Colored flame retardant masterbatch is a functional additive that adds colorants to masterbatch with flame retardant function to present various colors. Here are some introductions about colored flame-retardant masterbatch:
1. Composition :
-Flame retardant component: This is the core part of the colored flame retardant masterbatch, which determines its flame retardant performance. Common flame retardant ingredients include halogen based (such as bromine based), phosphorus based, nitrogen based, and inorganic flame retardants. For example, bromine based flame retardants have high flame retardant efficiency and good affinity with plastics; Phosphorus based flame retardants have high flame retardant efficiency in certain resins, but they have disadvantages such as difficult color coordination and poor compatibility; Inorganic flame retardants such as magnesium hydroxide have good environmental friendliness, but their dosage is high and their compatibility with organic compounds is poor.
-Colorant: Used to give a specific color to the masterbatch. Colorants are divided into organic pigments and inorganic pigments. Organic pigments have bright colors and complete chromatograms, but their heat and light resistance may be relatively poor; Inorganic pigments have good heat and light resistance, but their colors are relatively dark. Common organic pigments include phthalocyanine red, phthalocyanine blue, etc; Inorganic pigments include cadmium red, cadmium yellow, titanium dioxide, iron oxide red, iron oxide yellow, etc.
-Carrier: It is the matrix of the masterbatch, usually selected as the carrier with the same or well compatible resin as the applied plastic resin, in order to facilitate the uniform dispersion of the masterbatch in the plastic.
- Additives : such as dispersants, lubricants, etc., help improve the processing performance of masterbatch and its dispersibility in plastics.
2. Performance Characteristics :
-Flame retardant performance: It can effectively improve the flame retardant level of materials such as plastics and rubber, delay or prevent the combustion of materials, reduce the speed of flame propagation, and decrease the heat and smoke release during the combustion process.
-Coloring performance: Various colors can be adjusted according to customer needs to meet the color requirements of different products. The colors are uniform, stable, and not easily faded or discolored.
-Good dispersibility: It can be uniformly dispersed in plastic, ensuring the flame retardancy and color uniformity of the material, and avoiding adverse phenomena such as spots, patterns, and delamination.
- Low impact on material properties : Adding a suitable amount of colored flame-retardant masterbatch has a minimal effect on the mechanical and electrical properties of materials such as plastics and rubber, and can maintain the basic properties of the material.
3. Application Fields :
-In the field of electronic appliances, it is used to manufacture components such as casings, wires and cables, sockets, etc. for electronic devices. The materials are required to have good flame retardant properties to prevent short circuits and other faults from causing fires, and to meet different color requirements to achieve product appearance design.
- Automotive field : Applied to automotive interior and exterior parts, engine peripheral components, such as car center console, electrical components, oil storage tanks, etc. Colored flame retardant masterbatch can enable these components to have flame retardant function while meeting the color and appearance requirements of the automotive industry.
-In the field of architecture, it can be used to produce building materials such as plastic pipes, panels, decorative materials, etc., providing fire safety protection for buildings while offering a wide range of color choices.
-Textile field: In some special functional textiles, such as flame-retardant curtains, carpets, protective clothing, etc., colored flame-retardant masterbatch can give textiles flame-retardant function and specific colors.
4. Production process :
Usually, flame retardants, colorants, carriers, and additives are mixed in a certain proportion, and then processed through twin-screw or three screw extruders for mixing, extrusion, granulation, and other process steps. In the production process, it is necessary to strictly control the proportion of each component and processing parameters to ensure the performance and quality of the masterbatch.
