Problems solved by technology

[0002] Existing polyester waste bottle flakes (i.e. polyethylene terephthalate, PET) are generally used for weaving or alone for blowing low-end products such as daily-use packaging bottles, polypropylene waste injection molding (PP) They are also processed into low-end products such as daily-use packaging bags and packaging bottles by means of separate recycling. This kind of extensive recycling has simple processing, poor quality, and low utilization value.

Embodiment 1

[0021] In this embodiment, a high-strength injection molding material is prepared by using polyester waste bottle flakes and polypropylene waste injection molding material. The high-strength injection molding material is prepared from the following raw materials in parts by weight: PET / PP mixed waste 100 parts, 7 parts of chlorinated polyethylene, 0.8 part of maleic anhydride, 0.5 part of silane coupling agent, 2 parts of paraffin oil, 0.5 part of ferrous sulfate, wherein, the PET / PP mixed waste is made of 10wt% polyester waste It is composed of bottle flakes (PET) and 90wt% polypropylene waste injection plastic (PP).

[0022] The above-mentioned high-strength injection plastic prepared by using polyester waste bottle flakes and polypropylene waste injection plastic is prepared by the following method, including the following steps:

[0023] (1) Separately crush polyester waste bottle flakes (PET) and polypropylene waste injection molding plastics (PP) into materials of simila...

Embodiment 2

[0027] In this embodiment, a high-strength injection molding material is prepared by using waste polyester bottle flakes and waste polypropylene injection molding material. The high-strength injection molding material is prepared from the following raw materials in parts by weight: PET / PP mixed waste 100 7 parts, 7 parts of chlorinated polyethylene, 0.6 part of maleic anhydride, 0.7 part of silane coupling agent, 1.5 parts of paraffin oil, 0.5 part of ferrous sulfate, wherein, the PET / PP mixed waste is made of 20wt% polyester waste bottle Sheet (PET) and 80wt% polypropylene waste injection plastic (PP).

[0028] The method adopted in this embodiment to prepare the above-mentioned high-strength injection molding compound is the same as that in Embodiment 1.

Embodiment 3

[0030] In this embodiment, a high-strength injection molding material is prepared by using polyester waste bottle flakes and polypropylene waste injection molding material. The high-strength injection molding material is prepared from the following raw materials in parts by weight: PET / PP mixed waste 100 parts, 6 parts of chlorinated polyethylene, 0.8 part of maleic anhydride, 0.5 part of silane coupling agent, 2 parts of paraffin oil, 0.5 part of ferrous sulfate, wherein, the PET / PP mixed waste is made of 30wt% polyester waste It is composed of bottle flakes (PET) and 70wt% polypropylene waste injection plastic (PP).

[0031] The method adopted in this embodiment to prepare the above-mentioned high-strength injection molding compound is the same as that in Embodiment 1.

Abstract

The invention relates to a high-strength injection molding material prepared from waste polyester bottle flakes and waste polypropylene injection molding materials and a preparation method thereof, and belongs to the technical field of treatment and resource utilization of waste plastics. The method includes: firstly, crushing the waste polyester bottle flakes (PET) and the waste polypropylene injection molding materials (PP) into materials similar in size, washing and drying prior to uniform mixing to obtain the PET / PP mixed waste; secondly, taking 100 parts of the prepared PET / PP mixed waste, 5-10 parts of chlorinated polyethylene, 0.5-1 part of maleic anhydride, 0.5-1 part of silane coupling agent, 1-3 parts of paroline oil and 0.5 part of ferrous sulfate for blending prior to extruding and granulating to prepare the high-strength injection molding material.The prepared injection molding material is superior to brand-new PP-V30G injection molding material in impact strength, and undesirable odor emitted from the waste plastics are effectively reduced and lowered during processing as the ferrous sulfate which can be in chemical combination with odor of the waste polyester bottle flakes and the polypropylene film waste is contained in the raw material formula.
