Smell removing master batch as well as preparation method and application thereof

Abstract

The invention discloses a smell removing master batch, as well as a preparation method and an application thereof. The smell removing master batch is prepared by using a porous polymer bead to adsorb a stripping agent, wherein the mass content of the porous polymer bead in the smell removing master batch is 2-50% and the balance is the stripping agent; and the aperture ratio of the porous polymer bead is greater than 50% and the foaming ratio is 2-45 times. The smell removing master batch prepared by the invention has an obvious effect for removing the VOC and the smell in a modified plastic or a modified elastomer, and greater than 80% of the VOC content can be reduced; besides, the smell removing master batch prepared by the invention is added to a high polymer material similar to the porous polymer bead matrix component to modify, the heterogeneous substance is not introduced so that the smell removing master batch does not have negative effects on the physical property, the appearance and the photo-thermal aging characteristic of the high polymer material.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a deodorizing masterbatch and its preparation method and application. Background technique [0002] In order to meet different characteristic requirements and increase product stability, additives are used in the synthesis and modification of plastics, but these additives contain volatile organic compounds (VOC for short), which are the main cause of plastic odor. In addition, small molecular organic compounds produced by thermal degradation of plastics and additives during processing are also another source of VOC. [0003] VOC has a huge impact on human health. When VOC in a confined space reaches a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short period of time. Kidneys, brain and nervous system, causing serious consequences such as memory loss, and even cancer. [0004] In order to reduce the content of volatile organic compounds...
