Problems solved by technology

Due to the influence of many factors such as the design, manufacturing and assembly process and materials of the car lamp, it is inevitable that there will be damage at the joint surface between the light distribution mirror and the lamp body, the assembly connection between the lamp and the car body, and the electrical interface. In the case of water or fog, generally we see that the car lights rarely have a drying device, which will have a certain impact on driving safety

Abstract

The invention relates to a drying agent for a vehicle lamp. The drying agent comprises components in parts by mass as follows: 15-18 parts of calcium chloride dehydrate, 28-40 parts of limestone, 25-36 parts of polyacrylamide, 20-24 parts of carbon powder, 10-18 parts of anhydrous cupric sulfate, 8-14 parts of activated carbon and 40-45 parts of water. The drying agent can control the humidity environment in the vehicle lamp, the phenomenon that condensation fog appears in an inner lampshade of the vehicle lamp due to change of the environment temperature when the vehicle lamp is turned on is eliminated, and the probability that steam enters the vehicle lamp is greatly reduced. The inside temperature of the vehicle lamp rises when the lamp is turned on at ordinary times, by means of the characteristic, the drying agent of a breather valve can be activated, and the purpose of prolonging the service life is achieved.

Description

technical field [0001] The invention relates to the technical field of additive preparation, in particular, the invention relates to a desiccant for vehicle lights. Background technique [0002] As an essential component of a car, car lights play an important role in night lighting, traffic signals, fog collision avoidance, turn signs, etc., and are an important guarantee for safe driving. Due to the influence of many factors such as the design, manufacturing and assembly process and materials of the car lamp, it is inevitable that there will be damage at the joint surface between the light distribution mirror and the lamp body, the assembly connection between the lamp and the car body, and the electrical interface. In the case of water or fog, generally we see that the car lights rarely have a drying device, which will have a certain impact on driving safety. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the technical pr...
