Abstract

The invention relates to a light weight thermal insulation dry-mixed mortar, which comprises following raw materials in parts by weight: 20 to 40 parts of cementing material, 60 to 80 parts of light weight aggregate, and 0.5 to 1.5 parts of high performance polymer additive; wherein the cementing material comprises following raw materials in parts by weight: 20 to 40 parts of fly ash and 60 to 80parts of cement; the light weight aggregate is pitchstone vitrified micro beads; and the high performance polymer additive comprises following raw materials: organic silicone resin, hydroxypropyl methyl cellulose ether, VAE dry powder, polycarboxylic acid water reducer dry powder, and an early strength agent. The light weight thermal insulation dry-mixed mortar has the advantages of light weight,thermal insulation property, good fireproof performance, good caking property, good bleeding resistance, aging resistant property, green, environmental friendliness, resistance to biological biting, prolonged service life, high strength, high flexibility, and strong cracking resistant performance.

Description

technical field [0001] The invention relates to dry powder mortar, in particular to a light-weight thermal insulation dry powder mortar. 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. Inorganic thermal insulation mortar material thermal insulation system is fireproof and non-combustible. It can be widely used in dense residential buildings, public buildings, large public places, flammable and explosive places, and places with strict fire protection requirements. It can also be used as a fire barrier construction to improve building fire protection standards. There are two main types of thermal insulation mortar on the market: 1. Inorganic thermal insulation mortar (vi...
