Title:
WATERBORNE DIPPING COATING FOR MEASURING TAPE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/001004
Kind Code:
A1
Abstract:
A waterborne dipping coating for a measuring tape, relating to the field of waterborne coatings, and comprising the following components in parts by weight: 45-55 parts of a waterborne hydroxy acrylic acid secondary dispersion, 1-2 parts of a waterborne epoxy resin, 6-10 parts of a partially methylated amino resin, 0.1-0.5 parts of a pH regulator, 2-6 parts of a coalescing agent, 0.5-1 parts of a dispersing agent, 0.1-0.3 parts of a wetting agent, 0.1-0.3 parts of a defoaming agent, 1-2 parts of a waterborne blocked isocyanate curing agent, 10-20 parts of water, 20-25 parts of titanium dioxide, 0.5-1 parts of an anti-settling and anti-sagging auxiliary agent, and 0.2-0.5 parts of a thickening agent. The pH regulator, the dispersing agent, the wetting agent, the defoaming agent, the titanium dioxide, and the anti-settling and anti-sagging auxiliary agent are stirred to obtain early-stage water slurry, and then the waterborne hydroxyl acrylic acid secondary dispersion, the partially methylated amino resin, the waterborne epoxy resin, the waterborne blocked isocyanate curing agent, the early-stage water slurry, the coalescing agent, and the thickening agent are uniformly stirred to obtain the waterborne dipping coating for a measuring tape. The waterborne dipping coating for a measuring tape prepared in the present invention has a low VOC content, and has properties such as high adhesion, high hardness, and excellent salt spray resistance.
