Real stone lacquer and preparation method and construction method thereof

Abstract

The invention belongs to the technical field of building materials, and particularly relates to real stone lacquer and a preparation method and a construction method thereof. The real stone lacquer isprepared from sealing priming lacquer, middle layer lacquer and finish lacquer, wherein the sealing priming lacquer is prepared from the following raw materials in parts by weight: 30 to 36 parts ofalkali resistant emulsion, 8 to 12 parts of silicon sol, 0.8 to 1.2 parts of texanol, 0.8 to 1.2 parts of ammonium hydroxide and 50 to 60 parts of deionized water; the middle layer lacquer is preparedfrom the following raw materials in parts by weight: 180 to 220 parts of emulsion, 600 to 800 parts of natural color sand, 8 to 12 parts of texanol, 1 to 2 parts of ammonium hydroxide, 12 to 18 partsof thickening agents, 1 to 3 parts of antifoaming agents, 1 to 3 parts of sterilizing agents and 60 to 80 parts of deionized water; the finish lacquer is prepared from the following raw materials inparts by weight: 600 to 800 parts of emulsion, 200 to 400 parts of deionized water, 2 to 4 parts of antifoaming agents and 1 to 2 parts of ammonium hydroxide. The real stone lacquer has the advantagesthat the performance of water-resistance, salt-resistance and alkali-resistance is high; the reasonable color sand particle size grading is used, so that the sand falling phenomenon is obviously reduced; in addition, the preparation and construction methods are simple and are suitable for large-scale popularization and use.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a real stone paint and a preparation method and a construction method thereof. Background technique [0002] Natural stone is often used in the construction of traditional building exterior walls. Natural stone has a colorful and natural texture appearance, but its disadvantages are heavy weight, increased load on the wall, complex construction and brittle cracks, and there are many unsafe factors. have limited their application to some extent. Real stone paint is a kind of imitation stone paint formulated with various colors of stone powder, emulsion for architectural coatings and various additives. It not only has a decorative effect similar to marble and granite, but also has good acid and alkali resistance. , Pollution resistance, strong adhesion, light fading and other characteristics, can effectively prevent the external harsh environment from erodin...

Problems solved by technology

The Chinese invention patent with the publication number CN107652813A discloses a preparation method of a real stone paint that is not easy to drop sand. This invention only prevents natural sand from falling off by enhancing the bonding force between natural sand and silicon-acrylic emulsion, and does not The gradation of different particle sizes in sand and gravel is explained, and the effect of preventing sand falling still needs to be improved
