Problems solved by technology

Although the performance of the mouse pads on the market is generally relatively mature, the movement of the photoelectric mouse is positioned by the light emitted from the bottom of the mouse and then reflected by the mouse pad back to the light sensor inside the photoelectric mouse for positioning. The efficiency of the mouse pad to the reflected light of the photoelectric mouse is not high, so it limits the practical application of the photoelectric mouse

Abstract

The invention belongs to the technical field of colloidal crystal materials and specifically relates to colloidal crystal paint. According to the colloidal crystal paint, water-soluble carbon black isutilized to enhance reflected light intensity of colloidal crystal. The invention further discloses application of the colloidal crystal paint to prepation of the mouse pad. The colloidal crystal paint disclosed by the invention is prepared by mixing copolymer microballoon emulsion with the water-soluble carbon black. The water-soluble carbon black is favorable for enhancing the reflected light intensity of colloidal crystal, so that the colloidal crystal paint is suitable for preparing photoelectric mouse pads. The photoelectric mouse pad is covered by the colloidal crystal paint disclosed by the invention to form a light reflecting layer; according to a mouse movement speed test, a movement speed of a photoelectric mouse on the mouse pad coated with the colloidal crystal paint is higherthan that of the photoelectric mound on a mouse pad not coated with the colloidal crystal paint. Therefore, the colloidal crystal paint disclosed by the invention is favorable for improving the reflected light intensity of the mouse pad and can improve the mouse movement speed.

Description

technical field [0001] The invention belongs to the technical field of colloidal crystal materials, and in particular relates to a colloidal crystal coating. The colloidal crystal coating utilizes water-soluble carbon black to enhance the reflected light intensity of colloidal crystals, and further discloses its application for preparing mouse pads. Background technique [0002] Colloidal crystals are a class of substances with three-dimensional ordered structures formed by monodisperse micron or submicron inorganic or organic particles. In the three-dimensional ordered structure of colloidal crystals, the repeating period is on the order of micrometers and submicrometers, and visible light (400-700nm) can undergo Bragg diffraction in it, making it present different colors. In the past few decades, the study of the optical properties of colloidal crystals has received high attention. [0003] At present, the application fields of colloidal crystals are very extensive, and r...
