Abstract
The present invention relates to car paint, specifically a kind of water nano car paint, it includes base-material by mass percentage：Polyester resin 40 50%；Nano-powder：Titanium dioxide 5 10%；Crosslinking agent：Butylated melamines 35 45%；Curing agent：Isocyanates 2 4%；Levelling agent：DAA 2 4%；Defoamer：Dimethyl silicone polymer 2 4%.It is an advantage of the invention that the raw material VOC content used is relatively low, meet the environmental requirement of car paint, and be water paint, it is adaptable.And using cooperatively by crosslinking agent and curing agent, optimize its adhesive force and glossiness.
Description
Technical field
The present invention relates to the processing method of automotive air-conditioning condenser heat exchanger fin, specifically condenser heat exchanger fin.
Background technology
Body of a motor car, into paint film, can play protection and decorative effect using paint spraying.Car paint is that a kind of use will
High and with high content of technology coating variety is sought, mainly including priming paint, floating coating and finish paint.The Water-borne modification process of car paint is
Progressively carried out from bottom to face, early in the 1960s, the developed country such as America and Europe has taken the lead in using aqueous electrophoretic primer, mesh
Preceding priming paint existing more than 90%, which uses to apply in water paint, 88% automobile, also uses aqueous cathode electrodip painting, but the middle painting overwhelming majority
Or solvent-applied type coating.
In order to adapt to environmental requirement, the VOC emission of painting dressing automobiles is reduced, all in active development and environment-friendly type is utilized both at home and abroad
Coating, including water paint, high solid coating and powdery paints etc..Water paint is to replace organic solvent with a large amount of water, is made
The volatile quantity of organic solvent is greatly reduced in production and work progress, so not only improves the building ring of production operation personnel
Border, decreases the volatilization of organic solvent, is an important development direction of environmental protection coating material.But existing product performance is not good enough,
Quality is not high enough.
The content of the invention
For above-mentioned technical problem, the present invention provides a kind of preferable water nano car paint of product combination property.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：A kind of water nano car paint, by quality
Percentages include following component：
Base-material：Polyester resin 40-50%；
Nano-powder：Titanium dioxide 5-10%；
Crosslinking agent：Butylated melamines 35-45%；
Curing agent：Isocyanates 2-4%；
Levelling agent：DAA 2-4%；
Defoamer：Dimethyl silicone polymer 2-4%.
Preferably, the particle diameter of the titanium dioxide is 10-30nm.
It is an advantage of the invention that the raw material VOC content used is relatively low, meet the environmental requirement of car paint, and apply to be aqueous
Material, it is adaptable.And using cooperatively by crosslinking agent and curing agent, optimize its adhesive force and glossiness.
Embodiment
The present invention is described in detail below, illustrative examples of the invention and explanation are used for explaining the present invention herein, but

Polyester resin is mixed, and then adds 45% crosslinking agent and water-thinned nanometer paint is made.By the coating even application on vehicle body, film
About 25 μm of thickness, and 10min is toasted under the conditions of 50 DEG C, 0 grade that adhesive force reaches ISO grades is measured, gloss of film degree is up to 92 °.
Embodiment 4
By mass fraction by particle diameter be 15nm 6% titanium dioxide, 2% isocyanates, 4% DAA, 3% isocyanates and 45%
Polyester resin is mixed, and then adds 40% crosslinking agent and water-thinned nanometer paint is made.By the coating even application on vehicle body, film
About 25 μm of thickness, and 10min is toasted under the conditions of 50 DEG C, 0 grade that adhesive force reaches ISO grades is measured, gloss of film degree is up to 93 °.
Above-mentioned embodiment is used for illustrative purposes only, and is not limitation of the present invention, relevant technical field
Those of ordinary skill, can be so that various changes can be made and modification without departing from the spirit and scope of the present invention, therefore institute
There is equivalent technical scheme also to belong to scope of the invention.
