Abstract

The invention belongs to the field of high polymer chemistry and polymers, and particularly relates to a compound masterbatch and a preparation method thereof. The compound masterbatch is prepared from the following components in parts by weight: 20-60 parts of a carrier, 20-40 parts of titanium dioxide, 20-30 parts of titanium yellow, 1-6 parts of iron oxide red, 0.5-3 parts of carbon black, 1-5 parts of a stabilizing agent, 25-55 parts of a plasticizer, 100-200 parts of antimonous oxide, 0.5-4 parts of a lubricating agent and 2-6 parts of nano-calcium carbonate. According to the compound masterbatch, nano-calcium carbonate is added into the compound masterbatch to serve as a dispersing agent, the grain size and specific surface area of nano-calcium carbonate are strictly controlled, and the problem of poor dispersibility of high-content titanium dioxide can be solved; furthermore, the crystal form and the grain size of titanium dioxide are selected, and the proportion of titanium dioxide with different grain sizes is controlled, so that titanium dioxide has higher dispersibility and covering power, and a compound masterbatch with high quality is prepared and is suitable for large-scale application.

Description

technical field [0001] The invention belongs to the field of polymer chemistry and polymers, and in particular relates to a composite color cake and a preparation method thereof. Background technique [0002] The color cake is a mixture of resin and a large amount of pigments or dyes prepared into a high-concentration color. When processing, a small amount of color masterbatch is mixed with uncolored resin to achieve the colored resin or product with the designed pigment concentration. Color cake is widely used in polyvinyl chloride, polyethylene, polypropylene, polystyrene, ABS, nylon, PC, PMMA, PET and other resins to produce colorful fibers, clothing, daily plastics, wires and cables, household Electrical appliances, agricultural films, auto parts, health care equipment and other products. [0003] Chinese patent application CN104004300A discloses a color masterbatch formula, including 75-85% carrier, 5-6% additive, 3-5% dispersant, 2-3% pearl powder, 1-2% pigment, 1-2% ...
