Embodiment 1

[0013] The preparation method of a kind of water-based white pearl finish paint described in the present embodiment 1 may further comprise the steps:

[0014] (1) Dilute 0.4 parts of thickener with 5% deionized water by weight to make a paste, add 0.1 parts of additives, stir evenly, and obtain mixed solution A;

[0015] (2) Add 0.3 parts of defoamer to 50 parts of water-based resin, stir at <1000r / min for 15 minutes, then add 0.1 part of pearlescent powder to obtain mixed solution B;

[0016] (3) Within 5 minutes, add 4 parts of solvent, deionized water, and 0.1 part of ammonia water dropwise to mixed solution B to obtain mixed solution C; the deionized water used in this step and the deionized water used in step (1) total 14 copies;

[0017] (4) Add the mixed solution A into the mixed solution C, and stir for 10 minutes at a rotation speed of 200 r / min to obtain the water-based white pearlescent topcoat.

Embodiment 2

[0019] A kind of preparation method of water-based white pearl finish paint described in present embodiment 2, comprises the following steps:

[0020] (1) Dilute 0.8 parts of thickener with 15% deionized water by weight to make a paste, add 0.4 parts of additives, stir well, and obtain mixed solution A;

[0021] (2) Add 0.7 parts of defoamer to 60 parts of water-based resin, stir at <1000r / min for 30 minutes, then add 0.5 parts of pearlescent powder to obtain mixed liquid B;

[0022] (3) Within 15 minutes, add 10 parts of solvent, deionized water, and 0.3 parts of ammonia water dropwise to mixed solution B to obtain mixed solution C; the deionized water used in this step and the deionized water used in step (1) total 28 copies;

[0023] (4) Add the mixed solution A into the mixed solution C, and stir for 30 minutes at a rotation speed of 400 r / min to obtain the water-based white pearlescent topcoat.

Abstract

The invention discloses water-based white pearly finish paint which is composed of the following components in parts by weight: 50-60 parts of water-based resin, 0.1-0.5 part of pearly powder, 0.3-0.7 part of an antifoaming agent, 4-10 parts of a solvent, 0.1-0.3 part of ammonia water, 0.4-0.8 part of a thickening agent, 0.1-0.4 part of an auxiliary and 14-28 parts of deionized water. The white pearly finish paint has the advantages of good water resistance, high glossiness, yellowing resistance, high acid-base resistance, high fullness, good weather resistance, energy conservation and environment protection.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based white pearl finish paint and a preparation method thereof. Background technique [0002] The top coat, also known as the finish coat, is the last coat of paint applied in a multi-layer coating. It should have good resistance to external conditions, and must have the necessary hue and decoration, and have a protective effect on the base coat. The topcoat used outdoors should use a coating with excellent weather resistance. The decorative effect and weather resistance of the topcoat not only depend on the paint base used, but also have a great relationship with the pigments used and the preparation process. With people's further understanding of the environmental protection, decorative and protective functions of coatings, consumers have put forward higher requirements for decorative styles. Pearlescent pigment is a characteristic pigment, named for its unique luster and ch...
