Problems solved by technology

At present, there are deficiencies in the industrialization technology of the water-based aluminum powder immersion process, and the industrialization cannot be carried out
Moreover, the obtained water-based aluminum powder has insufficient soaking and wetting and uneven dispersion, and the water-based aluminum-silver paste made has poor stability and cannot be directly added to the water-based varnish system, and the resulting product quality has problems.

Embodiment 1

[0025] (1) Production preparation: check whether the production equipment is operating normally; ensure that the production equipment is clean; accurately measure and record the proportion and dosage of various raw materials in the production formula according to the formula sheet, and select measuring instruments with appropriate measuring ranges.

[0026] (2) Soaking and dispersing of water-based aluminum powder: first add the co-solvent ethylene glycol monobutyl ether, anti-sedimentation agent AQH-800 and alignment aid 3050 in the production formula into the mixing tank, move to the high-speed mixer, and press The high-speed mixer is operated according to the operation rules. The stirring speed is controlled at 1500r / min. After the dispersion is uniform, the stirring speed is reduced to 300r / min. After 30 minutes, use AMP-95 to adjust the pH value of the aluminum-silver paste to pH=7.0. After stirring evenly, let it stand for 1 hour, so that the water-based aluminum powder W...

Embodiment 2

[0030] (1) Production preparation: check whether the production equipment is operating normally; ensure that the production equipment is clean; accurately measure and record the proportion and dosage of various raw materials in the production formula according to the formula sheet, and select measuring instruments with appropriate measuring ranges.

[0031] (2) Soaking and dispersing of water-based aluminum powder: First, add the co-solvent propylene glycol, anti-sedimentation agent BYK-420 and alignment aid BYK-8421 into the mixing tank, move to the high-speed mixer, and operate according to the high-speed mixer According to the standard operation, the stirring speed is controlled at 2500r / min. After the dispersion is uniform, the stirring speed is reduced to 1000r / min. Under the stirring condition, add Zhongsu nano water-based aluminum powder 9918, disperse for 30min, and adjust the pH value of the aluminum silver paste to pH=8.0, after stirring evenly, let it stand for 2 hou...

Embodiment 3

[0035] (1) Production preparation: check whether the production equipment is operating normally; ensure that the production equipment is clean; accurately measure and record the proportion and dosage of various raw materials in the production formula according to the formula sheet, and select measuring instruments with appropriate measuring ranges.

[0036] (2) Soaking and dispersing of water-based aluminum powder: first add the co-solvent diethylene glycol butyl ether, anti-sedimentation agent BYK-420 and alignment aid LH-H018 in the production formula into the mixing tank, and move it to the high-speed mixer. And operate according to the operating procedures of the high-speed mixer, the stirring speed is controlled at 2000r / min, after the dispersion is uniform, the stirring speed is reduced to 800r / min, and Jinyangyang aluminum powder SX515 is added under the stirring condition, and the pH value of the aluminum silver paste is adjusted to pH=7.5, after stirring evenly, let it...

Abstract

The invention discloses a waterborne aluminum paste for decorative waterborne metallic shining coating. The waterborne aluminum paste comprises the following components by mass: 25-35% of waterborne aluminum powder, 25-45% of a cosolvent, 8-18% of an anti-settling agent, 12-25% of a directional arrangement assistant, and 1-5% of a pH regulator. The invention also discloses a preparation method of the waterborne aluminum paste. The waterborne aluminum paste has stable performance during 1-2d short-term storage, can be directly added into a waterborne varnish system to reduce the product quality problem caused by poor dispersion of waterborne aluminum powder and improve the primary production qualified rate, and the operation is simple, thus being suitable for industrial mass production.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a water-based aluminum silver paste for decorative water-based metallic glitter coatings. The invention also relates to the soaking production process of the water-based aluminum-silver paste. Background technique [0002] In recent years, with the further development of the paint industry and people's increasing awareness of environmental protection, the regulations on the discharge of toxic solvents into the atmosphere have become increasingly strict, and the replacement of organic solvents with water has become an inevitable trend in the development of the paint industry. Water-based metallic glitter coatings are more and more popular in the market because they use water as a solvent, avoiding safety issues such as flammability and explosion caused by organic solvents such as benzene, as well as environmental protection and health issues. In addition to the funct...
