Embodiment 1

[0022] Example 1 An expanded graphite flame retardant fire extinguishing board

[0023] The invention provides an expanded graphite flame-retardant fire extinguishing board, which includes UF resin rubber powder and low-temperature expanded graphite, and the weight ratio of the UF resin rubber powder to the low-temperature expanded graphite is 0.5:3.5.

[0024] The low-temperature expanded graphite is selected from 50-mesh or 80-mesh natural flake graphite.

[0025] Among them, the expanded graphite flame-retardant fire extinguishing board prepared according to the ratio in this example is selected. When the temperature reaches 200° C., the expansion ratio can reach 160 times, and when the temperature reaches 500° C., the expansion ratio can reach 250 times.

[0026] Natural flake graphite expands when encountering high temperature to form worms that are not afraid of flames and do not burn. When they fall on the burning fire source, they can instantly extinguish the flame and...

[0027] Example 2 An expanded graphite flame retardant fire extinguishing board

[0028] The invention provides an expanded graphite flame-retardant fire extinguishing board, which includes UF resin rubber powder and low-temperature expanded graphite, and the weight ratio of the UF resin rubber powder to the low-temperature expanded graphite is 1:4.

[0029] The low-temperature expanded graphite is selected from 50-mesh or 80-mesh natural flake graphite.

[0030] Among them, the expanded graphite flame-retardant fire extinguishing board prepared according to the ratio in this example is selected. When the temperature reaches 200°C, the expansion ratio can reach 180 times, and when the temperature reaches 500°C, the expansion ratio can reach 300 times.

[0031] Natural flake graphite expands when encountering high temperature to form worms that are not afraid of flames and do not burn. When they fall on the burning fire source, they can instantly extinguish the flame and play a ...

Abstract

The invention provides an expanded graphite flame-retardant fire-extinguishing plate which comprises UF resin rubber powder and low-temperature expanded graphite, and the weight part ratio of the UF resin rubber powder to the low-temperature expanded graphite is 0.5-1.5: 3.5-4.5. The invention also provides a preparation method of the expanded graphite flame-retardant fire-extinguishing plate. The expanded graphite flame-retardant fire extinguishing plate expands at high temperature to generate worms which are flame-resistant and non-combustible, can instantly extinguish flames when falling on a burning fire source, can resist high temperature of 3000 DEG C without combustion, immediately extinguishes big fire, and plays a role in automatic fire fighting; the application range is wide and the strength is high; in the fire extinguishing process of the fire extinguishing plate, waste water, waste acid and waste alkali are not generated, and no harmful gas overflows.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing boards, in particular to an expanded graphite flame-retardant fire extinguishing board and a preparation method thereof. Background technique [0002] At present, there are several domestic factories producing flame retardant boards with single performance, which can only prevent the fire itself from burning, or slow down the burning, and can only block the direct contact between the fire source and the object, so as to slow down the occurrence of fire in a short time. [0003] The materials they consist of are mostly wood, bamboo, and metal materials, or are coated with refractory materials on their surfaces to achieve fire resistance. However, such materials only have fire resistance, and do not have the ability to block flames and extinguish fires. There is a great fire hazard in the office environment or furniture environment using this material. [0004] In summary, there are obvi...
