When；
S3, partial solvent is extracted after 24 hours, is proportionally added into curing agent and stirs and place 1 hour after ten minutes, then add
Enter the diluent being configured, compounder adjusts viscosity, to meet production requirement in due course according to temperature during dispensing；
After the material prepared is filtered with 120 mesh screens before S4, feeding, workshop use can be sent into.
Each component and quality proportioning are as follows in diluent：
CAC:Butyl acetate:PCE:Cyclohexanone=2:1.4:3.6:2.
A kind of spraying method of foldable metal screen optical coating, the spraying method include the following steps：
The inspection of S1, spraying equipment：
It checks the stability of flush coater operation, checks air accumulator, whether the water of spraying engine oil separator discharges；
It is ensured that spray gun and the distance of screen meet technological requirement when S2, dress rifle；
S3, using fabric rush-harvesting and rush-planting spraying method, load control 2.0~2.5Kg/10 ㎡, spraying personnel carefully adjust spray
Rifle load, spraying swath, spray shapes can go up curtain spraying after normal；
During operation, operating personnel must not leave without authorization for S4, flush coater, air pressure must not be adjusted in spraying process, gone out
Doses, spraying swath；
After the completion of S5, screen spraying, screen need to be shaped 30 minutes, curtain can be played after screen surface drying；
It should check whether ground is cleaned before S6, lower curtain, operating personnel should ensure that act face is smooth during lower curtain；
After every piece of screen of cleaning of S7, spray gun spray, spray gun is cleaned in time, prevents ramming material；Spraying terminates daily
Afterwards, spray gun should be put into and washes gunlock and thoroughly cleaned；
S8, screen hanging, which reach 72 hours, to be packed.
The beneficial effects of the invention are as follows：Instant component collocation is reasonable, after being sprayed in screen, can make paint film fastness and
Flexibility improves, and can effectively avoid that the coating of screen is caused to damage in installation, carrying, folding process, it is ensured that fold
Operation is smoothed out.
