First embodiment
The Vacuum thermal insulating material and the manufacture method thereof of the first embodiment of the present invention are described in conjunction with Fig. 1 to Fig. 5.
At first, with reference to Fig. 1 the structure of the Vacuum thermal insulating material 20 of present embodiment is described.Fig. 1 is the sectional view of the Vacuum thermal insulating material 20 of the first embodiment of the present invention.
The structure of this Vacuum thermal insulating material 20 possesses core 10 and has the external cladding material 1 of gas barrier property.The inside folding and unfolding of this external cladding material 1 has this core 10 and reduces pressure, and its periphery seals by the fusing gummed.This Vacuum thermal insulating material 20 is made of flat rectangular plate.
The structure of this core 10 possesses: the green wood 3 that constitutes by the inorfil congeries that does not comprise tackiness agent, waste wood 4 that constitutes by the inorfil congeries that does not comprise tackiness agent and folding and unfolding the interior clad material 2 of green wood 3, waste wood 4 and sorbent 5.Because the inorfil congeries folding and unfolding that will constitute green wood 3 and waste wood 4 in interior clad material 2, therefore, need not to reinforce green wood 3 and waste wood 4 with tackiness agent.Thereby, compare with the existing Vacuum thermal insulating material that uses tackiness agent, when can reducing electricity when making, consumption of heat energy, the utilization again of the waste wood by not comprising tackiness agent can realize reducing cost.Also have,, can make the handling property of core 10 better owing to make with the core 10 of waste wood 4 folding and unfoldings in the interior clad material 2.And, owing to do not use the inorganic bond of characteristic with easy moisture absorption, the moisture that makes green wood 3 and waste wood 4 be brought into is considerably less, when the stable Vacuum thermal insulating material of heat-insulating property can be provided, owing to do not use organic bond, can also prevent the deterioration of passing in time because of the heat-insulating property that organic bond generation gas causes.
But interior clad material 2 is made by the synthetic resin films such as polyethylene film that the thickness of hot-melt binding is approximately 20 μ m.Interior clad material 2 melts gummed shape pouch by the periphery with two films of rectangle.Also have, if when the thickness of interior clad material 2 made the 20 μ m left and right sides, then in guaranteeing in the ductility of clad material 2, after core being put into clad material 2 and being compressed decompression, the core of being convenient to clad material in the hot-melt binding inserts opening portion, and is easy to make the hot-melt binding anchor clamps.In addition, interior clad material 2, but be that density is 0.910g/cm by the organic film that makes hot-melt binding
3Or its above polyethylene film, and to make its thickness be 5～50 μ m, the bad phenomenon such as unrestrained that causes because of breakage in the time of then reducing compression seal core blank 10A, also have, owing to can keep the negative pressure state behind the compression seal for a long time, thereby the Vacuum thermal insulating material that has used the good core of handling property 10 can be provided.
External cladding material 1 constitutes with the stack membrane of plastic layer by having the gas barrier layer that stops gas permeation and being arranged at its inboard hot-melt binding.Specifically, external cladding material 1 has used the polyamide-based synthetic fiber resin film of 15 μ m, used the aluminum metal vapor-deposited film be 400～
The supporting layer of this vapor-deposited film is the polyethylene terephthalate film of 12 μ m, and to have used aluminum foil thickness be 6 μ m, and fusing gummed thin layer is that the aluminium film of the high-density polyethylene resin film of 50 μ m constitutes.
In external cladding material 1, itself and external cladding material 1 are seamlessly prepared core 10 folding and unfoldings, and had and the consistent in fact outer perimeter of the interior girth of external cladding material 1.In other words, be formed at the 1a of ear on three limits of external cladding material 1 and become position near the weak point of the side of core 10.Therefore, become the flanging that can not carry out the 1a of ear on three limits, just can solve the Vacuum thermal insulating material 20 of the variety of issue when the assembling refrigerator of bigger ear's initiation is arranged.
Secondly, Fig. 2 to Fig. 5 of each manufacturing process of reference expression first embodiment describes the manufacture method of first embodiment's Vacuum thermal insulating material 20.Fig. 2 has cut off the stereogram of the state of green wood 3 for expression, the stereogram of the state that Fig. 3 makes up green wood 3, waste wood 4 and sorbent 5 for expression, Fig. 4 for expression with core blank 10A folding and unfolding interior clad material 2 in and reduce pressure and the sectional view of the state that seals, Fig. 5 is the stereogram of the state representing core blank 10A is encased with interior clad material 2.
At first, as shown in Figure 2, cut off not the raw-material end of lamination of the rubber-like inorfil that solidifies with tackiness agent and make green wood 3.Thereby, when this green wood 3 is made of the lamination of the rubber-like inorfil that does not solidify with tackiness agent, also constitute by the lamination of the rubber-like organic fiber that does not solidify with tackiness agent from green wood 3 cut waste wood 4.In addition, in example shown in Figure 2, make green wood 3 owing to cut off the raw-material end of polylith simultaneously, therefore, producibility is good, but as required, also can cut off a raw-material end and make green wood 3.The green wood of producing 3 is the plate of rectangle, and cut waste wood 4 is thin rectangular residual limit.
