Abstract

The invention discloses sand-containing colorful stone paint and a preparation method thereof, and relates to the technical field of architectural coatings. Raw materials of the stone paint comprisesa granulating liquid and a continuous phase, wherein the mass ratio of the granulating liquid to the continuous phase is (60-80):(40-20), the granulating liquid comprises color-matching base paint andsand, and the mass ratio of the color-matching base paint to the sand is 100:(50-80); the color-matching base paint comprises the following components: in percent by weight, 0.8-1.2% of hydrophobically modified cellulose, 0.2-0.4% of a defoamer, 0 .2-0.4% of a wetting agent, 0.5-0.7% of a film-forming assistant, 10-15% of filler, 0.1-0.2% of a multifunctional amine assistant, 0.3-0.5% of a preservative, 20-30% of an acrylic emulsion, 1-5% of color paste, 8-12% of pregel and the balance water. After curing and film formation are performed in the late stage, color points are clear and realistic, and the reality property of dry hanging marble and other natural stone can be achieved after the paint is coated on the outer wall, so that the decorative effect of buildings without accomplishing anything is shown; and through selection of the components and control on the ratios of the components, the stone paint has storage stability, and no layering and no precipitation occur after 6 monthsof storage is performed.

Description

technical field

[0001] The invention relates to the technical field of architectural coatings, in particular to a sand-containing colorful stone-like coating and a preparation method thereof. Background technique

[0002] Stone-like paint is a thick exterior wall decorative coating with a decorative effect similar to marble and granite. It is mainly formulated with particles of various colors. The buildings decorated with imitation stone paint have natural and real natural color, giving people an elegant, harmonious and solemn aesthetic feeling. It is suitable for indoor and outdoor decoration of various buildings, especially for decoration on curved buildings, which can receive vivid and return to nature effects. Stone-like paint has the characteristics of fire prevention, waterproof, acid and alkali resistance, pollution resistance, non-toxic, tasteless, strong adhesion, and never fades. It can effectively prevent the harsh external environment from eroding buildings and...

Examples

Embodiment 1

[0063]Embodiment 1: a kind of preparation method of sand-containing colorful imitation stone coating comprises the following steps:

[0064] Step 1, prepare pre-gel, mix preservative, magnesium aluminum silicate, water, and disperse for 60 minutes at a speed of 1500 rpm to obtain pre-gel, which includes the following components in weight percentage: preservative 0.1%; magnesium aluminum silicate 6%; the balance is water, and the main component of the preservative is Kathon.

[0065] Step 2, prepare the base paint, mix the hydrophobically modified cellulose, defoamer, wetting agent, film-forming aid, filler, and water and disperse evenly, the dispersion speed is 1700 rpm, and the dispersion time is 25 minutes. When the dispersion speed drops to 400 rpm, add multifunctional amine additives, preservatives, and acrylic emulsion to disperse evenly. The dispersion time is 6 minutes, and then slowly add pregel to disperse evenly. The dispersion speed is 850 rpm. 12 minutes to obtain...
