（2）Prepare dispersion liquid：
Maleic anhydride and polypropylene glycol are pressed 1：5-7 mass ratios are uniformly admixed together to stir 40min with 350r/min rotating speeds,
Then maleic anhydride quality 1.8-2.4% 4- dimethylamino arsenic pyridines are added, 1.5 hours is incubated at 78 DEG C, obtains reaction solution,
Then ammonia is passed through into reaction solution, ammonia intake is 1 with reaction solution volume ratio:3, then be warming up to, 55 DEG C, insulation 3.5 is small
When, produce；
（3）Synthesis：
By step（1）The mixed serum and step of preparation（2）The dispersion liquid of preparation presses 5:1.2-1.6 mass ratio is uniformly mixed into
Together, 80-90 DEG C is then heated to, is incubated 3.5 hours, then using ultrasonication 15min, be then freeze-dried, i.e.,
.
Further, the step（1）Middle zeolite powder is handled by dipping by lye, and zeolite powder is added in alkali lye 55
Soaked 2 hours at DEG C, then filter, be dried to constant weight, then place into and 10min is soaked in deionized water, then carried out again
Filter, is dried to constant weight, grinds, and crosses 500 mesh, you can；The alkali lye pH is 8.5.
Further, the alkali lye is sodium acetate.
Further, the step（2）It is 15mL/min that middle ammonia, which is passed through speed,.
Further, the step（3）Middle ultrasonic power is 550W, frequency 38kHz.
With powdery paints by 1 when powdery paints prepared by the present invention is used with age resister:The mixing of 75-90 mass ratios makes
With.
The present invention has advantages below compared with prior art：The invention provides a kind of powdery paints to be prepared with age resister
Method, after the age resister of preparation is applied in powdery paints, solidification effect is good, and heat-resistant antifriction performance is good, by adding this hair
The age resister of bright preparation, in the dispersiveness and mobility, with powder coating systems for improving powder coating compositions system
Compatibility between composition is good, and the melting time is short after mixing, can significantly improve powdery paints film resistance to ag(e)ing, also simultaneously
The property of its anti-electromagnetic-radiation can be improved to a certain extent.Pass through the high compatibility in powdery paints, additionally it is possible to greatly
