Embodiment Construction

[0019] The present invention is further explained below in conjunction with the examples, but the examples do not limit the present invention in any form.

[0020] A kind of intumescent fire-proof bag filler formula is made up of the following steps:

[0021] 1. Weigh various filling materials according to their weight percentage;

[0022] 2. Grinding various filling materials into powder;

[0023] 3. Stir the filler evenly in a blender;

[0024] 4. Weigh the filling material according to the specifications of the fireproof bag, put it into a specially treated, durable glass fiber cloth bag, and seal it.

[0025] The following are examples:

[0026]

[0027] Remarks: The unit of fire resistance time is minutes.

Abstract

The invention discloses a prescription of an intumescent filler for a fireproof package. The prescription disclosed by the invention is obtained by mixing the following components in parts by weight: 6-20 parts of char-forming agent, 6-20 parts of char-forming catalyst, 10-30 parts of foaming agent, 10-30 parts of inorganic reinforcement, 6-15 parts of inorganic filling agent and 15-45 parts of intumescent material. The prescription disclosed by the invention combines with inorganic filler and organic filler and uses the advantages thereof; fire-resistant barrier with a certain thickness and a certain strength can be intumesced and rapidly charred in a short time in fire, and heat is absorbed and non-flammable gases are released during intumescing and charring processes, so as to achieve the purposes of resisting fire, isolating head and isolating smoke. The prescription has high application value.

Description

technical field [0001] The invention relates to the technical field of fireproof materials, in particular to an expansion type fireproof package filler formula. Background technique [0002] The present invention is currently applied in electric power, telecommunication, postal service, chemical industry, industrial and mining, enterprise, building, and the plugging of cavities formed when cables, oil pipes, air pipes, air pipes, metal pipes and other penetrating objects pass through partition walls or interlayers. Some fireproof bags are filled with inorganic fireproof putty, and some fireproof bags are filled with organic fireproof putty. Inorganic filling materials are difficult to meet the national first-class standard; organic filling materials are prone to release a large amount of harmful gas during fire prevention, poisoning and suffocating escape personnel. Contents of the invention [0003] The purpose of the present invention is to provide an intumescent fire-p...
