A thermal insulation mortar of modified expanded perlite

Abstract

The invention provides heat insulation mortar of improved expanded perlite. The heat insulation mortar of improved expanded perlite is prepared from the following raw materials in parts by mass: 100 parts of expanded perlite, 3.5 parts of latex powder, 1 part of water-holding and thickening cellulose, 0.5 part of polypropylene anti-crack fiber, 4 parts of sapwood fiber, 2 parts of phase change powder, 75 parts of ordinary Portland cement and 40 parts of gypsum. The invention has the beneficial effect that the heat insulation mortar of the improved expanded perlite is dry-mixed mortar consisting of expanded perlite as lightweight aggregate, an anti-crack additive, cement, gypsum and other inorganic filling materials. The heat insulation mortar has affinity with multiple building wall bodies, and is easy to construct, and the thickness can reach up to 4-6cm by virtue of one-time painting. The heat insulation mortar is capable of replacing a wall body leveling layer, thus the problem of heat insulation of a wall body is solved, and the building cost is reduced.

Description

technical field [0001] The invention relates to the field of building energy conservation, in particular to a thermal insulation mortar of modified expanded perlite. Background technique [0002] Perlite-vitrified microbead sheet is a non-toxic, harmless and non-polluting green A1-grade inorganic fireproof and thermal insulation material. However, if the perlite-vitrified microbead sheet is not made into a plate, it cannot be directly painted on the wall; This kind of material requires the original wall base to be leveled with mortar in advance, and the flatness of the wall surface is required to be high, otherwise it will directly affect the overall appearance of the exterior wall; it is difficult to supervise the construction process of the board pasting. It is not uncommon for the glue to be glued / no nails or less nails, resulting in low thermal insulation effect, and engineering quality problems are more common; it is difficult to make up the gap between the boards, so i...

It is not uncommon for the glue to be glued / no nails or less nails, resulting in low thermal insulation effect, and engineering quality problems are more common; it is difficult to make up the gap between the boards, so it is difficult to meet the design standard of thermal insulation Effect: Due to the complex construction procedure of the plate, the project cost is increased, and the project party has limited choices
