Description
Technical field
The present invention relates to technical field of coatings more particularly to a kind of water varnish and preparation method thereof.
Background technique
With China in Recent Years rapid development of economy, requirement of the people to physical qualities is also constantly improved, aqueous clear
Paint has very strong adhesive force and anti-oxidant, anti-corrosion capability to metal and coating, forms transparent, light in coating surface after solidification
The firm protective film of bright, wear-resisting, flexible and acid and alkali-resistance, has anti-fingerprint, and the performance of anti-temperature, moisture-proof, acid-proof, alkali prevention is plating
Layer surface anticorrosion, the optimal selection of Anti- tarnishing.But the universal viscosity of water varnish is big, and coating layer thickness is not easy to control, after dilution again
The other performance of paint film is influenced, and the glossiness of the protective film of current water varnish formation and transparency are difficult to meet people couple
The high request of varnish, resistance to stone hit performance, have special requirement especially for the cleaning that car surface uses.
Summary of the invention
For existing water varnish viscosity big, constructional difficulties, protection non-uniform film thickness, glossiness and the transparency of formation without
Method meets the problems such as Special use requirement, and the present invention provides a kind of water varnish and preparation method thereof.
To achieve the above object of the invention, the embodiment of the present invention uses the following technical solution:
A kind of water varnish, the component including following mass percent:
Water soluble acrylic acid hydroxy functional group copolymer emulsion 35-45%, water soluble acrylic acid polyester modification functional group copolymer
Lotion 20-25%, crosslinked resin 15-20%, substrate wetting agents 0.2-0.5%, styrax 1-1.5%, defoaming agent 0.2-
0.5%, the deionization of light stabilizer 0.3-0.6%, UV absorbers 0.3-0.6%, dispersing agent 0.2-0.5% and surplus
Water.
Compared with the existing technology, water varnish provided by the invention uses water soluble acrylic acid hydroxy functional group copolymer emulsion
Had with the collocation of water soluble acrylic acid polyester modification functional group's copolymer emulsion using the paint film formed under the action of crosslinked resin
Higher resistance to hitting property of stone and petrol-resistance, and hardness of paint film is high, adhesive force is strong, corrosion resistance is strong.On the other hand, by aqueous acrylamide
It is special that sour hydroxy functional group copolymer emulsion is cross-linked to form in conjunction with water soluble acrylic acid polyester modification functional group copolymer emulsion
Reticular structure is conducive to the styrax Quick-gasifying evaporation in paint film, it is extra in paint film to take away rapidly in the drying process
Water, the bright degree after greatly increasing water varnish drying, then cooperate the effect of light stabilizer and UV absorbers, it mentions significantly
The glossiness and aesthetics of high paint film.
Wherein benzoic main component is diphenylhydroxyethanone, may also suppress the generation of bubble, prickly heat in paint film, is guaranteed
The mirror effect of paint film vitrifying coating surface.
Preferably, the water soluble acrylic acid hydroxy functional group copolymer emulsion is profound new VSC
6800W/47WA；Water soluble acrylic acid polyester modification functional group's copolymer emulsion is profound new VSC
6276w/44WA。
Preferably, the crosslinked resin is high imino group melamine resin.
High imino group melamine resin makes the paint film to be formed have preferable scratch resistance, resistance to as crosslinked resin
Gasoline and bending resistance.
Preferably, the substrate wetting agents are polyether siloxane copolymer, such as tego280.
Preferably, the defoaming agent is non-silicon class defoaming agent, such as BYK011.
Preferably, the light stabilizer is the liquid hindered amine light stabilizer containing amino ether group, such as TINUVIN
123。
Preferably, the UV absorbers are liquid triazines UV absorbers, such as TINUVIN 400.
Preferably, the dispersing agent is the high molecular weight block copolymer solution of the affinity groups containing pigment, such as BYK190.
The present invention also provides the preparation methods of the water varnish.The preparation method, at least includes the following steps:
Step 1 prepares varnish base-material: in mass ratio by water soluble acrylic acid hydroxy functional group copolymer emulsion, aqueous acrylamide
Acid polyester property modifying functional group copolymer emulsion, crosslinked resin, substrate wetting agents, UV absorbers are uniformly mixed；
Step 2 prepares dispersion pulp: styrax, defoaming agent, dispersing agent and deionized water being uniformly mixed and are ground to fineness
