Hydrophobic inorganic gel powder compounded multifunctional insulating mortar, as well as application and preparation method thereof

Abstract

The invention relates to hydrophobic inorganic gel powder compounded multifunctional insulating mortar, as well as application and a preparation method thereof. The insulating mortar comprises the following raw materials: modified light calcium carbonate powder, monox aluminum powder, an acrylic ester emulsion, an organic polymer cementing material and additives; the raw materials are mixed and prepared to obtain the mortar. The method comprises the following steps: sucking the modified light calcium carbonate powder and the monox aluminum powder into a mixing agitation tank for mixing agitation through vacuum negative-pressure equipment; sucking the acrylic ester emulsion, the organic polymer cementing material and the additives into the mixing agitation tank through the vacuum negative-pressure equipment; finally carrying out mixing agitation at the ordinary temperature to prepare the hydrophobic inorganic gel powder multifunctional insulating mortar. The insulating mortar can be added with different fillers, expanded perlite and polystyrene granules according to the requirements of fire-resistant grades, so as to be compounded into thermal insulation mortar materials for the exterior wall and the roof of a building enclosure. The insulating mortar, the application and the preparation method have the advantages that the energy-saving effect is obvious; the waterproof, air-permeable, fire-resistant and thermal insulation abilities are good; the operation such as mortar and sand pulp production and on-site construction is convenient; the production cost and application cost are low.

Description

technical field [0001] The invention relates to a hydrophobic inorganic rubber powder composite multifunctional thermal insulation slurry and its application and preparation method, which is especially suitable for fire prevention, water seepage prevention, ventilation and thermal insulation in buildings, and belongs to the technical field of building enclosure structure energy saving. Background technique [0002] As an important building energy-saving technology, external wall insulation has been highly valued worldwide, and all countries have started the actual implementation of energy-saving indicators for building walls. As people have higher and higher requirements for house heat insulation, it has gradually developed into a systematic building energy-saving technology to improve living comfort, prolong the life of buildings, and reduce the loss of heat and cold air during heating and cooling. So as to achieve the purpose of reducing energy consumption. The existing i...

Problems solved by technology

The existing insulation layer material has single function and no water-repellent function. When using it, it is necessary to add a waterproof coating, which will lead to poor air permeability. Condensation and condensation will occur at the junction of the insulation layer and the plastering layer, resulting in freeze-thaw damage. Or after curing, because of its strong water absorption, it has no waterproof function. Once rainwater seeps into the thermal insulation material, it will not be able to play a thermal insulation role, causing damage to the bonding force of the material and causing the attenuation of the bonding force of each layer of the system. Reduced weather resistance of the system

When liquid water cannot come out of the insulation material, the regenerated organic gelling material will dissolve in the insulation layer, and in the case of direct sunlight, gas will expand or oxidize, causing the material to hollow out and delaminate, burst, and even become moldy Falling off, resulting in an irreparable loss of control of the external insulation quality of the building envelope
