Problems solved by technology

With the continuous expansion of the application field of water-based wood coatings, the pattern of the wood base used is repeated, and the depth of the wood vessels is different, and the solid content of the water-based wood coatings itself determines that in the case of deep-tube substrates, it is necessary to add multiple layers of paint Film filling, which also seriously affects the overall effect of the paint film
[0003] In the specific construction process, the following problems are common: 1. Due to the lack of filling and multiple coverage of the primer, th

Example Embodiment

[0029] Example 2 A method for preparing woodware filler

[0030] This embodiment provides a method for preparing the woodware filler described in Embodiment 1, including:

[0031] A component:

[0032] In the low-speed dispersion state, add the oil-to-water-based castor oil resin into the tank, and then add water, film-forming additives, wetting agents, and defoamers in sequence under the dispersing conditions of 600-1000r / min for 10-20 minutes. To no oil shrinkage.

[0033] Component B:

[0034] Add dispersant and filler powder to the A group material under 300-800r / min dispersion conditions. After 25 minutes of dispersion, add rheological additives and slow-drying additives to continue dispersion for 10 minutes, filter canned.

Abstract

The invention relates to a high-filling transparent woodware filling agent and a preparation method thereof, wherein the filling agent comprises, by weight, 25.0-35.0 parts of an oil-modified aqueouscastor oil resin, 2.0-3.0 parts of a film-forming aid, 5.0-6.0 parts of a slow-drying aid, 0.5-3.0 parts of a wetting agent, 0.3-1.5 parts of an anti-foaming agent, 1.5-3.0 parts of a dispersant, 30.0-40.0 parts of a filler, 10.0-15.0 parts of water, and 1.0-4.0 parts of a rheological aid. According to the present invention, the high-filling transparent woodware filling agent has good filling performance, can effectively reduce the primer coating at least once, further has advantages of good transparency and good adhesion, can be used for a long time, has the adhesion of more than grade one, can strengthen the adhesion between the coating and the substrate in the overall coating, and can further strengthen the transparency of the primer coating and the overall coating effect.

Description

technical field [0001] The invention belongs to the technical field of wood coatings, and in particular relates to a high-filling transparent wood filler and a preparation method thereof, which are specially used to increase the filling and plumping performance of water-based coatings. Background technique [0002] At present, in recent years, the level of my country's water-based wood coatings industry has improved rapidly, but it is still slightly insufficient in the richness of functional products. With the continuous expansion of the application field of water-based wood coatings, the pattern of the wood base used is repeated, and the depth of the wood vessels is different, and the solid content of the water-based wood coatings itself determines that in the case of deep-tube substrates, it is necessary to add multiple layers of paint Film filling, which also seriously affects the overall effect of the paint film. [0003] In the specific construction process, the follow...
