Embodiment Construction

[0019] In the specific implementation, as long as a set of mortar mixing equipment is purchased, qualified products can be organized. The production sequence is as follows: the first step is to prepare a special admixture; the second step is to prepare a mixed cementitious powder; the third step is to mix the thermal insulation mortar of the present invention. The thermal insulation mortar product of the present invention can be used in a single-component delivery site by adding water and stirring as required. Specifically, in this embodiment, the thermal insulation mortar mixture is prepared according to the following method:

[0020] ① The mixed raw materials of the thermal insulation mortar mixture produced in this embodiment are mixed cementitious powder and vitrified microbeads. According to the volume ratio, mix the cementitious powder: vitrified beads = (V) 1: (V) 4.5. The corresponding mass ratio is: mixed cementing powder: vitrified beads = 1:0.6. The loose bulk densi...

Abstract

The invention discloses a polymer vitrified microsphere building heat-insulating mortar. The preparation of the heat insulating mortar is implemented by the following steps: firstly, preparing a special additive; secondly, preparing mixed cementitous powder; and finally, uniformly mixing the mixed cementitous powder and vitrified microspheres in a weight ratio of 1:0.6 to obtain the polymer vitrified microsphere building heat-insulating mortar. The heat-insulating mortar of the invention, on the premise of meeting national standards in performance, is improved in bonding strength and lowered in manufacturing cost and suitable for use in projects of interior and exterior plastering of mid- and high-rise building walls made of various materials, particularly, projects of old building heat-insulating modification.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a building insulation mortar with polymer vitrified microspheres. Background technique [0002] Building thermal insulation mortar, as one of the thermal insulation materials of the building's outer protective structure, its principle is to add lightweight aggregate to the wall plastering mortar to reduce the density of the mortar and increase the heat resistance of the material. Its composition is mostly composed of cement binder, expanded perlite, foam particles and other light aggregates. However, the existing materials have the defects and deficiencies of poor bonding and binding properties, poor waterproof performance, insufficient strength, easy slag drop, troublesome construction, and high cost. Summary of the invention [0003] In view of this, the purpose of the present invention is to provide a polymer vitrified microbead building thermal insulation mortar, which ...
