Embodiment 1～7

[0043] A kind of basic paint of hemp colored stone imitation stone paint, adopts following method to prepare:

[0044] According to the dosage shown in Table 1, at the speed of 350r / min, add dispersant, defoamer, antifreeze, film-forming aid, titanium dioxide, kaolin, hydrophobically modified ethyl hydroxyethyl Base cellulose and high molecular weight hydroxyethyl cellulose were stirred and dispersed for 5 minutes; a pH regulator was added, and at a rotating speed of 1500r / min, stirred and dispersed for 20 minutes to obtain mixture I;

[0045] At the speed of 800r / min, add emulsion, preservative, 10wt% protective glue aqueous solution, thickener and 80-120 mesh quartz sand to the mixture I in sequence, stir and disperse for 10min, and obtain the mosaic stone imitation stone coating base paint.

[0046] Each raw material dosage (unit: kg) of the base paint of the hemp colored stone imitation stone coating of table 1 embodiment 1~7

[0047]

[0048]

Embodiment 8

[0050] A base paint for hemp-colored stone imitation stone paint, which is prepared by the following method:

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

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

Embodiment 9

[0054] A kind of basic paint of hemp colored stone imitation stone paint, adopts following method to prepare:

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

Abstract

The invention relates to the field of stone-like coatings, and particularly discloses a basic paint of a spotted colored stone-like coating, a preparation method and the spotted colored stone-like coating. The basic paint improves the content of emulsion, cellulose is compounded by hydrophobic modified ethyl hydroxyethyl cellulose and high-molecular-weight hydroxyethyl cellulose, the toughness of the basic paint is remarkably improved, the prepared paint film is continuous and compact, the surface is smooth, and the stain resistance is excellent; the preparation method of the basic paint comprises the following steps: firstly, adding auxiliaries, a powder, the hydrophobic modified ethyl hydroxyethyl cellulose and the high-molecular-weight hydroxyethyl cellulose into the deionized water, and stirring at a low speed; then adding a pH regulator, and carrying out high-speed stirring at a rotating speed of 1500r / min; reducing the rotating speed to 1000 r / min or below, and adding the emulsion to prepare basic paint of the spotted colored stone-like coating; the spotted colored stone-like coating can be prepared by matching the basic paint with a granulation liquid and a continuous phase, the spotted colored stone-like coating has the stone imitation effect of real stone paint, the surface of a paint film is smooth, and has excellent stain resistance.

Description

technical field [0001] The present application relates to the technical field of imitation stone coatings, more specifically, it relates to a base paint for imitation stone coatings of hemp-colored stones, a preparation method and the imitation stone coatings of hemp-colored stones. Background technique [0002] Stone-like paint is a kind of thick exterior wall decorative paint with a decorative effect similar to marble and granite. It is mainly formulated with natural stone powder of various colors, and is mostly used to create the stone-like effect of building exterior walls. Stone-like coatings have the characteristics of fire prevention, waterproof, acid and alkali resistance, and pollution resistance, which can effectively prevent the external harsh environment from eroding buildings, thereby prolonging the life of buildings. [0003] There are many kinds of imitation stone paints, among which the application of real stone paints is more common. Real stone paint is mai...
