Abstract

The invention discloses a color master batch for improving light transmittance display, a preparation method and application, and belongs to the technical field of functional master batches. The color master batch for improving light transmittance display is prepared from, by weight, 30-40% of a filling, 10-20% of additives and the balance carrier resin. The color master batch is applied to a panel display window, can make LED lamp characters displayed clearly, and does not affect the range of infrared receiving; the technical problem is solved that LED characters or patterns become blurred after being magnified, and the LED lamp characters or patterns can be displayed in the same proportion on a display window panel, and will not become blurred; the brightness of the display panel is increased; the application range of remote control infrared receiving will not be affected, the preparation method is simple, the made display window panel can be prevented from generating flow lines, the surface of the panel is smooth and flat, and the range of remote control infrared receiving is larger than 15 meters. In order to improve production efficiency and reduce losses, the original display window of a mold is changed from the thickness of 1.2 mm to the thickness of 1.5-3 mm, and the technology and efficiency meet requirements.

Description

technical field [0001] The invention relates to the technical field of functional masterbatches, in particular to a color masterbatch for improving light transmission display, a preparation method and an application thereof. Background technique [0002] Window materials (window materials) can be used to isolate the external environment, protect internal devices, and have a high transmittance to light of a specific wavelength or range of wavelengths, and play the role of a window. Window materials are required to have physical properties such as high optical transmittance, high hardness, good erosion resistance, small thermal expansion coefficient, and low absorption loss. [0003] The display window of the air conditioner is used to display the operating mode of the air conditioner, and the different operating states of the air conditioner are indicated by the bright display. At present, because the thickness of the display window is very small, only about 1.2mm, there wil...
