Abstract

The invention relates to heat-preserving decorative mortar which comprises the following components in parts by weight: 180-220 parts of cement, 30-70 parts of fly ash, 560-600 parts of sand, 70-100 parts of heavy calcium carbonate, 30-60 parts of heat-preserving aggregate, 3-9 parts of bentonite, 4-8 parts of wood fiber, 2-7 parts of water repellent, 2-5 parts of alkalization inhibitor, 0.5-4 parts of cellulose ether, 6-15 parts of rubber powder and 1-30 parts of pigment. A preparation method thereof comprises the following steps of: firstly uniformly mixing the cement, the fly ash, the sand, the heavy calcium carbonate, the bentonite, the wood fiber, the water repellent, the alkalization inhibitor, the cellulose ether, the rubber powder and the pigment, subsequently adding the heat-preserving aggregate, and then mechanically and uniformly mixing to prepare the heat-preserving decorative mortar. The invention has the advantages of heat preservation, heat insulation, strong hydrophobic property, environmental protection, no pollution, and the like.

Description

technical field [0001] The invention relates to a building material, in particular to a mortar for exterior wall finishes, and more specifically to a heat-preservation decorative mortar which uses heat-retaining aggregates to make it play a decorative role and also has heat-insulation and heat-insulation functions and its Preparation. Background technique [0002] Decorative mortar has been widely used in European exterior wall finishing systems in the last century. It has replaced paint and facing bricks with its excellent characteristics and has become the best choice for finishing layers. Its self-weight is lighter than that of facing bricks, which increases the safety of the building's exterior wall structure. It can also change the wall surface by selecting templates and tools with different graphics, and applying different operations such as dragging, rolling, scraping, twisting, and kneading. Various patterns such as embossing, corrugation, and wood grain can be form...
