Embodiment 1

[0044]Add oleic acid to a glass reactor. Nano-rutile titanium dioxide was mixed with an equal mass of monoalkoxy unsaturated fatty acid titanate coupling agent (LD-105) and stirred to form a homogeneous mixture. The mixture is added into the oleic acid while stirring, so that the final content of the nano-titanium dioxide in the composite is about 2% by weight. During the reaction, the rotational speed was controlled at about 200 rev / min. The temperature of the reactor was controlled at 80 degrees, and after 2 hours, the reactor was shut down to cool down to room temperature, the compound was released, and left to stand for 24 hours. Supernatant liquid crosses 500 mesh screens to remove a small amount of impurity that is brought into in the raw material, collects filtrate and obtains the composite of nano-titanium dioxide and oleic acid that 4kg nano-titanium dioxide content is about 2% by weight.

Embodiment 2

[0049] Stearic acid was added to a glass reactor. Nano-rutile titanium dioxide was mixed with an equal mass of monoalkoxy unsaturated fatty acid titanate coupling agent (LD-105) and stirred to form a homogeneous mixture. The mixture is added into the stearic acid while stirring, so that the final content of the nano-titanium dioxide in the composite is about 1% by weight. During the reaction, the rotational speed was controlled at about 200 rev / min. Control the temperature of the reactor at 80°C, shut down the reactor after 2 hours and cool it down to room temperature, release the complex, and let it stand for 24 hours. Supernatant liquid crosses 500 mesh sieves to remove a small amount of impurity that is brought into in the raw material, collects filtrate and obtains the compound of nano-titanium dioxide and stearic acid that 5kg nano-titanium dioxide content is about 1% by weight.

Embodiment 3

[0054] Add lauric acid to a glass reactor. Nano-rutile titanium dioxide was mixed with an equal mass of monoalkoxy unsaturated fatty acid titanate coupling agent (LD-105) and stirred to form a homogeneous mixture. The mixture is added into the lauric acid while stirring, so that the final content of the nano-titanium dioxide in the composite is about 4% by weight. During the reaction, the rotational speed was controlled at about 200 rev / min. Control the temperature of the reactor at 90°C, shut down the reactor after 2 hours and cool it down to room temperature, release the complex, and let it stand for 24 hours. Supernatant liquid crosses 500 mesh sieves to remove a small amount of impurity that is brought into in the raw material, collects filtrate and obtains the compound of nano-titanium dioxide and lauric acid that 3kg nano-titanium dioxide content is about 4% by weight.

Abstract

The invention provides a modified aluminum pigment comprising, based on the total weight of the modified aluminum pigment, 60-70 wt% of flake aluminum powder, 3-5 wt% of a compound formed by nano-titanium dioxide and fatty acid, and 25-35 wt% of an organic solvent, wherein the weight ratio of nano-titanium dioxide to fatty acid is (0.5-5):100. The invention also provides a corresponding preparation method of the modified aluminum pigment and a coating containing the modified aluminum pigment. Compared with traditional aluminum pigments, the modified aluminum pigment has better metal sensationand better angle-dependent optical effect.

Description

technical field [0001] The invention belongs to the technical field of fine inorganic chemicals, and in particular relates to a modified aluminum pigment, a preparation method thereof and a coating containing the same. Background technique [0002] Aluminum pigment is an important metal effect pigment, which is mainly used in coatings, inks, printing and dyeing, plastic products, papermaking, rubber products and ceramics. With the rapid development of downstream industries, the demand for pigments continues to expand. China's pigment industry The development prospect is very broad. Aluminum pigments are produced with pure aluminum metal, which has many characteristics of aluminum metal itself; the aluminum micropowder in aluminum pigments is actually a micron-scale flake (disc or near-circle) with pigment properties coated with a fatty acid film on the surface sheet), this shape makes it have unique characteristics, because of its superior corrosion resistance and decorativ...
