Abstract
The present invention relates to a cleaning liquid composition, particularly provides a cleaning liquid composition for a glass substrate, wherein the cleaning liquid composition is designed for the glass substrate, has characteristics of strong cleaning capability and excellent antifoaming performance, and does not easily erode the substrate, wherein the surface roughness of the substrate is increased due to the substrate eroding. The cleaning liquid composition comprises: an alkaline compound (A), a non-ionic surfactant (B) represented by the following structural formula (1), a reducing agent (C) and water (D). The structural formula (1) is as follow: R1-O-(E O)m(P O)n-H, wherein R1 is branched chain-containing alkyl with a carbon number of 6-20, alkenyl or acyl, or branched chain-containing alkylphenyl with a carbon number of 12-20, E O represents ethoxy (ethylene oxide); P O represents propoxy (propylene oxide), m represents an integer of 1-20, n represents an integer of 0-20, thearrangements of the (E O) and the (P O) can be block or random in the (E O)m(P O)n when the n represents an integer of 1-20.
Description
technical field [0001] The invention relates to a cleaning solution composition, in particular to provide a cleaning solution composition for glass substrates, which has strong cleaning power, good defoaming performance and is not easy to corrode the substrate to increase the surface roughness of the substrate. Background technique [0002] At present, as glass substrates for liquid crystal displays of TVs, personal computers, clocks and other items, such as soda-lime glass, borosilicate glass, silicon glass, and alkali-free glass, etc., glass mother plates can be obtained through fusion forming engineering, and the glass Motherboards are cut into glass substrates of any size for use. [0003] In addition, color filters commonly used in color liquid crystal displays, sensors, and color decomposition devices in recent years are made by forming a black matrix and red, green, and blue pixel images on a transparent glass substrate, and using disperse pigments The optically acti...
