D, reach 145-155 DEG C and keep the temperature 1-2 hours, ethylene glycol 100-110g is added in three times in the process, is warming up to
170-190℃；
E, 180 DEG C of heat preservations 1.5-2.5 hours are warming up to, confirmation coating is transparent, this section of liquid outlet quantity 300-310 g,
F, it is initially added into trimellitic anhydride 550-570 g, diphenyl-methane 260-280g when being cooled to 165-170 DEG C, matches gram 125-
130g；
G, it is warming up to 160-170 DEG C, records the time, then heats to 180-200 DEG C, keeps the temperature 1-2 hours,
I, constant temperature 1-2 hours again after being all added, simultaneously sample detection is switched over.
In the step D, feed intake within every minor tick 0.3-0.7 hours.
In the step F, trimellitic anhydride, diphenyl-methane, each point of four parts of additions of match gram.
After above-mentioned formula and method, due to reasonable selection various composition formula and define that various composition is matched
The ratio of side, in addition, being added especially in manufacturing process by substep and optimizing matching to technique, so that preparation
Wire enamel out, while it being used for felt and mould product, effect is very prominent.
