Embodiment Construction

[0020] refer to figure 1 , a kind of work glasses with airgel heat-insulating protective film layer, is made up of glass lens, airgel film layer, resin lens and metal fixed spectacle frame, is characterized in that: described glass lens is attached with air Gel film layer, resin lens is attached to the back of the airgel film layer, and the above-mentioned parts that are pasted together are snapped into the metal fixed spectacle frame to seal and fix, and a complete pair of airgel heat-insulating protective film layer is made work glasses. The glass lens adopts a special optical glass plano lens with a certain radian, the thickness of the lens is 1 mm, and the refractive index is 1.50-1.76. The airgel film layer is made of silica airgel, with a film thickness of 1.0-2 mm, a porosity of 98%, a film length of 50 mm, a film width of 35 mm, a light transmittance of 94-96%, and a weight of 0.001 g. The resin lens adopts a resin lens with a refractive index of 1.56-1.76. According...

Abstract

The invention provides a pair of working spectacles provided with aerogel thermal insulation protective film layers and a preparation method of the working spectacles. The pair of working spectacles comprises glass lenses (1), aerogel film layers (2), resin lenses (3) and a metal fixing spectacle frame (4) and is characterized in that the aerogel film layers (2) are attached to the rear sides of the glass lenses (1), the resin lenses (3) are attached to the rear sides of the aerogel film layers (2), the attached components are clamped into the metal fixing spectacle frame (4) to be sealed and fixed, and a complete pair of working spectacles provided with the aerogel thermal insulation protective film layers is prepared. By means of the working spectacles, the operation time at the high temperature can be prolonged on a high-temperature site where an infrared heat source is used, and meanwhile, the hidden danger of eye injury due to overheating is avoided. The working spectacles have the characteristics of novel innovation, advanced technology, simplicity and convenience in preparation and high practicability.

Description

technical field [0001] The invention relates to the technical field of production and application of special glasses, in particular to work glasses with an airgel heat-insulating protective film layer and a manufacturing method thereof. Background technique [0002] In the welding operation of electric welders or production operations in close contact with high-temperature flames, such as in front of steelmaking furnaces or on the production line for processing products such as glass tubes and rods with flames, a large number of local high temperatures generated during flame combustion will affect the safety of workers. The face is baked, which is easy to cause fatigue and discomfort of the operator. In the high temperature season in summer or in a relatively sealed workplace, it may even cause heat stroke. Most of the existing protective glasses are made of ordinary transparent plastics. It is resistant to high temperature baking. At the same time, the thermal conductiv...
