Abstract

The invention discloses a high-gloss colorful pearlescent PET master batch. The high-gloss colorful pearlescent PET master batch comprises, by weight, 75-85 parts of PET, 8-15 parts of PMMA, 3-8 partsof a toner, 0.2-3 parts of a scraping resistant agent and 0.1-0.5 part of a lubricant. A preparation method of the high-gloss colorful pearlescent PET master batch comprises the following steps: rawmaterials are weighed according to above weight part proportions, are added into a high-speed mixer, and are uniformly stirred, the obtained mixture is added into a homodromous double screw extruder,and is blended, extruded and drawn, the obtained mixture is pelletized to obtain a preliminary master batch, and the preliminary master batch is dried to obtain the finished master batch. Compared with the prior art, the preparation method prepares the high-gloss colorful pearlescent PET master batch with a face pearl-like gloss without adding pearl powder; and he pearlescent master batch has theadvantages of good dispersibility and tinting strength, dust-free and environmentally-friendly processing and using process, simple manufacturing technology, low production cost and wide uses.

Description

technical field [0001] The invention relates to a masterbatch and a preparation method thereof, in particular to a high-gloss illusion pearlescent PET masterbatch and a preparation method thereof. Background technique [0002] Pearlescent powder is a kind of toner. In the production process of toner, the final process is generally made into finished products through filtration, drying, and crushing. However, when the toner is exposed to high temperature during the drying process, it is easy to reunite the pigment molecules. Thereby causing problems such as not easy to disperse, quality decline and complicated processing technology in subsequent use. [0003] Pearlescent effect is due to TiO 2 Or other metal oxides are coated on the substrate, and the light is reflected by multiple parallels to form a pearly luster. In order to achieve a good pearlescent effect, the amount of pearlescent powder added is large, about 20-40%, and the surface of the pearlescent powder is a met...
