Description

A kind of waterborne flame retardant anticorrosive paint and preparation method thereof
【Technical field】
The present invention relates to paint preparing technical field, and in particular to a kind of waterborne flame retardant anticorrosive paint and preparation method thereof.
【Background technology】
With the development of society, the enhancing of the environmental consciousness of people, aqueous paint is used by increasing people, it is aqueous Paint be exactly using coating of the water as diluent, without organic solvent, it is poisonous heavy without benzene,toluene,xylene, formaldehyde, free TDI Metal, nontoxic non-stimulated smell is harmless, free from environmental pollution, and paint film is plentiful, sparkling and crystal-clear bright, pliability is good and has Water-fast, wear-resisting, ageing-resistant, color inhibition, fast drying, it is easy to use the features such as.But existing aqueous paint formation paint film is anti- Fiery fire resistance, rustless property are not fine, poor water resistances, it is therefore desirable to develop a kind of anti-flammability, water resistance, rustless property compared with Good aqueous paint.
The most effectual way for improving aqueous paint anti-flammability is to increase fire retardant in paint formulation.At present, common resistance The organic flame retardant of combustion agent (including organic halogenated flame retardant, organic phosphorus flame retardant, organic nitrogenated flame retardant, silicon-type Fire retardant, organic boron flame retardant and expansion type flame retardant), inorganic flame retardant.Inorganic flame retardant have good flame retardation effect, The characteristics of low toxicity, but its addition is big, can frequently result in the hydraulic performance decline of paint, therefore, generally uses at present to fire retardant Modified method come improve fire retardant with paint compatibility.
Hydrotalcite material belongs to anion type laminated compound, hydrotalcite when heated, its constitution water laminated sheet hydroxyl and Interlayer ion is with water and CO2Form abjection, play reduction burning gases concentration, obstruct O2Fire retardation;The structure of hydrotalcite Water, laminate hydroxyl and interlayer ion depart from laminate in different temperature, so as in relatively low scope (200-800 DEG C) Discharge fire retardant matter.During fire-retardant, caloric receptivity is big, advantageously reduces the high temperature produced during burning, can be high as Halogen Smoke inhibition fire retardant, is widely used in the fields such as plastics, rubber, coating.
Dissaving polymer has excellent compatibility with general polymer, and abundant, being easily modified excellent with end group Point, hydrotalcite is incorporated into dissaving polymer, obtains hyperbranched fire retardant, can improve the phase between hydrotalcite and paint Capacitive, energy while flame retardant effect is kept reduces amount of flame-retardant agent and keeps the performance of paint.However, there is presently no phase The research report of pass.
