Description

A kind of core material of vacuum heat insulation plate and vacuum heat-insulating plate
Technical field
The utility model relates to a kind of core material of vacuum heat insulation plate and applies the vacuum heat-insulating plate of this core, be specifically related to a kind ofly at chopped silk core (adopting the lamination of the chopped thread sheet material of wet moulding) or the core material of vacuum heat insulation plate of superfine glass fiber cotton sheet material is set in dry method Chopped Strand Mat core or the chopped thread sheet material that contains at the same time wet moulding and the both sides up and down of the core of dry method Chopped Strand Mat, it is applicable to the fields such as household electrical appliances insulation, Cold Chain Logistics, building heat preservation.
Background technique
Current core material of vacuum heat insulation plate is generally selected porous media material, and as materials such as powdered silica, aerogel, glass fibre or microvoid polyurethanes, each material has its pluses and minuses.Secondly, every kind of central layer in use, must add siccative or getter, removes the gas and the moisture that do not eliminate in obstructing film and core, guarantees degree of vacuum, thereby improves the working life of vacuum heat-insulating plate.Vacuum heat-insulating plate has applied in every field, and it has met customer requirement with the characteristic of energy-conservation, low-carbon (LC), environmental protection, safety.Known by investigation and practical operation, selecting with making method of the inner core of vacuum heat-insulating plate is very large on its properties impact, core is generally selected porous media material, as aerogel, polyurethane foam, SiO 2 powder, asbestos fiber, glass fibre etc.For core material of vacuum heat insulation plate, must possess following four specific characters: 1, under the high vacuum negative pressure state, the vacuum insulation intralamellar part is had to supporting effect, prevent that vacuum heat-insulating plate from shrinking, caving in; 2, to reduce as much as possible heat conducting generation.3, must possess open-celled structure, gas can be discharged from prestissimo under negative pressure state; 4, material need possess under vacuum or ultralow degree of vacuum state, does not discharge gas or the least possible release gas.
At present because of vacuum heat-insulating plate application difference, the selection of its core is difference to some extent also.Require the resistance good in thermal property for household electrical appliances insulation, building heat preservation etc., thermal conductivity is low.Most thermal insulating material thermal conductivity is high, bulky, and thickness is generally between 1cm-5cm, and after household electrical appliances insulation, Cold Chain Logistics, building heat preservation, utilized space and the insulation life-span of having reduced household electrical appliances, building are short.Vacuum heat-insulating plate has been complied with each field insulation demand just, wishes the requirement that the attenuation of warming plate thickness, thermal conductivity reduce.
China Patent No.: ZL200880122390.2 discloses a kind of vacuum heat insulation material core material, i.e. chopped silk core, and the diameter of the glass fibre of employing is that 6-13um, length are 4-20mm; It forms by stacked multiple nonwovens; This nonwovens at least comprises many glass fibres that utilize continuous filament method to manufacture.In nonwovens, on the direction substantially parallel on the surface with nonwovens of the most of glass fibre in many glass fibres, extend.
Above-mentioned the deficiencies in the prior art part is: its fiber is directly thicker, and length is grown (diameter is that 6-13um, length are 4-20mm), and fiber is harder; For the vacuum heat-insulating plate (VIP) that adopts aluminizer to carry out outsourcing, vacuumize, in actual production or using process, described fiber is easy to pierce through aluminizer; So, when producing VIP, the sealing film material of outsourcing is not generally used aluminizer; Adopt at present foil laminated film to produce VIP, overcome the problems referred to above; And this has brought new problem, owing to containing aluminum layer (AL) and aluminium coated (VMPET) in foil laminated film, and this aluminium lamination thicker (being generally the 7um left and right), cause VIP can produce more serious heat bridge effect in actual application, this will inevitably cause the VIP overall thermal conductivity to increase, thereby affects energy-saving effect and product quality.
Aluminum layer in foil laminated film is the thin slice by highly purified aluminium form as thin as a wafer of formation after repeatedly rolling, and is good thermal conductor, and the purity of Packaging Aluminum Foil is more than 99.5%.
Contain aluminium coated (VMPET) in aluminizer, and do not contain aluminum layer (AL), therefore, the heat-conducting effect of aluminizer is far below foil laminated film.
Therefore, how, when adopting aluminizer to carry out the VIP encapsulation, avoiding fiber to pierce through aluminizer, is the technical problem that related domain will solve.
The model utility content
Technical problem to be solved in the utility model is to provide and a kind ofly adopts aluminizer to be encapsulated and can avoid fiber to pierce through the core material of vacuum heat insulation plate of aluminizer.
For solving the problems of the technologies described above, the utility model provides a kind of core material of vacuum heat insulation plate, it comprises: by the glass fibre sheet (being chopped silk core) of multilayer laminated employing wet type paper process moulding, or adopt the glass fiber mat (being dry method glass cotton core material) of dry method non-woven fabrics craft moulding, or the middle core of glass fibre sheet and lamination (the mixing core) formation of glass fiber mat; Be coated with the cotton sheet material of superfine glass fiber in the both sides up and down of this centre core; Fiber diameter in the cotton sheet material of described superfine glass fiber is that 1-4um, length are 1-5mm.
The cotton sheet material of described superfine glass fiber adopts wet type paper process moulding or the moulding of dry method non-woven fabrics craft.
The diameter that forms the glass fibre of described glass fiber mat is that 4-20um, length are 4-15mm.
