Weatherproof fireproof jam material and preparation method thereof

Abstract

The invention discloses a weatherproof fireproof jam material and a preparation method thereof, and the weatherproof fireproof jam material comprises the following raw materials by weight: 30-35 parts of diethylsilicone oil, 20-35 parts of silicon-acrylate emulsion, 10-15 parts of bauxite, 5-10 parts of zircon sand, 5-10 parts of carbon black powder, 20-30 parts of aluminum hydroxide, 1-3 parts of iron oxide red, 20-30 parts of magnesium oxide, 5-10 parts of pearlite, 4-6 parts of silica aerogel, 5-8 parts of sodium lignosulphonate, 0.5-1.0 part of dioctyl phthalate, 0.5-3.5 parts of titanate coupling agent, and 3-5 parts of polyester fiber. The weatherproof fireproof jam material does not contain halogens, no harmful gas is emitted in the use process, human body damage caused by toxic halogen hydride gases diffusion and electric equipment corrosion caused by halogen acid can be avoided, and the weatherproof fireproof jam material has the advantages of excellent heat insulating fire refractory property, good weathering resistance, good low temperature crack resistance, good water resistance moisture resistance, resistance to acid and alkali corrosion, and the good sealing performance, and the like, and can be adapted to cracks formed due to seasonal changes, environmental temperature changes, rainwater damp and the like.

Description

technical field [0001] The invention relates to the technical field of fire-fighting products, in particular to a weather-resistant fire-proof blocking material and a preparation method thereof. Background technique [0002] Fireproof blockage is used to block various penetrations, such as various openings formed when cables, air pipes, oil pipes, and air pipes pass through walls and floors, and fireproof separation of cable bridges, so as to prevent fire from spreading through these openings and gaps. The current traditional fireproof blockage is mainly obtained by adding halogen flame retardants to obtain excellent flame retardancy. Although halogen materials have good flame retardancy, when a fire occurs, a large amount of smoke and hydrogen halide gas will be released. These smoke and hydrogen halide gas can irritate the human eyes and respiratory system, causing symptoms such as dizziness, coma, dyspnea, suffocation and death. Moreover, there are often free halogens in ...

Problems solved by technology

The current traditional fireproof blockage is mainly obtained by adding halogen flame retardants to obtain excellent flame retardancy. Although halogen materials have good flame retardancy, when a fire occurs, a large amount of smoke and hydrogen halide gas will be released. These smoke and hydrogen halide gas can irritate the human eyes and respiratory system, causing symptoms such as dizziness, coma, dyspnea, suffocation and death. Moreover, there are often free halogens in halogen flame retardants, which will produce halogen acids in humid climates. Halogen acid will corrode electrical equipment and cause a short circuit in the circuit system

In addition, during use, traditional fireproof blockages are often solidified due to seasonal changes, ambient temperature and other reasons. After solidification, the volume shrinks to form gaps, resulting in poor sealing and potential safety hazards; After the blocking material is washed by rainwater, it is easy to be damp and deformed, the stability performance is poor, and the effectiveness of fire resistance is seriously affected
