Abstract

The invention discloses a heat insulation mortar and a preparation method thereof, and relates-the technical field of cement mortars. The heat insulation mortar comprises 100-150 parts of ordinary Portland cement, 50-80 parts of glazed hollow beads, 50-70 parts of pre-gelatinized starch, 20-50 parts of coated expanded perlite, 20-30 parts of diatomaceous earth, 10-20 parts of modified attapulgite,10-15 parts of rubber particles, 10-15 parts of plant composite fiber, 2-8 parts of water glass, 2-6 parts of carboxymethylcellulose, 2-6 parts of refractory particles, 1-6 parts of an active admixture, 0.2-1.2 parts of a water repellent, 0.2-0.6 part of a physical foaming agent and 100-200 parts of water. The preparation method comprises the following steps: (1) preparing the coated expanded perlite; (2) preparing straw coated particles; (3) preparing a slurry; and (4) preparing the finished product. The heat insulation mortar has the advantages of excellent crack resistance, high bonding strength and strong adhesion.

Description

technical field [0001] The invention relates to the technical field of cement mortar, in particular to a thermal insulation mortar and a preparation method thereof. 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 wall adopts white...
