Abstract

The invention aims to provide a special color masterbatch material for flame-retardant polystyrene (PS) as well as a preparation method of the special color masterbatch material. At present, the PS isone of five kinds of universal plastic, has high mechanical property, electric insulation property and processability, is stable in size stability and easy in coloring, and is widely applied to various industries of electric appliance decoration, buildings, traffic, military project and the like. However, the PS is as same as most of polymers, is ignited once being contacted with flame, still canbe combusted after a fire source is removed, has large heat release quantity and large smoke generating quantity, and can release toxic gas. Therefore, when the PS is used for manufacturing productswith requirements on fireproof safety, flame-retardant treatment must be conducted. The mechanical property of the color masterbatch material special for flame-retardant polystyrene is obviously improved, the production method is simple and convenient, the materials are easily available, the cost is low and pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of polystyrene material production and aims to improve the original deficiencies of polystyrene. Produce products that meet social needs. Background technique [0002] Polystyrene, English name: polystyrene, abbreviated name PS. Its chemical formula is: C6H5. [0003] At present, polystyrene (PS) is one of the five general-purpose plastics. It has good mechanical properties, electrical insulation properties and processing properties, and has good dimensional stability and easy coloring. It is widely used in electrical decoration, construction, transportation, military industry, etc. among various industries. However, like most polymers, PS is ignited once it comes into contact with flame, and can still burn after removing the fire source, with large heat release, large amount of smoke, and release of toxic gases. Therefore, when PS is used in the manufacture of products requiring fire safety, flame retar...
