Abstract

The invention discloses a preparation method of an oil-soluble initiator microcapsule. The preparation method includes the following steps that 1, deionized water, Span-80 and TX-100 are weighed according to a certain mass ratio and added into a reactor; 2, a certain amount of an oil-soluble initiator, aniline and terpene resin are added into the reactor, and an emulsion reaction is carried out for some time at room temperature; 3, a certain amount of ammonium persulfate is added into the reactor, reaction is continued for some time, and the oil-soluble initiator microcapsule is obtained after the mixture is washed three times with ethyl alcohol. The preparation method of the oil-soluble initiator microcapsule is simple, and the prepared microcapsule is high in wrapping rate and good in storage stability and has controllable release time.

Description

technical field [0001] The invention belongs to the technical fields of anaerobic adhesives, coatings, oil field development and chemistry and chemical engineering, and in particular relates to a preparation method of oil-soluble initiator microcapsules. Background technique [0002] Microcapsule technology refers to the use of natural or synthetic polymer coating materials to wrap solid particles, liquid materials or gases with certain dispersibility to form a tiny particle with an obvious "core-shell" structure, which is called microparticles. capsule. The coating material is usually called wall material or shell material, and the material wrapped by the coating material is called capsule core or core material. At present, microcapsule technology has been widely used in food, daily necessities, medicine, chemical industry, oil field and other industries, and has achieved remarkable economic benefits. With the rapid development of nanotechnology, the application field of ...
