Abstract

The invention discloses a preparation method of a nano-coating. The nano-coating is prepared from modified polyvinyl alcohol, nano-zinc oxide, aluminum oxide, talcum powder, heavy calcium carbonate, aluminum sulfate, silicone-acrylic emulsion, a whitening agent, nanosized titania, nickel oxide, polyacrylamide, sodium bentonite, OK powder, potassium alum, water, a dispersing agent, a defoaming agent, ethylene glycol, a PH regulator, porous powder quartz, ammonium polyphosphate, elastic acrylic emulsion, zinc borate, a coalescing agent, a wetting agent, bactericide and a thickening agent. The product has the advantages of good antibacterial effect, 100 percent of six-hour sterilizing rate, good caviation oxygen effect, 56 percent of VOC purification rate and about 100 per cubic millimeter ofnegative oxygen ions; the product has the functions of ecological environmental protection, bacteria resistance, health care, air purification and the like, belongs to a waterborne inorganic materialand has no toxicity, low cost and high performance; meanwhile, the production of the product can be met without changing existing production technology and equipment.

Description

technical field [0001] The invention relates to a nano-type coating, in particular to a preparation method of the nano-type coating. Background technique [0002] Due to the small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect of nanoparticles, they exhibit characteristics that conventional materials do not have in terms of magnetism, light, electricity, and sensitivity. Therefore, nanoparticles have broad application prospects in magnetic materials, electronic materials, optical materials, sintering of high-density materials, catalysis, sensing, and ceramic toughening. Generally speaking, nano-coatings must meet two conditions: first, at least one phase in the coating has a particle size in the range of 1-100nm; secondly, the presence of nano-phases can significantly improve the performance of the coating or have new features. function. However, the antibacterial effect of existing nano coatings is not good, the bactericidal rate...
