Embodiment 1

[0036] Weigh the raw materials of each component according to the formula: 90 parts by weight of expanded vermiculite, 20 parts by weight of acrylic emulsion, 30 parts by weight of expanded graphite, and 5 parts by weight of zinc oxide; stir to make the above materials uniformly mixed; put the uniformly mixed materials into the mold Compression molding; the compressed molding module is naturally dried at room temperature, and after drying, it becomes the fireproof blocking module.

Embodiment 2

[0038] Weigh the raw materials of each component according to the formula: 80 parts by weight of expanded vermiculite, 30 parts by weight of acrylic emulsion, 20 parts by weight of expanded graphite, and 10 parts by weight of zinc oxide; stir to make the above materials uniformly mixed; put the uniformly mixed materials into the mold Compression molding; the compressed molding module is naturally dried at room temperature, and after drying, it becomes the fireproof blocking module.

Embodiment 3

[0040] Weigh the raw materials of each component according to the formula: 60 parts by weight of expanded vermiculite, 50 parts by weight of acrylic emulsion, 15 parts by weight of expanded graphite, and 20 parts by weight of zinc oxide; stir to make the above materials uniformly mixed; put the uniformly mixed materials into the mold Compression molding; the compressed molding module is naturally dried at room temperature, and after drying, it becomes the fireproof blocking module.

Abstract

The invention discloses a fireproof plugging module, which consists of 40 to 90 weight parts of expanded vermiculite, 10 to 60 weight parts of acrylic acid emulsion, 5 to 30 weight parts of expanded graphite and 5 to 30 weight parts of zinc oxide. The fireproof plugging module has high plasticity and is convenient for opening a hole and cutting; the water resistance, oil resistance, alkaline resistance and other performances of the fireproof plugging module are high, and drawbacks of swelling, deformation and cracking are avoided; the weight is light, the actual density is 0.8g / cm<3>, and the load of a plugging material on a cable bridge frame and a building can be reduced effectively; the fireproof time is long and is increased to more than 5 hours, so the module is a product with national grade one fireproof product; toxic gases are not generated upon contact with fire, halogen components are avoided, and as toxic gases are not released upon contact with fire, the module is environment-friendly; the effective period of the module is long and can reach more than 15 years, so repeated investment and construction are avoided; and the module can be widely used as wire, cable and electric fireproof plug in large industrial and mining enterprises such as power plants, petrochemical enterprises, metallurgical steel enterprises, communication emprises and national defense enterprises.

Description

Technical field [0001] The invention relates to a plugging module, in particular to a fireproof plugging module suitable for larger penetrating openings, and belongs to the technical field of building materials. Background technique [0002] In today's buildings, due to the requirements for laying wires and cables, many penetrating holes are opened between the walls and the floor to facilitate the passage of wires and cables. However, these holes also have potential fire hazards: on the one hand, flames and smoke are easily spread through the holes to the adjacent space; on the other hand, the cable channel may form a shaft effect and accelerate the spread of fire. [0003] At present, fireproof plugging materials are used at home and abroad to seal the holes to effectively prevent the flame from spreading through the holes. However, the existing plugging materials have defects such as poor plasticity, inconvenient disassembly, easy collapse, corrosion to cables, and toxic gases w...
