Model utility content
The technical problems to be solved in the utility model is to provide a kind of aluminum foil composite heat shroud.
For solving the problems of the technologies described above, the utility model about the technological scheme of aluminum foil composite heat shroud is: it makes the bottom of heat shroud by high-temperature heat insulation cloth, described high-temperature heat insulation cloth has overlap edge in the corner of instrument and apparatus, be coated with at the outer surface of high-temperature heat insulation cloth and be brushed with continuous print adiabatic coating layer, end face that is outer at this adiabatic coating layer and heat shroud is coated with layer of varnish, has aluminium foil composite adiabatic film at this layer of varnish external pasting.
Further, described heat shroud is provided with stop hole and lacing hole, and running through in described lacing hole has stainless steel glass cord.
Preferably, described high-temperature heat insulation cloth thickness is 0.3mm, and the thickness of the adiabatic coating layer on described high-temperature heat insulation cloth is 2.0-3.0mm.
Preferably, described adiabatic coating layer is polyurethane adiabatic coating layer.
The utility model, about the making method of the heat shroud of heatproof Low emissivity time long, comprises following process step: 1. make mould; 2. make the bottom of heat shroud of high-temperature heat insulation cloth according to mould; 3. at the outside brushing adiabatic coating of high-temperature heat insulation cloth and baking-curing; 4. rush stop hole and lacing hole according to drawing in heat shroud predetermined portion, crack; 5. the end face lacquer varnish of and heat shroud outer at adiabatic coating layer baking-curing; 6. on layer of varnish, paste aluminium foil composite adiabatic film; 7. lacing hole is run through with stainless steel glass cord.
3. described step is brush brush polyurethane adiabatic coating at the outer surface palm fiber of high-temperature heat insulation cloth, each brushing paint about thickens 0.03-0.06mm, after brushing, product is placed in temperature 25 ± 5 DEG C, relative moisture dries naturally lower than in the room of 65%, time is 10-15 minute, again the product naturally dried is placed in 120 DEG C of electric heating casees and toasts 40-60 minute, coating is solidified completely, then carry out brushing next time and solidification, so repeatedly make whole coating thickness reach 2.0-3.0mm.
The varnish that described step is 5. sprayed is chlorosulfonated polyethylene varnish, toasts 30-40 minute under the protecting cover of lacquer varnish being placed on 100-120 DEG C of temperature environment, ensures that chlorosulfonated polyethylene is varnish curing.
Adopt the utility model making method to produce long time heatproof Low emissivity heat shroud, easy for installation, shaping conformability is good, protection effect is stablized, can 152KW/m
2keep 73 seconds under heat-flux conditions, in heat shroud, instrument, instrument surface temperature are lower than 35 DEG C.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model aluminum foil composite heat shroud.
Embodiment
As shown in Figure 1, the utility model about the preferred embodiment of aluminum foil composite heat shroud is: the bottom being made up heat shroud of the high-temperature heat insulation cloth 2 that 0.3mm is thick is wrapped on mould 1, described high-temperature heat insulation cloth 2 has overlap edge in the corner of instrument and apparatus, be coated with at the outer surface of high-temperature heat insulation cloth 2 and be brushed with continuous print, thickness is the polyurethane adiabatic coating layer 3 of 2.4mm, end face that is outer at polyurethane adiabatic coating layer 3 and heat shroud is coated with layer of varnish 4, aluminium foil composite adiabatic film 5 is had at this layer of varnish 4 external pasting, described heat shroud is provided with stop hole and lacing hole, run through in described lacing hole and have stainless steel glass cord.
The utility model comprises following process step about the making method of the heat shroud of heatproof Low emissivity time long:

(7) baking-curing
Naturally the product dried is placed in 120 DEG C of electric heating casees and toasts 40-60 minute, product is solidified completely, avoid because the time limit produces the phenomenon that is clamminess; Step (5)-(7) repeatedly, make the total thickness of polyurethane adiabatic coating layer reach 2.4mm;
(8) repair, clean
Surface treatment is carried out to product inner and outer surface, rejects fifth wheel;
(9) according to drawing requirement setting-out, be cut to given size, rush stop hole and lacing hole according to drawing in predetermined portion, crack;
(10) spray chlorosulfonated polyethylene varnish, utilize its good resistance, stop steam to the corrosion of product, ensure that product is not clamminess under 5 years particular surroundingss; (11) at 100-120 DEG C of temperature, baking 30-40min ensures that chlorosulfonated polyethylene is varnish curing;
(12) on layer of varnish, paste aluminium foil composite adiabatic film;
(13) run through lacing hole with stainless steel glass cord by drawing, long position binding is agglomerating, unties during installation.
