Problems solved by technology

Generally speaking, filters with different IR protection levels are mainly selected according to the radiation temperature of the ambient heat source. The IR protection level is divided into several categories, such as IR1.3 IR1.5 IR1.7 IR2.0 IR2.5 IR3 IR4 IR5 IR6...IR14, IR3 protective sheet is widely used at present. It has a moderate perspective rate (between 8 and 18.5%) and meets the requirements of the international three standards. However, there is no IR3 protective sheet in the existing literature. Formula, while the IR3 protective sheet on the market is of poor quality and cannot meet the inspection standard of IR3

Embodiment

[0009] Embodiment: A kind of IR green protective lens, comprises polycarbonate PC, IR0001 color powder, 8950 color powder, purple B color powder, 8315 color powder and mixes and makes, and each color powder is Japanese Gadun Pigment Company or Liuhe Chemical Company The production is the raw materials purchased in the existing market, and does not contain heavy metal residues, and will not cause any impact on the human body.

[0010] The following table lists 4 embodiments of the present invention:

[0011]

[0012] As can be seen from the above examples, the present invention is made by adding IR0001 toner, 8950 toner, purple B toner, and 8315 toner in specific proportions to polycarbonate PC, and the spectral test result of the qualified lens is less than 1.2%, and can pass the international three-standard inspection, namely the American standard (ANSIZ80.3:2008), the European standard (EN1836:2005) and the Australian standard (AS / NZS1067:2003), which fully meet the techn...

Abstract

The invention discloses an infrared radiation (IR) green protection eyeglass, and particularly relates to a safety eyeglass with an IR protection infrared function. The eyeglass is prepared by mixing the following components in parts by weight: 100 parts of polycarbonate (PC), 116.2 parts of IR0001 color powder, 12.39 parts of 8950 color powder, 5.41 parts of purple B-color powder and 5.34 parts of 8315 color powder. A certain proportion of IR0001 color powder is added into the PC, and the color powder for filtering visible light is added, so that an IR protection function is realized; and the near infrared (780 to 1,400 nanometers) is less than 1.2 percent.

Description

technical field [0001] The invention discloses an IR green protective lens, which belongs to the technical field of protective eyeglass lens manufacturing according to the International Patent Classification (IPC), and in particular relates to safety glasses that achieve the IR protective function. Background technique [0002] IR protection filter means that in addition to being able to selectively absorb light waves in the visible light (380---780NM) band, it can also protect or filter infrared light (780---2000NM) light sources or radiation sources that cannot be recognized by the naked eye. Spectacle lenses with special protective functions must wear eyepieces with protective functions for effective protection in modern production and life, such as high-voltage arc light, electric welding operations, operations next to high-temperature furnaces, and scientific research laboratories. Generally speaking, filters with different IR protection levels are mainly selected accor...
