Embodiment 2

[0007] Example 2, using metal pigments to prepare a light-shielding liquid, and using aluminum powder as a pigment to prepare a silver-white light-shielding liquid, the formula weight ratio is: silicone oil 89.5-97%, aluminum powder 2%-10%, dispersant 0.5%-1%, silicone oil selection Low-viscosity simethicone oil, fine aluminum powder above 200 mesh is used for aluminum powder, and LS1250 leveling agent produced by Shanghai Liangxing Auxiliary Company is used as dispersant.

Embodiment 3

[0008] Example 3, prepare a light-shielding liquid with non-metallic pigments, such as a black light-shielding liquid prepared with carbon powder for pigments, the formula weight ratio is: 89.5-97% of silicone oil, 2-10% of carbon powder, 0.5%-1% of dispersant, and silicon oil is selected Low-viscosity simethicone oil, carbon powder of any specification used in copiers or laser printers, and dispersant of LS3080 wetting and dispersing agent produced by Shanghai Liangxing Auxiliary Company. The silicone oil and the dispersant should be mixed first, and then the carbon powder should be added for stirring.

[0009] In the above three examples, the shade of color is determined by the amount of colorant in the formula, increasing or decreasing the amount of colorant in the formula can adjust the shade of color;

[0010] Production method: Add the above-mentioned raw materials into a high-speed disperser and stir for 10-15 minutes, and filter with a filter bag above 18 microns to ob...

Abstract

The invention relates to a shading liquid for an automobile windshield. The shading liquid consists of silicone oil, a pigment, a dispersing agent and a surfactant. Colorless silicone oil is selected and used as the silicone oil, a chemical dye or a metal or non-metal pigment which can be dispersed in the silicone oil is adopted as the pigment, and color of the pigment can be one of black, white, red, yellow, blue and green or mutual blended colors of black, white, red, yellow, blue and green; an oil soluble dispersing agent is adopted as the dispersing agent, and an oil soluble surfactant is selected and used as the surfactant.

Description

technical field [0001] The invention discloses a shading liquid used for automobile windshields, belonging to the field of auto parts. technical background [0002] I previously invented a car windshield, application number 200910140127.2, which injects mercury into the closed laminated glass to block light from entering the car. However, mercury has the disadvantages of being volatile, toxic to people and single in color, so it is not perfect as a shading liquid, and there is a need for improvement. Contents of the invention [0003] The object of the present invention is to provide a light-shielding liquid that replaces mercury, thereby eliminating some of the above-mentioned drawbacks. The composition of this shading liquid is composed of silicone oil, colorant and dispersant. The silicone oil used is low-viscosity, non-wall-hanging, and colorless silicone oil; the coloring material is chemical dyes or metal or non-metallic pigments that can be dispersed in silicone o...
