Problems solved by technology

[0005] At present, microcapsules of different core materials, shapes, and sizes can be successfully prepared by selecting the above-mentioned methods and shell materials, but the prepared microcapsules usually have the disadvantages of poor mechanical strength, acid and alkali resistance, etc., which make it difficult to apply in complex applications. Environmental conditions, such as high temperature, high pressure, strong acid or strong alkali, etc.

Embodiment Construction

[0020] 1. Preparation process:

[0021] Accurately weigh a certain mass ratio of dichloromethane, sodium lauryl sulfate, Span 80 and sodium chloride (or cerium oxide, potassium permanganate) in a three-necked flask, stir and react for 10 minutes, then slowly add quantitative The butyl titanate was refluxed for 20 minutes at 70°C, and then a certain amount of polyethylene (or polypropylene, poly-n-butyl acrylate) was added to the reaction device. After continuing the reaction for a period of time, the temperature of the system was lowered to normal temperature (25°C), and a certain amount of mixed solution of n-butyl ether and epoxy resin was slowly added, and the system was stirred and reacted for 2 hours to obtain composite shell-type microcapsules.

[0022] The following specific embodiments help to understand the present invention, but do not limit the content of the present invention.

[0023] The percentage (100%) of each component accounting for the total weight of the ...

Abstract

The invention discloses a preparation method of a composite shell-type microcapsule, belongs to the technical field of novel material production, and also relates to the technical field of chemistry and chemical engineering. According to the invention, epoxy resin with characteristics of high temperature resistance, acid-base resistance, high pressure resistance and the like is joined with a microcapsule core part which is not wrapped with a shell material, and the prepared composite shell-type microcapsule not only has a control release property, but also has certain mechanical intensity, and also has the characteristics of acid-base resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of new material production, and also relates to the technical field of chemistry and chemical engineering. Background technique [0002] Microcapsules are widely used in medicine, food, paint, ink, adhesive and other industries. Microcapsule technology is a technology that uses film-forming materials to embed solid, liquid or gas to prepare a solid particle product. The diameter of the microcapsule is usually micron to nanoscale, the material embedded in the film-forming material is called the capsule core, and the coating formed by the film-forming material on the outside of the microcapsule is called the wall material. When preparing microcapsules, the appropriate wall material should be selected according to the physical properties of the capsule core material. For example, the oil-soluble core material needs to choose a water-soluble wall material, and the water-soluble capsule core should choose an oil...
