Problems solved by technology

[0003] At present, the shell material of the fire alarm is usually made of ABS resin. Because the flame retardancy of ABS resin is poor, when a fire breaks out, the shell of the fire alarm is very easy to burn, and then the inside of the alarm is burned out, making the alarm The alarm cannot continue to work, people lose the reminder of the alarm, the risk factor is high, and it brings great trouble to the user

Abstract

The invention provides a flame-retarding shell material for a fire alarm device and a preparation method of the shell material and relates to the technical field of fire alarm device production. The fire alarm device is prepared from the following raw materials in parts by weight: 50 to 60 parts of ABS (Acrylonitrile Butadiene Styrene) resin, 15 to 25 parts of polycarbonate, 1 to 2 parts of nano diatomite, 10 to 15 parts of dibromoneopentyl glycol phosphate, 5 to 10 parts of decabromodiphenyl ethane, 5 to 10 parts of aluminum isobutylhypophosphite, 6 to 8 parts of brominated epoxy resin, 2 to4 parts of antimony trioxide, 5 to 7 parts of silicon carbide, 3 to 5 parts of molybdenum disulfide, 2 to 4 parts of zirconium oxide, 0.8 to 1.2 parts of a modifying agent, 1 to 2 parts of a couplingagent and 2 to 3 parts of a dispersing agent. By adopting the flame-retarding shell material, disadvantages in the prior art are overcome; the flame-retarding performance of the shell material for thefire alarm device can be effectively improved, and a condition that a shell cannot work continually after being combusted is prevented; the shell material is high in safety and good in utilization effect; the wear-resisting performance of the shell material also can be effectively improved and the whole performance of the shell material is excellent; the shell material is long in service life andis suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of fire alarm production, in particular to a flame-retardant fire alarm shell material and a preparation method thereof. Background technique [0002] With the increase of fire and electricity consumption in modern households, the frequency of household fires is also increasing. Once a family fire breaks out, unfavorable factors such as untimely fighting, lack of fire extinguishing equipment, panic and slow escape of the people present are likely to occur, which will eventually lead to heavy loss of life and property. Therefore, most families can install fire alarms to remind people that a fire occurs and needs to escape quickly. This has practical significance for preventing family fires and reducing fire losses. [0003] At present, the shell material of the fire alarm is usually made of ABS resin. Because the flame retardancy of ABS resin is poor, when a fire breaks out, the shell of the fire alarm is v...
