Embodiment 1

[0029] Apply 1.5mm thick expandable graphite coating on one side of the 5mm thick EVA foam board at one time to form an expandable graphite coating layer. After 24 hours at room temperature, coat the other side, and the other side is coated with 1.5mm thick expandable graphite coating. The graphite coating also forms an expandable graphite coating layer, and the finished product of the firestopping material is 8mm thick in total. The expandable graphite coating layer can also be coated to the required thickness multiple times, and the surface smoothness of multiple coatings is better than that of one-time coating. The finished product of the fireproof sealing material can be stretched, bent, compressed, punched and cut.

Embodiment 2

[0031] Die a 5mm thick EVA foam board into a sheet with an outer diameter of 120mm and an inner diameter of 100mm, put the sheet into a mold and coat the expandable graphite coating on its four sides to form an expandable graphite coating layer, and obtain an outer diameter of 123mm and an inner diameter of 97mm , 8mm thick fireproof plugging material 2 finished product, the finished fireproof plugging material is set outside the pipe with an outer diameter of 100mm (the penetrating object 1, the penetrating object 1 can be a steel pipe or a cable, etc.), and the hole with an inner diameter of 118mm~123mm ( Formed between the penetrating object 1 and the penetrating object 3, the penetrating object can be a pinch-off wall or floor, etc.) for sealing, such as figure 1 and figure 2 shown.

Embodiment 3

[0033] The finished fireproof sealing material made in Example 1 is punched into a sheet with a thickness of 8 mm, an outer diameter of 123 mm, and an inner diameter of 98 mm. The hole is sealed, such as figure 1 and figure 2 shown.

Abstract

The invention relates to a fire-proof sealing material, comprising at least one expandable graphite coating layer, wherein the expandable graphite coating layer is formed by applying an expandable graphite coating; the expandable graphite coating is prepared from the following raw materials in parts by mass: 0.1-20 parts of expandable graphite, 0.1-20 parts of expandable fire retardant, 0.1-1 part of foaming microspheres and 20 parts of oil-based or water-based emulsion. The preparation method of the fire-proof sealing material is simple, and has the advantages of environmental protection, waterproofness, good porosity compatibility, convenience in construction and long service life.

Description

technical field [0001] The invention relates to a fireproof sealing material and a preparation method thereof, belonging to the field of fireproof materials. Background technique [0002] Cables, oil pipes, air pipes, air pipes, metal pipes and other penetrating objects pass Fireproof sealing of holes formed when building partition walls or interlayers; in the past, refractory bricks, mineral wool, ceramic wool, etc. were used to seal them, due to problems such as environmental protection, water absorption, and construction difficulties. At present, most of them are initially sealed with fireproof bags and then filled with organic blocking materials. However, the size of the hole is different. Although the fireproof package has various sizes and specifications, it is difficult to fully meet the size of the hole, so it is necessary to use organic blockage for further sealing. Since the fireproof woven bag is filled with powdery particles, which can seep and absorb water, it...
