Technical field
The utility model relates to a kind of vacuum heat-insulating plate, relates to a kind of vacuum heat-insulating plate that adds infrared reflecting layer.
Background technique
In the development of energy technology, 20th century were full-blown centuries of Thermo Isolation Technique.Under the pattern that world economy advances fast, environmental protection and energy-conserving and environment-protective are the two principal themes that thereupon produce.Researching and developing out a kind of thermoinsulation material efficient, environmental protection is the urgent need that solve environmental pollution and lack of energy, and the vacuum insulation plate technique arises at the historic moment thus.Vacuum heat-insulating plate (VIP) is based on the vacuum insulation principle and a kind of novel, the effective insulating materials made, it is a kind of new and effective thermoinsulation material of in recent years R and D, realize isolated heat conduction by improving to greatest extent in the plate degree of vacuum and filling with the sandwich layer thermoinsulation material, thereby reach insulation, comparatively desirable insulation effect and the purpose such as energy-conservation.Than thermoinsulation materials such as traditional polyurethane foam or glass fibres, vacuum heat-insulating plate is in its production and application process, do not use the ODS material, and thermal conductivity can reach 0.003W/ (m.K)-0.004W/ (mK), be equivalent to 10 times of the conventional insulation material even higher, and its thickness only is 1/7 of conventional insulation material, thereby has environmental protection and energy-conservation two-fold advantage.
At present, known vacuum heat-insulating plate is comprised of high-resistant diaphragm, thermal insulating material and getter, be in thermal insulating material, add getter put into high-resistant diaphragm then vacuumize the sealing technique.This vacuum heat-insulating plate requires high to thermal insulating material, and if to reach certain thermal conductivity value, then must increase the thickness of thermal insulation layer, consume material increases cost of production.
The model utility content
The utility model purpose is intended to overcome the defective of prior art, and a kind of raising adiabatic efficiency is provided, and saves the method for core material.
For realizing that the technological scheme that the purpose of this utility model adopts is: a kind of vacuum heat-insulating plate that adds infrared reflecting layer is provided, its feature is owing to being comprised of high-resistant diaphragm, thermal insulating material, infrared reflection films and getter, multi-disc thermal insulating material lamination is placed, place one deck infrared reflection films between the lamination core, its area equates with the core area.Its infrared reflection films is thick to be 100 ~ 500 um.Infrared reflection films is the material that applies infrared external reflection at the PU film surface, is titanium oxide, or is silica, or be zine oxide.It is characterized in that having hole on the film, be shaped as circle, or oval.Or rectangle.Hole area is 20 ~ 80mm
2, the shared thin plate percentage of hole area is that 5% ~ 20%, two hole distance of center circle must not be less than 20mm.
The invention also discloses a kind of making method of adding the vacuum heat-insulating plate of infrared reflecting layer, it is characterized in that comprising the step of following order:
(1) pretreated core and infrared reflection films are stacked together successively;
The core that (2) will be placed with reflecting coating is packed in the bag-shaped high-isolation film, and adds getter;
(3) get rid of air in the bag-shaped high-isolation film with vacuum packaging machine, form high vacuum state;
(4) under high vacuum state, the moulding of encapsulated vacuum thermal shield.
Effect: the utility model compared with prior art has the following advantages:
(1) because interlayer is put into the adiabatic efficiency that infrared reflection films can significantly improve vacuum heat-insulating plate;
(2) can save thermal insulating material;
(3) can reduce the thickness of vacuum heat-insulating plate.
