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

Abstract

The invention discloses a vitrified microbead thermal insulation mortar, which comprises the following components in parts by weight: 40-65 parts of Portland cement, 25-35 parts of vitrified microspheres, 10-20 parts of thermal insulation aggregate, and crack-resistant materials 5‑15 parts, 5‑15 parts for functional materials. The thermal insulation mortar of the present invention has excellent anti-crack performance, can overcome common problems such as cracking and shelling of thermal insulation mortar, and has high bonding strength and strong adhesion, and has good thermal insulation, weather resistance, fire and water resistance, and frost resistance. ; And the volume stability of the thermal insulation mortar is good, the volume will expand slightly when it is condensed and hardened, no cracking, no hollowing, strong water resistance, anti-aging, and long 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 ...
