[0030] 1. Preparation of odor remover:

[0031] Odor remover 1#: Stir and react 5kg of β-CD and 5kg of PY88 at 120°C for 2 hours, cool to room temperature, and granulate to obtain the odor remover;

[0032] Odor remover 2#: Stir and react 3kg of β-CD and 7kg of PY88 at 80°C for 5 hours, cool to room temperature, and granulate to obtain the odor remover;

[0033] Odor remover 3#: 7 kg of β-CD and 3 kg of PY88 were stirred and reacted at 150° C. for 1 hour, cooled to room temperature, and granulated to obtain an odor remover.

[0034] 2. Preparation of polyolefin plastics

[0035] Take each raw material according to the weight of Table 1 and Table 2; Under normal temperature and pressure, the above-mentioned raw materials are mixed uniformly in a high-speed mixer; 350 revolutions per minute, the extrusion temperature is 180° C., and PE plastics and PP plastics are prepared.

Abstract

The invention provides an undesirable odor removing agent and a preparation method thereof, polyolefin plastic with low undesirable odor and a preparation method thereof. The undesirable odor removing agent is prepared from the following components in percentage by mass: 30 percent to 70 percent of cyclodextrin and 70 percent to 30 parts of zinc diricinoleate; the method for preparing the undesirable odor removing agent comprises the following steps: weighing the cyclodextrin and the zinc diricinoleate; uniformly mixing and reacting at 80 DEG C to 150 DEG C for 1h to 5h; cooling to room temperature and granulating. The polyolefin plastic with the low undesirable odor is prepared from the following components in parts by weight: 85 to 99 parts of polyolefin resin and 0.01 to 2 parts of the undesirable odor removing agent; the method for preparing the polyolefin plastic with the low undesirable odor comprises the following steps: weighing all the raw materials; uniformly mixing; melting and mixing at proper temperature and extruding and granulating. According to the undesirable odor removing agent provided by the invention, the undesirable odor can be remarkably reduced; when the undesirable odor removing agent is used for preparing plastic, the plastic with the low undesirable odor can be obtained and the original mechanical performance of the plastic is kept.

Description

technical field [0001] The present application relates to, but is not limited to, an odor remover and a preparation method thereof, and a low-odor polyolefin plastic prepared by using the odor remover and a preparation method thereof. Background technique [0002] Polyolefin plastics (polyethylene PE, polypropylene PP) are low in price, excellent in material performance, good in electrical insulation and chemical stability, and at the same time have the advantages of easy processing. They are widely used in packaging fields such as industry, agriculture, and hygiene. At present, it is a kind of polymer material with large output and wide application. Among them, the daily chemical industry uses HDPE or PP resin to produce packaging bottles for laundry detergent, shampoo, and detergent. Catalysts, such as Ziegler-Natta catalysts, chromium-based catalysts, metallocene catalysts, etc. need to be added during the production of polyolefins, and the obtained resin products will c...
