Description
Technical field
The present invention relates to field of heat insulating materials, more particularly to a kind of aviation heat-insulation and heat-preservation module.
Background technology
The classification that glass fibre cotton belongs in glass fibre, is a kind of manmade inorganic fibre.Using quartz sand, lime
The natural crystals such as stone, dolomite are primary raw material, coordinate the industrial chemicals such as some soda ash, borax to be melt into glass.In melting state
Under, cotton-shaped fine fibre is blow molded into by external force, is crossings on different level between fiber and fiber, is intertwined mutually, shows perhaps
More tiny gap, this gap can regard hole as.Therefore, mineral wool can be considered porous material, have good thermal insulation, sound absorption
Performance.The reason for mineral wool can absorb sound is not due to rough surface, but because with the substantial amounts of inside and outside micro hole connected
Gap and hole, when on sound wave incident to mineral wool, sound wave can enter material internal along hole, cause air molecule in space
Vibration.Due to the viscosity resistance and air molecule of air and the friction of pore wall, acoustic energy is converted into heat energy and is lost.
Glass fibre cotton is widely used in aerospace field frequently as insulation material.Aerospace field is to thermal insulating material
The requirement of material is higher, it is conventional bonded with sizing material after overmolded glass fibre cotton insulation material low intensity, processability is installed
Can be poor, heat insulation effect is poor, quality weight, it is impossible to meets requirement, the glass fibre guard glass fibre cotton of exclusive use problem of making moist is serious, ties up
Protect it is costly, be unsuitable for for a long time be on active service.
Application publication number is that CN201310669184.6A Chinese invention patents are related to a kind of aviation special-purpose thermal insulation heat-intercepting glass
Fibrous composite, including terylene non-woven fabric, glass fibre cotton and bonding sizing material, the nonwoven thickness is 0.05-0.1mm,
A diameter of 0.75-1.25 μm of the glass fibre cotton, the cohesive sizing material are phenolic resin, and its weight is composite gross weight
0.8-1.2%, the glass fibre cotton are compounded in nonwoven surface by bonding sizing material.The invention prepares the side of the composite
Method, appropriate zinc oxide, borax, white sand, feldspar in powder, soda ash, calcite, potassium carbonate, barium carbonate and mixed melting are taken first；So
By for the first time into drawing to obtain glass fibre cotton with high temperature, high velocity air after fibre；Then glass fibre cotton is dispersed in non-woven fabrics
Surface simultaneously sprays applying glue, finally dry product.The thermal conductivity factor of the insulation insulated fibre glass composite of the invention is low, resistance to
High-temperature behavior is excellent, and density is low, and intensity is high, but the problem of making moist that glass fibre is exposed in air does not solve.
Application publication number is that CN201310630801.1A Chinese invention patents are related to a kind of aviation ship insulation material,
It includes the first tin layers of compound setting successively, fiber composite, the second tin layers, glue-line and protection film layer, the fiber composite
Layer is counted in parts by weight to be made by following each component：Carbon fiber 3-7 parts, polystyrene resin 11-15 parts, foaming agent 1-2
Part, aluminium hydroxide 5-7 parts, toluene di-isocyanate(TDI) 20-30 parts, polyethers 6-8 parts, stannous octoate 0.05-0.08 parts, triethyl group two
Amine 0.05-0.08 parts and phosphorus trichloride 1-3 parts, protection film layer use brown paper, above-mentioned aviation ship insulation material, structure
Simply, the first tin layers, fiber, the second tin layers, glue-line and protection film layer are combined, production cost is low, high insulating effect, anti-
Tensile strength is high, but weight can not be controlled effectively when being used for aviation field.
The insulation material requirement that aviation field uses is high, it is necessary to possess lightweight, fire-retardant, anti-soil is corrosion-resistant, wear-resistant etc.
Etc. performance, multi-purpose glass fibre guard glass fibre cotton is as primary means air insulation material at present, for what is easily occurred in glass fibre use
Make moist, quality control the problems such as carry out technological improvement be extremely necessary.
