Abstract

The invention discloses modified glass bead thermal insulation mortar and a preparation method thereof and belongs to the technical field of building materials. The mortar is prepared from 30-50 partsof portland cement, 5-10 parts of quartz sand, 10-15 parts of kaolin, 20-30 parts of hollow glass beads, 2-3 parts of inorganic mineral powder, 2-3 parts of styrene acrylic emulsion, 4-6 parts of hydroxypropyl methyl cellulose, 3-5 parts of polypropylene short fibers, 3-5 parts of polyvinyl alcohol and 3-5 parts of mono potassium phosphate. According to the modified glass bead thermal insulationmortar, after the glass beads are modified, film with high adhesive strength is formed on the surfaces of the hollow glass beads and has the effects of blocking the hollow glass beads and sealing theincomplete glass beads, the smashing rate of the glass beads is lowered, and accordingly the water absorption rate is lowered. Meanwhile, the polymer film on the surfaces of the hollow glass beads hascertain strength and toughness and has the effect of strengthening the hollow glass beads.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a modified glass bead thermal insulation mortar and a preparation method thereof. Background technique [0002] Building thermal insulation mortar reduces building energy consumption by improving the thermal insulation performance of buildings, which is the most basic way to achieve building energy conservation. Insulation mortar is a kind of ready-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed by the production enterprise. It is mainly used to construct building surface insulation As a kind of building material, it has excellent properties such as thermal insulation, flame retardant, water resistance and weather resistance, and has a wide market demand. [0003] Compared with organic wall insulation materials, vitrified microbead thermal insulation mortar has the advantages of good...
