Description
Technical Field
The invention relates to flexible color mortar for soft stone finished product paste and a preparation method thereof, belonging to the field of paint.
Background
Color mortar has been widely used in place of paint and tile for interior and exterior wall decoration of buildings. The color mortar is prepared by taking polymer materials as main additives and adding high-quality mineral aggregate, filler and natural mineral pigment. The granular or powder material is produced through physical mixing in certain proportion, and the granular or powder material is transported to site in bagged or bulk form and mixed with water to obtain the product. The color mortar is a paint with marble, granite texture, color and texture decorative effect, and the thickness of the paint is generally 1.5-2.5 mm, so that excellent texture and three-dimensional decorative effect can be obtained.
However, when the existing colored mortar is adopted for outer wall decoration, the binding force with the wall body is not high, and frost cracking and falling easily occur in winter. Especially in the 'three north' areas of China, the winter duration is long, the engineering construction period is shortened, the site construction efficiency is low, and the quality is difficult to guarantee. And when the air temperature is lower than 0 ℃, the freezing of the mortar mixing water at the negative temperature can not only stop the hydration of cement in the mortar mixing water, but also cause the damage of the structure of cement hydration products due to the volume expansion generated by water icing. However, the color decorative mortar in the current market has the problems of easy falling, fading, cracking and the like. However, the color mortar has the defects of large smell, difficult storage in winter, difficult corrosion resistance in summer and the like in the field construction process of the color mortar.
