Fireproof thermal-insulation functional material and structure for special carriages

Abstract

The invention discloses a fireproof thermal-insulation functional material and a structure for special carriages. The fireproof thermal-insulation functional material sequentially comprises a fireproof thermal insulation layer (1), a carriage or shelter body steel plate (2) and a thermal insulation layer (3) from the outside of a carriage or a shelter to the inside of the carriage or the shelter,wherein the fireproof thermal insulation layer (1) is composed of a protective finish paint layer (11), an anti-burning functional layer (12), a heat insulation functional layer (13) and a rust-proofbase body layer (14); the thermal insulation layer (3) is composed of a high-temperature-resistant thermal-insulation layer (31) composed of a high-thermal-resistance layer (312), and a high-reflection layer a (311), and a low-heat-conduction thermal-insulation layer (32) composed of a high-heat-resistance layer a (322) and a high-reflection layer b (321); and the periphery of a multi-layer structure composed of the high-temperature-resistant thermal-insulation layer (31) and the low-heat-conduction thermal-insulation layer (32) is wrapped with fiber cloth (33). The structure is good in fireproof performance, good in heat insulation effect, high in efficiency, small in thick bottom, low in weight, tight in connection of all layers and not prone to falling off.

Description

technical field [0001] The invention relates to the technical field of fire prevention and heat insulation, in particular to a fireproof heat preservation and heat insulation functional material and structure for a special carriage. 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 at such extremes, in order to ensure that the internal equipment is within the normal operating temperature range, thermal protection design for the vehicle or shelter is required. Today's conventional vehicle thermal protection design is mainly aimed at the engine heat and the impact of the sun on the driver's cabin or cabin, and usually uses a combination of externally sprayed heat-insulating coatings or laying heat-insulating materials on the inner walls to insulate the heat. [0003] Traditional thermal insulation coati...

AI Technical Summary

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

[0005] Due to the importance of the internal materials or equipment of special compartments or shelters, the external fireproof temperature of the compartments or shelters is usually above 1000°C, and the weight and thickness of traditional heat insulation coatings or insulation materials will be very large, which is obvious It does not meet the requirements of modern industry for the coating of carriages or shelters; and, for the extreme working conditions of special vehicles or shelters, such as when the carriages or shelters are covered by flames for a long time, the maximum temperature of the compartments or shelters has long been If the operating temperature range of the foam insulation material is exceeded, if the traditional foam insulation material is used for treatment, the foam insulation material will burn, melt or carbonize, which will affect its protective performance and even affect the internal safety performance
