Single-component high-efficiency lightweight interior-wall insulation putty and preparation method thereof

Abstract

The invention discloses single-component high-efficiency lightweight interior-wall insulation putty, which comprises, by weight, 10-20 parts of hydrophobic aluminium-magnesium silicate, 5-10 parts of hydrophobic SiO2 aerogel, 10-20 parts of rock wool, 3-8 parts of bentonite, 0.3-0.6 part of water-soluble thickening cellulose, 0.05-0.2 part of a retarder and 43-72 parts of gypsum. The technical problem to be solved is to provide single-component high-efficiency lightweight interior-wall insulation putty which has low heat conductivity coefficient, good thermal insulation effect and high fire resistance rating and is convenient for construction and a preparation method thereof.

Description

technical field [0001] The invention relates to the field of thermal insulation building materials, in particular to a single-component high-efficiency lightweight interior wall thermal insulation putty and a preparation method thereof. Background technique [0002] In the field of construction, building thermal insulation is an important measure to achieve the strategic goal of sustainable development in my country. Considering the occupation of the area, etc., the external wall insulation system is the most widely used for building thermal insulation at present, but the construction procedure of the external wall insulation is complicated, especially for the thermal insulation transformation of some old buildings, due to the need to re-build scaffolding , and the difficulty of safety management, the opinions of the owners are often not unified. Compared with the external insulation renovation project, the implementation of the internal insulation renovation is more flexib...
