Problems solved by technology

The content of this kind of white masterbatch titanium dioxide is more than 40%, which will easily lead to a large proportion of color masterbatch
The color masterbatch is easy to sink during mixing with plastics and post-molding, resulting in uneven color dispersion
At the same time, the price of titanium dioxide is higher, resulting in higher production cost of masterbatch

Abstract

The invention discloses a preparation method of a white masterbatch for antibacterial and high impact polystyrene. The white masterbatch is prepared from the following raw materials in parts by weight: 60 to 70 parts of high impact polystyrene, 6 to 9 parts of titanium dioxide, 3 to 7 parts of trimethylolpropane trimethacrylate, 5 to 9 parts of diisooctyl phenyl phosphite, 1 to 3 parts of monoglyceride, 8 to 12 parts of carbon nanofibres, 5 to 9 parts of glycidyl methacrylate grafted acrylonitrile-butadiene-styrene copolymer, 4 to 12 parts of nano-silver, 14 to 18 parts of styrene-butadiene-styrene, 12 to 17 parts of epoxidized soybean oil, 8 to 20 parts of bamboo charcoal powder, 2 to 5 parts of silane coupling agent, 2 to 8 parts of lithium perchlorate, 3 to 8 parts of 2-hydroxybenzophenone, 1 to 4 parts of aluminate vinegar coupling agent and 5 to 15 parts of ACR. The masterbatch disclosed by the invention has the advantages of good antibacterial property, impact resistance, low processing cost and simple preparation technology; in addition, when the white masterbatch is applied to color a high impact polystyrene product, the white masterbatch has the advantages that color stability is improved and the chromatism is relatively small; besides, the problems of unstable color and relatively great chromatism of the existing high impact polystyrene masterbatch during coloring aresolved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of a white masterbatch for antibacterial and high-impact polystyrene. Background technique [0002] Plastic coloring can be done with toner. Toner coloring is characterized by directly using toner (pigment or dye) to add an appropriate amount of powdered additives to color plastic particles. The advantage is low cost and can be operated in small batches. But its biggest disadvantage is that the pigments will fly during the process of transportation, storage, weighing and mixing, which will cause pollution and seriously affect the working environment. There is also toner coloring. Another headache for users is that the hopper of the extruder is not easy to clean. The masterbatch coloring overcomes the various disadvantages of the toner coloring, so the coloring of the masterbatch is the most commonly used plastic coloring method today. ...
