Abstract
The invention discloses a kind of aluminium wheels bottom powder coating, the raw material matched by following weight is made：40-100 parts of epoxy resin, ring amidine and polynary 0-8 parts of hydrochlorate dulling and curing agent, 0.6-1 parts of styrax, 10-50 parts of barium sulfate, 0-20 parts of titanium dioxide, 0.8-1.5 parts of acrylic copolymer levelling agent that 30-60 parts of the carboxyl polyester that acid number is 30-60mgKOH/kg, epoxide equivalent are 600-750g/eq.Aluminium wheels bottom of the present invention powder coating has high-leveling, is not necessary to the characteristics of thin polishing can directly spray colored paint, its suitable aluminium wheels surface spraying.
Description
Technical field
The present invention relates to a kind of chemical powder coating, and in particular to a kind of aluminium wheels bottom powdery paints.
Background technology
Powdery paints is due to the performance with energy-conservation, VOC free discharge, and domestic powder coating technology is quickly grown within this several years.
Now with domestic automobile industry fast development, auto parts machinery is more and more with powdery paints, and wherein aluminum wheels of automobiles is sprayed with powder
Also it is widely used in the world, most of to rely on import because of the bottom powder coating used on China's automobile aluminum wheel hub, these bottom powder
Coating has that levelability is poor, price, so in automobile aluminum wheel hub spray coating process, it is necessary to the thin polishing of increase
Process, then could color spray paint.With customer requirement more and more higher, to bottom powder workability requirement also more and more higher, it need to use up
Amount reduces production process, reduces production cost, improves operating efficiency.Therefore develop a kind of high-leveling, be not necessary to thin polishing directly
It is necessary that the automobile aluminum wheel hub special bottom powder coating of colored paint, which can be sprayed,.
The content of the invention
It is an object of the invention to provide it is a kind of have high-leveling, be not necessary to thin polishing i.e. can be with direct spraying colored paint
Ground powder paint for aluminium wheel hub of cars.
A kind of ground powder paint for aluminium wheel hub of cars that the present invention is provided, its component and weight are：
Acid number is 30-60mgKOH/kg 30-60 parts of carboxyl polyester
Epoxide equivalent is 600-750g/eq 40-100 parts of epoxy resin
Ring amidine and polynary 0-8 parts of hydrochlorate dulling and curing agent
0.6-1 parts of styrax
10-50 parts of barium sulfate
0-20 parts of titanium dioxide
0.8-1.5 parts of acrylic copolymer levelling agent.
The technique that said components are made into powdery paints of the present invention is：Each component is pre-mixed by proportioning first, wherein in advance
Incorporation time is 200-250 seconds, and rate of dispersion turns for 800-1000；Then the mixing extrusion at 100-110 DEG C of temperature；Finally
Pulverize and sieve and produce.Coating baking is solidified with 180 DEG C/10mins.
Powdery paints of the present invention has the features such as production cost is low, levelability is high, i.e. can be with direct spraying without thin polishing
Colored paint, is particularly suitable for automobile aluminum wheel hub surface spraying.
