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. The formula, especially the IR brown lens, is published in the literature, while the IR3 protective film on the market is of poor quality and cannot meet the inspection standards of IR3

Embodiment

[0009] Embodiment: a kind of IR green protective lens, polycarbonate PC, IR masterbatch, 8970 color powder, 8403 color powder, 8150 color powder are mixed and made, and each color powder is the production of Japan Kadun Pigment Company or Liuhe Chemical Company, It is the raw material purchased in the existing market, and does not contain heavy metal residues, and does 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 polycarbonate PC, IR color masterbatch, 8970 toner, 8403 toner, and 8150 toner to polycarbonate PC in a specific proportion to make qualified lenses. The spectral test result IR (780-2000NM) is less than 12%, 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) The te...

Abstract

The invention discloses an infrared ray (IR) tawny lens, in particular to a safe lens reaching an IR3 infrared protection function. The lens comprises the following ingredients in parts by weight: 100 thousand parts of polycarbonate (PC), 10 thousand parts of IR colorant, one part of 8970 toner, 2.05 parts of 8403 toner and 3.13 parts of 8150 toner. The IR colorant with a given proportion is added in the PC material and then is mixed with the toner capable of filtering the visible light, the protection function of the IR tawny filter plate can be collectively realized, and the spectrum test result shows that the IR (780-2000NM) is less than 12 percent.

Description

technical field [0001] The invention discloses an IR brown 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 with IR brown 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 according to the radia...
