Abstract
A kind of aqueous automobile finishing coat, comprises the following components in parts by weight: 3.8 ~ 4.7 parts of defoaming agent；32 ~ 35 parts of aqueous acrylic emulsion；1.1 ~ 1.3 parts of PH regulator；23 ~ 27 parts of water-compatible amino resin；1 ~ 1.4 part of anticrater agent；0.7 ~ 1 part of dispersing agent；12 ~ 15 parts of nano-ceramic powder transparent resin；3 ~ 3.9 parts of coalescing agent；5 ~ 7 parts of aqueous polyurethane thickener；12 ~ 15 parts of water；4.7 ~ 5.9 parts of levelling agent；0.8 ~ 1.1 part of fungicide；2.2 ~ 2.4 parts of organic silicon surfactant；1.2 ~ 1.4 parts of adhesion promoter；0.5 ~ 0.7 part of sagging inhibitor；Nanometer Yi Meng is 1.1 ~ 1.5 parts viscous；2 ~ 2.5 parts of aqueous silver paste；2.3 ~ 2.8 parts of water nano mill base.The invention has the following advantages: providing a kind of aqueous automobile finishing coat, by the optimization to component and processing step, the stability of system is improved, mechanical property is good, and protective performance is good, and glossiness is high, and environmental-friendly, bright-colored, plumpness is high；The preparation method of the aqueous automobile finishing coat in the application is simple simultaneously, and process costs are low.
Description
Technical field
The invention belongs to auto body coatings technical fields, and in particular to a kind of aqueous automobile finishing coat, while the present invention is also
It is related to the preparation method of the aqueous automobile finishing coat.
Background technique
Car paint just refers to the coating being painted on the various types of vehicles such as car vehicle body and components, refers generally to the painting of new car
Material and auxiliary material and vehicle repairing coating.Wherein, can be divided by coating form: water paint, solvent based coating, powder apply
Material；It can be divided by working procedure: priming paint, middle paint, finishing coat, finishing varnish etc.；Can be divided by construction method: brush coating, spraying apply
Material, roll coat enamel, dip-coating paint, electrophoretic coating etc. can be divided into according to vehicle body position: chassis paint, body paint etc..
In solvent based coating, high solids coatings and low-solid content coating can be divided by its solid content height, the two
VOC content one low one is high, adapts to different environmental protection standard and area and uses, the mainstream demand of developed country is VOC content at present
Low high solids coatings.Because of its expensive price and almost, the characteristic of Diamond Search is still within the primary stage to powdery paints, now
Mainly on high-end vehicle.In contrast, at present water paint due to its environmental-friendly property, the market demand be in by
The trend that year rises, US and European account for the 70% of water paint market in the demand to water paint in 2015.
Automobile finish is one of body of a motor car paint, and outermost or secondary outer layer positioned at the entire coating of automobile, it is whole
Main decoration and protective effect are played in a coating, determine endurance quality and appearance of coating etc., it is different by selection
The finishing coat of color, automobile finish can make automobile colourful, take on an entirely new look.Since automobile finish is entire paint film outermost one
Layer is secondary one layer outer, and this requires finishing coats to have the performance more perfect than bottom coating, such as glossiness, Anti-cracking, impact resistance,
It also needs simultaneously environmental-friendly.Therefore, the present invention is further studied and improves to aqueous automobile finishing coat.
Summary of the invention
For the above deficiency in the prior art, the present invention provides a kind of aqueous automobile finishing coats, while the present invention also relates to
And a kind of preparation method of aqueous automobile finishing coat.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals.
A kind of aqueous automobile finishing coat, comprises the following components in parts by weight: 3.8~4.7 parts of defoaming agent；Aqueous acrylic emulsion
32~35 parts；1.1~1.3 parts of PH regulator；23~27 parts of water-compatible amino resin；1~1.4 part of anticrater agent；Dispersing agent 0.7~
1 part；12~15 parts of nano-ceramic powder transparent resin；3~3.9 parts of coalescing agent；5~7 parts of aqueous polyurethane thickener；Water 12~
15 parts；4.7~5.9 parts of levelling agent；0.8~1.1 part of fungicide；2.2~2.4 parts of organic silicon surfactant；Adhesive force promotes
1.2~1.4 parts of agent；0.5~0.7 part of sagging inhibitor；1.1~1.5 parts of clay of Yi Meng of nanometer；2~2.5 parts of aqueous silver paste；It is aqueous
