Lightweight filling type thermal insulation mortar

Abstract

Lightweight filling type thermal insulation mortar comprises the following raw materials in parts by weight: 400-450 parts of cement, 300-400 parts of fly ash, 1-3 parts of a foaming agent, 40-50 parts of a water reducing agent and 100-150 parts of water. The foaming agent comprises the raw materials by weight: 10-15 parts of a synthetic surfactant foaming agent, 10-15 parts of a protein foaming agent and 20-30 parts of water. The invention further provides a preparation method of the lightweight filling type thermal insulation mortar. The water reducing agent comprises the raw materials by weight: 1 part of calcium lignosulphonate, 2 parts of sodium lignosulphonate and 1 part of magnesium lignosulphonate. The prepared lightweight filling type thermal insulation mortar can be directly filled without repeated brush coating or waiting for drying; the construction efficiency is improved; by adding the fly ash, the use amount of cement is reduced, and meanwhile, waste utilization is realized, so that more energy is saved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a light-weight filling type thermal insulation 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. A building material used to construct the thermal insulation layer of the building surface. 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 isolation belt to improve the fire protection standard of buildings; the thermal insulation mortar in the prior art is generally attached to the thermal insulation layer of the building surf...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem in the background technology that the thermal insulation mortar in the prior art is generally attached to the thermal insulation layer of the building surface, a layer of thermal insulation mortar is first applied during construction; it is left to rest for more than 24 hours, and the second layer is applied after the first layer is dry; The traditional thermal insulation mortar cannot be used as a filling material to fill the prefabricated wall, which is a technical problem that is quite inconvenient to use. The present invention proposes a light-weight filling thermal insulation mortar. The light-weight filling thermal insulation mortar prepared by the present invention can Direct filling without repainting or waiting for drying; improves construction efficiency
