Description
Technical field
The utility model relates to a kind of heat insulating material, refers in particular to a kind of heat insulating material with vacuum heat-insulating plate.
Background technology
Vacuum heat-insulating plate (Vacuum Insulation Panel is called for short VIP) is the new and effective thermal insulation material of one that development in recent years is got up.The sack that it is normally made up of gas barrier film, core and the getter that thermal insulation material forms form, and by getter with fill core and pack in the sack that gas barrier film makes, then the sack that gas barrier film is made is evacuated and makes it sealing.Gas barrier film can make maintenance vacuum state in this sack, and the heat transmission of effectively avoiding cross-ventilation to cause, with extraneous adiabatic.But, because VIP itself is flexible rectangular plate shape thing, on thickness direction the Area comparison of two relative first type surfaces large, the area of four sides of periphery is all very little, while taking up, is easy to make two first type surface flexural deformations; Gas barrier thin film thickness, two first type surfaces are relatively frangible.In addition, the sack that gas barrier film is made in production or use procedure is easily pierced or breaks, the defective locations that the gases such as nitrogen, oxygen, carbon dioxide, hydrogen and water vapour can see through gas barrier film is penetrated into VIP inside, affects the application life of VIP.
For these two problems, a kind of thermal insulating panel composite has been proposed in Chinese patent CN102482446, wherein limit a kind of extruded thermoplastic polymer foam that has cavity, and vacuum insulation panel is placed in its cavity completely.Protect the VIP in its cavity by extruded thermoplastic polymer foam, so that optimized barrier properties for gases and intensity to be provided.But extruded thermoplastic polymer foam thermal conductivity is higher, cannot meet actual user demand.
Utility model content
The utility model aims to provide a kind of thermal insulation thermal insulation board, not only makes VIP exterior mechanical intensity be strengthened, and improves the life-span of VIP.
The technical solution of the utility model is: a kind of thermal insulation thermal insulation board, comprises porous foam body and flexible vacuum heat-insulating plate; This porous foam body is that density is hard polyurethane foam or the phenolic resin foam of 40-80 kilograms per cubic meter, and this porous foam body directly and at least one first type surface of this vacuum heat-insulating plate and all lateral junction be integrated; In this porous foam body, the yardstick of each abscess is less than 0.3 millimeter and rate of closed hole and is greater than 60%; This porous foam body is 1.0-7.5 millimeter at the thickness in this vacuum heat-insulating plate first type surface outside.
Polyurethane (English polyurethane by name, referred to as PU, full name is polyurethanes) is the general designation that contains the macromolecular compound of repetition carbamate groups on main chain.Hard polyaminoester is rigid material wherein, hard polyurethane foam has insulation and waterproof dual-use function, and its coefficient of thermal conductivity is low, only 17～24mW/m Κ, being equivalent to the half of extruded thermoplastic polymer foam, is that in current foaming thermal-insulating, coefficient of thermal conductivity is minimum.
Phenolic resins (English Phenol Formaledlyde by name, is called for short PF), phenolic resin foam also has insulation and waterproof dual-use function, and its about 23-28mW/mk of coefficient of thermal conductivity is slightly high compared with hard polyurethane foams.But in the time that environment for use temperature is higher, temperature tolerance, higher than hard polyurethane foam, is difficult for shrinkage strain, insulation longer service life.
Fig. 1 illustrates that inventor research institute obtains the relation curve of hard polyurethane foam density and coefficient of thermal conductivity.As shown in Figure 1, hard polyurethane foam density is in 40-80 kilograms per cubic meter (kg/m3) coefficient of thermal conductivity and optimal stability thereof, and now hard polyurethane foam rate of closed hole is greater than 95%.Hard polyurethane foam coefficient of thermal conductivity and rate of closed hole, aperture, hole composition of gases within are in close relations.Current production technology is in the situation that foaming condition is identical, density is low lower than the hard polyurethane foam rate of closed hole of 40 kilograms per cubic meter, and it is more that yardstick is more than or equal to the large abscess of 0.3 millimeter, and bubble wall is thin, gas easily sees through, and makes material monolithic coefficient of thermal conductivity higher.Fig. 2 illustrates that inventor research institute obtains the relation curve of phenolic resin foam density and coefficient of thermal conductivity.As can be seen from Figure 2, when phenolic resin foam density is lower than 30 kilograms per cubic meter (kg/m
3), phenolic resin foam coefficient of thermal conductivity is higher, and it is discrete to distribute.Density is generally selected 60-80 kilograms per cubic meter, and coefficient of thermal conductivity is lower and stable with this understanding.Phenolic resin foam density is too high, and on coefficient of thermal conductivity, impact is not obvious especially, and consumption of raw materials is higher, so phenolic resin foam optimal foaming density is selected 60-80 kilograms per cubic meter.
So coefficient of thermal conductivity is low and material consumption is few when above-mentioned porous foam bulk density is 40-80 kilograms per cubic meter.In the situation that foaming condition is identical, the density of above-mentioned porous foam body is too low, illustrates that the yardstick of inner each abscess is large, intensity and the toughness deficiency of entirety, and inner each abscess easily breaks and runs through, and causes inner air to produce convection current, and coefficient of thermal conductivity rises fast; Above-mentioned porous foam bulk density is too high, although the yardstick of inner each abscess has reduced, raw materials consumption is large, again the raising of rate of closed hole is not had to effect, thereby the reduction of coefficient of thermal conductivity is not had to effect; And the excessive porosity that has also reduced self of above-mentioned porous foam bulk density, thus the solid heat transfer coefficient of above-mentioned porous foam body itself increased, thermal insulation thermal insulation board overall thermal conductivity is improved.
