Abstract

The invention discloses a VOC-decreased master batch for polypropylene as well as a preparation method and application of the VOC-decreased master batch. The VOC-decreased master batch is prepared from a novel microcellular-foamed polypropylene carrier, an aqueous solution VOC remover adsorbed to the polypropylene carrier and a surfactant in parts by mass. According to the application, in a preparation process of a composite material, the VOC-decreased master batch and polypropylene resin are uniformly mixed and stirred by virtue of a VC efficient mixer, and the mixture is extruded and granulated by virtue of twin-screw extrusion to generate an environment-friendly modified polypropylene composite material; the addition amount of the VOC-decreased master batch is 1%-10%. The VOC-decreased master batch for polypropylene has good compatibility with the polypropylene resin and can be completely devolatilized in a vacuum manner without residues, so that the subsequent processing and performance of modified polypropylene are not influenced, VOC of a polypropylene product is effectively decreased, and the polypropylene product is relatively environmentally friendly and can meet requirements of automobile manufacturers on VOC.

Description

technical field [0001] The invention relates to polypropylene modification, in particular to a VOC-reducing masterbatch used for polypropylene modified materials, and a preparation method and application of the VOC-reducing masterbatch, belonging to the field of polymer composite materials. Background technique [0002] Polypropylene is a semi-crystalline thermoplastic with excellent mechanical properties, corrosion resistance and low price, and is widely used in the automotive field. However, polypropylene will release volatile organic compounds (VOC) to varying degrees during processing and use, and there are problems such as polluting the environment and endangering human health. The "Guidelines for Air Quality Evaluation in Passenger Cars" (GB / T27630) was officially implemented on March 1, 2012, and was officially included in the government's basic requirements for environmentally friendly vehicles on April 24, 2014. At present, the Ministry of Environmental Protection ...
