Abstract

The invention discloses a super-weather-proof water-based metallic paint, and belongs to the field of a water-based paint. The super-weather-proof water-based metallic paint comprises the following components in percentage by weight: 88-91% of finish-coat paint, 8-10% of pearl powder, 0-2% of pigment and 1% of a thickener. The invention further discloses a preparation method of the super-weather-proof water-based metallic paint. The super-weather-proof water-based metallic paint has favorable hiding power, excellent contamination resistance and self-cleaning function, excellent pain film property, high weather resistance, scrubbing resistance, ageing resistance, scratch resistance, rice color, rich metallic color, obvious quality and good gloss effect; the paint is applicable for inner and outer wall surfaces and metal surfaces, calcium silicate board surfaces and other decorative material surfaces, the application scope is wide. The preparation method is easy to implement, the three wastes are avoided during the production process, and so the preparation method is environmentally friendly and safe.

Description

technical field [0001] The invention relates to the field of water-based coatings, in particular to a super-weather-resistant water-based metal coating and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the rapid development of the national economy, people's awareness of environmental protection is increasing day by day, and their pursuit of health is also getting higher and higher. Environmental protection and energy saving have become the main issues facing the global coatings industry.
