Problems solved by technology

[0004] In the prior art, there are also many patents or documents disclosing some water-based wood coatings and their production methods, but the coating effects in these patents mostly only meet some basic physical performance indicators of environmental protection performance and paint film, and the construction method is generally only Ordinary brushing or spraying, if it is used for roller coating, the defoaming property is poor, and there is no special roller coating method for container floor paint.
Other special additional functions are not very ideal, and the cost is high
In addition, most of these coatings do not have the characteristics of anti-high temperature back tack, anti-cracking under hot and cold conditions, and additional composite functions such as anti-mold and high wear resistance. Cracking, high temperature back tackiness and other properties

Abstract

The invention discloses waterborne wood floor paint for roller painting of containers. The waterborne wood floor paint comprises a first component, a second component and water in a mass ratio of 100:5-10:10-20. The first component is prepared from a composite modified self-crosslinking acrylic polymer, a composite modified wear-proof polymer, an anti-foaming agent, a dispersing agent, a waterborne flatting agent, a thickening agent, a leveling agent, smoothening and anti-adhesion additives, an anti-mildew bactericide and the balance water. The second component is prepared from a composite modified cross-linking agent and water. The waterborne wood floor paint for roller painting of the containers is great in effect, environmental friendly, especially suitable for roller painting, excellent in anti-foaming performance and abrasion resistance, high in hardness, excellent in anti-cracking performance under cold and hot conditions, anti-adhesion performance at a high temperature and water resistance, quick in drying, moderate in cost, easy in construction and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of water-based wood coatings, in particular to a water-based wood floor paint for container roller coating and a preparation method thereof. Background technique [0002] As a decorative material, wood floor paint has higher and higher decorative requirements and environmental performance. As a wood floor decoration material for containers, the traditional two-component solvent-based PU wood floor paint has different product formulas and processes. It is very mature, and its product performance can also meet higher demands. It is mainly manifested in the application of roller coating, which is easy to defoam, good adhesion and fullness, high hardness can reach between H-2H, water resistance, high temperature resistance and back adhesion It has good alcohol and alcohol resistance and is not easy to lose luster. However, because it contains a large amount of volatile organic compounds (VOC), it will cause cert...
