Abstract

The invention discloses an anti-sagging heat-insulation mortar based on beta-hemihydrated gypsum. The mortar comprises the following components in parts by weight: 100 parts of beta-hemihydrated gypsum, 5-30 parts of white cement, 60-100 parts of vitrified microsphere, 10-40 parts of quartz sand, 3-10 parts of re-dispersible latex powder, 0.1-0.5 part of cellulose ether, 0.1-0.5 part of poval, 0.05-0.3 part of citric acid, 0.05-0.5 part of polypropylene fiber, 0.05-0.3 part of starch ether, 0.05-0.3 of montmorillonite powder and 120-200 of water. According to the invention, the heat-insulation mortar has extremely good anti-sagging property and good anti-skating property through improvement of heat-insulation mortar components; and the heat-insulation mortar has good workability, thereby greatly improving the construction efficiency and bringing obvious progress for the field of modern building energy conservation materials.

Description

technical field [0001] The invention relates to building energy-saving materials, in particular to thermal insulation mortar. Background technique [0002] Insulation mortar is a kind of pre-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 for building exterior wall insulation, and has 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 slipping often occur during mechanical construction, which brings great inconvenience to the construction, resulting in poor construction performance and low efficiency. Contents of the invention [0003] In view of the deficiencies in the above prior art, the purpose of the present invention is to provide an anti-sag thermal insulation mortar that can effectively prevent problems such as sag...
