preparation example Construction
[0063] The preparation method of described building paint, comprises the steps:
[0064] Step S1, adding the dispersant and NXZ defoamer into water, stirring at a speed of 400-500r / min for 7-10min to obtain a mixture;
[0065] Step S2, add the formula amount of common filler and functional filler, disperse at a speed of 1000-2000r / min for 15-60min, then carry out high-speed dispersion and grinding for 30-50min until the fineness is ≤40um, stir at a low speed of 300-400r / min for 12min, get slurry;
[0066] Step S3, at a rotational speed of 400-600r / min, sequentially add the formulated amount of protective colloid solution, antifungal agent, antibacterial agent, polymer emulsion and rheological additive, and stir for 55-65min to obtain an energy-saving and environment-friendly architectural coating.

Abstract
The invention discloses an energy-saving and environment-friendly architectural coating, which is prepared by the following main principles in parts by weight: 35-60 parts of polymer emulsion, 15-25 parts of common filler, 10-15 parts of functional filler, 3-10 parts of water, and protective colloid solution 2‑10, 0.05‑0.2 part of antifungal agent, 0.05‑0.2 part of antibacterial agent, 0.2‑0.6 part of dispersant, 0.2‑1 of rheological additive, 0.2‑0.6 of NXZ defoamer; the invention also discloses the architectural coating The preparation method comprises the following steps: step S1, adding dispersant and NXZ defoamer to water, stirring at a speed of 400-500r / min for 7-10min to obtain the mixture; step S2, adding a formula amount of common filler and functional Filling to obtain a slurry; step S3, adding a formulated amount of protective colloid solution, antifungal agent, antibacterial agent, polymer emulsion and rheological additive, and stirring evenly. The present invention uses polymer emulsion as the main body of the coating, supplemented with fillers, antifungal agents, antibacterial agents and auxiliary agents. The raw materials are green and environmentally friendly, low in VOC, and will not cause environmental pollution. The prepared architectural coatings are safe, environmentally friendly, stain-resistant, and durable Mildew resistance, heat insulation and other advantages.
Description
technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to an energy-saving and environment-friendly architectural coating and a preparation method thereof. Background technique [0002] Architectural coatings include water-based architectural coatings and solvent-based architectural coatings. Solvent-based architectural coatings are restricted in architectural coatings because they release toxic solvents during the curing process and do not meet environmental protection requirements. It has strong aging resistance and is still used in the exterior wall decoration of high-rise buildings. [0003] In recent years, with the accelerated deterioration of the atmospheric environment and the increasing awareness of environmental protection, the call for restrictions on volatile organic compounds (VOC) is also increasing, and the country is also paying more and more attention to the environmental protection requiremen...
