The application relates to the technical field of plugging removing agents for oilfield recovery, in particular to a foamed acid plugging removing system and a preparation method thereof. The foamed acid plugging removing system comprises a foamed acid component, a foaming agent and a gas phase component, and the foamed acid component comprises, in mass ratio, oxalic acid, phosphoric acid, triethanolamine, dimethyl diallyl ammonium chloride, acetic acid, disodium phosphate and sodium nitrite in a mass ratio of (10-12):(3-5):4:2:(1.5-2.5):0.05:0.05:1. The total weight m1 of the foamed acid component and the total weight m2 of the foaming agent satisfy the relationship m1:m2=100:(1.5-2.5). The volume V1 of the gas phase component and the total volume V2 of the foamed acid component satisfy the relationship V1:V2>=40:1. The foamed acid plugging removing system can improve the plugging removing effect of an acid plugging removing agent in a heterogeneous formation, so that the plugging material dissolution rate is above 65%, the dissolution rate is above 1.20g / (m 2 ·h), the foaming multiple is above 4.0, and the stable foaming time is above 420s.

The invention belongs to the technical field of adhesives, and relates to a water-resistant instant adhesive and a preparation method thereof. The invention provides water-resistant instant glue, which is prepared from the following raw materials in parts by mass: 90 to 95 parts of alpha-cyanoacrylate; 3 to 8 parts of a polyacrylate toughening agent; 0.02 to 0.08 part of hydroquinone; 1 to 3 parts of methacryloyloxypropyl double-terminated polydimethylsiloxane; and 0.1 to 0.3 part of triethanolamine phosphate. The invention aims to solve the technical problems that polydimethylsiloxane is favorable for improving the water resistance of the instant glue, but the adhesion speed of the prepared instant glue is slow, and the adhesion strength is severely reduced.

The invention discloses an inorganic-organic coated amorphous soft magnetic material and a preparation method thereof, the inorganic-organic coated amorphous soft magnetic material is obtained by firstly carrying out inorganic coating on an amorphous soft magnetic material through triethanolamine phosphate and then carrying out organic coating through epoxy resin. Through a composite coating system of triethanolamine phosphate and epoxy resin, the salt spray resistance of the material can be effectively improved, and the stability of the amorphous soft magnetic material in a corrosive environment is remarkably enhanced; meanwhile, the coating system is beneficial to reducing the dielectric constant of the material and improving the resistivity, and can synergistically improve the mechanical property and the magnetic property of the material and reduce the magnetic loss. The coating process has the characteristics of simplified flow and convenience in operation, the formed coating layer is uniform, compact and excellent in stability, and the coating process is suitable for large-scale production and has important application value and industrialization potential in the field of high-frequency inductance elements.
