Novel composite energy-saving heat-preservation material and preparation method thereof

Abstract

The invention discloses a novel composite energy-saving heat-preservation material including the following substances by weight: 3-6 parts of brucite, 5-10 parts of sepiolite, 6-11 parts of perlite, 3-7 parts of sodium metasilicate, 4-8 parts of potassium silicate, 8-12 parts of montmorillonite, 3-7 parts of heavy calcium carbonate, 2-5 parts of a coal gangue powder, 10-15 parts of methyl gallate, 15-20 parts of triisopropanolamine cyclic borate, 5-9 parts of hydroxypropyl cellulose, and 15-20 parts of 2-fluoroanisole. The inorganic filler and the organic components are added in an original formula of an inorganic energy-saving heat-preservation material, and thus the novel composite energy-saving heat-preservation material has good heat preservation effect and flame retardancy and stability simultaneously.

Description

technical field [0001] The invention belongs to the field of energy-saving thermal insulation materials, and in particular relates to a novel composite energy-saving thermal insulation material and a preparation method thereof. Background technique [0002] The rapid development of social industry has led to an increasing global demand for energy. According to incomplete statistics, building energy consumption accounts for about 15-25% of the world's total energy consumption. To alleviate the increasingly tense energy problems, building energy conservation is particularly important. Especially with the rapid development of urbanization in our country, buildings have sprung up like mushrooms everywhere. Doing a good job in building energy conservation is undoubtedly an effective means to save energy and improve utilization. Building energy conservation refers to the rational use and effective utilization of energy in buildings, continuous improvement of energy utilization ef...

Problems solved by technology

Inorganic thermal insulation materials have good fire and flame retardant effects, small deformation coefficient, anti-aging, good stability, and long service life. However, due to their slightly larger bulk density, their thermal insulation efficiency is relatively poor, and the energy-saving effect is not obvious.

Organic thermal insulation materials have a good thermal insulation effect due to their small thermal conductivity. However, there are serious fire hazards in the use of traditional organic building thermal insulation materials.

In recent years, large-scale building fires caused by the use of such organic flammable thermal insulation materials are not uncommon, which have caused hundreds of millions of major economic losses and most personal casualties, seriously threatening people's life safety