Secondly, as shown in Figure 3, be paved with waste wood 4, make waste wood layer 6 at the upper surface of the green wood of producing 3.In other words, the thin rectangular waste wood 4 in residual limit that is produced during with making green wood 3 is arranged side by side in the upper surface of green wood 3, and it is plane that it is seamlessly become, to make waste wood layer 6.And then, make sorbent 5 be dispersed in the upper surface of this waste wood layer 6, again by green wood 3 is set in the above, thereby make core blank 10A.In other words, between green wood 3 up and down, clip when waste wood layer 6 kept, by in the gap between the green wood 3 of waste wood layer 6 and upside widely the granular sorbent 5 of dispenser kept, thereby make core blank 10A.So, even though the waste wood 4 that constitutes by the inorfil congeries that does not comprise tackiness agent with the less character of the big quality of outward appearance volume also can easily utilize again, and can realize reducing cost.
The weight of waste wood 4 and the ratio of the gross weight of core 10 are preferably in the scope of 10～80 weight %.The ratio of the waste wood 4 that produces during from making green wood 3 is considered, preferred 20～50 weight % of this ratio, and be 25 weight % in this first embodiment.
As mentioned above, kept, can be made having an even surface of core 10, be suitable for being arranged on the occasion in the refrigerator etc. by waste wood layer 6 being clipped between the green wood 3 up and down.Also have, kept, not only can prevent the trickling down of sorbent in the manufacture process, can also prevent the concave-convex surface of the core 10 that causes by green wood 3 by granular sorbent 5 is dispersed between waste wood layer 6 and the green wood 3.Have again, by sorbent 5 is dispersed in the wide scope, can increase the area of contact between green wood 3 and waste wood layer 6 and the sorbent 5, moisture, gas are adsorbed on the sorbent 5 at an easy rate, its result can stablize the heat-insulating property of Vacuum thermal insulating material 20.
Also have, by sorbent 5 being filled between the fiber that approaches rectangular waste wood 4 and keeping its position, the gas componant in the space between the fiber that remains in its shape and the uneven waste wood 4 of length can be adsorbed, but and the Vacuum thermal insulating material of long term maintenance heat-insulating property can be provided.In addition, also can cut off waste wood 4 and also on green wood 3, be paved with use planely.In this case, though can be paved with the end of green wood 3, and can reduce the concavity and convexity on the surface after making as Vacuum thermal insulating material or finish the deviation of size, but when the waste wood that cuts off during less than 20mm, then the deviation of fiber direction increases and can not stablize the heat-insulating property of Vacuum thermal insulating material 20.
In addition, also can be with above-mentioned waste wood layer 6 as the first waste wood layer, be paved with the thin rectangular waste wood 4 in the residual limit that is produced when making green wood 3 thereon, with as the second waste wood layer.
Have again, owing to put into sorbent 5 before in interior clad material 2, core blank 10A being carried out compression seal, thereby the characterization of adsorption that reduces down of against vacuum decompression, can bring into play adsorptive power effectively.Thus, but moisture that the organic film of hot-melt binding brings into or gas componant etc. can be adsorbed effectively, and the heat-insulating property at initial stage can be stablized.Also have, in general, the against vacuum thermoinsulation material, because moisture or gas enter at leisure by external cladding material, thereby passing deterioration in time worsens heat-insulating property, but, then can control the deterioration of heat-insulating property chronically, and can provide reliability high Vacuum thermal insulating material by using molecular sieve 13X as sorbent 5.
Then, will be in the core blank 10A that waste wood layer 6 and sorbent 5 is clipped in the state that is kept between the green wood 3 up and down, in 200 ℃ kiln furnace dry 10 minutes.This is for by making attached to the water evaporation on green wood 3 and the waste wood layer 6, thereby shortens the vacuum-packed time, and the heat-insulating property of stable Vacuum thermal insulating material 20.
Subsequently, as shown in Figure 4, with core blank 10A be placed on constitute in clad material 2 following film 2a above, and cover above it with the upper film 2b that constitutes interior clad material 2.By pressing plate 8 it is carried out the press machine compression with configuration up and down, thereby the air in squeezing out green wood 3 and waste wood layer 6 and make the thickness of core blank 10A reach the initial stage 50% or it is when following, as shown in Figure 5, the periphery of clad material 2 is the knuckle line part forming sealed department 11 in closing by ripe melten gel, thereby makes core 10.When removing the pressure of pressing plate 8, though core blank 10A will recover original size, because core blank 10A is encased by interior clad material 2 and with the press machine compression and the degassing, therefore, almost do not have air in interior clad material 2 inside, do not expand yet even will recover original size.Therefore, core 10 becomes tabular, the peeling off of part of waste wood layer 6 also can not be taken place, and the Vacuum thermal insulating material 20 that has used the good core of handling property 10 can be provided.
As mentioned above, core blank 10A, but by temporarily compressing, just can be shaped owing to need not to add hot compression etc. with the organic film of hot-melt binding, therefore, the not electricity of consume significant, heat energy, and can alleviate conditioning.Thereby the utilization of the waste wood 4 that constitutes with the above-mentioned inorfil congeries by not containing tackiness agent is complemented each other, and can provide and can realize cutting down electricity, thermal energy consumption significantly and reducing cost, and alleviates the Vacuum thermal insulating material of conditioning.
Have again, aforesaid, with core blank 10A be placed on constitute in clad material 2 following film 2a top and cover operation above it with the upper film 2b that constitutes interior clad material 2, compare with the situation in the interior clad material 2 that inserts the bag shape, the danger that waste wood 4 is trickled down from green wood 3 is few, and operation is good.
Then, with external cladding material 1 cover this compression packing core 10, and carry out vacuum packaging.Before carrying out vacuum packaging, as shown in Figure 5, one side set in advance opening 12 at the interior clad material 2 of core 10.In this first embodiment, vacuumize in the vacuum packaging up to 2.2Pa, when reaching vacuum state and keep vacuum state after 2 minutes, the opening of sealing external cladding material 1.
