Abstract

The invention discloses an architectural ornament coating which comprises the following components in parts by weight: 30-50 parts of waterborne polyurethane, 3-8 parts of AS resin, 0.5-1.5 parts of carboxymethylcellulose, 30-60 parts of rare-earth sulfur oxide, 85-100 parts of fluorine halide, 3-6 parts of heat stabilizer, 0.9-4.9 parts of chemical resisting modifier, 15-20 parts of 4-hydroxy-3-metoxybenzene alcohol, 10-25 parts of heat-conductive filler, 10-18 parts of 2-hydroxy citric acid, 0.75-2.65 parts of infrared reflecting titanium dioxide, 0.4-0.6 part of light stabilizer, 0-0.8 part of coupling agent, 0.7-4.3 parts of accelerant, 10.4-23.6 parts of color paste, 4-8 parts of carboxymethylcellulose, 7-13 parts of toluene diisocynate, 25-30 parts of 3-cyclohexene-1-methyl alcohol, 5-8 parts of allyl dimethyl malonate and 3-10 parts of additives. The weight-average molecular weight of AS resin is 3-10W. The content of acrylonitrile in the AS resin is 20-35%. The fluorine-containing additive is selected as the chemical resisting modifier. The architectural ornament coating has excellent coloring property and is difficult to crack and fade.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building decoration paint. Background technique [0002] Architectural decorative coatings have the functions of decoration, protection and habitability improvement. The proportions of various functions vary due to different purposes. The decorative function is to improve the appearance value of a building by beautifying it. [0003] With the development of the economy and the continuous progress of the construction industry, there are higher requirements for the performance of architectural decorative coatings. The shape of the object itself matches the size and shape of the base material itself, and it has higher requirements for mildew resistance, fire prevention, thermal insulation, corrosion resistance, sound insulation, and sound absorption. However, the general performance stability of architectural decorative coatings on the market is not high, which cannot ...
