Description
Technical field
The utility model relates to Special glasses and makes applied technical field, refers to a kind of work glasses with aerogel heat-proof protective film especially.
Background technology
In electric welder's weld job or the production operation occasion with the close contact of thermal-flame phase, as before converter or utilize flame burn-back glass tube rod etc. Product processing production line on, the a large amount of localized hyperthermias produced during flame combustion can produce baking to the face of operating personnel, easily cause the fatigue of operating personnel with uncomfortable, at the different areas of activity of summer high temperature season or opposing seal, even also can produce the situation of heatstroke, existing protective spectacles great majority become with normal transparent plastic production, non-refractory baking own, simultaneously, the coefficient of heat conductivity of eyeglass is generally between 0.12-0.30w/mk, part infrared heat can be delivered to the eye of operator, cause visual fatigue, if one can be searched out can tolerate localized hyperthermia, the ideal material that lightweight transparent has an effect of heat insulation again covers before glasses, cut off the transmission of infrared ray heat, just can produce good protected effect to staff's eye.
Aerosil is also referred to as blue smoke, solid cigarette, it is the lightest known at present solid material, also be heat-insulating property best material up to now, because it has nano-porous structure (1 ~ 100nm), low-density (3 ~ 250kg/m3), low-k (1.1 ~ 2.5), low thermal conductivity (0.013 ~ 0.025W/(mk)), the feature such as high porosity (80 ~ 99.8%), high-specific surface area (500 ~ 1000m2/g), the character of its uniqueness is demonstrated in thermal insulation etc.
The nano-porous structure of aerogel makes it have splendid heat-insulating property, its thermal conductivity is even also low than air, the thermal conductivity of air under normal-temperature vacuum state is 0.026W/(mk)), and aerogel thermal conductivity is at normal temperatures generally less than 0.020 W/(mk), under the state vacuumized, thermal conductivity can be low to moderate 0.004 W/(mk). it is relevant with its high porosity why aerogel has so good insulation characterisitic.The conduction of heat is mainly through three kinds of approach: gaseous conductance, solid conduction, conduct radiation.In these three kinds of modes, very little by the heat of gaseous conductance, therefore most of gas all has low-down thermal conductivity.Conventional thermal insulation material is all porous structure, make use of a part of volume that air occupies solid material just, thus reduces the thermal conductivity of material monolithic.The porosity of aerogel is more much bigger than conventional insulation material, and it more than 95% is all that air is formed, and determining it will have the thermal conductivity equally low with air.And in aerogel, comprise the hole that a large amount of aperture is less than 70nm, 70nm is the free path assembly average of the distance of process (in the time between gas molecule twice collision) of principal ingredient nitrogen and oxygen in air, also be made up of nano particle, its contact area is very little, and gas thermal conductivity is reduced further.The solid skeletal that in aerogel, content is few is also made up of nano particle; its contact area is very little; aerogel is made to have minimum solid state heat conductance equally; it effectively can stop infrared emanation at normal temperatures; if the transparent heat-insulated performance that can make full use of aerosil is attached to work protective spectacles aspect, will play good heat insulation from protected effect to the eye of staff.
Summary of the invention

The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of work glasses with aerogel heat-proof protective film; fix frame by glass mirror, aerogel rete, resin lens and metal formed; it is characterized in that: after described glass mirror, be pasted with aerogel rete; resin lens is attached after aerogel rete; and the above-mentioned parts fit together being snapped in metal, to fix in frame sealing fixing, make one pair of complete work glasses with aerogel heat-proof protective film.
Described glass mirror adopts the special optical glass plano lens with certain radian, and lens thickness 1mm, refractive index 1.50-1.76, eyeglass surfaces externally and internally is coated with antireflection film layer, transmittance >=96%.
Described aerogel rete adopts aerosil, thickness 1.0-2mm, becomes porosity 98%, the long 50mm of film, the wide 35mm of film, transmittance 94-96%, weighs 0.001 gram.
Described resin lens adopts the resin lens of refractive index 1.56-1.76, and according to the resin lens specifically needing to select zero diopter or be with myopia degree of glasses wearer, the tow sides vacuum evaporation antireflecting film of resin lens, its transmittance is 96-98%.
Described metal is fixed frame and is adopted stainless steel, titanium frame or alloy metal material to make, and is designed to lower frame opening type outside picture frame both sides, to load lower frame and being integrally fixed of upper side frame structure after combined lens with screw.
Method for making of the present utility model, comprises the steps:
1), eyeglass cutting polishing: glass mirror and resin lens cutting are polished into the eyeglass of same specification shape by the size of fixing frame picture frame with reference to metal;
2), lens combination: centre aerogel rete being sandwiched glass mirror and resin lens, paste along the whole circle of lens perimeter fixing with double-sided adhesive band, make above-mentioned eyeglass be fixed into as a whole eyeglass with the bonding combination in aerogel rete outer;
