preparation example Construction

[0038] The present invention further provides a method for preparing a waste ABS / HIPS blended modified material, comprising the following steps:

[0039] 1. the rubber, organic peroxide, and ZDMA are prepared by melt blending a rubber elastomer;

[0040] ② Melt blending of waste ABS, waste HIPS and rubber elastomers to prepare waste ABS / HIPS blended modified materials.

[0041] The present invention has no special limitation on the equipment used in the melt blending of rubber, organic peroxide, and ZDMA in step ①, preferably an internal mixer well known to those skilled in the art. The melt blending temperature in step ① is 160-170°C. The rotational speed of the internal mixer is preferably 40r / min.

[0042] The present invention has no special limitation on the equipment used in the melt blending of waste ABS, waste HIPS and rubber elastic body in step ②, preferably a micro twin-screw extruder well known to those skilled in the art. The melt blending temperature in step ②...

Embodiment 1

[0049] First put 100g of nitrile rubber powder and 30g of ZDMA into the internal mixer for melting and blending, then add 1g of DCP to prepare the rubber elastic body, set the temperature of the internal mixer to 170°C; the speed of the internal mixer is 40 r / min. The waste ABS / HIPS is crushed into a particle size of 5-15mm, and then the waste ABS / HIPS is placed in a vacuum drying oven for 8 hours at a drying temperature of 80°C. After mixing 20g of waste ABS / HIPS (ABS:HIPS=7:3) and 0.4g of rubber elastomer, add it to the micro-twin-screw extruder, and set the temperature of the micro-twin-screw extruder from one section to the head They are 210°C, 220°C, 230°C, and 220°C, respectively. The screw speed of the micro-twin-screw extruder was 35 r / min. The material is granulated by melt extrusion, and the obtained pellets of the waste ABS / HIPS modified material are placed in a vacuum drying oven, dried for 8 hours, and the drying temperature is 80°C; the dried pellets are added...

Abstract

The invention belongs to the field of high polymer materials, and particularly relates to an ion crosslinking modified regenerated ABS / HIPS blending material and a preparation method thereof. The waste ABS / HIPS blending modified material provided by the invention is prepared by a melt blending method and comprises the following materials in parts by weight: 70 parts of ABS for waste household appliances, 30 parts of HIPS for waste household appliances, 0-10 parts of rubber, 0-0.2 parts of organic peroxide, and 0-4 parts of ZDMA. Experimental results show that the tensile strength of the wasteABS / HIPS blending modified material provided by the invention is basically about 28MPa, the notch impact strength is higher than 2.5 kJ / m<2>, and the melt mass flow rate is higher than 10g / 10min. Thepreparation method provided by the invention solves the problem that the waste ABS / HIPS material is poor in mechanical property and difficult to reutilize due to poor compatibility.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and in particular relates to a regeneration ABS / HIPS blend material modified by ion crosslinking and a preparation method thereof. Background technique [0002] With the advancement of science and technology, plastics have been widely used in electronics and electrical products; and due to technological and industrial innovations, the development and upgrading of the electronic product industry and market have been accelerated. At the same time, a large amount of electronic and electrical waste is produced, and the disposal of these discarded electronic and electrical waste and the harm to the environment have gradually become problems that cannot be ignored. [0003] Regarding the disposal of waste plastics, extensive landfilling and incineration of waste plastics will not only cause secondary pollution to the environment, but also this treatment method does not conform to the current con...
