Disclosed is a flame-retardant HIPS material and a preparation method thereof, comprising the following components: 79 parts to 91 parts of a HIPS resin; 2 parts to 8 parts of a brominated flame retardant; and 3 parts to 7 parts of an auxiliary flame retardant; wherein the auxiliary flame retardant is a 1,3,5-triazine compound. In the present invention, a synergistic compounding of the brominated flame retardant and the auxiliary flame retardant effectively reduces an amount of the brominated flame retardant, and a stable UL 94 (1.5 mm) V-2 flame-retardant class can be achieved. Compared with the existing brominated flame-retardant HIPS, the present invention has a low halogen content, low gas, high cost performance ratio, relatively good thermal stability, and relatively light corrosiveness to the mold, and can be widely applied in the field of thin-walled parts, such as office equipment, video multimedia, household appliances and the like.

The disclosure provides a novel electronic component that is highly safe against environmental pollution such as air pollution and water pollution, and has high flame retardancy. A relay includes a base, a card and a case molded from a flame-retardant resin composition containing a resin material, a brominated flame retardant, and a bismuth-based flame retardant aid.

A fire prevention coating formula is applied to surfaces in order to reduce and prevent the spread of fires across the applied surfaces. The homogeneous coating mixture is applied to surfaces through spraying or painting means. When heated, the fire prevention coating formula forms a thick, stable, passivating oxide layer protecting the surface from further reaction.

Exemplary embodiments pertain to the art of first suppressants and, in particular, to maintaining a desired and constant blend of multiple fire suppressants during discharge. The present disclosure provides fire extinguisher assemblies utilizing a constant blend ratio of fire suppressant agents during discharge. More particularly, the present disclosure provides fire extinguisher assemblies utilizing a constant blend ratio of a first fire suppressant agent (e.g., a low-boiling, high-volatility agent) and a second fire suppressant agent (e.g., a higher-boiling, lower-volatility agent) during discharge. The embodiments and fire extinguisher assemblies described herein can help keep the pressure constant during discharge of the fire extinguisher assemblies.
