After toluene mix homogeneously, rise high-temperature to 86-90 DEG C, continuously add 0.4-0.7 part tetrabutyl ammonium bromide,
0.07-0.1 part p-tert-Butylcatechol, after stirring, drips 6-9 part butyl acrylate, time for adding
For 16-18min, then liter high-temperature is to 96-99 DEG C, and insulation 3-5h obtains material A；
S2, by weight by 12-14 part material A, double solvents mix homogeneously, rise high-temperature to 86-89 DEG C,
Continuously add 0.1-0.12 part benzoyl peroxide, after stirring, drip 4-5 part n-BMA,
Time for adding is 17-20min, and insulation 6-7h obtains phenol-formaldehyde resin modified；
S3, by weight by 65-70 part phenol-formaldehyde resin modified, 20-23 part hexamethylene diisocyanate, 30-35
After part ethylene glycol, 0.8-1 part triethanolamine, 0.3-0.5 part stannous octoate and acetone mix homogeneously, rise high-temperature
To 82-85 DEG C, evacuation, then liter high-temperature is to 106-110 DEG C, after insulation 3-4h, continues to rise high-temperature
To 116-120 DEG C, after ripening 1-2h, demoulding obtains phenol-formaldehyde resin modified and strengthens polyurethane.
6. according to modified polyurethane metallic paint described in any one of claim 2-5, it is characterised in that modified
Phenolic resin strengthens in the S2 of polyurethane Preparation Method, and double solvents is by Ketohexamethylene, butyl glycol ether by volume
It is mixed to prepare than 4-7:8-10.
