Abstract
The invention discloses a water environment-friendly expanding type fire-refractory coating and a preparation method thereof, which pertains to the functional coating technical field. The coating of the invention is characterized in that water-based resin latex is taken as a film-forming base material, a composite dehydration foaming agent and a charring agent which have fire prevention and retardation functions are added according to a mixing ratio, a fire-retardation and smoke-inhibiting agent, a reinforcing filler, water and other auxiliary agents are provided as auxiliaries, all the materials are ground and stirred completely to reach an even mixing state, and then the paint of the invention is produced. The effect and benefit of the invention are that a coating layer can form an even foaming layer with good mechanical property under the action of high temperature or a flame, the heat insulation property is good, the flame-retardant time is long, the coating layer is smooth, the water resistance and weather resistance are excellent, the preparation process is simple, and the operation and control are easy. The preparation of the fire-refractory coating takes water as a solvent, thus having no toxic hazard and having an easy, convenient and pollution-free production process, and being a green environmental protection technology. The coating products of the invention are widely used for the fields such as the steel structure, the interior and exterior walls of a building and fire-refractory timber.
Description
Technical field
The invention belongs to the functional paint technical field, relate to a kind of environment-friendly aqueous expansion type fireproof coating and preparation method thereof.
Background technology
Expanding fire-proof paint is under high temperature or flame interaction, the coating charing of acutely foaming, form a spongy carbonaceous layer of flame retardancy than tens times of former thick coatings and even hundred times, break off the direct heating of flame to ground, isolated ground contacts with air, the concentration of the non-flammable gases dilution oxygen that decomposites, thus reach the fire-retardant fireproof purpose.Though the foaming layer of the expanding fire-proof paint in the practical application at present is thicker, physical strength is lower, subsides easily or comes off under air-flow or external force effect, and it is even inadequately to foam, and causes its heat-proof quality decline even loses provide protection.It is simple to the invention provides a kind of technology, the preparation method of nontoxic water expansion fire-proof coating, with dehydration catalyst and whipping agent compound be one, be aided with reinforcing filler, make coating be subjected to the existing certain thickness of expanding layer of thermosetting, good intensity is arranged again, the abscess that forms is even, good heat-insulation effect, have simultaneously film smooth, water-fast weatherable characteristics.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of environment-friendly aqueous expansion type fireproof coating and preparation method thereof, by this method can the processability excellence frie retardant coating, can be widely used in steel construction, building inside and outside wall and fire retarding wood protection.
Technical scheme of the present invention is: be the film forming base-material with the resin aqueous emulsion, interpolation by a certain percentage has composite dewatering whipping agent, char-forming agent, anti-flaming smoke-inhibiting agent, reinforcing filler, auxiliary agent and the suitable quantity of water of fire protection flame retarding effect, and fully ground and mixed forms; During use coating evenly is coated in the substrate surface of handling well, seasoning is solidified.
Effect of the present invention and benefit are to adopt composite flame retardant system, add composite flame-retardant agent with dehydration and foaming dual function, be aided with char-forming agent and toughener again, high temperature or flame interaction can form the even foaming layer of satisfactory mechanical property down, thermal insulation is good, the anti-combustion time is long, and coating is smooth, has good water-fast weathering resistance.Particularly to prepare aqueous fire-proof coating be to be solvent with water to the technology of the present invention, toxicological harmless, and production process is easy to be pollution-free, is the environmental type technology.
