Description
Technical field
The present invention relates to the technical fields of water-based anticorrosive paint, and in particular to a kind of waterborne acrylic polyurethane surface paint and its
Preparation method.
Background technique
Presently, there are acrylic polyurethane finish paint be mostly oil paint, oil paint is in use good for people
Health and environment cause greatly to injure.With popularizing for water paint, the discharge of VOC can be largely reduced, is ensured
The health of operator.
Waterborne acrylic polyurethane surface paint on the market there are initial stage poor water resistance, acid resistance is poor the disadvantages of.Short time (one
It) dry paint film encounters continuous rainwater and will lead to paint blister, or prolonged acidic rain water due to paint film acid resistance
Can difference also result in paint film destruction, significantly impact construction progress, thus develop a kind of initial stage it is water-fast it is good, acid resistance is good and resistance to
The Aqueous acrylic urethane's coating waited is extremely urgent.
Summary of the invention
For existing waterborne acrylic polyurethane surface paint there are initial stage poor water resistance, acid resistance is poor the disadvantages of, the present invention
There is provided a kind of initial stage it is water-fast it is good, acid resistance is good, the waterborne acrylic polyurethane surface paint of good weatherability safety and environmental protection and its preparation
Method.
In a first aspect, the present invention provides a kind of waterborne acrylic polyurethane surface paint, it is made of component A and B component, wherein A
Component is made of the component of following parts by weight:
B component is made of the component of following parts by weight:
Waterborne acrylic polyurethane surface paint feature of the invention is also:
Aqueous defoamer is polyether silicone lotion, can long-acting offer defoaming effect.
Aqueous levelling agent is acrylate leveling agent.
Thixotropic agent is bentonite or hydrated magnesium silicate, efficiently solves storage and application property.
Silane coupling agent substantially increases the adhesive force with substrate, and silicon powder significantly improves impermeability, resistance to for initial stage
It is aqueous to have very big booster action.
Further preferably, waterborne acrylic polyurethane surface paint of the invention, is made of component A and B component, wherein component A
It is made of the component of following parts by weight:
B component is made of the component of following parts by weight:
Second aspect, the present invention provide a kind of preparation method of waterborne acrylic polyurethane surface paint, including component A preparation step
Rapid and B component preparation step:
(1) waterborne acrylic polyurethane surface paint component A described in the preparation method comprises the following steps:
By water-based hydroxyl acrylic emulsion, amine neutralizer, aqueous high molecular type wetting dispersing agent, aqueous defoamer, aqueous
Wetting agent, deionized water, pigments and fillers, silicon powder, thixotropic agent are added in cylinder, stir 20-30 under the revolving speed of 500-800r/min
Minute, it is transferred to sand mill grinding, fineness of grind < 20um；Then aqueous flow is slowly added under 500-700r/mi n revolving speed again
Flat agent, polyurethane thickener adjust viscosity, until viscosity 80-85ku；It filters and packages, obtains component A packaging packet；
(2) waterborne acrylic polyurethane surface paint B component described in is the preparation method comprises the following steps: in clean anhydrous environment, by third
Glycol diacetate and dehydrating agent after mixing, are slowly added silane coupling agent and aliphatic under 500-700r/min revolving speed
Isocyanates filters and packages after mixing evenly, obtains B component packaging packet.
Waterborne acrylic polyurethane surface paint of the invention is pressed by the component A packaging packet and B component packaging packet individually packed
Finished product is packaged as according to the proportionate relationship of component A and B component mass ratio 3-8:1.
The application method of finishing coat of the invention are as follows: be stirring evenly and then adding into component A and B component in mass ratio a certain amount of
Deionized water, viscosity are transferred to 30-40 seconds (25 DEG C, apply -4 glasss), and spraying application can be from dry or 80 DEG C are toasted 30 minutes.
Beneficial effects of the present invention:
Waterborne acrylic polyurethane surface paint of the invention have many advantages, such as initial stage it is water-fast it is good, acid resistance is good, weather-proof good.From dry
It one day, directly places and is impregnated in rainwater, paint film is water-fast 10 days, not blistering not loss of gloss.Ageing-resistant performance is excellent: QUVB reaches 1000
Hour, gloss loss < 20%.The present invention is directly diluted with deionized water, avoids the use of solvent, greatly reduces the row of VOC
It puts.
In short, finishing coat of the invention pays special attention to initial stage water resistance, to cope with the burst feelings occurred during practice of construction
Condition, for example, it is overnight rainy, and the initial stage that waterborne acrylic polyurethane surface paint prepared by the present invention largely improves paint film is resistance to
It is aqueous.
