Problems solved by technology

However, the inventor found through actual production that in the production and processing of epoxy powder coatings, uneven mixing often leads to color and color differences, or pigments are agglomerated in the process of pigment mixing, resulting in uneven dispersion of pigments and product color differences. The problem of color and color difference of sub-products with pots occurs (for example, the same kind of blue epoxy powder coating, different types of blue coatings such as sky blue and medium blue in different pots and sub-products, resulting in visible color difference in product coatings), or a small amount The poor mixing and dispersibility of the added accelerator leads to problems such as fluctuations in product performance

Abstract

The invention discloses a thermosetting epoxy resin coloring master batch as well as a preparation process and application thereof. The thermosetting epoxy resin coloring master batch is prepared fromthe following raw materials in parts by mass: 50-70 parts of bisphenol A epoxy resin, 5-20 parts of phenolic aldehyde modified epoxy resin, 1-5 parts of a cyclic phenol curing agent, 5-20 parts of nanoscale pigment toner, 5-20 parts of a nano-filler, 5-10 parts of a toughening agent, 0.5-5 parts of a dispersant, 0.1-1 part of an antioxidant, and 0.5-2 parts of pigment treating agent. The preparation process comprises the following steps: uniformly mixing the raw materials to obtain a mixture, extruding the mixture through a double-screw extruder, and performing crushing to obtain the thermosetting epoxy resin coloring master batch. According to the invention, the colorability and dispersity of an epoxy powder coating can be improved, so that the chromatic aberration generated in the production and processing process of different batches / boiler times of the epoxy powder coating is avoided.

Description

technical field [0001] The invention relates to the technical field of epoxy powder coatings, in particular to a thermosetting epoxy resin coloring masterbatch and its preparation process and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Powder coating is a solid powder synthetic resin coating composed of solid resin and pigments, fillers and additives. The dispersion medium of powder coating is air, not solvent and water. There are two types of powder coatings, thermoplastic and thermosetting. Among them, thermosetting powder coatings use thermosetting synthetic resins as film-forming substances. During the drying process, the resins are first melted and...
