Abstract

The invention relates to an aromatic master batch, especially to a high-concentration polyolefin aromatic master batch and its preparation method. The high-concentration polyolefin aromatic master batch comprises the following components of: carrier resin, essence, an absorbent, a filler and a dispersing agent, wherein the carrier resin contains three resins of LLDPE, EVA and SBS; the absorbent is diatomite; the filler is calcium carbonate; and the dispersing agent is polyethylene wax. The aromatic master batch comprises the components of: by weight, 15-18% of LLDPE, 18-23% of EVA, 3-5% of SBS, 5-20% of essence, 18-23% of diatomite, 10-25% of calcium carbonate and 2-4% of polyethylene wax. The preparation method comprises the following steps of: weighing the materials according to the above ratio; adding the carrier resin, the adsorbent, the filler and the dispersing agent together into a mixing pot; slowly adding essence while stirring at a medium speed; pouring the uniformly-mixed materials into a co-rotating parallel twin-screw extruder for extrusion and controlling temperature parameter of the extrusion technology between 100 DEG C and 120 DEG C; carrying out water bath, cooling and drying by cold air blast, and pelletizing to prepare the high-concentration polyolefin aromatic master batch. The aromatic master batch provided by the invention has advantages of strong compatibility of essence and the carrier resin, high content of essence and lasting fragrance, and is applicable to different production technologies of different plastic products.

Description

technical field [0001] The invention relates to a fragrance masterbatch, in particular to a high-concentration polyolefin fragrance masterbatch and a preparation method thereof. Background technique [0002] At present, the production of flavored plastic products is mainly realized by adding flavor directly or adding flavor masterbatch during the production process. (Polypropylene, PP) is the most important] The functional masterbatch of a certain fragrance of the material is mainly used after soaking oil-absorbing rubber and plastic elastomers (belonging to polyolefin materials). However, the disadvantage of this method is that the fragrance content is low And unstable, the combination of essence and carrier resin is weak, and the essence is easy to ooze and volatilize. There are also fragrance masterbatches processed by extruder forced mixing, such as CN1800259A disclosed fragrance masterbatch for plastics and its preparation method, the ingredients include essence, addit...
