Problems solved by technology

For the extreme working conditions of special vehicles or shelters, such as when the compartment or shelter is covered by flames for a long time, the maximum temperature of the compartment or shelter has already exceeded the operating temperature range of foam insulation materials. At this time, foam Insulation will burn, melt or carbonize, affecting its protective properties and even internal safety
At the same time, traditional thermal insulation materials are thick and heavy, which are not suitable for special carriages or shelters

Abstract

The invention discloses a heat-insulating material and structure for a special carriage or shelter, which is coated on the inner wall surface of the carriage or shelter steel plate (1); High-temperature insulation layer (2), low thermal conductivity insulation layer (3); the high-temperature-resistant insulation layer (2) is a multi-layer laminated structure, followed by high reflection layer a (21) and high thermal resistance layer a (22) alternately Lamination; the low thermal conductivity insulation layer (3) is a multi-layer laminated structure, in which the high reflection layer b (31) and the high thermal resistance layer b (32) are alternately laminated; the high temperature resistant heat insulation layer (2) and the low thermal conductivity The surroundings of the multilayer structure composed of the insulation layer (3) are evenly covered with fiber cloth (4). The invention has small thickness, low weight, good heat insulation effect, and high efficiency; at the same time, the invention has good fixing and positioning effects, and will not easily fall off, flang and the like.

Description

technical field [0001] The invention relates to the technical field of fire prevention and heat insulation, in particular to a heat insulation material and structure for special compartments or shelters. Background technique [0002] Special vehicles or shelters may face extreme flame environments during use, such as external gasoline, diesel and other combustible combustion environments. When special vehicles or shelters are in such extremes, in order to ensure that the interior equipment is within the normal operating temperature range, in addition to spraying fire-resistant and heat-insulating coatings on the outside of the compartment or shelter skin, insulation coatings will also be laid inside the compartment or shelter. The thermal insulation layer further reduces the heat transferred from the outside of the compartment or shelter, so as to ensure the normal operation of the equipment or devices inside the compartment under the condition of external high temperature. ...
