Abstract

The invention discloses a thermal-insulation and heat-preservation material for a special-type carriage or square cabin and a structure. The surface of the inner wall of a carriage or square bin steelplate (1) is coated with the material, and the material comprises a high-temperature-resistance thermal-insulation layer (2) and a low heat-conduction heat-preservation layer (3) from the inner surface of the carriage or square bin steel plate (1) to the inside in sequence. The high-temperature-resistance thermal-insulation layer (2) is of a multilayer stacked structure and is sequentially composed of high reflection layers a (21) and high heat resistance layers a (22) which are alternately stacked. The low heat-conduction heat-preservation layer (3) is of a multilayer stacked structure and is sequentially composed of high reflection layers b (31) and high heat resistance layers b (32) which are alternately stacked. The peripheries of the multilayer structure consisting of the high-temperature-resistance thermal-insulation layer (2) and the low heat-conduction heat-preservation layer (3) are uniformly covered with fiber cloth (4). The thermal-insulation and heat-preservation materialhas small thickness, low weight, a good thermal-insulation and heat-preservation effect and high efficiency. Meanwhile, the thermal-insulation and heat-preservation material has a good retaining and positioning effect, and is not liable to generate the phenomena such as shedding and up-turning.

Description

Technical field [0001] The invention relates to the technical field of fire protection and heat insulation, and in particular to a heat insulation material and structure for a special carriage or shelter. Background technique [0002] Special vehicles or shelters may face extreme flame environments during use, such as external gasoline, diesel and other combustibles. When special vehicles or shelters are at such extremes, in order to ensure that the interior equipment is within the normal operating temperature range, in addition to spraying fire and heat insulation coatings on the exterior of the cabin or shelter, partitions will also be laid inside the cabin or shelter. The thermal insulation layer further reduces the heat transferred from the outside of the cabin or shelter to ensure the normal operation of the equipment or devices inside the cabin under the external high temperature. [0003] When the conventional car or shelter is designed for thermal insulation, because the e...
