Embodiment 1～18

[0048] The content of each component in the enhanced AES composition of Examples 1-18 is shown in Table 1.

[0049] Its preparation method is: according to Table 1, mix each component except glass fiber evenly and then add it to the main feeding port of the twin-screw extruder, add the glass fiber to the side feeding port of the twin-screw extruder, melt and co- Mixing, extruding and granulating to obtain enhanced AES composition.

[0050] Among them, the feeding speed of the twin-screw extruder is 200-350rpm; the screw temperature from the feeding port to the machine head is 220-250°C in the first zone, 220-240°C in the second zone, 210-220°C in the third zone, and 210-210℃ in the fourth zone. 230°C, five zones 210-230°C, die temperature 220-230°C, host speed 100-500r / min, vacuum degree ≤0.1MPa.

Abstract

The invention discloses an enhanced AES composition for an outdoor sound equipment shell and a preparation method and application thereof. The reinforced AES composition comprises the following components in parts by weight: 40-60 parts of AES resin, 40-50 parts of PBAT resin, 5-30 parts of glass fibers, 0.5-10 parts of a compatilizer, 0.1-5 parts of a coupling agent, 0.1-5 parts of a lubricant and 0-5 parts of an antioxidant, the melt flow rate of the AES resin under the conditions of 220 DEG C and 10 kg is 20-35 g / 10 min, and the intrinsic viscosity of the PBAT resin is 2.0-2.8 dl / g. The enhanced AES composition for the outdoor sound equipment shell is developed by selecting the AES resin with the specific solution flow rate and the PBAT resin with the intrinsic viscosity and mutual cooperation and synergistic interaction of the glass fibers, the compatilizer, the coupling agent and other components, has excellent toughness and is not prone to brittle rupture, and the anti-falling performance of the enhanced AES material is greatly improved; the enhanced AES composition also has appropriate rigidity, and the prepared AES product can provide a high-quality sound quality effect for the sound equipment as a shell of the outdoor sound equipment.

Description

technical field [0001] The invention relates to the field of modification of polymer materials, and more specifically, relates to a reinforced AES composition for outdoor audio housings and its preparation method and application. Background technique [0002] AES resins are ethylene-propylene-diene monomer (EPDM)-acrylonitrile-styrene copolymers with substantially similar physical properties to butadiene rubber-toughened ABS resins. Since the molecular chain of EPDM is mainly composed of ethylene, propylene and a small amount of non-conjugated diene, with very little double bond content, AES resin has better weather resistance and chemical resistance than ABS resin, and is widely used in outdoor audio, household appliances, Electronic appliances and other product fields. [0003] Since AES is usually reinforced and modified with glass fibers, the addition of glass fibers will greatly reduce the toughness of AES materials on the one hand, for example, 20wt.% glass fibers wil...
