Problems solved by technology

[0004] However, the existing titanium dioxide slurry preparation process has the following problems: due to the introduction of cellulose during the high-speed dispersion of titanium dioxide, and the limited addition of beating water in the formulation system, the titanium dioxide cannot be well wetted, resulting in the dispersion of titanium dioxide It dries quickly, and it is easy to form secondary flocculation. The longer the dispersion time, the more flocculation of titanium dioxide slurry, so that titanium dioxide cannot be well dispersed into the whole system, resulting in poor system stability; in addition, the pigment content of titanium dioxide slurry is generally Both are less than 70%, and the slurry system is easy to delaminate, causing the problem of re-dispersion at high speed when adding

Embodiment 1-1

[0036] A kind of water-based wood varnish titanium dioxide is formulated by following raw materials according to the following weight ratio:

[0037]

[0038] The preparation method of this water-based wood varnish titanium dioxide comprises the following steps carried out in sequence:

[0039] Start the disperser and adjust the speed to 700 rpm. At this speed, slowly add 13 parts of water, 5 parts of dispersant, 0.5 part of wetting agent, 0.5 part of defoamer, 2.0 parts of co-solvent and 70 parts of titanium dioxide, Then adjust the speed of the disperser to 1800 rpm, disperse for 15 minutes until the slurry is uniform, and detect the fineness of the paint solution to be ≤40 μm.

Embodiment 1-2

[0041] A kind of water-based wood varnish titanium dioxide is formulated by following raw materials according to the following weight ratio:

[0042]

[0043] The preparation method of this water-based wood varnish titanium dioxide comprises the following steps carried out in sequence:

[0044] Start the disperser and adjust the speed to 800 rpm. At this speed, slowly add 14 parts of water, 5 parts of dispersant, 0.5 part of wetting agent, 0.5 part of defoamer, 2.0 parts of co-solvent and 73 parts of titanium dioxide. Then adjust the speed of the disperser to 1800 rpm, disperse for 20 minutes until the slurry is uniform, and detect the fineness of the paint solution ≤ 40 μm.

Embodiment 1-3

[0046] A kind of water-based wood varnish titanium dioxide is formulated by following raw materials according to the following weight ratio:

[0047]

[0048] The preparation method of this water-based wood varnish titanium dioxide comprises the following steps carried out in sequence:

[0049] Start the disperser and adjust the speed to 750 rpm. At this speed, slowly add 13 parts of water, 5.5 parts of dispersant, 0.45 parts of wetting agent, 0.6 parts of defoamer, 2.5 parts of co-solvent and 75 parts of titanium dioxide. Then adjust the speed of the disperser to 1900 rpm, disperse for 18 minutes until the slurry is uniform, and detect the fineness of the paint solution to be ≤40 μm.

Abstract

The invention relates to a woodenware paint and a preparation method, and especially relates to aqueous woodenware paint titanium white slurry and its preparation method, which belong to the paint field for building decoration. The provided aqueous woodenware paint titanium white slurry comprises the following raw materials by weight: 13-14 parts of water, 5-6 parts of dispersant, 0.45-0.55 parts of wetting agent, 0.5-0.6 parts of antifoaming agent, 2.0-2.5 parts of cosolvent and 70-75 parts of titanium dioxide. The prepared aqueous woodenware paint titanium white slurry has good system stability, good moisture retention and difficult secondary flocculation, addition of the slurry can be carried out by simple stirring, so that the production efficiency is effectively increased.

Description

technical field [0001] The invention relates to a titanium white paste and a preparation method thereof, in particular to a water-based wood paint titanium white paste and a preparation method thereof, and belongs to the field of architectural decoration coatings. Background technique [0002] In recent years, with the progress of the economy and the deterioration of the environment, people have higher and higher requirements for environmental protection and healthy life. More and more companies have begun to try to make water-based wood paint. [0003] However, the production problem of water-based wood white finish paint has been entangled every engineer. In order to obtain a stable dispersion of titanium dioxide, in the water-based paint formulation system, titanium dioxide is usually dispersed in water to make a slurry, and then the slurry The material is added to the emulsion to make a paint. [0004] However, the existing titanium dioxide slurry preparation process ha...
