Abstract
The utility model discloses a composite material capable of protecting high temperature instant flames and performing heat insulation, the composite material, from the outer to the inner, successively comprises: a fireproof external layer, a thermal insulation layer, an air layer, and a flame resistance internal layer. The fireproof external layer material is advantaged by flame resistance, high temperature resistance, no fusion and dripping phenomenon, large breaking strong force and tearing strong force, as well as good heat stability. The high temperature resistance thermal insulation layer is advantaged by high temperature resistance, light weight, low conductivity factor, and good heat stability. the air layer is provided with a lower conductivity factor. The flame resistance internal layer material can satisfy requirement for flame resistance. The composite material capable of protecting high temperature instant flames and performing heat insulation can be widely used for individual protection devices in different industries and fields such as fire fighting, national defense, etc.
Description
Technical field
The present invention relates to a kind of protection composite, be specially instantaneous flame of protection high temperature and heat insulation multilayer materials; Belong to the anti-tool material field of fire-fighting.
Background technology
Along with developing rapidly of Chinese national economy, catastrophic failures such as the blast in domestic industry production, the social life, fire take place frequently, and the complexity of fire, destructiveness be all towards compoundization, large scale development.Fireman's rescue mission is heavy day by day, and its difficulty and degree of danger are also increasing.From the case of fire fighter's injures and deaths fire fighting and rescue in recent years, self equipment of fireman is equipped with and can not satisfies the requirement of fighting in the modern scene of a fire far away, and fireman's operation protective gear is increasing to the dependence of new material and letter technology.Therefore the rescue protective gear of function admirable is provided for the fireman, guarantee the personal safety of fireman in the rescue process, the fireman of the development Nover practical protective materials of putting out a fire just more and more becomes the important topic that the scientific worker faced in weaving face fabric field.
Summary of the invention
The objective of the invention is to satisfy the defective that the emergency rescuing protection in TRANSIENT HIGH TEMPERATURE environment such as blast requires to solve traditional armored fabric of the prior art for a kind of instantaneous flame of high temperature and heat insulation composite of protecting is provided.
Purpose of the present invention can be achieved through the following technical solutions.
A kind of instantaneous flame of high temperature and heat insulation composite of protecting, be followed successively by from outside to inside: fire prevention is outer, thermal insulation layer, air layer and fire-retardant internal layer.
Described fire prevention skin is commercially available basalt fabric.
Described thermal insulation layer is the aerogel heat-proof panel (the IP650 aerogel heat-proof panel of being produced by Shaoxin City nano Gao Ke Co., Ltd) of high temperature resistant, light weight, low heat conduction.Described aerogel heat-proof plate thickness is 6mm.
Described air layer is formed by the shape memory alloy spring that operating temperature is about 45 ℃ pagoda shape.
Pagoda shape shape memory alloy spring in the described air layer and fire-retardant internal layer quilting are together.
Described fire-retardant internal layer is commercially available fire-retardant lining of fragrant sulfone synthetic fibre or retardant cotton.
Multilayer material of the present invention is in passing through 700 ℃ high-temperature region 30s, and material internal layer temperature can be above 45 ℃.But fire prevention cladding material flame-resistant high-temperature-resistant, no fusion, drip phenomenon, thermal stability is good.The high temperature resistant heat insulation layer can be high temperature resistant, light weight, thermal conductivity factor is low, thermal stability good.Air layer has lower thermal conductivity factor.Fire-retardant inner layer material satisfies the fire resistance requirement.Can protect in the individual protection equipment in the different industries such as be widely used in fire-fighting, national defence of instantaneous flame of high temperature and heat insulation composite and field.
In addition, the pagoda shape shape memory alloy spring is flat before startup, will return to pagoda shape in case reach its operating temperature.Its SME makes composite of the present invention only just provide necessary thermal insulation protection when being subjected to the threat of fire and heat, and under normal conditions, only provides lower thermal insulation, conforms with the comfortableness requirement.
Description of drawings
