Description
Technical field
The invention belongs to the fields of anticorrosive paint, and in particular to a kind of water-base epoxy anticorrosive paint and its preparation side
Method.
Background technique
There are many invention about aqueous heavy anti-corrosion paint, focus mostly in the aqueous heavy anti-corrosion paint of aqueous epoxy emulsion, few
Number uses other water-based emulsions, these anticorrosive paint performance indicators are different.It is primarily present that water-fast, acid resistance is bad,
Because its compactness is bad；Thumping majority cannot all be adapted to overheat cold place, because it uses lotion single, lotion molecular weight
All having difference, glass transition temperature is also place far from it, thus having adapted to cold, does not just adapt to the place of heat.
Summary of the invention
The technical problems to be solved by the present invention are: it is good to provide a kind of compactness, water resistance for improving water-based anticorrosive paint
Water-base epoxy anticorrosive paint.The water-base epoxy anticorrosive paint can be widely used for vehicle manufacture, ocean platform, coastal facility,
The anticorrosions such as petroleum and petrochemical industry, machining require high field.
In order to solve the above technical problems, technical solution provided by the invention are as follows: a kind of water-base epoxy anticorrosive paint, packet
Component A and B component are included, the component A and B component mass ratio are 100:13；The B component is aqueous super chemical resistance ring
Oxygen curing agent；The component A, by mass fraction, consisting of:
The aqueous epoxy emulsion a1,7000~17000mPa.S of viscosity, 485~555g/mol of epoxide equivalent, Gu
Content 54~56%；
The aqueous epoxy emulsion a2,700~2000mPa.S of viscosity, 500~550g/mol of epoxide equivalent, admittedly contain
Amount 52~55%.
The component A, by mass fraction, consisting of:
The component A presses mass fraction, consisting of:
Second technical problem to be solved by this invention is: providing a kind of preparation side of water-base epoxy anticorrosive paint
Method.
To solve second technical problem, the technical solution adopted is that: a kind of preparation side of water-base epoxy anticorrosive paint
Method, the steps include: by pigment, blanc fixe, mica powder, trbasic zinc phosphate, modified phosphate aluminium, dispersing agent, defoaming agent, wetting agent,
Deionized water mixing, 800~1000 turns/min of revolving speed disperse at least 30min, are transferred in sand mill and are sanded to fineness≤50 μm；
Then aqueous epoxy emulsion a1, aqueous epoxy emulsion a2, levelling agent, rheological agent, graphene, biocide mildewcide, anti-flash rusting is added
Auxiliary agent, 800~1000 turns/min of revolving speed are uniformly mixed and obtain component A；Component A and B component are uniformly mixed in mass ratio again,
Obtain water-base epoxy anticorrosive paint.
Effective effect: it is arranged in pairs or groups and is used using the lotion of two kinds of different molecular weights, pass through a kind of high lotion of molecular weight and molecule
Low lotion collocation is measured, water paint film forming mechanism of crosslinking is can be improved, makes resin that there is better compactness, to improve painting
The mechanical performance of material；According to emulsion polymerization principle, suitable wetting agent is added, keeps emulsion polymerization more uniform, improves coating
Water resistance, resistance to acid and alkali.The total often structure of graphene sheet layer, is layering to form fine and close thermal insulation layer in the coating, obstructs water
Divide the infiltration and infiltration to film, plays the role of physical preservation, graphene surface hydrophobic property strengthens moisture penetration.
