Embodiment 1

[0037] This embodiment consists of the following raw materials (feeding according to the following weight ratios):

[0038]

[0039] The above materials are used to prepare the self-repairing water-based wood topcoat through the conventional mixing process of the water-based paint.

[0040] The obtained topcoat has the advantages of high hardness, good elasticity, self-repairing micro-cracks, high gloss, good weather resistance, etc., and is simple to operate, easy to construct, environmentally friendly and efficient, and is a new high-performance environmentally friendly wood coating material.

Embodiment 2

[0042] The present embodiment is made up of following raw material (according to following weight ratio):

[0043]

[0044] The self-repairing water-based wood paint is prepared by using the above materials through the conventional mixing process of the water-based paint.

[0045] The resulting topcoat has the advantages of high hardness, good elasticity, self-repairing of small scratches, high gloss, good weather resistance, etc., and is simple to operate, easy to construct, environmentally friendly and efficient, and is a high-performance new material for environmentally friendly wood coating.

Embodiment 3

[0047] The present embodiment is made up of following raw material (according to following weight ratio):

[0048]

[0049] The above materials are used to prepare the self-repairing water-based wood topcoat through the conventional mixing process of the water-based paint.

[0050] The resulting topcoat has the advantages of high hardness, good elasticity, self-repairing of small scratches, high gloss, good weather resistance, etc., and is simple to operate, easy to construct, environmentally friendly and efficient, and is a high-performance new material for environmentally friendly wood coating.

Abstract

The invention discloses a self-repairing waterborne woodware finishing coat, which is prepared from the following raw materials in parts by weight: 55-75 parts of self-crosslinked polyacrylic modified polyurethane resin, 0-10 parts of a pigment, 4-10 parts of a nano self-repairing assistant, 1-3 parts of nano silica dispersion, 2-8 parts of a coalescing agent, 0.75-3.1 parts of a function additive and 5-15 parts of water. According to the self-repairing waterborne woodware finishing coat designed aiming at the problems that the current waterborne paint is low in hardness, poor in scratch resistance and the like, self-repairing of micro cracks on the woodware surface can be achieved; the service life of the woodware is prolonged; and meanwhile, artificial repairing is avoided.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a self-repairing water-based wood topcoat. Background technique [0002] Woodenware is inevitably scratched during use or handling, resulting in a certain degree of scratch cracks, or cracks in the paint film due to changes in ambient temperature and humidity, which not only affect the beauty of woodware, but also reduce its service life. [0003] In recent years, the ecological environment around the world has been deteriorating, the government has paid more and more attention to environmental protection, and environmental protection laws and regulations have become increasingly perfect and strict. In terms of the use of wood lacquers, water-based paints have developed rapidly. Compared with traditional solvent-based paints, water-based paints have good environmental protection characteristics, low or zero VOC emissions, no pollution, no harm to the human body, and are more in ...
