Description

technical field

[0001] The invention relates to a fire-resistant and heat-preserving mortar, which belongs to the field of building materials. Background technique

[0002] Insulation mortar is a kind of ready-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 to construct building surface insulation As a kind of building material, it has the characteristics of energy saving and waste utilization, thermal insulation, aging resistance, low price and convenient construction, etc., and has a wide market demand. At present, there are many kinds of thermal insulation mortars on the market, and their properties are uneven. Most thermal insulation mortars still have the disadvantage of poor fire resistance, which seriously affects the fire performance of buildings. Contents of the invention

[0003] The object of the present invention is to provide a...
