The invention discloses a viscosity reducer production technology. The formula comprises the following ingredients: 67% of double-bleached stillingia oil, 5% of aluminum stearate, 6% of polyethylene wax, 10% of vaseline, 5% of bleached beeswax, and 12% of kerosene with a high boiling point. The production technology comprises the following steps: accurately weighing and placing the double-bleached stillingia oil and aluminum stearate into a reaction vessel, and stirring uniformly at normal temperature; rising the temperature to be 180 DEG C, and preserving the heat for 1.5 hours until the solution is transparent; adding polyethylene wax, vaseline and bleached beeswax until the substances are dissolved, preserving the heat for 1 hour, then cooling to be 120 DEG C, crushing high coal, continuously stirring, and then putting the mixture into a vat to be naturally cooled; delivering the product to a finished product workshop, and rolling the product on a three-roller machine for one time in a loose manner, and packaging. The viscosity reducer production technology is simple and convenient to operate; the acid value of the product is less than or equal to 5, the mobility is 32-42 mm per 35 DEG C, and the yield is larger than or equal to 97%; the production efficiency is improved, and the qualified rate of the product is increased.
