Abstract

The invention discloses a hole plugging material and a preparation method thereof, belonging to the technical field of plugging of substation equipment. 1.5-2.5 parts of polyvinylidene fluoride, 5-10 parts of alumina fiber, 2-3 parts of ramie fiber, 4.5-9 parts of filler, 4-8 parts of auxiliary, 30-40 parts of ethyl acetate. The invention shows good comprehensive performance: in the test of moisture and heat resistance, the sample does not crack or pulverize; the fire resistance level is 3, which has excellent flame retardant, fire resistance and good fire resistance; water resistance test, it can soak 4.5- After 5 days, the surface of the material is complete, not swollen, not cracked; the freeze-thaw resistance performance cycle test, tested 18-20 times, the surface of the sample is not cracked, not powdered.

Description

technical field [0001] The invention relates to the technical field of plugging of substation equipment, in particular to a hole plugging material and a preparation method thereof. Background technique [0002] Power plants, substations, and industrial and mining enterprises use a large number of power cables, and many cables will be laid to normal areas through a section of explosion and fire danger areas. Cables are flammable objects. Once the cables catch fire and explode, they will spread to other areas and cause fires. When cables enter residential areas or are laid in a centralized manner, flame-retardant cables should be used. When cables are installed in cable wells, fire blocking work should be done to prevent dust and animals from entering the control box, control room or the spread of flames through holes in the event of a fire. In the prior art, plugging materials are generally used to seal cable holes. Commonly used plugging materials include organic plugging ma...
