Problems solved by technology

Although many inorganic insulation materials on the market are fireproof, they have high density, high thermal conductivity, and poor water resistance, which are far from energy-saving indicators. Although organic insulation boards have low density, good processability, and good thermal insulation effects, the products It is flammable and has low safety performance

Abstract

The invention discloses a preparation method of a novel powdery external wall thermal-insulation material and a construction method. The novel powdery external wall thermal-insulation material is prepared from calcium stearate, polypropylene fibers, an elastic emulsion, a nano cement additive, self-extinguishing polystyrene granules, a flame retardant, white floating beads, nano-titania, ceramic cotton fibers, alumina silicate fiber cotton, cellulose ether, foamed filaments, sulphate aluminum cement, water, potassium permanganate and hydrogen peroxide. The formula is simple, raw materials are widely sourced and easy to obtain, the preparation method is simple and easy to operate, and the material has high water resistance, scrubbing resistance and bonding strength and is very smooth and fine after a wall is scrapped to be flat and smooth; the brushed wall has magnetism, and the thermal insulation material has the dominant advantages of being free from emission of toxic substances and non-combustible, has the characteristics of safety and environment-friendliness, effectively overcomes the severe defects that traditional thermal-insulation materials are relatively poor in fireproof performance and harmful to environment, eliminates hidden fire risks of thermal insulation engineering during construction and has a wide application range.

Description

technical field [0001] The invention specifically relates to a preparation method and a construction method of a novel powdery external wall thermal insulation material, belonging to the technical field of construction engineering. Background technique [0002] With the advancement of science and technology and the improvement of living standards year by year, thermal insulation materials have become one of the indispensable supplies in people's production and life. In the prior art, a good formula that is both fireproof, light and low in thermal conductivity has not been found. Although many inorganic thermal insulation materials on the market are fireproof, they have high density, high thermal conductivity, and poor water resistance, which are far from energy-saving indicators. Although organic thermal insulation boards have low density, good processability, and good thermal insulation effects, the products It is flammable and has low safety performance. Contents of the...
