Abstract

This invention is that a kind of multi-functional green nanometer two of environmental protection is oxidized Titanium coating and method of preparing, this coating can not merely be solved now. There is coating that is able to bear staining difference, is able to bear waiting difference, not the skills, such as environmental protection, etc. Skill question, it is clean to give the coating at the same time, disinfect and disinfect, Purify new functions, such as air, etc., it is the green environmental protection of more than one kind of kinetic energy Coating. Coating this by titanium white powder, exceed detailed silicic acid aluminium, nanometer Oxidize the titanium and disperse the liquid two times, the calcium carbonate of light quality, the calcium carbonate of heavy quality, Silicon lime powder, lithopone, talc powder, dispersant is moist. It is the dispersant, thickener, disappear and steep and pharmaceutical, become membrane auxiliary, flow flat pharmaceuticla, water, the cream base material, etc. make up, it is simple to prepare the craft. The cost performance is high, have very good economic benefits and social result Benefit.

Description

technical field [0001] The patent of the invention relates to the field of architectural coatings, in particular to a multifunctional green and environment-friendly nano-titanium dioxide coating and a preparation method thereof. Background technique [0002] At present, my country's architectural coatings generally have low-grade products, short service life, easy to stain, and poor weather resistance. Whether the technical problems such as poor weather resistance and easy staining can be solved is the key to whether the exterior wall coating can be widely used. [0003] With the improvement of people's living standards, higher requirements are put forward for architectural coatings. It is required that architectural coatings not only have decorative functions, but also have new functions such as sterilization, air purification, and radiation protection. [0004] Nano-titanium dioxide has stable chemical properties, oxidation resistance, safety and non-toxicity, and long s...
