Abstract

The invention discloses an anti-blocking agent, which comprises, by mass ratio, 3 parts to 25 parts of polyethylene glycol (400), 5 parts to 30 parts of dodecanol polyoxyethylene (3) phosphomonoester, 5 parts to 55 parts of crylic acid- malefic anhydride with solid content of 30% to 100%, and 1 part to 35 parts of disodium methylene dinaphthalenesulfonate. The anti-blocking agent is good in performance and little in dosage. Under the normal condition, the anti-blocking agent is added to potassium formate, the potassium formate can keep loose for 3 to 6 months, and The anti-blocking agent can not cause negtive effects on the quality and usage of the potassium formate after addition.The invention also discloses a preparation method and a usage method of the anti-blocking agent.

Description

technical field [0001] The invention relates to an anti-caking agent, in particular to a potassium formate anti-caking agent. Background technique [0002] At present, the total global production capacity of potassium formate in 2010 is 377,000 tons, and the domestic production capacity has reached more than 100,000 tons. It is mainly used in oil drilling, oil field drilling fluid, well completion fluid, surface activity modification of carbon black, deicing agent, mining and other fields. Globally, the application proportion of potassium formate in various fields is 93% in the oil field industry, 2.5% in the deicing agent industry, 1.5% in the leather industry, 1.5% in the printing and dyeing industry, and 1.5% in other industries. The drilling fluid and completion fluid composed of potassium formate fluid has many excellent characteristics: the density can be adjusted at will to meet various actual needs; it has good high temperature stability and strong inhibition; it is...
