The coating that kind bond performance, wear-and corrosion-resistant are had excellent performance.It is divided according to service performance, generally there is wear-resisting epoxy coating, corrosion-proof ring
Oxygen coating, antistatic epoxy coating, building decoration epoxy coating.
Architectural decoration epoxy coating is generally filled out using macromolecule epoxy resin, toughener, levelling agent, talcum powder white carbon black
Material, curing agent, organic solvent are formulated according to special ratios.It is primarily present following problems: (1) organic present in formula
Solvent is preferable to the dissolubility of epoxy resin and auxiliary agent usually using the moderately polar solution such as toluene, benzene, ethyl acetate, has
Conducive to molecule diffusion, but coating in film forming procedure along with always remaining one after the volatilization of solvent, especially room temperature curing
Quantitative solvent, and evaporation rate is extremely slow, can also detect to remain after many years；(2) fillers such as talcum powder, white carbon black cannot
It enough evenly spreads in paint coatings, reduces the cohesive force of product, it is de- to be easy cracking when being encroached on by moisture content, chemical substance
It falls, affects corrosion resistance, wearability；(3) according to newest HJ2537-2014 " the aqueous painting of environmental labelling product technical requirements
Material " standard interpretation, must not artificially add phthalate, gylcol ether, halogenated hydrocarbons, toluene, two in water paint
Toluene etc. must not exceed 100mg/kg to the substance of human hazard, glycol ether and its esters, and existing coating generallys use neck benzene
Dicarboxylic acid esters require strictly to control as plasticising softening agent, gylcol ether as surfactant.To sum up, existing to build
Build that decoration is difficult to volatilize with epoxy coating there are solvent, dissolvent residual toxicity is big, raw material not enough environmental protection, filler are not can be uniformly dispersed
The problems such as.
The Chinese invention patent of publication No. CN104910759A discloses a kind of waterborne epoxy coatings and preparation method thereof, should
