Abstract

The invention belongs to the technical field of container repair paint, and particularly relates to container waterborne acrylic acid external repair paint and a preparation method thereof. The container waterborne acrylic acid external repair paint is prepared from the following components in parts by weight: 5-10 parts of water, 0.1-0.3 part of a bactericide, 0.03-0.06 part of an anti-sedimentation agent, 0.3-0.5 part of a pH regulator, 0.8-1.2 parts of a defoamer, 0.3-0.5 part of a dispersant, 1 part of titanium dioxide, 20-40 parts of a filler, 45-50 parts of acrylic resin, 3.6-4.5 parts of a coalescing agent, 0.3-0.5 part of a wetting leveling agent, 1.8-2.2 parts of color paste and 0.2-0.4 part of a thickener. The VOCs content of the container waterborne acrylic acid external repairpaint is less than 85 g/L, environment pollution is avoided, strong irritant smell is also avoided, and the container waterborne acrylic acid external repair paint has the characteristics of environmental protection and safety. Meanwhile, the prepared waterborne repair paint is short in surface drying and hard drying time, high in drying speed, good in paint film closure and good in water-resistant performance.

Description

technical field [0001] The invention belongs to the technical field of container repair paint, and in particular relates to a container water-based acrylic surface repair paint and a preparation method thereof. Background technique [0002] In 2017, the China Container Association enforced the implementation of water-based container coatings, especially box body paint and chassis paint. However, solvent-based paints are still allowed for primary zinc-rich paint, box marking paint, and refinish paint. [0003] As a kind of container coating, container refinish paint is characterized by open-air construction. If solvent-based refinish paint is used, a large amount of organic solvent emissions will be generated. High VOCs emissions will not only pollute the environment, but also cause harm to the health of construction workers. influences. As local governments restrict the use of solvent-based coatings more and more strictly, and the implementation of environmental protection...
