Mortar based on expanded perlite and preparation method thereof

Abstract

The invention discloses mortar based on expanded perlite. The mortar is prepared from the following components in percentage by weight: 40 to 60% of water, 25 to 38% of inorganic cementing material, 8to 15% of heat insulation aggregate, and 3 to 5% of auxiliary material, wherein the inorganic cementing material is prepared from cement, ash calcium powder and fly ash; the heat insulation aggregateis prepared from expanded perlite, vitrified micro bubbles and rubber particles; the auxiliary materials are prepared from anti-cracking fiber, latex powder and an air entraining agent. The inventionalso discloses a preparation method of the mortar based on the expanded perlite. The mortar has the advantages that compared with the polyphenyl particle heat-insulation mortar, the heat insulation property is better; the outstanding strength, anti-deformation ability and durability are realized.

Description

technical field [0001] The application relates to the application of expanded perlite in building insulation materials, in particular to a mortar based on expanded perlite and a preparation method thereof. Background technique [0002] Under the current global background of advocating energy saving and environmental protection, the country is also vigorously promoting energy-saving thermal insulation technologies, such as polystyrene board, extruded board, polyurethane foam thermal insulation technology, etc., which belong to organic thermal insulation, organic and inorganic thermal insulation technology, etc. [0003] Among the existing building materials, the external wall thermal insulation mortar has reduced its material strength and deformation resistance under the condition of considering the thermal insulation performance. Contents of the invention [0004] The object of the present invention is to provide a kind of mortar based on expanded perlite and its preparati...
