50-60g is warming up to 150-170 DEG C, is kept for temperature 3-5 hours；
B, it is warming up to 180-200 DEG C, whether limpid, be then cooled to 130-150 DEG C if observing liquid, it is kept for temperature 2-4 hours,
C, Following step B is warming up to 210-230 DEG C, this process needs 11-13 hours, after liquid outlet quantity reaches 500-510 g
It carries out negative pressure and vacuumizes operation；
D, M-and P-cresols 300-350g, dimethylbenzene 1150-1250g are added after vacuumizing.
The time vacuumized is 10-20 minutes.
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, by the heating and cooling control process to temperature especially in manufacturing process, so that the enamel-cover prepared
Line paint, the scope of application is especially wide, and any line footpath is all applicable in certain range of viscosities, substantially increases operating performance,
And product quality effectively improves, and effect is very prominent.
