Exterior wall fireproof emulsion paint

Abstract

The invention belongs to the technical field of building exterior wall materials, and relates to exterior wall fireproof emulsion paint. The paint comprises components of re-dispersible acrylic acid rubber powder, ammonium polyphosphate, water-ground limestone, titanium pigment, barium sulfate, silicon fine-powder, micro glass bead carriers, nano-sized montmorillonite, trimerization, tributyl phosphate, ammonium dihydrogen phosphate, sodium polyacrylate, sodium hexameta phosphate, sodium isopropyl naphthalene sulfonate, Aerosol sodium salt anionic surfactant, disulfonic acid acidified and oxidized sodium decyl dibenzene sulfonate, N-disodium octadecylselyl sulphonatosuccinate, Triton nonylphenol nonionic surfactant, and sodium hydrogen carbonate. The paint is characterized in that: no organic solvent is included; the paint is processed through porous nano-sized filling material film forming, such that an insulating coating with combustion-supporting auxiliary agents and fire retardingfilling material is formed; no precipitation and deterioration occurs during a storing process; when in use, an appropriate amount of water is added to the paint, and the paint can be automatically dispersed and demulsified into an emulsion paint; the paint can be blended into different concentrations according to construction requirements; the paint is applied on an exterior insulating layer, and the paint has functions of temperature maintaining, fire preventing and thermal insulating.

Description

technical field [0001] The invention belongs to the technical field of building exterior wall materials, and in particular provides a fireproof latex paint for exterior walls. Background technique [0002] With the rapid economic development and the advancement of urbanization, high-rise and super high-rise buildings have sprung up like mushrooms. Behind these successes, many problems brought about by urbanization have been highlighted: the space for urban living and working has become narrow, and building safety Problems are hard to prevent, building energy conservation and fire safety contradictions and a series of problems. [0003] As my country's building energy-saving work is fully rolled out in the field of civil buildings, external wall insulation materials have been widely used in buildings. Driven by this, if people cannot strictly control the use of flammable and combustible thermal insulation materials, it will bring huge fire hazards to the society, such as the...

AI Technical Summary

Problems solved by technology

However, the water resistance and moisture resistance of water-based fire retardant coatings are not as good as those of solvent-based fire retardants. At the same time, due to the use of water-based resin emulsion systems, such coatings are greatly affected by the ambient temperature during storage and transportation.

Therefore, it is generally suitable for indoor use, and try to avoid using it in humid places, which greatly limits the scope and method of use of this fire retardant coating.
