Description
Technical field
The invention belongs to the thermoinsulation material field of engineering technology, specifically relate to a kind of inverse gas infiltration vacuum heat-insulating plate and packaging method thereof take glass fibre as core.
Background technique
Low-carbon (LC) and energy-saving and emission-reduction have become the elementary tactics of national energy strategy and economic life, research institution of country is is actively researching and developing the low energy consumption product or is improving existing equipment with when reducing its energy consumption, and also pay attention to day by day improves the heat-insulating capability of enclosed structure to prevent excessively scattering and disappearing of energy.Vaccum thermal insulation technique just arises at the historic moment under this background.The low 5mW/(m ﹒ k that reaches of glass fibre core heat conductivity of vacuum insulation panel) below, be the best thermal insulating material of present heat-insulating property.China starts late to the development of vacuum heat-insulating plate, but its technology is day by day perfect in China, and a lot of enterprises in the whole nation are are all actively researching and developing vacuum heat-insulating plate.
Vacuum heat-insulating plate relies on and significantly improves internal vacuum and realize adiabaticly, and the key of its making is except will being pumped in the vacuum heat-insulating plate the extremely low atmospheric pressure, and vacuum is an important technology in the retaining plate within the whole vacuum heat-insulating plate cycle in working life.And this task mainly relies on barrier to finish.
At present, the barrier of vacuum heat-insulating plate all adopts composite material both at home and abroad, generally all adopt aluminium foil and polyester-based to be composited, conventional vacuum heat-insulating plate barrier package bag as shown in Figure 1, formed by two barrier heat-sealings, generally first with the heat-sealing of three limits, then the glass fibre core that pretreatment is good is filled in the bag-shaped barrier, through vacuum chamber with core in gas extract out, and the heat-sealing four edges gets final product in vacuum chamber; The product profile that consists of as shown in Figure 2.Conventional vacuum heat-insulating plate is larger because of differential pressure inside and outside the plate, inevitably having a small amount of gas is penetrated in the plate by barrier and sealing, thereby the riser internal pressure causes the increase of heat conductivity of vacuum insulation panel, affect its thermal property, thereby reduced its working life, even if the existence of gas adsorption material is arranged, thus can not be for a long time and effectively absorb the gas that penetrates in the plate and guarantee not rise in whole life cycle internal pressure.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome the deficiencies in the prior art, a kind of vacuum heat-insulating plate of making a price reduction the inverse gas infiltration is provided, this packaging method of making a price reduction the vacuum heat-insulating plate of inverse gas infiltration also is provided simultaneously.
Technological scheme: in order to solve the problems of the technologies described above, the invention provides a kind of vacuum heat-insulating plate of making a price reduction the inverse gas infiltration, it comprises top layer gas barrier, glass fibre core and sealing; Glass fibre core outer surface parcel top layer gas barrier, two ends are provided with sealing; Described top layer gas barrier comprises: top layer hot sealing layer, top layer gas barrier layer, top layer heat resistant layer, top layer radiation protective layer; The top layer gas barrier sequentially is from inside to outside successively: top layer hot sealing layer, top layer heat resistant layer, top layer gas barrier layer, top layer radiation protective layer.Described top layer hot sealing layer adopts high density polyethylene (HDPE) or vinyl-acetic ester; The top layer gas barrier layer adopts polyvinyl alcohol or/and choke coats with lacquer, the general acrylic lacquer that adopts of choke lacquer; The top layer heat resistant layer adopts polyolefin, such as polyethylene or polypropylene or polyethylene and ethylene copolymers; The top layer radiation protective layer adopts metallic thin film, and metallic thin film generally adopts aluminium foil or stainless steel film.The thickness of top layer gas barrier is the 200-500 micron, and preferred 500 microns, the top layer gas barrier has lower gas permeability.
The core of glass fibre described in the present invention inside is provided with inner price reduction gas-barrier separated gas-bearing formation.Described inner price reduction gas-barrier separated gas-bearing formation is sandwich structure, and two-layer up and down is the internal heat seal, and middle one deck is inner gas barrier layer.The internal heat seal adopts high density polyethylene (HDPE) or vinyl-acetic ester; Inner gas barrier layer adopts polyvinyl alcohol or/and the choke lacquer.
The top layer gas barrier adopts tackiness agent with top layer hot sealing layer, top layer heat resistant layer, top layer gas barrier layer, top layer radiation protective layer bonding and presses together.
Inner price reduction gas-barrier separated gas-bearing formation adopts tackiness agent with internal heat seal and inner gas barrier layer bonding and presses together.
Described glass fibre core inside is provided with getter.Described Bond is: polyurethane adhesive.
A kind of packaging method of making a price reduction the vacuum heat-insulating plate of inverse gas infiltration, its step is as follows:
(1) with top layer gas barrier and inner price reduction gas-barrier separated gas-bearing formation, perhaps the top layer gas barrier adopts the mode elder generation inside back cover limit of heat-sealing to make bag, and an end is reserved vacuum orifice;
(2) the glass fibre core is placed in the interior chamber of bag afterwards to vacuumizing at interior glass fibre core;
(3) vacuumize and keep 1-3 minute post heat-seal.
The glass fibre core is separated by bag-shaped chamber independently among the present invention, and can prevent getter in the inside of glass fibre core, gas because inside and outside larger pressure reduction can trace be penetrated into outermost one deck vacuum heat-insulating plate, less because of pressure reduction between outermost one deck and internal layer, gas infiltration capacity is very little, thereby makes whole glass fibre core maintain good heat-insulating property under lower vacuum state.
Beneficial effect: the present invention compared with prior art has the following advantages:
1, vacuum heat-insulating plate of the present invention adopts the sublevel step-down, and gas permeates step by step, can effectively keep the heat-insulating property of vacuum heat-insulating plate, increases the service life.
2, sublevel step-down can effectively reduce gas to glass fibre core infiltration, in the situation of inapplicable getter, also can be for a long time in maintenance internal layer degree of vacuum, keep higher thermal resistance and heat-insulating property preferably.
3, outer field top layer gas barrier has also played protective action to internal layer, even in the situation that the top layer gas barrier is punctured, still can keep the whole heat-insulating property of vacuum heat-insulating plate.
4, vacuum heat-insulating plate of the present invention, effectively reduce gas permeation, prolonged the whole service life of whole vacuum heat-insulating plate, if the number of plies of the price reduction of the inside in vacuum heat-insulating plate gas-barrier separated gas-bearing formation is many, can save adsorbent, reduced cost of production, Security is good, stable high when using simultaneously.
