Example Embodiment

[0027] Examples:

[0028] The invention relates to a preparation process that significantly improves the molding and performance of microcapsules, including five steps: preparation of wall material solution, emulsification of core material, microcapsule formation, microcapsule curing and microcapsule drying, in which:

[0029] (a) Preparation of wall material solution: Weigh the wall material and distilled water. According to mass percentage, the wall material accounts for 3.0% to 5.0% of the total wall material and distilled water. Then put the wall material in distilled water to soak and swell, then heat After insulation for standby;

[0030] (b) Emulsification of the core material: Weigh the core material, then add the emulsifier dropwise, shake to dissolve, mix with the wall material solution mentioned above, place on a constant temperature water bath, mechanically stir and emulsify to obtain an emulsion;

[0031] (c) Formation of microcapsules: the mixture obtained in step (b) is...

Abstract

The invention discloses a preparation process capable of obviously improving the forming condition and performance of microcapsules, which comprises the following steps: preparing wall material solution, emulsifying a core material, forming microcapsules, solidifying the microcapsules and drying the microcapsules. In the preparation process of the wall material solution, the range of the wall material concentration is 3.0 to 5.0 percent, and the wall material concentration is preferably 4.0 percent. In the invention, by controlling the wall material concentration, the sphericity of the microcapsules is improved, namely the forming condition of the microcapsules is improved; and the embedding rate and the release rate of the microcapsules are improved, and consequently the overall performance of the microcapsules is improved.

Description

technical field [0001] The invention relates to a preparation process, in particular to a preparation process for significantly improving the molding and performance of microcapsules. Background technique [0002] Microcapsules are actually small particles that are made up of a material called a wall material that surrounds another material called a core material. On this basis, there are some special types of microcapsules, such as double-core microcapsules, double-wall microcapsules and matrix microcapsules. The encapsulated substance and the capsule wall are two separate phases, which is the characteristic of microcapsules. Microcapsules can not only encapsulate solid powders, but also liquid materials. If a special preparation method is adopted, microcapsules can also encapsulate gas. also. Both hydrophobic and hydrophilic materials can be encapsulated in microcapsules. [0003] The technical research on microcapsules probably started in the 1930s, and achieved sign...
