Abstract

The invention provides a multifunctional fireproof air pipe which is prepared by the following raw materials in parts by weight, 65-75 parts of mullite, 30-50 parts of natural zircon sand, 4-8 parts of forsterite, 6-8 parts of phenolic resin, 0.69-1.275 parts of silencing agent and 0.15-0.2 part of antistatic agent. The antistatic agent is one or several of polyethylene oxide, polyether-ester-amide, and carboxyl betaine graft copolymers. The multifunctional fireproof air pipe is high in thermal shock stability, has stable antistatic property, the anti-blocking property and high safety performance. The multifunctional fireproof air pipe has high silencing performance, no silencer is required to be mounted independently, and thus the cost is saved.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a multifunctional fire-resistant air duct with antistatic and sound-absorbing properties. Background technique [0002] Fire-resistant air duct, also known as fire-resistant air duct, is a safety and life-saving system in a building. It refers to an air duct that can still maintain normal functions for a certain period of time after a local fire occurs in a building. They are mainly used in life-saving support systems for smoke exhaust and positive pressure air supply during fires, and can generally be divided into different requirements levels such as lh, 2h, and 4h. At present, the fire-resistant air ducts used in the market mainly include iron sheet air ducts, glass fiber composite air ducts, magnesium oxychloride cement air ducts, and hydraulic inorganic glass fiber reinforced plastic air ducts. , thermal insulation, and moisture-proof effects, but due to their ...
