Microcapsule dispersion stabilizer, microcapsule emulsion and paper for daily use

Abstract

The invention relates to a microcapsule dispersion stabilizer, which comprises a dispersing agent, a lubricating agent and a humectant, wherein the mass ratio of the dispersing agent to the lubricating agent to the humectant is 0.02-1.6: 1-60: 20. When the microcapsule dispersion stabilizer is stirred into microcapsule emulsion, the microcapsule dispersion stabilizer is dispersed between microcapsule particles so as to keep stability of the microcapsule emulsion and dispersion uniformity of the microcapsule particles, wherein through components of the dispersing agent, a gathering trend of the microcapsule particles is reduced and stability of the microcapsule emulsion is kept; components of the humectant have water-lock and moisturized functions, so that the speed of loss of core materials of the microcapsule particles can be reduced, and stability of performances of the microcapsule particles can be ensured in a long-term storage process; and components of the lubricating agent are beneficial to reduce damage of technique processes on microcapsules, such as spraying of the microcapsule emulsion and the like, and improve usability of the microcapsule emulsion. The invention further relates to the microcapsule emulsion and paper for daily use utilizing the microcapsule dispersion stabilizer.

Description

technical field [0001] The invention relates to a microcapsule dispersion stabilizer, a microcapsule emulsion and household paper. Background technique [0002] Microcapsule granulation technology or microcapsule is a technology that embeds and seals solid, liquid or gaseous substances in a micro-gel to become a solid particle product, which can protect the wrapped material from the outside world. Separated from each other to maintain the original color, fragrance, performance and biological activity to the maximum extent, and prevent the destruction and loss of nutrients. [0003] Generally, microcapsules produced and used in fields such as the coating industry usually exist in the form of a suspension. Since the particle size of the microcapsule particles generally ranges from 5 to 200 microns, in the suspension, there will be a large gap between the microcapsule particles. Aggregation is easy to occur, which leads to agglomeration of the microcapsule suspension and affec...

[0003] Generally, microcapsules produced and used in fields such as the coating industry usually exist in the form of a suspension. Since the particle size of the microcapsule particles generally ranges from 5 to 200 microns, in the suspension, there will be a large gap between the microcapsule particles. Aggregation is easy to occur, which leads to agglomeration of the microcapsule suspension and affects the performance of the microcapsule material

Generally, in the process of preparing microcapsules, a dispersant is added to enable the microcapsules to exist stably in the solution in the form of tiny particles. The solution not only needs to maintain good dispersion during long-term storage, but also needs to prevent the microcapsule core material from seeping out of the shell, resulting in the loss of functional materials and the failure of the microcapsules
