Embodiment
With reference to specific embodiment, the present invention is further detailed explanation.
The present invention can be obtained from the aqueous dispersions of the STW703A solid bisphenol A epoxy resins of Xinhua Resin Factory, Shanghai The coating that covering power is preferable, hardness is higher, and the VOC content of products made thereby is low, VOC≤85g/L, is conducive to the guarantor of environment Shield.
Used additives Tego-902w, BYK two kinds of mixtures works of froth breaking effect auxiliary agent B YK-024 are made in deaeration from TEGO , can be the problem of bubble be excessive effectively in solution system for defoamer.
Selected dispersant is TEGO dispers 760W, Borchi Gen 0851, GEN DFN equal proportion mixing Thing, TEGO dispers 760W are the wetting dispersing agents for water-based printing ink and coating system, and it can reduce grinding strongly Viscosity, and have excellent tinting strength, tinting power, Borchi Gen 0851 are a kind of efficient wetting dispersing agents, using not by pH Value influence, wetting, scattered and stabilization are played to pigment, pigment sedimentation and flocculation can be prevented, so as to extend coating and mill base Useful life, wetting dispersing agent Gen DFN have strong wettability, and three kinds of dispersants are closed and used very much, can be in solution system The sedimentation of grain and coagulation problems, make system keep stable.
The titanium dioxide is rutile type titanium white R818, and the coating manufactured with titanium dioxide is bright in luster, and covering power is high, Strong coloring force, rutile type titanium white R818 can play a protective role to the stability of medium, and it is strong to strengthen the machinery of paint film Degree and adhesive force, prevent crackle, prevent ultraviolet and moisture from passing through, extend the paint film life-span.
Organic pigment selects dark green, and dark green has high-weatherability and stability, and tinting strength, tinting power is high, and lovely luster etc. is excellent Point.
Inorganic pigment selects ultramarine, ultramarine energy high temperature resistant (less than 400 DEG C), alkaline-resisting, and weatherability and light resistance are good, in air In it is extremely stable to Exposure to Sunlight and wind and rain, have brilliance 7~8 grades of lights resistance.
From organobentonite as anti-settling thixotropic agent, organobentonite has good thickening property, thixotropy, suspended surely Qualitative, high-temperature stability, lubricity, film forming, water resistance and chemical stability, can solve the thixotropy of system, improve body The result of prevention of system.
Coalescents select alcohol ester-12, can aid in the film forming of extensive stock emulsion.Effectively reduce its minimum film forming temperature Degree.ED-617F is selected in anti-flash rusting agent, and different from other aqueous sudden strain of a muscle corrosion inhibitors, ED-617F not only plays long-acting sudden strain of a muscle corrosion inhibitor Effect, ED-617F addition can also reduce the consumption of dispersant in formula, effectively improve water resistance, prevent and dodge what is lost (water soluble paint corrosion produced during being dried on iron content base material) is formed, contributes to dry paint Corrosion Protection, suppresses Later stage base material corrosion generation and rust creepage.
Wetting agent Tego-4100 can ground wetting, and can anti-shrinkage cavity, moreover it is possible to promote flowing and antifoam performance.Thickener For Borchi Gel 0620, RM-8W equal proportion mixture, the low sheraing thickeners of Borchi Gel 0620, high PU contents, Without emulsifying agent, water-resistance is excellent;RM-8W is a kind of low smell, not solvent-laden aqueous non-ionic associative type rheology modifier(Dredge Water modified polyurethane)There is provided splendid flowing and levelability, uniform filming performance, showing property of gloss and high thickening efficiency, two While kind being used in mixed way enhancing thickening efficiency, the characteristics of with low taste, environmental protection.This product be for low smell, low VOC it is non-molten The design of formulation coating.
By obtained environment-friendly type aqueous canned motor pump paint special and aqueous epoxy resin curing agent by volume 6:1 collocation mixing Use, the two intermolecular total overall reaction can be made, generate network molecule chain, so that paint film property is stronger, more preferably, improve aqueous The hardness of canned motor pump paint special, adhesive force, weatherability, salt spray resistance.
Preferably, the model STW703B's that aqueous epoxy resin curing agent is produced using Xinhua Resin Factory, Shanghai is aqueous Epoxy curing agent.
