Embodiment 1-1

[0045] A kind of outdoor water-based wooden ware matte clear finish, is formulated by following raw materials according to following weight ratio:

[0046]

[0047]

[0048] The preparation method of this outdoor water-based wooden ware matte varnish comprises the following steps carried out in sequence:

[0049](1) Start the disperser and adjust the speed to 400 rpm. At this speed, first add 7.3 parts of water, 0.1 part of water-based multifunctional additive and 1 part of water-based matting powder, and then adjust the speed of the disperser to 1800 rpm. Disperse for 10 minutes;

[0050] (2) Then adjust the speed of the disperser to 800 rpm, and check whether the fineness of the paint liquid is ≤30 μm. If the fineness is >30 μm, proceed to step (3);

[0051] Through the above steps, usually the fineness will be ≤30μm. If it is not reached, it can be dispersed for a period of time before testing. If the long-term dispersion test fails to meet the requirements, it means...

[0062] A kind of outdoor water-based wooden ware matte clear finish, is formulated by following raw materials according to following weight ratio:

[0063]

[0064] The preparation method of this outdoor water-based wooden ware matte varnish comprises the following steps carried out in sequence:

[0065] (1) Start the disperser and adjust the speed to 450 rpm. At this speed, first add 5.1 parts of water, 0.15 parts of water-based multifunctional additives and 3 parts of water-based matting powder, and then adjust the speed of the disperser to 1900 rpm. Disperse for 13 minutes;

[0066] (2) Then adjust the speed of the disperser to 900 rpm, and check whether the fineness of the paint liquid is ≤30 μm. If the fineness is >30 μm, proceed to step (3);

[0067] Through the above steps, usually the fineness will be ≤30μm. If it is not reached, it can be dispersed for a period of time before testing. If the long-term dispersion test fails to meet the requirements, it means that t...

Abstract

The invention relates to a woodenware paint and a preparation method, and especially relates to an outdoor aqueous woodenware matte clean finishing coat and its preparation method, which belong to the paint field for building decoration. The provided outdoor aqueous woodenware matte clean finishing coat comprises the following raw materials by weight: 10-14.6 parts of water, 0.1-0.15 parts of aqueous multifunctional auxiliary agent, 1-5 parts of aqueous flatting silica, 73-78 parts of aqueous pure acrylic acid emulsion, 4-5 parts of film forming auxiliary agent and 0.3-0.5 parts of aqueous levelling agent. The prepared outdoor aqueous woodenware matte clean finishing coat has excellent weatherability, can protect base materials from being destroyed; the usage is simple, the construction tolerance is wide and the application scope is wide.

Description

technical field [0001] The invention relates to a wood varnish and a preparation method thereof, in particular to an outdoor water-based wood matte varnish and a preparation method thereof, belonging to the field of architectural decoration paints. Background technique [0002] Outdoor wood is mainly composed of cellulose (Cellulose) and lignin (Lignin). When exposed to ultraviolet light and short-wave visible light with a wavelength of ≤440nm, lignin is decomposed into water-soluble components. The decomposed lignin can be taken away by water during the dry-wet change process. In this way, when the wood cell wall is destroyed, the lignin is easily leached away, allowing light to enter the relatively empty wood cells. Reflections make the wood grayish, and fully weathered wood appears silvery gray (the natural color of lignocellulose). Water is the number one enemy of wood, especially when the moisture content of wood changes intermittently. According to the experiment, i...
