Abstract

The invention relates to the field of high-grade water-based paints, especially to a high-grade water-based paint using titanium dioxide as a filling material. The paint comprises the titanium dioxide filling material which is a mixture of titanium dioxide and sweet rice flour, wherein the titanium dioxide filling material comprises 1 to 50% by mass of titanium dioxide, with the balance being the sweet rice flour. With such a technical scheme, the sweet rice flour, calcium carbonate and quicklime are mixed to generate an organic / inorganic composite material which has a compact structure, high mechanical strength, good toughness and a good sealing effect on a substrate; and thus, the obtained paint has excellent adhesion, weatherability and aging resistance, does not contain harmful components, is safe and environment friendly and is easy to manufacture.

Description

technical field [0001] The invention relates to the field of high-grade water-based paints, in particular to high-grade water-based paints containing titanium dioxide as a filler. Background technique [0002] With the development of science and technology and social productivity, human beings pay more and more attention to the living environment. In particular, the state strictly controls the "triphenyl" solvent-based coatings. Coating manufacturers have done a lot of improvement work to adapt to the new situation in terms of product variety, quality, and environmental protection, and have made great progress. and environmentally harmful raw materials are imperative. The performance of titanium dioxide directly affects the application performance of water-based coatings. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting power, low dosage, and many varieties. It can protect the stability of the medium, and can enhance the mechanical st...
