Description
Technical Field
The invention relates to the technical field of heat-insulating felts, in particular to a silicon-based nano-pore heat-insulating felt.
Background
The concept of super insulation (Superinsulation) was proposed in the United states at the International society for materials engineering in 1992 and refers to an insulation material that has a thermal conductivity that is lower than the thermal conductivity of "still air" under certain conditions of use. The silica aerogel material has a large number of nano pores, more than 85% of the pores have diameters smaller than 50nm, the mean free path of oxygen and nitrogen molecules in the air is about 70nm, and when the diameters of the pores are smaller than the mean free path of the gas, the air molecules can be regarded as 'static', thereby effectively eliminating the convection heat transfer of the gas, and meanwhile, the solid phase heat transfer of the silica aerogel material is limited due to the ultrahigh porosity. Due to the unique structure of the silicon dioxide aerogel, the silicon dioxide aerogel has excellent heat insulation performance, but the porous framework of the silicon dioxide aerogel also causes the defects of low strength, small toughness, poor mechanical property and unstable structure of the aerogel material.
Disclosure of Invention
The invention aims to provide a silicon nano-pore heat-insulating felt so as to improve the strength of silicon dioxide aerogel.
In order to solve the technical problems, the invention provides the following technical scheme: the utility model provides a silicon is adiabatic felt of nanometer hole heat preservation, includes silica aerogel layer, the upper surface and the lower surface of silica aerogel layer all are equipped with ceramic fiber net, and are two-layer ceramic fiber net adopts the quilting treatment, the aluminium foil tape has evenly been laid on ceramic fiber net's surface, the surface of aluminium foil tape is laid and is used the non-woven fabrics, the non-woven fabrics adopts the quilting treatment.
The working principle of the invention is as follows: this scheme is through laying ceramic fiber net at silica aerogel's upper surface and lower surface, firstly ceramic fiber net has high temperature resistant equally, the characteristic that coefficient of heat conductivity is low, it has certain pull resistance simultaneously, consequently, wrap up silica aerogel through the mode of quilting treatment, consequently, the pull resistance through ceramic fiber net is used for strengthening silica aerogel layer's pull resistance, then evenly lay the aluminium foil sticky tape on ceramic fiber net's surface, paste the surface at ceramic fiber net through the aluminium foil sticky tape, further increase tensile strength. Simultaneously the aluminium foil sticky tape has the effect of reflection heat radiation, can strengthen the thermal-insulated effect of heat preservation of silica aerogel layer, and the non-woven fabrics through having the fireproof effect is wrapped up the quilting to the silica aerogel who pastes and have the aluminium foil sticky tape at last and is handled, and the last whole that obtains one and has higher strength, and toughness is stronger, and the pull resistance also obviously increases.
Furthermore, a plurality of through holes are uniformly distributed on the aluminum foil adhesive tape. Its purpose makes silica aerogel when being heated through this kind of setting, avoids the aluminium foil sticky tape to form airtight space, causes its inside air thermal expansion.
Furthermore, the aperture of the through hole is 0.1-0.3 mm. Its purpose is to ensure air permeability below this pore size.
Further, the edges of the aluminum foil tape do not overlap. The purpose is to ensure the laying uniformity of the aluminum foil adhesive tape and ensure the surface smoothness.
Furthermore, waterproof layers are uniformly laid on the inner surfaces of the non-woven fabrics. The purpose is to avoid the heat insulation felt from being wetted by water through the arrangement.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of a thermal insulation felt with silicon-based nano-pores according to the present invention.
Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: non-woven fabrics 1, aluminum foil adhesive tapes 2, ceramic fiber nets 3 and silica aerogel layers 4.
The embodiment is basically as shown in the attached figure 1:
the utility model provides a silicon is adiabatic felt of nanometer hole heat preservation, includes silica aerogel layer 4, the upper surface and the lower surface of silica aerogel layer 4 all are equipped with ceramic fiber net 3, two-layer ceramic fiber net 3 adopts the quilting treatment, aluminium foil adhesive tape 2 has evenly been laid on ceramic fiber net 3's surface, and the edge of aluminium foil adhesive tape 2 does not overlap, and the equipartition has a plurality of through-holes on the aluminium foil adhesive tape 2, and the aperture of through-hole is 0.1 ~ 0.3mm (preferred 0.2mm), non-woven fabrics 1 is laid on aluminium foil adhesive tape 2's surface, non-woven fabrics 1 adopts the quilting treatment, and the waterproof layer has evenly been laid to non-woven fabrics 1's internal surface.
The specific implementation process is as follows:
ceramic fiber net 3 is laid through upper surface and lower surface at silica aerogel to this scheme, ceramic fiber net 3 has high temperature resistant equally, the characteristic that coefficient of heat conductivity is low, it has certain pull resistance simultaneously, consequently, wrap up silica aerogel through the mode of quilting treatment, consequently, the pull resistance through ceramic fiber net 3 is used for strengthening silica aerogel layer 4's pull resistance, then evenly lay aluminium foil sticky tape 2 on ceramic fiber net 3's surface, paste the surface at ceramic fiber net 3 through aluminium foil sticky tape 2, further increase tensile strength. Simultaneously aluminium foil sticky tape 2 has the effect of reflection heat radiation, can strengthen the thermal-insulated effect of heat preservation of silica aerogel layer 4, wraps up the quilting through the non-woven fabrics 1 that has the fire prevention effect to the silica aerogel who pastes and have aluminium foil sticky tape 2 at last and handles, obtains one at last and has higher strength, and toughness is stronger, and the whole that the pull resistance also obviously increased. If the inside air of silica aerogel is heated the inflation at the in-process that insulates against heat, then can discharge through the through-hole on the aluminium foil sticky tape 2, avoid its inside air to be heated the inflation.
