During use, in 130-150 DEG C, quick-drying solidifies 2 minutes.Build controls at 25-30 μm.Then 140 DEG C of slakings 60 minutes in convection oven.
Performance test methods and result as follows:
Prebake conditions (75 DEG C): 25 minutes.After prebake conditions, ink is tack-free.
Rear baking (180 DEG C): 60 minutes.After rear baking, ink non yellowing.
Adhesive force (GB/T9286-1998): 4 grades.
Hardness (GB/T6739-2006): 4H.
Glossiness (GB/T1743-1979): 53.
Welding resistance performance (288 DEG C of solder furnace dipping 10s, three times): start to come off, find that scolding tin enters phenomenon.
Through thermogravimetric test, the heat resisting temperature of the heat-resistant inks of the present embodiment is 350 DEG C.

Through testing the solidification temperature of known the present embodiment at 160 DEG C.
During use, in 160-170 DEG C, quick-drying solidifies 2 minutes.Build controls at 25-30 μm.Then 160 DEG C of slakings 60 minutes in convection oven.
Performance test methods and result as follows:
Prebake conditions (75 DEG C): 25 minutes.After prebake conditions, ink is tack-free.
Rear baking (180 DEG C): 60 minutes.After rear baking, ink non yellowing.
Adhesive force (GB/T9286-1998): 4 grades.
Hardness (GB/T6739-2006): 4H.
Glossiness (GB/T1743-1979): 44.
Welding resistance performance (288 DEG C of solder furnace dipping 10s, three times): start to come off, find that scolding tin enters phenomenon.
Through thermogravimetric test, the heat resisting temperature of the heat-resistant inks of the present embodiment is 350 DEG C.
Known by the test data of above-described embodiment and comparative example, heat-resistant inks of the present invention is at specific β-hydroxy-ethyl acrylate modified melamine-formaldehyde resin, under the synergy of hyperbranched resin and reactive diluent, become refractory layer to have curing rate is fast, solidification temperature, the excellent feature such as heat resistance, soldering resistance, yellowing resistance; So; the high hot temperature degree produced in machine driving can be adapted to completely by described regulating wheel, transmitting gear, turning cylinder, tooth bar and jaw that this refractory layer covers; guarantee that the running of mechanical component is reliable and stable, ensure that tea cooking machine has enough good reliability and durability.
Finally should be noted that; above embodiment illustrates technical scheme of the present invention; but not limiting the scope of the invention; although done to explain to the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
