Abstract

The invention discloses a universal white master batch and a preparation method thereof. The white master batch is prepared from the following raw materials in parts by weight: 30-35 parts of carrierresin, 20-25 parts of titanium dioxide, 1-3 parts of a dispersing agent, 2-5 parts of an antioxidant and 10-15 parts of desilicication powder. The white master batch is good in dispersity, the preparation method is simple and suitable for large-scale production, the desilicication powder is added into the preparation raw materials of the white master batch, and the porous structure on the surfaceof the desilicication powder has relatively high adsorption capacity on the titanium dioxide, so that the titanium dioxide is not prone to falling off, the coloring capacity of the white master batchis high, and the coloring effect is good and lasting; as fired diatomite is ground through a grinding wheel, it is guaranteed that the subsequently-prepared desilicication powder is finer, and accordingly the glossiness and coloring capacity of the white master batch are guaranteed; and a desilicication solution can be rapidly produced through a desilicication solution production device, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of plastic coloring, in particular to a general-purpose white masterbatch and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the plastic industry and the continuous improvement of plastic properties, plastic products have been more widely used. Usually, plastic products need to be matched with colors, and the coloring methods can be divided into three types: toner coloring, dyeing granule coloring and masterbatch coloring. Masterbatches are usually composed of three elements: carrier resin, pigment and additives. Among them, the pigment is the core, and the performance of the pigment plays a decisive role in the performance of the masterbatch. Titanium dioxide has strong hiding power and high whiteness, and is the first choice for white masterbatches; the preparation steps of traditional white masterbatches are complicated and are not suitable for large-scal...
