Abstract

The invention discloses a hole plugging material and a preparation method thereof, and belongs to the technical field of substation equipment plugging, the hole plugging material is prepared from thefollowing raw materials by weight: 25-35 parts of a binder, 10-15 parts of polymethyl acrylate, 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 a filler, 4-8 parts of an auxiliary agent, and 30-40 parts of ethyl acetate. According to the present invention, the good comprehensive performances are provided, wherein the test results showthat the sample does not crack or pulverize after the damp-heat resistance test; the fire-resistant grade is grade 3, the flame-retardant and fire-resistant performance is excellent, and the fire-resistant effect is good; according to a water resistance test, the material can be soaked for 4.5-5 days, and the surface of the material is complete and does not swell or crack; the freeze-thaw resistance is cyclically tested for 18-20 times, and the surface of the sample is not cracked or pulverized.

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 pass through a section of explosion and fire hazard areas to be laid to normal areas. Cables are flammable objects. Once the cables catch fire and explode, they will spread to other areas and cause fires. Fire-retardant cables should be used for cables entering residential areas or centralized laying. When cables are installed in cable wells, fire-proof sealing should be done to prevent dust and animals from entering the control box or control room or flame spreading through holes when a fire occurs. In the prior art, plugging materials are generally used to seal cable holes. Commonly used plugging materials include organic plugging materials, inorganic plugging ...
