Description

A kind of new insulation construction
Technical field
Patent of the present invention is related to heat preservation technology field, particularly a kind of new insulation construction.
Background technology
When observatory is built in some extreme environments, it is necessary to be kept the temperature to electronic equipment, such as build Being located at the observatory on polar region plateau just needs to keep the temperature the overall structure of telescope, it is ensured that telescope internal temperature More than -30 DEG C, ensure inside electronic component can normally work, due to telescope rack pointing accuracy requirement very Height, the lighting therefore it is required that rack-mounted material is tried one's best, so that the rotation precision of rack could not be influenced, but now such as Modern thermal insulation material does not often possess this characteristic, so a kind of lighter novel heat preservation structure of design just seems particularly heavy Will.
The content of the invention
The present invention improves the flatness of its outer surface by metallizing to glass fibre solid composite material layer, so as to drop The low radiance to the external world, plays more preferable heat insulation effect, and smooth outer surface also can be prevented effectively on extreme plateau The deposition of snowfall under environment, and invented a kind of new insulation construction.
To solve above-mentioned technical problem, the present invention provides a kind of new insulation construction, including cover body, the cover Body is by core and is wrapped in the sandwich that the covering of core outer surface formed, and the upper and lower surface of the core is respectively set There is one layer of covering, the core is aerogel layer, and the covering is glass fibre solid composite material layer, the glass Fiber solid composite material layer is connected on the outer surface of aerogel layer by plastic bonding,
The glass fibre solid composite material layer is polymer matrix composites, the glass fibre solid composite material The bed of material is by curing a kind of composite material formed by glass fabric and resin.
Further：The glass fabric and the mixed proportion of resin are 65:35, solidification temperature is 45 DEG C, and the time is 2h。
Further：The thickness of the aerogel layer is 6mm, the interlayer composite material layer, skin thickness 1- 3mm。
Further：The heat transfer system that the glass fibre solid composite material layer is formed with aerogel layer thickness ratio Counting formula is：
D1、K1、D2、K2The thickness and thermal conductivity factor of glass fibre solid composite material layer and aerogel layer are represented respectively.
Further：Realized and metallized by mould above in the outer surface of the glass fibre solid composite material layer.
Further：Flatness ± the 1mm of the glass fibre solid composite material layer outer surface.
With the above structure the device have the advantages that being：
1st, lightweight：The pointing accuracy requirement of telescope rack is very high, therefore it is required that rack-mounted material is as far as possible light Matter, does not influence the rotation precision of rack.The covering of this structure is glass fabric solid construction, which is not losing Weight is further mitigated on the premise of heat-insulating property, and the aerogel material as core is also typical light material.
2nd, designability is good：The structure is made of two kinds of main materials：Glass fibre solid composite material layer and aeroge, The coefficient of heat conduction of composite material can be adjusted by controlling the thickness ratio of two kinds of materials.
3rd, outer surface design is strong：Insulation construction outer surface metallizes and has the requirement of flatness, on the one hand reduces to the external world Radiance, play more preferable heat insulation effect；On the other hand, smooth outer surface also can be prevented effectively in extreme altitude environment The deposition of lower snowfall.
Brief description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the structure diagram of the present invention.
Embodiment
A kind of new insulation construction as shown in Figure 1, including cover body, the cover body are by core and are wrapped in core The sandwich that the covering of outer surface is formed, the core are aerogel layer 1, and the covering is solid multiple for glass fibre Condensation material layer 2, the glass fibre solid composite material layer 2 are connected on the outer surface of aerogel layer by plastic bonding, The glass fibre solid composite material layer 2 is polymer matrix composites.The covering of this structure is glass fibre entity, the illiteracy Skin structure further mitigates weight on the premise of heat-insulating property is not lost, and the aerogel material as core is also typical case Light material, the present invention passes through the shadow that reduces the weight of rack-mounted thermal insulation material to reduce to gantry rotation precision Ring；Aeroge and glass fiber compound material is respectively adopted in core and the covering in the design, both materials are independent The coefficient of heat conduction be respectively 0.01-0.02W/ (K × m) and 0.06-0.08W/ (K × m), therefore the coefficient of heat conduction of insulation cover It is the combination of both parameter, can be adjusted according to the portfolio ratio difference of two kinds of materials；It is and compound using glass fibre Material is because he possesses certain rigidity as covering, thus can be very easily installed on telescope, and is played The effect of protective cover.Its coefficient of heat conduction will not drag down the heat insulation effect of aeroge also than relatively low at the same time, also be exactly a bit Both materials can be cemented together together when glass fibre is molded, in technique easily；And use glass fibers Dimension is very smooth as the insulation cover surface of covering, can prevent the deposition of snowfall, this is the special demands in the environment of polar region.
Above-mentioned glass fabric and the mixed proportion of resin are 65：35, solidification temperature is 45 DEG C, time 2h, institute The thickness for the aerogel layer stated is 6mm, and the thickness of the glass fibre solid composite material layer is 1-3mm；The basis The coefficient of heat conduction formula that glass fabric composite layer is formed with aerogel layer thickness ratio is.
D1、K1、D2、K2The thickness and thermal conductivity factor of glass fibre solid composite material layer and aerogel layer are represented respectively.
The present invention can adjust the mixing ratio of glass fabric and resin according to actual conditions, so as to complete to thermal insulation material The adjustment of the coefficient of heat conduction, plays the role of increasing practical performance.
The outer surface of above-mentioned glass fibre solid composite material layer metallization, the glass are realized by mould above The flatness requirement of fiber solid composite material layer outer surface is ± 1mm.The present invention is by glass fibre solid composite material Layer metallizes to improve the flatness of its outer surface, so as to reduce to extraneous radiance, plays more preferable heat insulation effect, and Smooth outer surface also can effectively prevent the deposition of the snowfall under extreme altitude environment.
In summary the device have the advantages that being：1st, lightweight：The pointing accuracy requirement of telescope rack is very high, because This requires rack-mounted material to try one's best lighting, does not influence the rotation precision of rack.The covering of this structure is glass fibers Entity is tieed up, which further mitigates weight on the premise of heat-insulating property is not lost, and as the aeroge of core Material is also typical light material.2nd, designability is good：The structure is made of two kinds of main materials：Glass fibre solid composite Material layer and aeroge, can adjust the coefficient of heat conduction of composite material by controlling the thickness ratio of two kinds of materials.3rd, appearance Face design is strong：Insulation construction outer surface metallizes and has the requirement of flatness, on the one hand reduces to extraneous radiance, plays more Good heat insulation effect；On the other hand, smooth outer surface also can effectively prevent the deposition of the snowfall under extreme altitude environment.
