Embodiment 1

[0024] Weigh each composition according to the following ratio:

[0025]

[0026] First take the resin (liquid carbon nine petroleum resin), additives (methyl silicone oil), tackifier (rosin) and mix and stir for 20 minutes to prepare the bonding resin; then the filler (kaolin and red clay), flame retardant (zinc borate and Antimony dioxide), anticracking fiber (aluminum silicate wool) were mixed and stirred for 30 minutes to obtain a mixed powder; the prepared bonding resin and mixed powder were added to a kneader and kneaded for 30 minutes; the kneaded The plastic solid is put into an extruder for extrusion molding, and the fireproof plugging material is obtained.

Embodiment 2

[0028] Weigh each composition according to the following ratio:

[0029]

[0030] The preparation method of this embodiment is the same as that described in Example 1.

Embodiment 3

[0032] Weigh each composition according to the following ratio:

[0033]

[0034] The preparation method of this embodiment is the same as that described in Example 1.

[0035] According to the detection standard of fireproof sealing material: GB23864-2009 detects the fireproofness obtained by the present invention

Abstract

The invention discloses a fireproofing sealing material, which comprises compositions by weight of: 21-31% of resin, 42-58% of stuffing, 13-18% of fire retardant, 1-3% of assistant, 2-5% of anti-crack fibers and 1-5% of tackifier, wherein the sum of weight percentages of the compositions is 100%. The fireproofing sealing material not only has good fire resistance, flame retardance, corrosion resistance, water resistance, oil resistance, humidity resistance, frost crack resistance and the like and has the advantages of being free of halogen and sulphur and environment-friendly.

Description

technical field [0001] The invention relates to a halogen-free and sulfur-free fireproof sealing material, which belongs to the technical field of sealing materials. Background technique [0002] The traditional organic fireproof sealing materials currently used are mainly made of chlorinated paraffin as the main bonding material and sulfur-containing inorganic materials. These materials will release a large amount of smoke and hydrogen halide gas when a fire occurs, and produce sulfur dioxide at the same time. etc., will cause harm to the human body and the environment. Now there is also a halogen-free organic fireproof blocking material proposed by an invention patent. It has been verified that this material has poor water resistance, and its fireproof performance and physical and chemical properties are difficult to meet the requirements of GB 23864-2009 "Fireproof Blocking Materials". Therefore, it is necessary to explore a halogen-free and sulfur-free fireproof sealing...
