preparation example Construction

[0028] A preparation method of antique anti-aging exterior wall paint, adopting the following steps:

[0029] Mix the acrylic emulsion, filler, edible sucrose, and hydroxymethyl cellulose evenly under stirring to obtain a mixed solution;

[0030] Stir and mix the pigment, penetrating agent, dispersant, film-forming aid, and deionized water evenly, then add to the aforementioned mixed solution, and continue to stir evenly to prepare an antique anti-aging exterior wall paint.

[0031] The following are more detailed implementation examples, through which the technical solutions of the present invention and the technical effects that can be obtained are further described.

Embodiment 1

[0033] An antique anti-aging exterior wall paint, which is prepared from the following components and raw materials in parts by weight:

[0034] Pure acrylic emulsion 100, tartrazine pigment 2, talcum powder 40, edible sucrose 16, hydroxymethyl cellulose 10, penetrant fatty alcohol polyoxyethylene ether 0.5, dispersant benzenesulfonic acid formaldehyde condensation polymer 2, film-forming agent propylene glycol Methyl ether acetate 1, deionized water 40. This kind of coating adopts following method to prepare:

[0035] (1) acrylic acid emulsion, filler, edible sucrose, and hydroxymethyl cellulose are mixed under stirring to obtain a mixed solution;

[0036] (2) Stir and mix the pigment, penetrating agent, dispersant, film-forming aid, and deionized water evenly, then add to the aforementioned mixed solution, and continue to stir evenly to prepare an antique anti-aging exterior wall coating.

Embodiment 2

[0038] An antique anti-aging exterior wall paint, which is prepared from the following components and raw materials in parts by weight:

[0039] Acrylic emulsion 100, titanium dioxide pigment 5, filler 45, edible sucrose 15, hydroxymethyl cellulose 12, penetrant fatty alcohol polyoxyethylene ether 1, dispersant lignosulfonate 2, film-forming aid propylene glycol butyl ether 3, Deionized water 60.

[0040] The added acrylic emulsion is a mixture of silicon-acrylic emulsion and styrene-acrylic emulsion, and the filler is a mixture of lime and fly ash. Among them, the lime is the powder that is sieved with a fineness of 0.9mm, and the fly ash is the powder that is sieved with a square hole of 45μm. This kind of fineness filler is used together with edible sucrose, especially suitable for ancient building walls. Or use it on the antique exterior wall, which can improve the bonding performance of the wall, and the surface strength of the coating is good.

Abstract

The invention relates to an antique anti-aging exterior wall paint and a preparation method thereof. The paint is prepared from, by weight, 100 parts of polyacrylic emulsion, 2-10 parts of pigment, 35-45 parts of filler, 15-20 parts of edible sucrose, 10-20 parts of hydroxymethyl cellulose, 0.5-5 parts of a penetrant, 1-3 parts of a dispersing agent, 1-3 parts of a coalescing agent and 40-80 partsof deionized water. The polyacrylic emulsion, the filler, the edible sucrose and the hydroxymethyl cellulose are stirred and mixed uniformly to obtain a mixture; the pigment, the penetrant, the dispersing agent, the coalescing agent and the deionized water are stirred, mixed uniformly and then added into the above mixture, and uniform stirring continues to obtain the antique anti-aging exterior wall paint. Compared with the prior art, the weather resistance of the paint can be improved, and the antique effect is good.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an antique anti-aging exterior wall coating and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards in our country, people's requirements for quality of life and aesthetic taste have also increased. The visual effects of ancient buildings are simple and beautiful, and are loved by modern people. If it is possible to provide a coating that is close to the texture of ancient architecture, it will certainly be able to meet people's antique decorative requirements for exterior walls to a certain extent. However, there are no reports of such coatings at present. [0003] In addition, for the coatings of antique-style buildings, it is also necessary to show the visual effects of artificial stone imitation, wood imitation, antique and old-fashioned, which has further requirements for coatings.
