Abstract

The invention relates to a coating for outer walls and a preparation method thereof. The coating contains following components in parts by weight: 60 to 90 parts of acrylic acid ester emulsion, 25 to 40 parts of silica sol, 12 to 20 parts of pearl essence, 0.3 to 1 part of light chrome yellow, 25 to 45 parts of ash calcium powder, 20 to 40 parts of powdered steatile, 2 to 5 parts of hectorite, 1.3 to 3.2 parts of clay, 1.5 to 4 parts of aluminum sulfate, 0.6 to 1.5 parts of antifoaming agent, 4.5 to 12 parts of Texanol alcohol ester, 0.1 to 0.7 part of cuprous oxide and 50 to 85 parts of water. The coating for outer walls has the functions of water resistance, acid resistance, alkali resistance, freezing and thawing resistance, pollution and dust resistance, aging resistance and fire resistance, and also has the effects of mildew resistance and sterilization.

Description

technical field [0001] The invention relates to an exterior wall paint and a preparation method thereof, in particular to an exterior wall paint and a preparation method thereof. Background technique [0002] Most of the colored acrylic glossy latex paints used for exterior walls are thin coatings. It is a thin coating made of organic polymer materials as the main film-forming substance, plus different pigments, fillers and aggregates. It has the characteristics of water resistance, acid resistance, alkali resistance, and freeze-thaw resistance. Silica sol is added to the paint, which can make the paint firm and make the paint have the functions of anti-fouling, dust-proof, aging resistance, fire prevention and so on. If these two substances are combined, the resulting coating has a more complete function. The coatings currently on the market have imperfect functions and defects, so people will have difficulties in choosing. Contents of the invention [0003] Technical ...
