Problems solved by technology

[0003] When the powder is applied, due to its original nature of large specific surface energy, there are many contact points between particles, which makes it easy to agglomerate. As a result, the dispersibility in the solvent becomes poor, and it is easy to cause sedimentation and poor suspension. Instability problems such as floating color or powder settling in solid products, resulting in poor uniformity and hiding power when the product is used / smeared

Abstract

The invention discloses water-in-oil titanium dioxide dispersion slurry. The water-in-oil titanium dioxide dispersion slurry is mainly prepared from, by mass, (a) 5-40% of titanium dioxide, (b) 5-30% of an oil phase composed of one or more oil-based components, (c) 0.5-5% of a mixed emulsifying agent composed of one or more emulsifiers, (d) 0.1-5% of a reverse emulsifier mixture composed of one or more reverse emulsifiers and (e) the balance water, wherein an HLB (hydrophile lipophile balance) value of the mixed emulsifying agent is 3-6. The water-in-oil titanium dioxide dispersion slurry has advantages of high powder content, high covering power, high stability and convenience in use.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a water-in-oil type titanium dioxide dispersion slurry. Background technique [0002] The slurry added to the product is made of various powders. According to the function of the powder, the selected powder is set according to its particle size range and chemical composition. For example, when the powder is titanium dioxide, a white inorganic pigment with a particle size of a few tenths of a micron to several microns plays the role of whitening, coloring, and sun protection. Titanium dioxide has three crystal forms in nature, anatase type (referred to as type A), rutile type (referred to as type R) and brookite type. Among them, the crystal structure of rutile is dense, relatively stable, low in optical activity, high in hiding power and decolorizing power, so it has better application performance and is widely used in coatings, inks, cosmetics and other fields, espe...
