The present invention provides a low viscosity polyvinyl formal (PVF) paint and a production method thereof, wherein the raw materials comprise a low polymerization polyvinyl formal resin, a phenol formaldehyde resin, an amino resin, blocked toluene diisocyanate, an epoxy resin, phenol (cresol), furfural, xylene and zinc naphthenate. During production, phenol (cresol), furfural and xylene are poured to a reaction kettle, and uniform stirring (300+/- rotation/min) is performed; a low polymerization polyvinyl formal resin and an epoxy resin are poured; heating dissolving is performed, wherein the dissolving temperature is controlled at 60-100 DEG C; after the resins are completely dissolved, a phenol formaldehyde resin, an amino resin, blocked toluene diisocyanate and zinc naphthenate are added; and stirring is continuously performed for 1-2 h, filtration is performed, and the material is discharged. According to the present invention, the produced PVF paint has characteristics of ultra-high ...
