Effect of different color slurry anti-sinking agent on the floating color and leveling of gray epoxy floor.

Gray epoxy floor paint by color slurry, curing agent, solvent, construction ground flatness and temperature and humidity and other factors, very easy to appear floating color, resulting in a certain construction interval color difference and flowing floating color, resulting in the overall appearance of the effect is not beautiful. In order to reduce the floating color of the floor, especially in the case of low temperature, many external factors, tag additive Chongqing Application Center in the early optimization of dispersants on the basis of the first stage, will start the color slurry system of anti-sinking agent optimization screening work. With common gas-phase silica (including hydrophobic and hydrophobic), bentonized soil (containing machine-modified), liquid polyamide, polyamide wax and other raw materials were designed black and white color slurry anti-sinking, and the effects of different color-based slurry anti-sinking agents on the floating color of gray epoxy floor were examinedIn the process of sample paint construction, the paper focuses on whether there is a construction color difference (simulated construction joint) with a gap of 20 minutes after the curing agent is used, and the flowing floating color (simulated foundation unevenness) produced by the reverse paint, and takes into account the flat condition of the paint film to explore the reasonable choice of color slurry anti-sinking agent.

show that the application of different anti-sinking agents to epoxy flooring slurry has obvious effect on floating color:
hydrophobic modified gas silicon is more suitable for light gray epoxy flooring slurry than hydromassage silicon;
Hydro-hydro-gas silicon with Tech-9028 and bento-earth can improve the color difference of construction interval;
hydro-hydro-gas silicon with Tech-9607 class has no significant improvement, and the leveling effect is large

In the light gray paint storage process and storage after the re-construction, the experiment shows:
light gray slurry anti-sinking: hydrophobic gas silicon and benthic soil YH-908H , substation anti-sinking: Tech-9020 plus hydromassage silicon or bento-earth, storage stability is better, there are no floating color anomalies in the tank, not easy to appear construction interval color difference.
Fact, in epoxy system, pigments involve dispersion and stability, not only by dispersants and anti-sinking agent types and dosages, but also by solvent polarity, curing agent residues of small molecular amines and so on. In the end, the cause of floating color is often the comprehensive result of more factors, which need to be analyzed in detail to determine the solution of the factors. Subsequent laboratories will gradually conduct float assessment experiments with more factors based on customer requirements.
