Problems solved by technology

However, the gloss of the water-based wood paint film is not easy to reduce. When the gloss drops to a certain level, even if the amount of matting powder is increased, the gloss will not be lower, and the paint film will turn white easily, thereby reducing the transparency of the paint film.
In addition, in the matte system, the glossiness of the water-based wood paint film is not easy to reduce, and the surface of the paint film is not scratch-resistant, and it is easy to leave bright marks. These problems have seriously restricted the development of matte water-based wood paint

Embodiment 1-1

[0044] A kind of water-based matte varnish for woodware is formulated by the following raw materials according to the following weight ratio:

[0045]

[0046]

[0047] The preparation method of this water-based woodware matte varnish comprises the following steps carried out in sequence:

[0048] (1) Start the disperser and adjust the speed to 400 rpm. At this speed, first add 4.3 parts of water, 0.1 part of water-based multifunctional additive, 0.3 part of water-based defoamer and 0.5 part of water-based matting powder, and then adjust the disperser Speed ​​to 1800 rpm, disperse for 10 minutes;

[0049] (2) Adjust the speed of the disperser to 800 rpm, and check whether the fineness of the paint liquid is ≤30 μm, and if the fineness is ≤30 μm, proceed to step (3);

[0050] Through the above steps, the fineness will usually be ≤30μm. If it is not achieved, it can be dispersed for a period of time before testing. If the long-term dispersion test fails to meet the requir...

Abstract

The invention relates to a woodenware paint and a preparation method, and especially relates to an aqueous woodenware matte clean finishing coat and its preparation method, which belong to the paint field for building decoration. The provided aqueous woodenware matte clean finishing coat comprises the following raw materials by weight: 4-6.5 parts of water, 0.1-0.15 parts of aqueous multifunctional auxiliary agent, 0.2-0.4 parts of aqueous antifoaming agent, 0.5-1.5 parts of aqueous flatting silica, 18-22 parts of aqueous polyurethane, 57-62 parts of aqueous pure acrylic acid emulsion, 5-6 parts of film forming auxiliary agent, 2-4 parts of aqueous micro powder wax and 0.4-0.7 parts of aqueous wetting levelling agent. The prepared aqueous woodenware matte clean finishing coat has the advantages that the glossiness of a paint film is easily reduced, and the scratch resistance capability of the surface is strong.

Description

technical field [0001] The invention relates to a wood varnish and a preparation method thereof, in particular to a water-based wood matt varnish and a preparation method thereof, belonging to the field of architectural decoration paints. Background technique [0002] Today, as people's awareness of environmental protection is increasing, the requirements for environmental protection of coatings are also getting higher and higher. Water-based wood paints are gradually replacing solvent-based paints as protective coatings for wood products due to their lower VOC (volatile organic compound) content. Because it uses water as a solvent and is easy to use, it has been used more and more in the DIY wood coating market and the industrial wood coating market. However, the gloss of the water-based wood paint film is not easy to reduce. When the gloss drops to a certain level, even if the amount of matting powder is increased, the lower gloss will not be obtained, and the paint film ...