Show through inventor research, porous foam body thickness above-mentioned outside vacuum heat-insulating plate first type surface is larger, and the effect that vacuum heat-insulating plate plays in this thermal insulation thermal insulation board is just little; Because above-mentioned porous foam body coefficient of thermal conductivity is higher than vacuum heat-insulating plate, be approximately 10 times of vacuum heat-insulating plate.Two above-mentioned thermal insulation thermal insulation boards with vacuum heat-insulating plate that integral thickness is identical, wherein thicker its coefficient of thermal conductivity of vacuum insulation plate thickness is lower, and heat-insulating property is higher.So; above-mentioned porous foam body thickness should do thin as far as possible; as long as porous foam body good toughness; in vacuum heat-insulating plate use procedure, can play protective gas Obstruct membrane is not punctured; the effect of pulling; the less leakage rate of protection vacuum heat-insulating plate, its basic goal is in order to reduce vacuum heat-insulating plate plate internal gas pressure climbing speed, prevents that the vacuum decline in vacuum heat-insulating plate from affecting the overall thermal conductivity energy of thermal insulation thermal insulation board.
Show through inventor's research, in the time that the above-mentioned porous foam body thickness in vacuum heat-insulating plate first type surface outside is less than 1.0 millimeters, foam is poor in mould internal mobility, causes foaming uneven, bad mechanical strength.In the time that above-mentioned porous foam body thickness is greater than 7.5 millimeters, not only need to consume more raw material, cost is higher, and thermal conductivity also can increase.
Fig. 3 illustrates that inventor research institute obtains hard polyurethane foam in the time that the thickness in the upper and lower first type surface of vacuum heat-insulating plate outside equates, select the hard polyurethane foam of density 53 kilograms per cubic meter that vacuum heat-insulating plate is completely coated, the inner stuffing of vacuum heat-insulating plate is glass fiber, barrier bag is the conventional barrier bag of the VIP of same batch, aging for accelerating vacuum heat-insulating plate, in vacuum heat-insulating plate, do not add gettering material.Vacuum insulation plate thickness is 11 millimeters, the above-mentioned thickness of hard polyurethane foam is selected respectively 1 millimeter, 2 millimeters, 3.5 millimeters and 5.5 millimeters, aging temperature is 145 DEG C, ageing time 90 days, characterize the ageing-resistant performance of vacuum heat-insulating plate with the coefficient of thermal conductivity of this thermal insulation thermal insulation board, the relation curve of the above-mentioned thickness of hard polyurethane foam and the overall thermal conductivity of this thermal insulation thermal insulation board.As shown in Figure 3, the above-mentioned thickness of hard polyurethane foam is larger, and this thermal insulation thermal insulation board overall thermal conductivity is higher; The above-mentioned thickness of hard polyurethane foam is too low, and vacuum heat-insulating plate is aging too fast; It is preferred plan that the above-mentioned thickness of hard polyurethane foam is chosen in 2-3.5 millimeter.
Fig. 4 illustrates that inventor research institute obtains ageing-resistant performance that the coated vacuum heat-insulating plate of hard polyurethane foam and the coated vacuum heat-insulating plate of phenolic resin foam characterize vacuum heat-insulating plate with coefficient of thermal conductivity in heat resistant difference.Wherein, two kinds of porous foam bodies are 3 millimeters at the thickness in the upper and lower first type surface of vacuum heat-insulating plate outside, and the thickness of vacuum heat-insulating plate is 11 millimeters, and aging temperature is 145 DEG C, ageing time 90 days.From this coefficient of thermal conductivity change profile, figure can find out, the coated high temperature resistant longer service life of vacuum heat-insulating plate of phenolic resin foam is of a specified duration.Because hard polyurethane foam resistance to elevated temperatures is poor, so the coated vacuum heat-insulating plate of hard polyurethane foam is mainly used in normal temperature or low temperature environment.
The utility model is directly coated flexible vacuum heat-insulating plate by the hard polyurethane foam or the phenolic foams that use density to be greater than 60% for the yardstick of 40-80 kilograms per cubic meter, each abscess is less than 0.3 millimeter and rate of closed hole, be 1.0-7.5 millimeter at the thickness in this vacuum heat-insulating plate first type surface outside, can make flexible vacuum heat-insulating plate exterior mechanical intensity be strengthened, become the thermal insulation thermal insulation board with vacuum heat-insulating plate of rigidity; Porous foam body is not easy aging delamination, thereby has extended the application life of vacuum heat-insulating plate.
Implement in structure preferred: described porous foam body is 1.5-2.5 millimeter at the thickness in this vacuum heat-insulating plate first type surface outside.Carry out comprehensively from cost, protection intensity and thermal conductivity three aspects:, the porous foam body of this thickness is optimum selection.
And then: the surface coverage rigidity decorative material layer that described porous foam body is relative with described vacuum heat-insulating plate first type surface.
