Abstract

The present invention discloses an efficient, energy-saving and thermal insulation mortar used on a wall body, wherein a purpose of the present invention is to solve defects of the existing thermal insulation mortar. The inorganic nanometer gas condensation thermal insulation and heat preservation mortar is prepared by mixing the following components, by weight, 25-55% of portland cement, 5-10% of calcium oxide, 25-65% of inorganic nanometer gas condensation bead particles, 4-8% of redispersible latex powder, 0.01-0.2% of composite fibers, 0.4-0.8% of methyl cellulose ether, and 0.5-1% of an efficient water reducer. The mortar of the present invention has characteristics of excellent thermal insulation, good weathering resistance, good water resistance, good fire resistance, good corrosion resistance, no toxicity, no pollution, and low production cost.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a high-efficiency and energy-saving thermal insulation mortar used on walls. 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. [0003] At present, the insulation mortar used for wall insulation is divided into two types: organic type and inorganic type. Most of the insulation mortars are organic types, such as EPS insulation mortar, polystyrene particle insulation mortar, etc. The invention of publication number CN101229969A discloses a The kind of rubber powder polystyrene particle insulation mortar includes rubber powder material, EPS granular light aggr...
