Abstract

The invention discloses a flame retardant smoke-suppression type humidity controlling functional coating and a preparation method thereof. The preparation method comprises the following steps of: firstly, preparing a hydrotalcite/poly(sodium acrylate-acrylamide) intercalation composite material component having high humidity capacity, humidity controlling ability and flame retardant property by areversed phase suspension polymerization method; and then adding the intercalation composite material component to styreneacrylate emulsion, inorganic stuffing, auxiliaries and water, and performing thorough stirring and mixing and even dispersion, thereby obtaining the inner wall coating having flame retardant, smoke suppressing and humidity controlling functions. The technical proposal of the invention provides the coating for an indoor building with the flame retardant and smoke suppressing properties and also the environmental humidity controlling function, thereby meeting the requirements of people for the environment comfort, the air quality and the fire-proof safety of the indoor buildings.

Description

technical field [0001] The invention relates to an interior wall coating and a preparation method thereof, in particular to a fire-retardant and smoke-suppressing humidity-regulating functional coating and a preparation method thereof. Background technique [0002] Interior wall paint is an essential building material required for building interior decoration. It is often coated on the surface of interior walls, ceilings, decorative wood panels, furniture and steel structural parts. With the advancement of science and technology and the improvement of people's living standards, people have higher and higher requirements for the comfort, air quality and safety of the indoor building environment, so building materials have gradually begun to "composite, multi-functional, and environmentally coordinated" direction of development. [0003] Like temperature, air humidity is also one of the important environmental parameters that affect the comfort of the indoor environment. A s...
