Flame-retardant antistatic water-resistant flexible heat preservation air duct

Abstract

The invention discloses a flame-retardant antistatic water-resistant flexible heat preservation air duct. The flame-retardant antistatic water-resistant flexible heat preservation air duct is characterized in that an air duct body is provided with an inner layer, a middle layer and an outer layer, flame-retardant antistatic flexible coating cloth is adopted for the inner layer and the outer layer, flexible flame-retardant heat preservation materials are adopted for the middle layer and bonded to the flame-retardant antistatic flexible coating cloth of the inner layer and the outer layer through flexible flame-retardant glue, the two ends of the air duct body are connected with a connection ring in a sealed mode, and both the front face and the back face of the flame-retardant heat preservation materials are provided with crusts. The air duct has the excellent flame resistance, antistatic performance, flexible performance and heat preservation performance, the two faces of the flexible flame-retardant heat preservation materials adopted for the middle layer of the air duct are provided with dense outer skin, the excellent heat isolation performance and excellent waterproof performance are achieved, and water vapor is prevented from penetrating into a heat preservation layer through the plastic coating cloth. The heat preservation air duct is very convenient to machine, transport and use.

Description

technical field [0001] The invention belongs to the technical field of channel ventilation, and in particular relates to a flame-retardant, anti-static, water-resistant and flexible thermal insulation air duct. Background technique [0002] During the construction of passageways such as mines, tunnels, subways, and air-raid shelters, as the construction develops deeper, the geothermal heat rises, coupled with the heat dissipation of a large number of electrical equipment, etc., resulting in high temperatures in many places on the working face, resulting in extremely harsh operating environments. In order to improve the environment of the working face, a refrigeration system is generally used to cool down the cold air supplied to the working face. Due to the limitation of the volume, weight and installation conditions of the refrigeration equipment, it is necessary to use the air duct to transport the cold air produced by the refrigeration machine to the working surface. Due...

Problems solved by technology

However, the cold air output from the refrigerator and the air humidity in channels such as mines, tunnels, subways, and air-raid shelters are high, and water vapor easily flows or infiltrates into the insulation layer through the cloth tube or the outer protective layer. Seriously affect the thermal insulation effect of the thermal insulation duct. At present, in the development process of the thermal insulation duct, few studies have paid attention to the above problems

[0003] At the same time, because mines, tunnels, subways, and air-raid shelters are all confined spaces, there are many restrictions on cargo transportation, and once a fire breaks out, it will be difficult for people to escape, which will bring huge safety hazards to construction and post-workers. At present, Insulation ducts that meet the requirements of flame retardancy, antistatic, water resistance, heat preservation, and ease of transportation are rarely reported, so the high temperature of working faces in mines, tunnels, subways, and air-raid shelters has always been a problem that plagues production companies and is difficult to solve
