Abstract

The invention belongs to the technical field of building materials, and in particular relates to a dry material for a thermal insulation wall decoration layer, mortar and a wall. The dry material for the thermal insulation wall decoration layer provided by the present invention comprises the following components by weight: 340-550 parts of cement; 450-660 parts of sand; 1-80 parts of mineral active admixture; 2-60 parts of high molecular polymer ; 2.3-21 parts of admixture; 0-30 parts of pigment, 1-3 parts of coco-based monoethanolamide polyoxyethylene ether. The present invention can make the thermal insulation wall decorative layer material have high strength, compressive strength ≥ 40MPa, high water repellency, mass water absorption ≤ 3%, and area water absorption ≤ 155g / m through the coordination between components and dosage adjustment. 2 , low efflorescence, as an exterior wall decoration material, the durability is ≥50 years, which solves the problem that the service life of the wall finish layer is less than 25 years. In addition, the problem of efflorescence is a "cancer" that is difficult to cure in mortar. The present invention uses the component coconut oil monoethanolamide polyoxyethylene ether in combination with other components to simultaneously solve the problem of efflorescence and uneven dispersion of pigments. flower problem.

Description

technical field [0001] The invention belongs to the technical field of building materials, and particularly relates to a dry material, mortar and a wall for a decorative layer of a thermal insulation wall. Background technique [0002] Building thermal insulation is an important aspect of saving energy, improving living environment and using functions. The proportion of building energy consumption in the total human energy consumption is generally 30-40%, and most of it is the energy consumption of heating and air conditioning, so building energy saving is of great significance. [0003] With the application of external wall thermal insulation technology in practical projects, the problems existing in external wall thermal insulation are gradually exposed. While paying attention to the thermal insulation effect, the existing external wall thermal insulation boards are also gradually improving their durability, aesthetics and other characteristics. As a building layer that ...
