Problems solved by technology

[0003] The existing method for testing the compatibility of water-based color paste in latex paint is: use a certain amount of color paste to mix evenly in latex paint and then test, mainly based on GB / T 21090-2007 "Colorable Latex Base Paint", Although this method is relatively simple, it is not accurate enough and cannot reflect the compatibility of color paste and latex paint during construction and storage. Sometimes it passes the standard test, but incompatibility still occurs in actual application. , which brings inconvenience to the process of production and application

Abstract

The present invention relates to the detection method of latex paint compatibility, particularly relates to the detection method of the compatibility of water-based color paste in latex paint, water-based color paste is added in latex paint and evenly stirred to make standard sample paint, and then random sampling 3 Standard sample paints with the same weight, and then the three standard sample paints are processed, card-made, detected and calculated to obtain the color difference value. When all the color difference values ​​meet the requirements, that is, when they are less than 0.5, it is judged as the above-mentioned The compatibility of the sample water-based color paste in latex paint is qualified. The detection method can accurately measure the compatibility of the water-based color paste in the latex paint, prevent the latex paint from floating and blooming, and save the use cost. The detection method is easy to operate, short in time and high in accuracy, and prevents the occurrence of missed detection in the detection method firstly used.

Description

technical field [0001] The invention relates to a detection method for the compatibility of latex paint, in particular to a detection method for the compatibility of water-based color paste in latex paint. Background technique [0002] In the use of latex paint, it is often necessary to add water-based color paste for color matching. The compatibility of water-based color paste from different manufacturers with latex paint of different formulas is very important. If the compatibility is not good, the color development of the paint will become worse. Unstable, the paint will appear floating color and flowering during construction, and the color of the paint will also change during storage. [0003] The existing method for testing the compatibility of water-based color paste in latex paint is: use a certain amount of color paste to mix evenly in latex paint and then test, mainly based on GB / T 21090-2007 "Colorable Latex Base Paint", Although this method is relatively simple, ...
