Problems solved by technology

However, due to some inherent properties of water-based silver powder immersion paint, the storage stability of silver powder immersion paint is not good, and the paint liquid is easy to delaminate, which makes the arrangement of aluminum powder on the surface of the dipped workpiece rough, and the appearance decoration effect and adhesion cannot be achieved. The customer's use needs, and the paint film has a long drying time and poor weather resistance, so it largely limits the application of water-based silver powder immersion paint in the market

Abstract

The invention provides a water-based quick drying anticorrosive storage-stable silver powder dipping paint and a preparation method thereof. The silver powder dipping paint is prepared from the following components: 40 to 60 parts of hydroxyl acrylic emulsion, 6 to 8 parts of aluminum powder pigment, 0.5 to 1 part of a directional agent, 1 to 2 parts of a thickening agent, 2 to 4 parts of a flash rust resisting agent, 5 to 10 parts of a cosolvent, 2 to 5.5 parts of a functional additive and 15 to 25 parts of deionized water, wherein the aluminum powder pigment is micron-level aluminum powder of which the surface is coated with a silica film and the average particle diameter of the micron-level aluminum powder is 5 to 12mu m and the average thickness of the silica film is 2 to 5nm. The water-based quick drying anticorrosive storage-stable silver powder dipping paint disclosed by the invention has the advantages that the drying time is short; a formed paint film is smooth and flat and has metal texture; in addition, the water-based quick drying anticorrosive storage-stable silver powder dipping paint has high adhesion to the surface of an object, better salt spray resistance and artificial aging resistance and better storage stability; the phenomena of precipitation, layering and floating after the water-based quick drying anticorrosive storage-stable silver powder dipping paint is stood for a long time can be avoided, therefore, a good application prospect can be achieved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to the field of water-based paints, in particular to a water-based quick-drying anti-corrosion and storage-stable silver powder immersion paint and a preparation method thereof. Background technique [0002] With the continuous enhancement of people's awareness of health, safety and environmental protection and the continuous strengthening of environmental protection regulations, the trend of water-based industrial coatings is becoming more and more obvious. Promote the development of coatings in the direction of high-solid coatings, water-based coatings and other environmentally friendly coatings. Among them, water-based coatings that use water as a solvent have the advantages of saving resources and low VOC emissions, so they have developed rapidly. [0003] As a coating material, water-based silver powder dipping paint is in line with the policy orientation of energy conservation, environ...
