Embodiment 1～20

[0054] The content of each component in the ACS / PBAT complexes of Examples 1-20 is shown in Table 1.

[0055] Its preparation method is:

[0056] S1. According to Table 1, dry the PBAT resin at 90°C until the moisture content is ≤0.2%, mix it with the scratch resistance modifier, add it into a twin-screw extruder, melt blend, extrude and granulate to obtain masterbatch ;

[0057] S2. After mixing the masterbatch, ACS resin, nucleating agent, compatibilizer and additives, add them to a twin-screw extruder, melt blend, extrude and granulate to obtain the scratch-resistant ACS / PBAT compound .

[0058]Among them, the temperature of the first to second zones of the twin-screw extruder is 120°C to 170°C, the temperature of the third to fifth zones is 160°C to 180°C, the temperature of the fifth to tenth zones is 170°C to 190°C, and the screw speed is 350rpm to 450rpm;

[0059] The screw combination of the twin-screw extruder is:

[0060] The screw combination in the melting sect...

Abstract

The invention discloses a scratch-resistant ACS / PBAT compound and a preparation method and application thereof. The ACS / PBAT compound comprises the following components: ACS resin, PBAT resin, a compatilizer, a nucleating agent and a scratch-resistant modifier, wherein the scratch-resistant modifier is one or more of fatty acid amide, polytetrafluoroethylene or silicone. Through the mutual synergistic effect of the scratch-resistant modifier, the ACS resin, the PBAT resin, the compatilizer, the nucleating agent and other components, the surface friction coefficient of the ACS / PBAT compound is effectively reduced, and the ACS / PBAT compound with excellent scratch resistance and good glossiness is obtained.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, more specifically, to a scratch-resistant ACS / PBAT compound and its preparation method and application. Background technique [0002] ACS resin is a chlorinated polyethylene rubber toughened acrylonitrile-styrene copolymer, which is similar to the basic physical properties of ABS resin toughened with butadiene rubber, while chlorinated polyethylene rubber does not contain the double bond structure of butadiene, ACS Resin has better weather resistance, chemical resistance and flame retardancy, and can be widely used in household appliances, electronic appliances, garden tools, automobile transportation and other product fields. [0003] Polybutylene adipate terephthalate (PBAT) is one of the most active and market-applied resins in the research of biodegradable plastics. PBAT is a combination of butylene adipate and butylene terephthalate. A copolymer with the characteristics of both...
