Description
Technical Field
The invention relates to the field of preparation of hydrophobic liquid, in particular to hydrophobic liquid with a continuous fragrance releasing effect, and a preparation method and application thereof.
Background
At present, hydrophobic surface modification is widely applied to the fields of industrial application and scientific research such as surface treatment of textiles and micro-channel design of surface tension confinement, and the like.
The basic principle of hydrophobization modification of the surface is that a surface modification layer with hydrophobic property is introduced into the application target surface, and the surface hydrophobic effect of the surface modification layer is amplified through a micron or nano coarse structure of the surface modification layer, so that a good hydrophobic modification effect is realized. For example, Levkin et al synthesized polybutylmethacrylate powders with highly hydrophobic properties by free radical polymerization and applied them to various surfaces to achieve good hydrophobic effect (available from Advanced functional materials, 1009,19, 1993). Although the hydrophobic modification method is low in cost, it is difficult to uniformly apply the modified powder to an irregular surface to affect the hydrophobic modification effect thereof.
The hydrophobic modification by spraying of a hydrophobic liquid is a more effective way to achieve a fast hydrophobic treatment of the surface. Hitoshi Ogihara et al propose a hydrophobic liquid formula based on dodecyl trichlorosilane modified silicon oxide nanoparticles (from Langmuir 2012,28,4605-4608), and experiments prove that hydrophobic modified silicon oxide nanoparticles can be uniformly dispersed to a surface to be modified through a simple solution spraying manner, so that a hydrophobic modification effect is realized. In patent CN201711457970.4, von jen et al proposed a formula of hydrophobic modification liquid composed of absolute ethyl alcohol, water, inorganic micro-nano particles, hybrid siloxane, and fluorosilicone, which can undergo a curing reaction at 80-150 ℃ to form a stable transparent hydrophobic modification layer without affecting the modification surface. In patent CN201510413485.1, trovay et al also reported a modified nanosilica solvent system dispersed in an organic solvent for achieving the formation of a transparent hydrophobic coating on a substrate.
Although the above-mentioned technology can form a hydrophobic coating on the surface of a material in different ways, it is difficult to meet the functional requirements in some use scenarios. For example, in the case of surface treatments on certain interior trim or wall surfaces, it is desirable to incorporate a specific, sustained release fragrance while enhancing the surface hydrophobicity. Aiming at the special functional requirement, the prior art is difficult to realize, so that a functional hydrophobic liquid capable of continuously releasing fragrance and a preparation method thereof need to be provided.
