Thermal-insulation mortar

Abstract

The invention discloses a thermal-insulation mortar. The thermal-insulation mortar comprises the following components in parts by weight: 30-40 parts of Portland cement, 20-30 parts of glazed hollow beads, 10-15 parts of thermal-insulation aggregates, 5-10 parts of anti-crack materials and 5-10 parts of functional materials. The thermal-insulation mortar has the advantages that the anti-cracking ability is excellent, and common problems that the thermal-insulation mortar is cracked, flaked and the like can be solved; the bonding strength is high, the adhesive force is strong, and the heat preservation and heat insulation properties, the weather resistance, the fire resistance, water resistance, and the frost resistance are excellent; furthermore, the volume stability of the thermal-insulation mortar is good; the thermal-insulation mortar generates volume microdilatancy during condensation and hardening and is not cracked and hollowed; the water resistance is high; the thermal-insulation mortar is aging-resistant and long in service life.

Description

technical field [0001] The invention relates to a thermal insulation mortar, in particular to a vitrified bead thermal insulation mortar, which belongs to the field of construction. Background technique [0002] At present, the country is vigorously developing and promoting environmental protection and energy-saving building structures. The implementation of building energy conservation must greatly improve the thermal performance of maintenance structures, especially external walls. Generally speaking, there are two main energy-saving methods for building maintenance structures: one is to directly select the thermal insulation wall structure; the other is to apply a layer of thermal insulation mortar on the outer layer of the wall. In comparison, the outer layer of the wall is painted with thermal insulation mortar, and the construction is simple, especially for the existing building structure, its advantages are more obvious. Therefore, the method that building exterior ...

AI Technical Summary

Problems solved by technology

At present, there are many kinds of thermal insulation mortars on the market, and their properties are uneven. Most thermal insulation mortars still have poor crack resistance, are prone to cracking, are not easy to construct in winter, set and harden slowly, and have good bonding ability with the substrate Limited, subject to certain restrictions in practical engineering applications
