Description
Technical field
The present invention relates to technical field of chemical paint, the more particularly, to powdery paints of resistance to plating of wave filter and its preparation
Method.
Background technology
For Modern Satellite communication and land mobile communication system, limited frequency spectrum can not meet the need of people
Ask.And wave filter just as the essential frequency-selecting device of Modern Communication System, its effect becomes increasingly conspicuous the excellent of performance of filter
The bad quality for directly affecting whole communication system.
Therefore the performance indications to passive microwave wave filter propose requirement higher, how to design the filtering of excellent performance
Device, to reduce decay of the system to signal, preferably selects desired signal, suppress various interference signals, it has also become one is worked as
Modern much-talked-about topic.
, using full depositing process, whole wave filter is all silver-plated or copper, uses filter effect and is difficult to reach for conventional filter
To requiring, half depositing process is developed for this, only machine cavity is electroplated, and be using heat insulating coat reduction machine cavity temperature.
Because plating uses high concentration nitric acid and phosphoric acid, and common coating is difficult to bear nitric acid containing high concentration and phosphoric acid plating
Liquid, understands serious discoloration and loses antiseptic power.Experiment shows that once plating can cause aberration more than 3.0, second time electroplating after strip
Aberration is resulted even in more than 5.0, and adhesive force can drop to less than 3 grades.In addition, salt fog performance can decline after plating, it is neutral
Salt spray test was difficult more than 250 hours.

Interval temperature is 100 DEG C, the temperature of the 3rd temperature range is 100 DEG C；Because body series react quickly, once temperature of charge mistake
Height, can cause antedating response, reduce the performance of coating, therefore use heat stepwise.
Step 3：Grinding, filtering, obtain product
Preferably, it is 11 that the extruder uses draw ratio：1 double screw extruder.
Preferably, the material after granulation is ground by air classification mill in the step 3, wherein main mill
4000rpm, secondary mill 2800rpm；Again powder is obtained by the sieving of 220 mesh.
A kind of pair of thermosetting saturated polyester of reactive functionality, including the raw material of following mass fraction is made：20 ~ 25 parts new
Pentanediol, 45 ~ 50 parts of terephthalic acid (TPA)s, 10 ~ 15 parts of M-phthalic acid IPA, 5 ~ 10 parts of trimethylolpropanes.
A kind of method of the thermosetting saturated polyester for preparing above-mentioned double reactive functionalities, it is characterised in that：Including following
Step：
Step one：In a nitrogen environment, the heating of neopentyl glycol, terephthalic acid (TPA), M-phthalic acid and trimethylolpropane is added
Start stirring to 120 DEG C；
Step 2：225 DEG C of insulations are warming up to, insulation starts to shrink after 18 ~ 21 hours, when acid number drops to 40 mg KOH/g, decompression
Water in polycondensation and removing system；
Step 3：15 ~ 20mgKOH/g of hydroxyl value, 28 ~ 32mgKOH/g of acid number are reached, stops reaction, discharging, cooling obtain product.
Preferably, be also added with the step one ethylene glycol, adipic acid one or two；The ethylene glycol, oneself two
The mass fraction of acid is respectively 0.01 ~ 5 part, 0.01 ~ 5 part.
The advantage of the invention is that：Using coating of the invention as the powdery paints of resistance to plating of wave filter, one can be reached
Secondary and second time electroplating accumulation aberration is no more than 1.0, and adhesive force is maintained at zero level.Neutral salt spray test can be by 1000 hours.
In addition, coating of the invention is powder, without VOC, environmental requirement is met.
