Embodiment 1

[0034] The organic fireproof sealing material of the present invention is uniformly kneaded according to the formula in Table 1 (by mass parts) into a plastic solid with certain flexibility, then weighed and packaged.

[0035] Raw materials and proportioning (parts by mass), refractory performance of the embodiment of table 1

[0036]

[0037] It can be seen from the above table that the fireproof sealing material is composed of various raw materials. The properties of various raw materials are different, and their own fire resistance performance is quite different. However, they play different roles in the fireproof sealing material and cannot be replaced by each other. Therefore, the raw material ratio of the fireproof plugging material has a significant impact on its fire resistance performance. For the eight examples listed in Table 1, due to the different ratios of raw materials, the fire-resistant time of the fireproof plugging materials shows a large difference, the ...

Abstract

The invention belongs to the technical field of fireproof blocking materials and preparation thereof, and particularly relates to an expanded organic fireproof blocking material and a preparation method thereof. The organic fireproof blocking material comprises the following raw materials in parts by mass: 150-220 parts of an inorganic filler, 10-20 parts of high-alumina aluminum silicate cellucotton, 5-14 parts of expanded graphite, 108-130 parts of an organic fireproof adhesive and 8-12 parts of a diluent which are mixed together. The fireproof blocking material has remarkable fireproof and insulating effects, can reach the A3 grade in the GB23864-2009 Fireproof Blocking Material, has favorable physical and chemical properties and superior weatherability, can adapt to various holes, openings, gaps and the like in practical application, facilitates construction, maintenance and replacement, and can effectively prevent flame and smoke on fire scenes from diffusing and spreading through holes and gaps in walls.

Description

technical field [0001] The invention belongs to the technical field of fireproof sealing materials and their preparation, and in particular relates to a kind of material suitable for sealing building penetrating structural cavities, gaps between building components or between fireproof partition components and other components, and plastic pipes passing through walls, floors, etc. Cavity intumescent organic fireproof sealing material and preparation method thereof. [0002] Background technique [0003] my country's "Code for Fire Protection Design of Buildings" and "Code for Fire Protection Design of High-Rise Civil Buildings" stipulate that the openings formed when the penetrations (such as cables, air pipes, etc.) Carry out fire sealing to prevent the spread of fire and the spread of toxic fumes. Organic fireproof sealing material is the most commonly used fireproof sealing material. [0004] At present, the domestically published patent documents on organic fireproof b...
