Problems solved by technology

Based on this, in order to avoid danger, automobile anti-glare technology has appeared in the automobile industry. At present, anti-glare devices with photoelectric integrated systems are mostly used in the field of automobile anti-dazzle. The principle and characteristics make its production process complicated, requiring the cooperation of multiple systems such as light collection, intelligent processing, liquid crystal control and drive system, and light-transmitting screen to prevent strong light from entering the driver's process and knowledge combination in multiple fields, and the product cost is high and installation is difficult. Larger and other deficiencies
Most of the colored glass produced by adding light absorbers in the plexiglass production process is colored glass, because the light absorbers themselves have selective light absorption characteristics, resulting in low light transmittance and cannot meet the light requirements for low-light driving at night , so it cannot be used for nighttime anti-glare equipment

Embodiment 1

[0019] Weigh 10 g of 2-(2'-hydroxyl-5'-methylphenyl)benzotriazole, tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]pentaerythritol 10g, 80g of samarium borate, mixed with dichloromethane and dissolved to form a solution, 1 / 2 of the obtained solution was evenly sprayed on 25.8Kg plexiglass particles, melted, cooled and granulated, and then the remaining 1 / 2 of the solution was evenly sprayed on the On granulation, melting, cooling and granulation, extrusion method to produce plate-shaped plexiglass, and polishing treatment, the transmission and filtration of target light is 0.65%. See Table 1 for details.

Embodiment 2

[0021] Weigh 15g of 2-(2'-hydroxyl-5'-methylphenyl)benzotriazole, tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]pentaerythritol ester 15g, 70g of samarium borate, mixed with dichloromethane and dissolved to form a solution, 1 / 2 of the obtained solution was evenly sprayed on 16.6Kg plexiglass particles, melted, cooled and granulated, and then the remaining 1 / 2 of the solution was evenly sprayed on the On granulation, melting, cooling and granulation, extruding method to produce plate-shaped organic glass, and polishing treatment, the transmission and filtration of target light is 0.33%. See Table 1 for details.

Embodiment 3

[0023] Weigh 20 g of 2-(2'-hydroxyl-5'-methylphenyl)benzotriazole, tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid]pentaerythritol ester 20g, 60g of samarium borate, mixed with dichloromethane and dissolved to form a solution, 1 / 2 of the obtained solution was evenly sprayed on 11.7Kg plexiglass particles, melted, cooled and granulated, and then the remaining 1 / 2 of the solution was evenly sprayed on the On granulation, melting, cooling and granulation, extrusion method to produce plate-shaped organic glass, and polishing treatment, the transmission and filtration of target light is 0.26%. See Table 1 for details.

[0024]

[0025] Table 1

[0026]

[0027] It can be seen from Table 1 that the product of the present invention can effectively prevent the transmission of glare light, the transmittance is only 0.26% to 0.65%, the product performance is stable, and the anti-glare effect is good.

Abstract

The invention discloses a light absorber, filter glass prepared from the light absorber and a method for preparing the filter glass from the light absorber. The light absorber is prepared by mixing 2-(2'-hydroxy-5'-methphenyl)benztriazole, pentaerythrite tetra[beta-(3,5-di-tert-butyl-4-hydroxyphenyl)-propionate] and samarium borate, and is used for preparing organic glass and the filter glass. The light absorber provided by the invention and the filter glass prepared from the light absorber have a remarkable anti-dazzling effect; and simultaneously the preparation method has the advantages of simplicity, novel design, low cost and the like.

Description

technical field [0001] The invention relates to a light absorber, a filter glass made of the same and a method for preparing the filter glass. Background technique [0002] Dazzling is an unavoidable problem in the process of driving, especially in the process of meeting cars at night, the driver's eyes are temporarily blinded due to the strong light of the oncoming car, and it takes several seconds to tens of seconds for the vision to recover. During the period, the driver is equivalent to "blind driving". 48.6% of night driving accidents are caused by glare and short-term blindness due to strong light, and driving out of control. Based on this, in order to avoid danger, automobile anti-glare technology has appeared in the automobile industry. At present, anti-glare devices with photoelectric integrated systems are mostly used in the field of automobile anti-dazzle. The principle and characteristics make its production process complex, requiring the cooperation of multiple...
