Embodiment 1～7

[0043] A basic paint of hemp color stone imitation stone paint is prepared by the following method:

[0044] According to the dosage shown in Table 1, at a speed of 350r / min, add dispersant, defoamer, antifreeze, film-forming aid, titanium dioxide, kaolin, and hydrophobically modified ethyl glycol to deionized water in turn. Base cellulose and high molecular weight hydroxyethyl cellulose, stir and disperse for 5min; add pH regulator, under the rotating speed of 1500r / min, stir and disperse for 20min to obtain Mixture I;

[0045] Under the rotating speed of 800r / min, add emulsion, antiseptic, 10wt% protective glue aqueous solution, thickener and 80~120 mesh quartz sand successively to Mixture I, stir and disperse for 10min, obtain the hemp color stone imitation stone coating base paint.

[0046] The dosage of each raw material (unit: kg) of the base paint of the hemp-colored stone imitation stone coatings of Table 1 Examples 1-7

[0047]

[0048]

Embodiment 8

[0050] A basic paint of hemp color stone imitation stone paint is prepared by the following method:

[0051] According to the dosage shown in Example 2, at a rotational speed of 400 r / min, add dispersant, defoamer, antifreeze, film-forming aid, titanium dioxide, kaolin, and hydrophobically modified ethyl hydroxyl into deionized water in turn. Ethyl cellulose and high-molecular-weight hydroxyethyl cellulose were stirred and dispersed for 5 minutes; a pH regulator was added, and at a rotational speed of 1600 r / min, the mixture was stirred and dispersed for 20 minutes to obtain Mixture I;

[0052] Under the rotating speed of 1000r / min, add emulsion, preservative, 10wt% protective glue aqueous solution, thickener and 80-120 mesh quartz sand to Mixture I in turn, stir and disperse for 8min, to obtain Ma Cai stone imitation stone Base paint for paint.

Embodiment 9

[0054] A basic paint of hemp color stone imitation stone paint is prepared by the following method:

[0055] According to the dosage shown in Example 2, under the rotating speed of 200r / min, add dispersant, defoamer, antifreeze, film-forming aid, titanium dioxide, kaolin, hydrophobically modified ethyl hydroxyl into deionized water in sequence Ethyl cellulose and high-molecular-weight hydroxyethyl cellulose were stirred and dispersed for 8min; at a rotating speed of 1650r / min, a pH regulator was added, and the mixture was stirred and dispersed for 20min to obtain Mixture I;

[0056] Under the rotating speed of 950r / min, add emulsion, preservative, 10wt% protective glue aqueous solution, thickener and 80~120 mesh quartz sand successively to Mixture I, stir and disperse for 10min, to obtain Macai stone imitation stone Base paint for paint.

Abstract

This application relates to the field of imitation stone coatings, and specifically discloses a base paint for imitation stone coatings of hemp colored stone, a preparation method and an imitation stone coating of hemp colored stones. The base paint increases the content of emulsion, and the cellulose is selected from hydrophobic modified The combination of hydroxyethyl cellulose and high-molecular-weight hydroxyethyl cellulose significantly improves the toughness of the base paint, making the paint film continuous and dense, with a smooth surface and excellent stain resistance; the preparation method of the base paint is Add various additives, powders, hydrophobically modified ethyl hydroxyethyl cellulose and high molecular weight hydroxyethyl cellulose to the deionized water first, and stir at a low speed; Stir; then reduce the rotating speed to below 1000r / min, add emulsion, and make the base paint of hemp colored stone imitation stone coating; the base paint of the application cooperates granulation liquid, continuous phase, can prepare hemp color stone imitation stone coating , has the imitation stone effect of real stone paint, and the surface of the paint film is smooth, with excellent stain resistance.

Description

technical field [0001] The present application relates to the technical field of imitation stone coatings, and more particularly, to a base paint of hemp colored stone imitation stone paint, a preparation method and hemp colored stone imitation stone paint. Background technique [0002] Imitation stone paint is a kind of thick exterior wall decorative paint with decorative effect similar to marble and granite. The imitation stone coating has the characteristics of fire prevention, waterproof, acid and alkali resistance, pollution resistance, etc. It can effectively prevent the erosion of the building by the harsh external environment, thereby prolonging the life of the building. [0003] There are many types of imitation stone paint, among which the application of real stone paint is more common. Real stone paint is mainly made of natural granite and other crushed stone and stone powder as the main material, with synthetic resin emulsion as the main binder, and supplemented...
