fibrilia is subjected to surface treatment through a solvent, and the solvent is one of alkali liquor, a sodium chlorite solution, an acrylic acid solution or a benzoyl chloride solution. Through the synergistic interaction of the AXS resin, the PBAT resin, the fibrilia and other components, the low-temperature impact resistance is improved on the premise of keeping good rigidity of the AXS / PBAT alloy. The AXS / PBAT alloy can bear the impact of a steel ball with the mass of 1 KG at the temperature of -20 DEG C, and the highest height of the AXS / PBAT alloy without cracks is larger than or equal to 1.25 m. In addition, the AXS / PBAT alloy adopts the degradable PBAT resin and the fibrilia, so that the AXS / PBAT alloy has good biodegradability.

Description

technical field [0001] The invention relates to the field of polymer material modification, and more specifically, to a low-temperature impact-resistant reinforced AXS / PBAT alloy and its preparation method and application. Background technique [0002] Styrene-based resin (AXS resin, including acrylonitrile-butadiene-styrene copolymer, acrylonitrile-chlorinated polyethylene-styrene copolymer, acrylonitrile-EPDM rubber-styrene copolymer) is a strength It is a high-strength, tough and easy-to-process thermoplastic polymer material. Polybutylene adipate terephthalate (PBAT resin) is a biodegradable resin with high toughness. Adding part of PBAT resin to AXS resin, together with compatibilizer, the prepared AXS / PBAT alloy has excellent toughness and fluidity, and has good appearance gloss. [0003] In order to improve the rigidity and dimensional stability of the AXS / PBAT alloy, the AXS / PBAT alloy is usually modified with inorganic fiber reinforcement. However, it has been re...
