Description

Emulsive reactive epoxy polymer compositions on the spot
The present invention relates to contain the emulsive reactive epoxy polymer compositions in water of a kind of poly-epoxy emulsion and a kind of emulsive reactive polymer curing composition.On the other hand, the present invention relates to a kind of method for preparing the active polymer compositions of this emulsifying water.The present invention also relates to the cured coating that is formed at an enterprising single step reaction of substrate that is fit to by the active polymer compositions of emulsifying water on the other hand.
The coating system of two portions epoxy resin-matrix generally contains a kind of curable Resins, epoxy and a kind of this curing agent for epoxy resin that is used for, it is dispersed or dissolved in a kind of solvent usually, and---mainly being organic solvent---makes coating composition, for example pigment and floor sealing agent.Based on the reason of environment, it is disadvantageous using the organic solvent based coating composition of this class.On the other hand, the coating of this class solidified epoxy resin-matrix provides hard and wear-resisting and has been the coating of anti-hydro carbons and aqueous medium.
Developed dissolving or the emulsive water-based resin system in water that contain a kind of Resins, epoxy and a kind of solidifying agent, and less to environment and health affected.The exploitation of this class system see the polymkeric substance of Chou tint magazine (Polymers Paint C0lour J0urnal, Vol.184,1994, pp413-417).The water-based resin system has been described in US 4289826, GB-A-1533825 and GB-A-1380108.Described as Chou, known two portions water-based epoxy resin milk sap coating composition has significant disadvantages.Particularly clearly described and lacked in use the amidoamines adducts of dispersion liquid Resins, epoxy or the polyamines of modification: these solidifying agent generally have water-dispersible by making with the salifiable form of VFA.These acid often produce stinks, get rusty and the water sensitive problem fast.Get rusty fast and the water based epoxy priming paint preparation introduction (" Guidelines to Formulation of Waterborne Epoxy Primers ") of corrosive problem at M.A.Jackson, the polymkeric substance magazine (Polymers Paint Colour Journal) of tinting, Oct, 1990, Vol.180, No4270, PP 608-621 and H.Leidheiser, Jr. in organic coating, suppress Corrosion Mechanism (" Mechanism of Corrosion Inhibition with Special Attentionto Inhibitors in Organic Coatings ") about inhibitor, coating technology magazine (Journal of CoatingsTechnology), Oct.1988 has detailed discussion among the pp 97-106.
Thereby be difficult to the milk sap of the stable highly filled low viscosity good fluidity of exploitation usually.In addition, the coating performance that many known architectures show is poor, because in the time of on it being coated in a substrate, there is not its difficult combination of solvent, cause cured coating mechanical flexibility and poor adhesion, porousness height and too high for finishing the required film-forming temperature of ambient cure effect.This class system limited balance between wetting ability and hydrophobicity causes the flexible limited of formulation for coating material.This class system also be subjected to can not be effectively in coating composition in conjunction with the puzzlement of pigment.Therefore, pigment generally mixes with solidifying agent by grinding or stirring.
