Color rubber for wireless charger pads with anti-discoloration effects in natural conditions

摘要

The present invention relates to a color rubber for a wireless charger pad having an effect of preventing discoloration in a natural state, and is characterized by comprising synthetic rubber, paraffin oil, carbon black, sunscreen, anti-aging agent, and anti-rainbow agent. In addition, the method for producing a color rubber for a wireless charger pad having an effect of preventing discoloration in a natural state is a primary mixing step of mixing 40 to 60 parts by weight of paraffinic oil and 10 to 30 parts by weight of carbon black with respect to 100 parts by weight of synthetic rubber. And, a sunscreen agent, an anti-aging agent and a rainbow inhibitor are mixed in the rubber mixture mixed in the first mixing step, with respect to 100 parts by weight of the synthetic rubber, 5 to 15 parts by weight of a sunscreen, 5 to 10 parts by weight of an anti-aging agent and A secondary mixing step of mixing 3 to 7 parts by weight of a rainbow inhibitor, an aging step of aging the rubber mixture mixed in the second mixing step, a cutting step of cutting the rubber mixture aged in the aging step, and the cutting step It characterized in that it comprises a molding step of heating the cut rubber mixture in a molding vulcanizer at a pressure of 10 to 20 bar and a temperature of 170 to 200 ℃ for 3 to 5 minutes. According to the present invention, it can be used in various environments such as indoors, outdoors and vehicles through suitable additives considering the physical and chemical properties of synthetic rubber. It prevents appearance defects such as surface discoloration and whitening, promotes user convenience, and can be used semi-permanently.
