Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to color masterbatch based on a nano microcapsule wrapping technology and a preparation method of the color masterbatch. The invention provides the color masterbatch based on a nano microcapsule wrapping technology and the preparation method of the color masterbatch, aiming at the problem that the temperature sensing sensitivity of thermochromic color masterbatch in the prior art still needs to be improved. The color masterbatch based on the nano microcapsule wrapping technology comprises polypropylene, a heat-conducting additive, microcapsule toner and a nucleating agent. The polypropylene, the heat-conducting additive, the microcapsule toner and the nucleating agent are mixed and then added into a double-screw extruder, and the thermochromic color masterbatch is obtained through extrusion granulation. According to the invention, by adding a certain amount of the heat-conducting additive into the polypropylene main material, the heat-conducting property of the prepared color masterbatch is improved, so that the sensing sensitivity of the microcapsule toner in the color masterbatch to temperature change is improved, namely the temperature sensing sensitivity of the color masterbatch is improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a color masterbatch based on nano-microcapsule encapsulation technology and a preparation method thereof. Background technique [0002] Masterbatch is a new type of special colorant for polymer materials, also known as pigment preparation. Color masterbatches are mainly used in plastics. The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading super-normal pigments in the resin. It can be called a pigment concentrate, so its coloring power is higher than that of the pigment itself. When processing, a small amount of color masterbatch and uncolored resin is mixed to achieve the colored resin or product with the designed pigment concentration. In order to endow plastic products with richer functions, thermochromic masterbatches have appeared in the prior art, that is, color...
