1. A preparation method of an environment-friendly wall paint for a building, comprising the following steps:
(1) preparing various raw materials by weight for later use;
wherein 20-30 kg of glue powder, 8-12 kg of silica gel, 10-12 kg of nano-montmorillonite composite powder, 10-12 kg of diatomite dispersion, 2-6 kg of nano-calcium silicate, 4-6 kg of nano-titanium dioxide, 2-5 kg of glass fiber powder, 10-20 kg of red clay, 10-20 kg of lime, 30-40 kg of water, 2-5 kg of lignin, 4-8 kg of acrylamide, 2-5 kg of alfalfa meal, 2-5 kg of tobacco straw fiber powder, 2-8 kg of Ligusticum chuanxiong Hort extracting solution, 2-8 kg of Agastache rugosa extracting solution, 2-8 kg of mint extracting solution, and 5-8 kg of natural plant essential oil;
(2) mixing and uniformly stirring the glue powder, the nano-montmorillonite composite powder, the nano-calcium silicate, the nano-titanium dioxide, the glass fiber powder, the red clay, the lime, the alfalfa meal and the tobacco straw fiber powder to obtain mixed powder;
(3) adding the mixed powder of step (2) into the water, stirring in a stirring tank at rotation speed of 500-700 rpm, at a temperature of 70-80° C. and stirring time of 30-40 min, and cooling after stirring to maintain a temperature at 40-45° C. for 1-2 hours to obtain colloidal emulsion;
(4) adding the silica gel, the diatomite dispersion, the lignin and the acrylamide into the colloidal emulsion of step (3), and keeping stirring at rotation speed of 150-200 rpm; and
(5) continuing to add the Ligusticum chuanxiong Hort extracting solution, the Agastache rugosa extracting solution, the mint extracting solution and the natural plant essential oil, increasing the rotation speed of the stirring tank to 600-800 rpm and the stirring time to 30-40 min, and waiting until the environment-friendly wall paint is uniformly stirred without bubbles.
