Problems solved by technology

[0003] However, the fireproof sealing materials currently on the market are usually made of chlorinated paraffin as the main material, which belongs to halogen elements.
This kind of fireproof sealing blockage made of chlorinated paraffin as the main material is easy to produce poisonous gas in case of fire, which not only affects the escape of personnel and the rescue of firefighters, but also has poor sealing performance after construction due to its high density.

Embodiment 1

[0016] According to different vulcanization speeds and physical performance requirements, determine the preparation ratio of the formula and take the value in parts. Silicone rubber (100 parts) is individually packaged as group A material; methyl silicone oil (20 parts) and aluminum hydroxide (20 parts) are mixed and packaged as group B material; tetraethyl orthosilicate (5 parts) and organotin ( 5 parts) are mixed and packaged in plastic bags, and placed in group B of the methyl silicone oil packaging barrel to form a two-component package of A and B.

Embodiment 2

[0018] First, mix the tetraethyl orthosilicate and organotin suspended in the bucket of group B into the material of group B. According to the amount of the hole to be blocked, take the material in groups A and B in proportion, add group A and B into a container and stir quickly, then pour it into the hole to be blocked (the hole to be blocked should be supported and protected first. leak preparation). After 5-30 minutes of initial setting, 24 hours of complete vulcanization.

[0019] When used in large quantities, special mechanical plugging can also be used.

Abstract

The present invention is one kind of halogen-less low density fireproof sealing blocking material for blocking holes and pores. The present invention features that the halogen-less fireproof sealing blocking material is prepared with silicon rubber as cementing material, and through compounding with methyl silicon oil, aluminum hydroxide, ethyl silicate, organic tin and other components via stirring, and sulfurizing. The halogen-less fireproof sealing blocking material has low density, good flowability, good watertight and airtight and no burning produced toxic gas.

Description

1. Technical field [0001] The invention relates to a halogen-free fireproof sealing blockage and a manufacturing process thereof, belonging to the technical field of chemical polymer materials. 2. Background technology [0002] In order to control the spread of fire, cable penetration holes and pipe holes in modern buildings need to be sealed for fire protection. The cable tray boxes of warships, ships, and aircraft need more fireproof sealing. Therefore, the application fields of fireproof sealing materials are very wide. [0003] However, the fireproof sealing materials currently on the market are usually made of chlorinated paraffin as the main material, which belongs to halogen elements. This kind of fireproof sealing blockage made of chlorinated paraffin as the main material is easy to produce poisonous gas in case of fire, which not only affects the escape of personnel and the rescue of firefighters, but also has poor sealing performance after construction due to its...
