Abstract
The invention discloses a kind of vacuum heat-insulating plates of novel low bridge long-life, including core material, first covering material and the second covering material, the top and bottom end of the core material are both provided with the first covering material, first covering material uses metal-base film, the both sides of core material are both provided with the second covering material, and second covering material using metallized film or without metal composite film, the present invention can substantially reduce the heat bridge effect of vacuum heat-insulating plate, heat bridge effect is substantially better than conventional metals basement membrane vacuum heat-insulating plate, meet the long life requirement that vacuum heat-insulating plate uses simultaneously, after vacuum heat-insulating plate is made using Novel back envelope formula structure, good stability of the dimension, product corner is concordant after flanging, especially in splicing, gap is small, improve heat insulation effect.
Description
Technical field
The present invention relates to heat preservation technology field more particularly to a kind of vacuum heat-insulating plates of novel low bridge long-life.
Background technology
Vacuum heat-insulating plate（VacuumInsulationPanel）It is a kind of Novel heat insulation material that fast development is got up in recent years
Material, compared to heat-insulating materials such as traditional polyurethane foams or glass fibre, VIP is not used in its production and application process
Ozone depleting substances（Ozone Depleting Substances）, and thermal coefficient can reach 3 ~ 4mW/m*K, heat
Resistance be equivalent to 10 times of conventional insulation material it is even higher, and its thickness is only the 1/7 of conventional insulation material, has environmental protection and section
The two-fold advantage of energy, thus be widely used in fields such as refrigerator, buildings, it is state-of-the-art high-efficiency insulated in the world at present
Material.
In VIP structures, core material is coated in barrier layer and carries out vacuumizing encapsulation.No matter core material or Obstruct membrane layer choosing are used
Which kind of material can generate heat bridge effect in its edge when barrier layer is for coating core material, form heat bridge.The production of heat bridge effect
Life is inevitable, and mainly since plank is formed by edge heat passage with ambient enviroment partial heat is lost in,
Plank overall thermal conductivity is caused to increase, to make plank entirety heat-insulating property decline.It is this for the composite membrane of metallization
It increases negligible；And for typical Metal Substrate VIP, this growth greatly affects VIP up to 60% or even 380%
The whole using effect of plank, and practical heat-insulating property.
Invention content
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of novel low bridge proposed is long-lived
The vacuum heat-insulating plate of life.
To achieve the goals above, present invention employs following technical solutions：
A kind of vacuum heat-insulating plate of novel low bridge long-life, including core material, the first covering material and the second covering material, institute
It states the top of core material and bottom end and is both provided with the first covering material, the first covering material uses metal-base film, the both sides of core material
It is both provided with the second covering material, and the second covering material is using metallized film or without metal composite film.
The beneficial effects of the invention are as follows：
It is long to devise a kind of novel low bridge for the drawback that traditional vacuum heat-insulating shield heat bridge effect is big, lifetime is short by the present invention
The vacuum heat-insulating plate in service life.The vacuum heat-insulating plate uses special four edge sealing types film bag, and metal is used respectively in film bag positive and negative
Group compound film ensures life of product；Meanwhile correspond to two sides of vacuum heat-insulating plate in film bag, using metallization composite membrane or
Without metal composite film, the influence of heat bridge effect is reduced.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the vacuum heat-insulating plate of novel low bridge long-life proposed by the present invention.
In figure：1 first covering material, 2 second covering materials, 3 core materials.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1, a kind of vacuum heat-insulating plate of novel low bridge long-life, including core material 4, the first covering material 1 and
Second covering material 2, the top and bottom end of core material 4 are both provided with the first covering material 1, and the first covering material 1 uses Metal Substrate
The both sides of film, core material 4 are both provided with the second covering material 2, and the second covering material 2 is multiple using metallized film or without metal
Close film.
In the present embodiment, using special four edge sealing types film bag, metal-based compound film is used respectively in film bag positive and negative, is protected
Demonstrate,prove life of product；Meanwhile two sides of vacuum heat-insulating plate are corresponded in film bag, using metallization composite membrane or without metal composite
Film reduces the influence of heat bridge effect.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
