Example Embodiment
[0023] Example 1
[0024] This example takes the preparation of 100kg of water-based paint as an example, and the preparation method is as follows.
[0025] The ingredients are weighed according to the specified ratio, and the dosage (kg) of each raw material is as follows:
[0026]
[0027] Natural colored sand is 10-80 mesh; emulsion is styrene-acrylic emulsion; cellulose ether is hydroxypropyl methyl cellulose ether (HPMC), molecular weight is 10,000-50,000; active adsorbent is activated clay, mesh It is 180-600 mesh; the particle size of heavy calcium carbonate is 1 μm; the film-forming aid is alcohol ester 12; the fungicide is HY-6060 of Maier Chemical.
[0028] The above-mentioned raw materials are weighed and batched according to the proportion, and added and stirred according to the conventional coating process to obtain the water-based coating.
[0029] When using, it can be used according to the conventional texture coating construction process.
[0030] For t...
