Abstract

The invention discloses an anti-sagging heat-insulation mortar based on silicate cement, which comprises the following components in parts by weight: 80-200 parts of silicate cement, 20-50 parts of fly ash, 60-100 parts of vitrified microbeads, 10-20 parts of heavy calcium carbonate, 3-10 parts of redispersible latex powder, 0.1-0.5 part of cellulose ether, 0.1-0.5 part of poly(vinyl alcohol), 0.05-0.3 part of citric acid, 0.05-0.5 part of polypropylene fibers, 0.05-0.3 part of starch ether, 0.05-0.3 part of montmorillonite powder and 120-200 parts of water. According to the invention, the components of the heat-insulation mortar are improved, so that the heat-insulation mortar has the advantages of high sagging resistance, high slipping resistance and good construction performance, thus improving construction efficiency and bringing prominent progress to the energy-saving material field of modern building.

Description

technical field [0001] The present invention relates to building energy-saving materials, in particular to thermal insulation mortar. Background technique [0002] Thermal insulation mortar is a kind of ready-mixed dry powder mortar made of various lightweight materials as aggregate, cement as cementitious material, mixed with some modified additives, and mixed by production enterprises. Mainly used for building exterior wall insulation, with the advantages of convenient construction and good durability. Due to the defects of the components of the current thermal insulation mortar, problems such as sagging and slippage often occur in mechanical construction, which brings great inconvenience to the construction, resulting in poor construction performance and low efficiency. SUMMARY OF THE INVENTION [0003] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide an anti-sag and anti-slip thermal insulation mortar tha...
