Embodiment Construction

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0035] In view of the relatively harsh storage conditions and poor storage stability of water-based paints, the embodiment of the present invention proposes a method for measuring and evaluating the storage stability of water-based paints. figure 1 , the determination and evaluation method comprises the following steps:

[0036] S1: sample collection, according to the sampling of paint products specified in GB3186-82, take out the test sample, put it into a container and close the container cover tightly, preferably, the sample liquid surface is 15mm away from the top of the container cover in the container. It is advisable to weigh, and the weighing result is preferably accurate to 0.2g;

[0037] S2: Confirm the initial state of the sample, confirm that the s...

Abstract

The invention relates to the technical field of paint detection and discloses a method for testing and evaluating storage stability of water paint. According to the method, a storage environment condition of a sample of the water paint in the storage stability testing process is determined on the basis of a traditional solvent-type paint storage stability detection method GB 6753.3-86: the sample is stored for 30 days at the temperature of 20 DEG C or stored for 10 days at the temperature of 30 DEG C or stored for 6 months in natural environment; evaluation conditions of checking of skinning, corrosion and a stale flavor, checking of the sedimentation degree, checking of paint film particles, glue blocks and brush marks, checking of a PH (potential of hydrogen) value, checking of a viscosity value and a paint film hue value and the like are determined. According to the method for testing and evaluating the storage stability of the water paint, whether the storage stability of different kinds of water paint or the water paint provided by different suppliers is good can be judged conveniently, and a basis is provided for determination of the storage cycle of the water paint.

Description

technical field [0001] The invention relates to the technical field of paint detection, in particular to a method for measuring and evaluating the storage stability of water-based paint. Background technique [0002] Due to the characteristics of water-based paint, the resin in the paint is unevenly distributed, which will have a great impact on the appearance after painting. It is necessary to add a suitable surfactant to stabilize it. Therefore, compared with traditional solvent-based paints, water-based paints have poorer storage stability, especially for special-color water-based paints with low output at the production site. important. However, there are no relevant standards and methods to measure and evaluate the storage stability of water-based paints. Contents of the invention [0003] The purpose of the present invention is to provide a method for measuring and evaluating the storage stability of water-based paints, to detect the storage stability of water-base...
