Description
Technical field
The utility model is related to a kind of heat-insulated blanket more particularly to a kind of compound blankets of novel heat-insulation.
Background technology
Glass fibre guard glass fibre cotton has excellent heat preservation and insulation because of its thermal conductivity factor very little, can be with as thermal insulation material
It is widely used in building heat preservation, pipe insulation, compartment heat preservation etc..Compared with traditional organic insulation material, glass fibre guard glass fibre cotton
Have many advantages, such as that low unit weight, soft texture, resilience are good, fire retardant performance is good.
Chinese invention patent application No. is 201310309202.X discloses a kind of effectively insulating blanket of glass wool structure,
It is characterized in that the structure is composed of Multilayer ultrathin blanket of glass wool with aerosil, the number of plies of aerosil
The number of plies for blanket of glass wool subtracts one.The propagation of hot-fluid is played the role of to obstruction, while airsetting in the presence of blanket layer structure
The nanometer level microporous of glue reduces thermal conductivity factor to a certain extent, improves the heat-proof quality of blanket.
Chinese invention patent application No. is 201310571797.6 discloses a kind of super layer structure extra-fine glass-wool felt, should
Blanket is the ultra-fine centrifugal glass fibre interlayer heap poststack by surface coated with resins binding agent, is formed through hot setting.The super layer
Structure extra-fine glass-wool felt fibre diameter is thin, and fibre diameter, in normal distribution, distance is 10 μm~100 μm between layers
Super layer structure, there is very high intensity close to parallel arrangement, blanket between each layer, thermal conductivity factor can reach 0.02W/ (m
K) (20 DEG C)~0.035W/ (mK) (20 DEG C) has excellent heat preservation thermal insulation, sound insulation and noise reduction performance.
Although foregoing invention patent all improves the heat-proof quality of blanket of glass wool to a certain extent, effect relatively has
Limit can not fundamentally increase substantially the heat-proof quality of blanket of glass wool.
Utility model content
The utility model overcomes the shortcomings of the prior art, and provides a kind of composite glass wool with effectively insulating performance
Felt.
It is for the technical scheme adopted for realizing the purpose of the utility model：A kind of compound blanket of novel heat-insulation is provided, it is special
Sign is to be combined by glass fibre guard glass fibre cotton and graphene layer are spaced.
Further, the number of plies of the glass fibre guard glass fibre cotton is 2~10 layers, and thickness in monolayer is 2~10mm.
Further, one layer fewer than the number of plies of glass fibre guard glass fibre cotton of the number of plies of the graphene layer, thickness in monolayer for 5~
100μm。
Further, the avarage fiber diameter of the glass fibre guard glass fibre cotton is gradually incremented by from top to bottom, wherein first layer glass
The avarage fiber diameter of glass fiber blanket is≤2 μm, and the avarage fiber diameter of second layer glass fibre guard glass fibre cotton is 2~4 μm, after
The avarage fiber diameter of each layer of glass fibre guard glass fibre cotton is 2 μm all more than last layer.
Application effect：The utility model compared with prior art, has the following advantages：(1) glass fibre guard glass fibre cotton is averaged
Fibre diameter increases step by step, forms multi-layer compound structure, the interface of heat between the layers is largely lost, due to every layer of glass
The avarage fiber diameter of glass fiber blanket is different, leads to the heat transfer modes of every layer of blanket and efficiency difference, the propagation of hot-fluid is risen
Certain inhibition is arrived.(2) per layer glass fiber blanket between have a layer graphene, since graphene is along in-plane
On thermal conductivity factor much larger than thermal conductivity factor on in-plane, can be rapid when heat transfer is to graphene layer
Entire plane is diffused into, it is possible to prevente effectively from the phenomenon that hot-spot, leads to everywhere temperature point of the compound blanket along in-plane
Cloth reduces heat along the transmission perpendicular to in-plane, improves the heat-insulating property of blanket than more uniform.
