A kind of black pigment applied to remote control receiving panel and its preparation method

Abstract

The invention discloses a black coloring material applied to a remote control receiving panel and a preparation method thereof, wherein the black coloring material comprises the following raw material components in parts by weight: 2500 parts of plastic substrate; 1-100 parts of blue coloring agent; 1-50 parts of red coloring agent; 1-50 parts of yellow coloring agent; 1-50 parts of red coloring agent; and 5-300 parts of dispersing agent; wherein the blue coloring agent is blue pigment or blue dye; The purple pigment or purple dye; the yellow colorant is yellow pigment or yellow dye; the red colorant is red pigment or red dye; the black colorant is granular or powdery. The black colorant of the present invention is prepared by mixing various blackening pigments or dyes into a transparent or translucent black colorant, which has the advantage of low absorption rate of far-infrared rays. The black colorant of the present invention is applied to electrical appliances or remote controls The remote control black translucent panel can greatly improve the remote control distance.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a black pigment applied to a remote control receiving panel and a preparation method thereof. Background technique [0002] With the development of science and technology, the existing electrical appliances generally have remote control function. The remote control uses the remote control principle of far infrared rays to remotely control the operation of electrical appliances, such as set-top boxes, fans, air conditioners and other household appliances. The electrical appliances are used to receive signals and indicator lights. The position is generally protected by a black translucent panel, and the signal transmitting part on the remote control is also protected by a black translucent panel. On the one hand, the color of the indicator light (such as red light and green light, etc.) can be highlighted through the black translucent panel; structure, thereby improving the aesth...

AI Technical Summary

Problems solved by technology

However, the penetration rate of far-infrared rays on the black translucent panel is low. Therefore, the effective distance of the remote control of home appliances is short, generally within 5 meters, and the 5-meter remote control range can only be used at home. When remote control, the user needs to hold the remote control to enter the 5-meter remote control range of the home appliance to operate, which is extremely inconvenient to use
