Colored inorganic thermal insulation mortar and preparation method thereof

Abstract

The invention provides colorful inorganic thermal insulation mortar and a preparing method thereof. The mortar is prepared from, by weight, 35-45% of colorful cement, 20-30% of ash-calcium powder, 15-25% of calcium carbonate, 1-2% of waterproof rubber powder, 1-2% of organic binder, 0.5-2% of water-retaining agent, 0.5-1% of anti-crack auxiliary and 4-6% of colorful glass beads. Compared with the prior art, by using the colorful inorganic thermal insulation mortar for replacing inorganic thermal insulation mortar, plastering anti-crack mortar layer and a finish coat layer can be omitted, and labor and materials are saved; the water absorption index is required to be smaller than or equal to 5%.

Description

technical field [0001] The invention relates to a colored inorganic thermal insulation mortar and a preparation method thereof. Background technique [0002] Colored decorative mortar has been widely used in the interior and exterior wall decoration of buildings instead of paint and ceramic tiles in developed countries. Colored decorative mortar is refined with polymer material as the main additive, together with high-quality mineral aggregates, fillers and natural mineral pigments. The thickness of the coating is generally between 1.5-2.5 mm, while the thickness of ordinary latex paint is only 0.1 mm, so it can obtain excellent texture and three-dimensional decorative effect. [0003] After retrieval, the prior patent application CN201610068074A discloses a nano-color thermal insulation mortar paint, especially a nano-color thermal insulation mortar paint that combines heat preservation, flame retardancy, sterilization, crack resistance, waterproof, weather resistance, and...

AI Technical Summary

Problems solved by technology

The prior application CN 102021985 A discloses a textured decorative brick for building exterior wall thermal insulation, but its preparation method is more complicated. At the same time, the production cost is higher than that of mortar, and the production cycle is long, which is not conducive to large-scale promotion and application.

In short, the existing technology basically has the problems of high production cost, complicated preparation and high water absorption rate.
