The invention relates to the technical field of organic polymer materials, in particular to a polyolefin high-concentration plasticizer master batch and a preparation method and application thereof. The preparation raw materials of the plasticizer master batch comprise a foamed polyolefin carrier and a plasticizer; the plasticizer is a liquid hydrocarbon having a weight average molecular weight of 500-8000 as determined by a gel permeation chromatography. The invention adopts the self-made foaming polyolefin carrier, has a network structure formed by interconnected holes and higher porosity, can fully adsorb the plasticizer, thereby preparing the plasticizer master batch with high concentration, has small addition amount in the high polymer material, is uniformly dispersed, does not influence the performance of the high polymer material, can improve the physical property of the high polymer material, and ensures that the high polymer material keeps excellent physical and mechanical properties, and the preparation method has simple process, low cost and easy operation. |
