Embodiment 1

[0029]

[0030] Add components 1 to 9 sequentially with low-speed stirring, and disperse at high speed until the fineness is less than 50 μm. Then, under low-speed stirring, add the remaining components and adjust to 100g with water to complete the preparation of latex base paint.

[0031] The coating properties are as follows:

[0032]

Embodiment 2

[0034]

[0035] After adding components 1 to 9 in sequence with low-speed stirring, disperse at high speed until the fineness is less than 50 μm, then, under low-speed stirring, add the remaining components and adjust to 100 with water to complete the preparation of latex base paint.

[0036] The coating properties are as follows:

[0037]

Embodiment 3

[0039]

[0040] Add components 1 to 8 in turn with low-speed stirring, and disperse at high speed until the fineness is less than 25 μm. Then, under low-speed stirring, add the remaining components and adjust to 100 with water to complete the preparation of latex base paint.

[0041] The coating properties are as follows:

Abstract

The invention provides emulsion foundation paint for an outer wall. The emulsion foundation paint for the outer wall comprises the following components in parts by weight: 8-20 parts of water, 2-4 parts of cosolvent, 0.5-1.2 parts of dispersing agent, 0.1-0.25 part of wetting agent, 0-40 parts of pigment, 0-65 parts of filler, 8-70 parts of emulsion, 0.2-1 part of thickening agent, and 0.1-0.4 part of defoaming agent. Meanwhile, the invention also provides a preparation method of emulsion foundation paint for the outer wall, and in particular stipulates the adding order and mixing condition of materials. The emulsion foundation paint for the outer wall, which is prepared by the invention, has the advantages of water resistance and alkaline resistance, meanwhile the emulsion foundation paint for the outer wall also can keep good performances under the ultraviolet effect, and also has the functional characteristics of freezing and thawing resistance, and moreover, the emulsion foundation paint is nontoxic and is low in VOC (volatile organic compounds), can meet the application requirements of the current outer wall, and has positive environment friendly significance.

Description

【Technical field】 [0001] The invention belongs to the technical field of chemical coatings, in particular to a latex base paint for exterior walls and a preparation method thereof. 【Background technique】 [0002] In developed countries in Europe and America, the penetration rate of water-based paint has reached more than 80%. But in our country, the development of water-based paint is just on the highway. Although it is still in a weak position, its share is growing rapidly. In the near future, water-based paint will occupy the mainstream paint market. The main advantages of water-based paints are: 1. Environmentally friendly oil-based paints are mainly nitro paints and polyester paints. A large amount of organic solvents are added during the dilution process, and they stay indoors for a long time, which will cause harm to human health. Therefore, oil-based paint is also dubbed the title of "invisible killer". Research has found that a larger part of toxic carcinogens repr...
