Problems solved by technology

If the seborrheic alopecia is still in the initial stage, it can be treated by self-regulation and combined with medication. The popular minoxidil and finasteride drugs on the market are very effective in the treatment of hair loss. However, for patients with severe hair loss, they can only choose hair transplant surgery for treatment. In fact, the cure rate is not high, which seriously affects the self-confidence and image of patients.

Abstract

The invention relates to a preparation method and application of nanometer titanium dioxide suspension liquid. The preparation method comprises the following steps: using an ethanol solution with themass concentration of 1% to 50% prepared from 0.425 to 4.25 g of tetrabutyl titanate as a raw material, or using a water solution with the mass concentration of 1% to 50% prepared from 0.1125 to 1.125g of titanium tetrachloride as a raw material, adjusting the pH to obtain flocculent titanium hydroxide through treatment, then carrying out dispersion treatment and closed heating to obtain the titanium dioxide suspension liquid, continuously carrying out dispersion treatment, and finally obtaining the uniformly dispersed and stable nanometer titanium dioxide suspension liquid without sedimentation or impurity organic matters. The nanometer titanium dioxide suspension liquid has good application effects in the aspects of whelk removal treatment, wound healing treatment, hair loss treatment and dandruff removal.

Description

Technical field: [0001] The invention relates to a preparation method and application of nano titanium dioxide suspension. Background technique: [0002] Nano-titanium dioxide is rutile-type and anatase-type white loose powder. It has strong ultraviolet shielding effect, good dispersion and weather resistance, and has anti-line, antibacterial, self-cleaning, and anti-aging properties. It can be used in cosmetics, functional fibers, plastics, and inks. , coatings, paints, fine ceramics and other fields. As a representative material of photocatalyst, titanium dioxide is currently the most ideal material for controlling indoor environmental pollution in the world. With the development of society and the advancement of science and technology, people gradually recognize, understand and apply titanium dioxide to different fields and achieve good results. However, due to the problems of easy sedimentation, unevenness of the product as a whole, and organic impurities in the existi...
