Abstract

The invention discloses a wall thermal insulation slurry and a preparation method thereof, which is characterized in that it comprises the following raw materials in parts by weight: 20-35 parts of bentonite, 10-20 parts of vermiculite powder, and 15-20 parts of perlite? 10-15 parts of powdery lime, 5-10 parts of calcium hydroxide, white cotton? 5~10 parts, 5~8 parts of aluminum silicate fiber, 1~3 parts of thixotropic agent, fast T? 1~3 parts, 5~10 parts of binder, 15~20 parts of sawdust powder. The wall thermal insulation slurry provided by the invention is suitable for thermal insulation, thermal insulation and energy saving of various building wall surfaces.

Description

technical field [0001] The invention relates to the field of construction slurry, in particular to a wall thermal insulation slurry and a preparation method thereof. Background technique [0002] Wall insulation is a new type of wall material developed in recent years, which can save a lot of wall materials, improve wall insulation performance, save resources and reduce environmental pollution. With the in-depth development of building energy-saving work, external wall insulation technology is widely implemented in new construction and old building renovation projects. To create an energy-saving project, the key to truly realizing energy saving is to choose high-quality thermal insulation slurry. [0003] In the prior art, the thermal insulation materials for building exterior walls are generally organic materials (such as polyurethane, polystyrene thermal insulation boards, etc.), although the thermal insulation effect is good, but the fire protection level is low, and spa...

Problems solved by technology

[0003] In the prior art, the thermal insulation materials for building exterior walls are generally organic materials (such as polyurethane, polystyrene thermal insulation boards, etc.), although the thermal insulation effect is good, but the fire protection level is low, and sparks generated by pyrotechnics, electric welding or metal cutting are easy to ignite. Combustible building exterior wall insulation materials, resulting in fire accidents

[0004] At present, in terms of building energy-saving external wall insulation projects, board products such as EPS and XPS are mostly used in the cold northern regions of my country, and polymer mortar insulation products such as rubber powder polystyrene particles, expanded perlite and vitrified beads are mostly used in other places. However, the implementation projects using the above-mentioned board and pulp products have found cracking, hollowing, deformation and other phenomena in different degrees within 1 to 5 years
