Problems solved by technology

Different from traditional filler masterbatches, the use of low-molecular flammable organic substances such as wax and stearic acid in flame-retardant masterbatches will greatly reduce the flame retardancy of flame-retardant masterbatches, and the absence of lubricants will lead to fluidity of flame-retardant masterbatches. Poor, so there are more defects when used in finished products
This contradiction has long plagued the development of flame retardant masterbatches

Abstract

The invention relates to the field of flame retardant master batches, in particular to a high-fluidity flame retardant master batch and a preparation method thereof. Fire retardant intercalated materials are packaged into an inorganic substance of the two-dimension sheet structure, and then are prepared into the high-fluidity flame retardant master batch by the aid of spherical inorganic particles. Fire retardant is protected through the two-dimension sheet structure so that good stability can be achieved, and the mobility is excellent under the assisting action of the two-dimension sheet structure and the spherical particles. The obtained flame retardant master batch has high fluidity, and the defect that an existing flame retardant master batch uses a lubricating agent like paraffin and thus the flame retardant property is lowered is overcome. When the high-fluidity flame retardant master batch is used for plastic products, good dispersity can be achieved, precipitation of the fire retardant is effectively prevented, and thus the fire resistance, processability and appearance performance of the flame retardant plastic products can all be improved.

Description

technical field [0001] The invention relates to the field of flame retardant masterbatch, in particular to a high fluidity flame retardant masterbatch and a preparation method thereof. Background technique [0002] With the development of my country's economy, the amount of polymer materials such as plastics and rubber has increased rapidly, and flame retardants have become one of the important additives for plastic processing. At present, flame retardants are mainly halogen-containing flame retardants and halogen-free flame retardants. Because the dispersibility and compatibility of flame retardants are quite different from those of plastic rubber, flame retardants are usually prefabricated into flame retardant masterbatches. Its remarkable advantage is that the flame retardant masterbatch can organically combine various flame retardant components to produce a coordinated effect. The flame retardant masterbatch is in the form of large particles, which is just the same siz...
