Abstract

The utility model discloses a high performance vacuum insulated panel with compound core material which comprises compound core material. The compound core material comprises wet molding glass fiber core material, dry molding glass fiber core material and silica powder. The wet molding glass fiber core material is positioned in the outermost layer, and the silica powder is set between the wet molding glass fiber core material and the dry molding glass fiber core material. In the utility model the wet molding glass fiber core material and the dry molding glass fiber core material are compound with the hydrophilic silica powder with good water retention, which can absorb some absorbed water in the glass fiber core material that has good adsorption capacity and is difficult to release under atmospheric pressure. The performance deterioration of the vacuum insulated panel is delayer, and the service life is prolonged. The vacuum insulated panel can effectively reduce the energy consumption in the application site, and is energy-saving and environment-friendly.

Description

A kind of high-performance composite core material vacuum heat insulation plate

Technical field

The utility model relates to a kind of thermoinsulation material and thermoinsulation material engineering, is a kind of vacuum heat-insulating plate that adopts composite core material specifically.

Background technique

The energy and environment problem has become worldwide problem, energy saving, the development low-carbon economy extremely urgent.Evacuated insulation panel is a kind of superadiabatic thermal insulating material, in its production and application process, does not use the ODS material, and is nuisanceless to environment.Thermal conductivity can hang down and reach below the 4mW/ (mK), and its thickness can be reduced to 1/3rd of traditional thermal insulating material.Be the best thermal insulating material of present heat-insulating property, have vast potential for future development.

At present, glass fibre core vacuum heat-insulating plate all is that the glass fibre with single dry method or wet production is that core is manufactured.The core unit weight of dry production is little, bulky, is difficult in process of production handle.Though through preheating and drying, desorption slowly still under the high vacuum condition of a part of adsorption type after encapsulation causes the rising of plate internal pressure, the heat-insulating property of reduction VIP to the core of wet production before encapsulation.

The model utility content

The model utility purpose: the purpose of this utility model is in order to overcome the deficiencies in the prior art, provides that a kind of thermal conductivity is low, high insulating effect, the more excellent high-performance composite core material vacuum heat insulation plate of heat-shielding performance.

Technological scheme: in order to solve the problems of the technologies described above, the utility model provides a kind of high-performance composite core material vacuum heat insulation plate, comprise core, described core is a composite core material, comprising: wet glass fibers core, dry method glass fibre core and SiO 2 powder; Described wet glass fibers core is positioned at outermost surface, and SiO 2 powder is between dry method glass fibre core and wet glass fibers core.Adopting SiO 2 powder in the utility model is because the thermal conductivity of silica own is low, and has very strong solid water, with itself and glass fibre core compound after, can heat absorbing glass fiber core after the vacuum heat-insulating plate encapsulation in the part adsorptive power adsorbed water that under normal pressure, is difficult to discharge by force.

Core described in the utility model each layer from top to down is successively in proper order: wet glass fibers core, SiO 2 powder, dry method glass fibre core, wet glass fibers core.

The invention also discloses a kind of production method of high-performance composite core material vacuum heat insulation plate, the step of this method is as follows:

(1) the glass fibre core of dry method, wet production is put into preheating and drying case preheating 5-10 minute, then its taking-up is positioned in the dry environment, form stand-by wet glass fibers core and dry method glass fibre core;

(2) get a wet glass fibers core tiling, get the top that wet glass fibers core and/or dry method glass fibre core are positioned over the wet glass fibers core of the bottom then; Wherein dry method glass fibre core adopts one at least;

(3) between dry method glass fibre core and wet glass fibers core, shed SiO 2 powder;

(4) outermost surface adopts the wet glass fibers core to cover; Finish the making of composite core material;

(5) then with putting into high-isolation film behind the composite core material, high-isolation film is put into vacuum pumping device vacuumize, edge sealing.

Described in the utility model in the core mass ratio between dry method glass fibre core, wet glass fibers core, the SiO 2 powder three be 7:1:2.

Beneficial effect: the utility model compared with prior art has the following advantages:

SiO 2 powder that the utility model is well hydrophilic with solid water and bar method glass fibre core and wet glass fibers core are compound, can effectively alleviate the problem that core residual adsorbed water in vacuum heat-insulating plate encapsulation back causes the plate internal pressure to raise after volatilization, delayed the degeneration of vacuum heat-insulating plate performance, prolonged working life, can effectively reduce the energy consumption of its application, accomplish energy-conserving and environment-protective.

Description of drawings

Fig. 1 is the structural representation of core in the utility model.

Embodiment

Below in conjunction with specific embodiment, further illustrate the utility model, should understand these embodiments only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims to the modification of the various equivalent form of values of the present utility model and limit.

Embodiment

A kind of high-performance composite core material vacuum heat insulation plate comprises core, and this core is composite core material (as shown in Figure 1), comprising: wet glass fibers core 1, dry method glass fibre core 2 and SiO 2 powder 3; In the present embodiment, wet glass fibers core 1 is two-layer, and dry method glass fibre core 2 is one deck, and SiO 2 powder 3 is one deck; This composite core material each layer from top to down is successively in proper order: wet glass fibers core, SiO 2 powder, dry method glass fibre core, wet glass fibers core.

Present embodiment also provides the production method of above-mentioned high-performance composite core material vacuum heat insulation plate, and the step of this method is as follows:

(1) the glass fibre core of dry method, wet production is put into preheating and drying case preheating 8 minutes, then its taking-up is positioned in the dry environment, form stand-by wet glass fibers core and dry method glass fibre core;

(2) get a wet glass fibers core tiling, get the top that wet glass fibers core and/or dry method glass fibre core are positioned over the wet glass fibers core of the bottom then; Wherein dry method glass fibre core adopts one at least;

(3) between dry method glass fibre core and wet glass fibers core, shed SiO 2 powder;

(4) outermost surface adopts the wet glass fibers core to cover; Finish the making of composite core material; Shown in dry method glass fibre core in the composite core material: the wet glass fibers core: the mass ratio between the SiO 2 powder three is 7:1:2;
