The invention belongs to the
building material technique field, in particular relates to a building thermal insulating
mortar. The building thermal insulating
mortar is characterized in that the
mortar is composed of
dry powder and water, the
dry powder and water are present in a weight ratio of 1:1.3, when in use, the
dry powder is added to the water and agitated evenly; and the dry
powder is mixed by materials of modified
cement, modified fly ashes, a re-dispersible latex
powder, wood fibers,
polypropylene fibers,
calcium formate, hydroxypropyl methylcellulose, hydrophobic agent, multi-functional auxiliary agent and modified expanded
perlite, materials of the dry
powder include: 500 parts of modified
cement, 160 parts of modified fly ashes, 25 parts of re-dispersible latex powder, 3 parts of wood fibers, 1 part of
polypropylene fiber, 5 parts of
calcium formate, 6 parts of hydroxypropyl methylcellulose, 1 part of hydrophobic agent, 3 parts of multi-functional auxiliary agent and 300 parts of modified expanded
perlite by weight. The building thermal insulating mortar has advantages of strong heat preservation, firm bonding with wall bodies, compression resistance, superior tensile performance, good
weathering resistance,
environmental protection, and excellent
waterproofing, anti-
cracking and shedding prevention properties.
