Embodiment 1

[0042] 1. Preparation of water-based iron oxide color paste

[0043] The formula of water-based iron oxide color paste is shown in Table 1. The preparation process is as follows: ①Put deionized water and different kinds of co-solvents into the stirring tank, and then add BYK-190, FX600, TEGO-500, TEGO-901w, after being dispersed evenly, continue to add RD and iron oxide powder, and stir for 10-15min at a linear speed of 8-9m / s; ②Pour the evenly stirred iron oxide color paste into the sand mill, and grind for 45min-1h , when the fineness is less than 5μm, the iron oxide color paste can be obtained.

[0044] 2. Preparation of water-based one-component iron oxide paint

[0045] Add the resin 2606 into the stirring tank, add 2-amino-2-methyl-1-propanol while stirring, and after neutralizing for 5 minutes, slowly add the ground iron oxide color paste, TEGO-830, TEGO-240, FX1070 , Stir for 30 minutes after adding all the materials, filter and discharge the material, and then get t...

Embodiment 2

[0058] Table 3 is the feeding formula for preparing the water-based iron oxide paint by changing the type of dispersant in Example 2 while keeping other materials unchanged, and the formula numbers are 5, 6, 7 and 8 in sequence. According to the technological process of embodiment 1 preparing water-based single-component iron oxide colored paint, the numbering shown in table 3 is 4 kinds of iron oxide colored paints of 5~8, and the technological process of preparing iron oxide colored paint film according to embodiment 1 prepares paint film .

[0059] The properties of the waterborne one-component iron oxide paint prepared by formula 5, formula 6, formula 7 and formula 8 are shown in table 4. It can be seen from the table that when the dispersant combination of (BYK-190+FX600) or (BYK-194N+OROTAN+BYK-151) is used in the formula, the water-based one-component iron oxide paint has excellent storage stability, Freeze-thaw stability, hiding power, adhesion, flexibility, water res...

Embodiment 3

[0068] Table 5 is the feeding formula for preparing the water-based iron oxide paint by changing the proportion of dispersant in Example 3 while keeping other materials unchanged, and the formula numbers are 9, 10, 11 and 12 in sequence. The technological process of preparing water-based single-component iron oxide colored paint according to embodiment 1 is numbered 4 kinds of iron oxide colored paints shown in table 5 as 9~12, prepares paint film according to the technological process of embodiment 1 preparing iron oxide colored paint film .

[0069] The properties of the waterborne one-component iron oxide paint prepared by formula 9, formula 10, formula 11 and formula 12 are shown in table 6. It can be seen from the table that when the ratio of dispersant BYK-190 and FX600 is 0.5:4.5, the water-based iron oxide paint has excellent hiding power, adhesion, flexibility, chemical resistance and weather resistance, but its storage stability, Freeze-thaw stability and water resi...

Abstract

The invention discloses water-based one-component automobile paint containing iron oxide pigment and a preparation method of the water-based one-component automobile paint. The water-based one-component automobile paint containing the iron oxide pigment is prepared from resin, an amine neutralizer, iron oxide color paste and an assistant, wherein the iron oxide color paste is prepared from deionized water, a cosolvent, an assistant and iron oxide powder. The preparation method comprises the following steps of firstly, feeding materials according to a formula of the iron oxide color paste, and then dispersing at high speed for 10 to 15 minutes; secondly, entering a sand mill and grinding until the fineness is smaller than 5 microns, thus obtaining the iron oxide color paste; thirdly, sequentially feeding the materials according to the formula of the iron oxide colored paint, and uniformly stirring to obtain water-based iron oxide colored paint. The water-based one-component iron oxide colored paint provided by the invention has the advantages of excellent storage stability, excellent freeze-thaw stability, excellent covering power, excellent water resistance, chalking resistance and weather resistance, excellent constructability and sagging resistance, and great drying speed.

Description

technical field [0001] The invention relates to the technical field of automobile coatings, in particular to a water-based one-component iron oxide color paint with excellent comprehensive performance and a preparation method thereof. Background technique [0002] At present, my country's automotive coatings are still mainly solvent-based, and a large number of volatile organic compounds (VOCs) have caused serious pollution to the ecological environment during the coating process, and have also brought great harm to human health. With the improvement of people's awareness of environmental protection, governments of various countries have introduced a large number of relevant regulations to limit the emission of VOCs. In order to keep up with the development of the times, automotive coatings are changing to be environmentally friendly. Environmentally friendly coatings include water-based coatings, powder coatings, UV-curable coatings and high-solid coatings, and water-based ...
