Abstract
The invention discloses a laminated VIP (vacuum insulation panel) fiberglass core material. The laminated VIP fiberglass core material is characterized by being formed by laminating fiberglass core material pieces different in density and thickness. The density of the core material pieces ranges from 50 kg/m<3> to 300kg/m<3> and the thickness of the same ranges from 0.1mm to 1mm. The fiberglass core material pieces high in density and the fiberglass core material pieces low in density are laminated in a staggered manner, and/or the fiberglass core material pieces large in thickness and the fiberglass core material pieces small in thickness are laminated in a staggered manner. The laminated VIP fiberglass core material has the advantages that the resilience ratio of the laminated VIP fiberglass core material is lower than a fiberglass core material low in density and small in thickness, a VIP produced from the laminated VIP fiberglass core material is more excellent in thermal conductivity coefficient than a VIP produced from fiberglass pieces high in density and large in thickness by means of lamination; the laminated VIP fiberglass core material can be used as a thermal insulation component or thermal insulation filler in the fields of construction, machinery, thermal energy and the like, and can be also used as a core material of a vacuum insulation panel.
Description
Technical field
The present invention relates to a kind of inorganic composite material felt, particularly relate to a kind of VIP glass fibre core of lamination.
Background technique
Current, electricity price soars all the way, and the energy cost day by day risen brings resource pressure year after year to many families.Refrigerator is the necessity of the daily life of the common people, and needs the moment in the whole year ceaselessly to keep running.Thus, its power consumption is particularly huge.Modernization refrigerator not only needs to possess sufficient space to store all fresh foods, also must possess the high feature of energy saving.High performance vacuum heat-insulating plate (VIP) obtains ample scope for abilities in fields such as energy-saving refrigerator, refrigerator-freezer and refrigerator cars undoubtedly.
Fiberglass vacuum insulation panel (GF-VIP) is made up of the efficient obstructing film in surface, glass fibre core, getter or siccative, it is a kind of novel, energy-efficient heat-insulation material, thermal conductivity can be low to moderate 0.003mW/ (mK) below, becomes the material that thermal conductivity is minimum in the world at present.Glass fibre core is the support of VIP, is a kind of porous felt, has high porosity ratio, is the key determining VIP thermal conductivity.
The inspection method of the glass fiber laminate patent of invention that publication number is CN101147025B disclosing Vacuum thermal insulating material and use.This Vacuum thermal insulating material adopt low fragility and the glass fibre be reinforced by the duplexer of stacked formation, there is excellent heat-insulating property and the advantage of low cost.
Publication number be CN100473886C patent of invention on disclose a kind of glass fibre and phenolic composite core material vacuum heat insulation plate and preparation method thereof.Wherein, core adopts three-decker, and upper and lower layers is glass fibre, and mesosphere is foamable phenolic.The vacuum heat-insulating plate density that this method obtains is low, compressive strength is high, and reduces the pollution to vacuum system.
At present, VIP core adopts the glass fibre core sheet of same specification by being formed by stacking.After evacuation, thickness significantly reduces glass fibre core, has certain intensity, for the use of VIP provides guarantee.But along with the prolongation of VIP active time, air pressure inside raises gradually, the resilience of glass fibre core is obvious, reduces the Security of VIP.
Summary of the invention
Technical problem to be solved by this invention is the shortcoming overcoming existing VIP glass fibre core, a kind of VIP glass fibre core of lamination is provided, this core can be used as heat insulating element or the thermal insulating filling in the field such as building, machinery, heat energy, also can be used as the core of VIP.
The VIP glass fibre core of lamination of the present invention, is characterized in that by the glass fibre core sheet of different densities, different-thickness by being formed by stacking.The density of core sheet is 50 ~ 300kg/m
3, thickness is 0.1 ~ 1mm.
In general, the glass fibre core sheet of low density, low thickness has the high feature of rebound degree.By overlap-add procedure, VIP thermal conductivity prepared by the glass fibre core sheet of low density, low thickness is lower.Comparatively speaking, the glass fibre core sheet rebound degree of high density, high thickness is low, but the VIP thermal conductivity prepared after overlap-add procedure is higher.VIP prepared by these two kinds of core sheets all has self obvious weakness, can not provide service for the energy-saving field product of high-quality.The present invention by glass fibre core sheet large for density and the little glass fibre core sheet cross laminates of density, and/or by glass fibre core sheet large for thickness and the little glass fibre core sheet cross laminates of thickness, to reach the object reducing rebound degree and thermal conductivity.
Compared with existing VIP glass fibre core, the invention has the advantages that: the rebound degree of the VIP glass fibre core of the lamination described in (1) is lower than the glass fibre core of low density, low thickness, the VIP of preparation is more excellent by the VIP thermal conductivity prepared after overlap-add procedure than the glass fiber sheets of high density, high thickness again; (2) cost is low, waste material recoverable.
