preparation example Construction

[0065] The present invention also provides a kind of preparation method of above-mentioned genuine stone paint, comprises the following steps:

[0066] The emulsion, natural sand and calcium lime powder are mixed.

[0067] Preferably, for the real stone paint containing emulsion, natural sand, filler, lime lime powder, water, dispersant, wetting agent, defoamer, film-forming aid, pH regulator and preservative in the formula, its preparation method comprises Follow the steps below;

[0068] (1) Pre-mixing: Mix part of water, dispersant, wetting agent, defoamer, film-forming aid and pH regulator, stir, disperse for 1-5 minutes, add emulsion and stir, and prepare the mixture after stirring a.

[0069] (2) Dispersion: In the state of stirring, add filler to mixture A, stir for 15-20 minutes, add natural sand, continue stirring to obtain mixture B.

[0070] (3) Viscosity adjustment: under stirring state, add preservative and remaining water into mixture B, stir and mix to prepar...

Embodiment 1

[0076] This embodiment provides a genuine stone paint and a preparation method thereof.

[0077] (1) In parts by weight, the raw materials for the preparation of real stone paint 1 are as follows:

[0078]

[0079]

[0080] Among them, the EZ3010 emulsion is a VAE emulsion, and the glass transition temperature of the polymer is about 6°C.

[0081] (2) Preparation of real stone paint 1:

[0082] ①Pre-mixing: Disperse 90% of water, dispersant, wetting agent, 50% of defoamer, film-forming aid, and pH regulator for 1-5 minutes, then add emulsion and stir, and then prepare mixture A .

[0083] ② Dispersion: Add titanium dioxide and heavy calcium to mixture A under stirring, add natural sand after stirring for 15-20 minutes, and continue stirring to obtain mixture B.

[0084] ③ Viscosity adjustment: Add preservative, remaining water and remaining defoamer to the stirring mixture B, and stir evenly to obtain real stone paint 1.

Embodiment 2

Abstract

The invention relates to a stone-like coating and a preparation method thereof. The stone-like coating is prepared from the following raw materials in parts by weight: 8-30 parts of emulsion, 10-30 parts of natural sand, 2-20 parts of ash calcium powder and 20-50 parts of filler. The emulsion contains a polymer, and the glass transition temperature of the polymer is -15 DEG C to 60 DEG C. The emulsion is selected from VAE emulsion. The particle size of the natural sand is 70-100 meshes. The stone-like coating is very environment-friendly, a formed coating film very much like stone and is high in hardness, high in flatness, fine and smooth in touch feeling, good in adhesive force, smooth and clean in surface and full in sense organ, and the stone-like coating has a wide application prospect.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a real stone paint and a preparation method thereof. Background technique [0002] As people's awareness of environmental protection gradually strengthens, harmful substances such as volatile organic compounds, benzene series and formaldehyde brought by interior decoration have become the focus of consumers' attention. The development of coatings tends to be green and environmentally friendly. Water-based coatings are gradually replacing oil-based coatings in architectural coatings due to their green and environmentally friendly characteristics. [0003] The real stone paint made of sand-containing paint is a kind of water-based paint. It is mainly formulated with natural stone powder of various colors. It can be applied to imitation stone materials for building exterior walls, also known as liquid stone. Because of its decorative effect similar to marble or granite, the decorated buildi...
