Abstract

The invention relates to color cement roof paint and its preparation technology. Its material constituents and weight percentages are as follows: acrylic resin 20-45%, pigment or dye 0.5-15%, auxiliary 0.1-3%, and solvent 45-78%. Its preparation technology adopts resin and paint manufacturing steps. Compared with the current technique, it emphasizes glass temperature control more to make the product have better weathering and water resistances. Thus it can be used in outdoor cement product, especially for the protection and decoration of the cement roof tile surface.

Description
