Special color master batch for blending polystyrene sheets

Abstract

The invention discloses a special color master batch for blending polystyrene sheets, which is prepared by heating, uniformly stirring and mixing a plurality of materials and then extruding and granulating, the plurality of materials comprise the following components in percentage by mass: 60-70% of toughened resin, 20-30% of a coloring agent, 10-15% of a flame retardant, 5-10% of a heat stabilizer, and 4-7% of a dispersing agent. the color master batch has the advantages that injection molding plastic is dyed through the colorant, the colorant can evenly dye the injection molding plastic through the dispersing agent, the high-temperature-resistant temperature of the injection molding plastic can be increased through the flame retardant and the heat stabilizer, a sheet product is not prone to scorching in molding, and the toughening resin can prevent the colorant from diffusing before the color master batch is used.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a special color masterbatch for polystyrene sheet mixing; it is used for injection molding sheet products. 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 toda...

Problems solved by technology

[0003] However, at present, domestic masterbatch products cannot be evenly mixed into injection-molded plastics, resulting in the problem of floating color in injection-molded products, that is, uneven color, especially when used in the production of sheet products, not only floating color situation, and due to the thickness of the sheet product, it is easy to cause the plastic to burn during molding. Therefore, there is an urgent need in the market for a color masterbatch that can modify and evenly dye injection-molded plastics.
